The nurse is caring for a client who has diabetic ketoacidosis (DKA). Which of the following would indicate the client is achieving the treatment goals?
Rationale:
Serum pH 7.33 indicates the client is achieving treatment goals for diabetic ketoacidosis (DKA). A pH closer to the normal range of 7.35 to 7.45 reflects improved acid-base balance and indicates effective treatment response in DKA management.
A: Mean arterial pressure (MAP) 71 mmHg does not meet the normal range, indicating potential cardiovascular instability, which is concerning in a DKA management scenario.
B: Potassium 3.3 mEq/L (mmol) [3.5-5 mEq/L] reflects hypokalemia, which can complicate DKA treatment; maintaining potassium within the normal range is critical for patient safety.
C: Blood glucose 255 mg/dL (14.15 mmol/L) signifies hyperglycemia, which is contrary to achieving treatment goals in DKA, where significant glucose reduction is necessary for recovery.
The nurse supervises a graduate nurse caring for a client newly admitted for postoperative management following a thyroidectomy. Which of the following actions by the graduate nurse indicates effective planning of the client's care?
Rationale:
C: The bedside is prepared with a tracheostomy set, oxygen, and suction. This action reflects effective planning for potential airway complications following a thyroidectomy, ensuring immediate intervention is possible if respiratory distress occurs.
A: A bottle of sterile water and petroleum-based gauze does not address the immediate airway management needs post-thyroidectomy, which are critical for patient safety and care.
B: Obtains a prescription for magnesium sulfate does not pertain to postoperative thyroid care and overlooks the priority of airway management in this context.
D: Applies a cervical collar to the client may not be necessary following a thyroidectomy and does not specifically enhance airway protection or address potential complications related to the procedure.
The nurse plans care for a client experiencing a hyperglycemic-hyperosmolar state (HHS). The nurse should anticipate which prescriptions from the primary healthcare provider (PHCP)?
Rationale:
0.9% saline infusion is the appropriate prescription to manage a client experiencing a hyperglycemic-hyperosmolar state (HHS). This solution helps to rehydrate the patient and restore normal fluid balance, which is crucial in HHS treatment.
B: Glargine insulin does not provide the immediate action required in HHS management, as it is a long-acting insulin not suited for acute situations.
C: Sodium polystyrene primarily treats hyperkalemia and does not address the hyperglycemic state or fluid imbalance associated with HHS.
D: Sodium bicarbonate is typically reserved for severe acidosis rather than the hyperglycemic-hyperosmolar state, where fluid and insulin management is the priority.
The following scenario applies to the next 6 items
The nurse in the clinic is caring for a 32-year-old female client.
Item 1 of 6
Nurses' Notes
1559: Client reports to the outpatient clinic with reports of persistent fatigue, weakness, lethargy, and lower back pain over the last 8 months. She is also concerned because she has gained 24 pounds (10.9 kg) over the past 4 months. She stated that the weight gain has been so significant that she developed reddened streaks on her abdomen from the weight gain. The client is concerned because, over the past month, she has noticed she has been drinking more often and has had increased hunger. She has also noticed she is urinating more frequently. She went to urgent care one week ago and tested negative for urinary tract infection. She also noticed that her menstrual cycle has been irregular. She is not on birth control and took a home pregnancy test, which was negative. During the assessment, the client was fully alert and oriented. Clear lung sounds bilaterally. Skin was dry. Excessive facial hair was noted. 1+ pedal and ankle edema bilaterally. Peripheral pulses palpable, 2+, and regular. Body mass index (BMI) of 32. Vital signs: T 97.5° F (36.4° C), P 93, RR 18, BP 145/93, pulse oximetry reading 96% on room air. She is currently taking escitalopram for persistent depressive disorder.
Laboratory Results
Capillary Blood Glucose
1613: 254 mg/dL [70-110 mg/dL]
Select the client findings that require follow-up.
Rationale:
Capillary blood glucose indicates elevated levels, measuring 254 mg/dL, which necessitates follow-up due to the concern for potential diabetes or hyperglycemia. This finding aligns with the client’s symptoms, such as increased thirst and frequent urination.
B: Peripheral pulse findings show normal pulses, indicating adequate circulation without any immediate concerns that need follow-up.
C: Blood pressure readings at 145/93 indicate hypertension, which requires monitoring but does not suggest immediate intervention as the primary concern.
D: Not taking birth control is a relevant finding but does not warrant urgent follow-up in this clinical context, given the primary focus on metabolic and cardiovascular issues.

For each potential order, click to specify whether the potential order is indicated or not indicated for the client.
Your Selected Order (Tap items to remove)
Available Options (Tap to select in order)
A
Serum hemoglobin A1C
B
24-hour urinary cortisol levels
C
Serum complete metabolic panel
D
Serum clonidine suppression test
E
Serum complete blood count
F
Administration of a prescribed corticosteroid
G
Referral for neurology consultation
Rationale:
Serum hemoglobin A1C, 24-hour urinary cortisol levels, serum complete metabolic panel, and serum complete blood count are indicated for the client. These tests are essential for assessing her metabolic status and potential endocrine disorders, given her symptoms of fatigue, weight gain, increased thirst, and elevated blood glucose levels, which may suggest diabetes or other underlying conditions.
D: Serum clonidine suppression test does not relate to the client’s symptoms or concerns, as it primarily evaluates for conditions like hypertension rather than metabolic or endocrine issues.
F: Administration of a prescribed corticosteroid is unnecessary at this point, as there are no indications of an inflammatory condition or adrenal insufficiency that would warrant steroid treatment.
G: Referral for neurology consultation is not warranted; the client's symptoms and laboratory results point more towards metabolic and endocrine evaluations rather than neurological concerns.
The nurse is teaching a client about diabetes mellitus. Which of the following information should the nurse include?
Rationale:
You will need yearly hemoglobin A1C lab tests. Regular A1C tests are essential for monitoring long-term glucose control in diabetes mellitus, helping to prevent complications and adjust treatment plans effectively based on results.
B: Your diet should consist mostly of simple carbohydrates. Relying primarily on simple carbohydrates can lead to quick spikes in blood sugar levels, making it unsuitable for effective diabetes management.
D: You should take more insulin before exercising. Increasing insulin before exercise can cause dangerous hypoglycemia; careful management of insulin and carbohydrates is crucial during physical activity.
E: Your liver enzymes will be monitored closely. While liver function is important, routine monitoring of liver enzymes is not a standard practice for all diabetes patients unless indicated by specific concerns.
The nurse is creating a teaching plan for a client diagnosed with pheochromocytoma. Which statement, if made by the client, would require follow-up?
Rationale:
It will be very important to reduce the stress in my life. Reducing stress is crucial for clients with pheochromocytoma, as stress can exacerbate symptoms and lead to significant hypertension. Effective stress management can improve overall health and reduce complications associated with this condition.
B: This condition may cause my glucose to decrease. Pheochromocytoma typically leads to increased glucose levels due to catecholamine release, not a decrease, making this statement factually inaccurate.
D: If I feel tired, it is okay for me to have an energy drink. Energy drinks may elevate blood pressure and trigger symptoms, contradicting the need for careful management in pheochromocytoma.
E: Diuretics will be prescribed to help eliminate the fluid I may retain. While diuretics might be considered, they are not a standard treatment for pheochromocytoma and could lead to complications.
A post-adrenalectomy client is admitted to the intensive care unit and is on intravenous hydrocortisone. Which nursing intervention should be included in the client's plan of care?
Rationale:
A: Monitor blood glucose levels frequently. Clients receiving intravenous hydrocortisone are at risk for hyperglycemia due to corticosteroid effects on glucose metabolism, making it essential to frequently assess blood glucose levels for timely management.
B: Keep the client supine for 24 hours. Maintaining a supine position does not address the metabolic implications of hydrocortisone therapy and fails to promote effective recovery or monitoring.
C: Discontinue hydrocortisone once vital signs become stable. Stopping hydrocortisone therapy prematurely can precipitate adrenal insufficiency, jeopardizing the patient’s recovery and overall stability, particularly following adrenal surgery.
D: Educate the client on how to properly clean the wound at home. While wound care is important, it does not pertain to the immediate physiological monitoring required after adrenalectomy and hydrocortisone administration.
The nurse is caring for a client who presents with a blood glucose level of 45 mg/dL (2.4975 mmol/L) [70-110 mg/dL, 4.0-11.0 mmol/L]. Which of the following findings are expected?
Rationale:
Cool and clammy skin is expected due to hypoglycemia, as the body responds to low glucose levels by releasing adrenaline, which can cause vasoconstriction and sweating, leading to this symptom.
A: Blurred vision A decrease in glucose can indeed affect vision, but it typically manifests later in severe cases, making it less immediately expected than other symptoms of hypoglycemia.
B: Increased urinary output Low blood glucose levels usually lead to decreased urinary output, as the body conserves fluids during states of hypoglycemia, contradicting the notion of increased urine production.
E: Orthostatic hypotension This condition is more associated with dehydration or medications impacting blood pressure, rather than directly tied to hypoglycemia, which primarily presents with other symptoms like sweating and palpitations.
The nurse is caring for a client who has diabetes mellitus. Which of the following would indicate the client is achieving the treatment goals?
Rationale:
Hemoglobin A1C 6.7% indicates the client is achieving treatment goals. This value is below the target of 7%, reflecting effective long-term blood glucose management and reducing the risk of diabetes-related complications.
A: Fasting blood glucose 145 mg/dl (8.05 mmol/L) exceeds the normal range, suggesting inadequate blood sugar control and potential risk for acute complications in diabetes management.
B: Creatinine 2.3 mg/dl (203.32 µmol/L) signifies impaired kidney function, which can be a serious concern in clients with diabetes, indicating a significant deviation from healthy parameters.
C: Urine Specific Gravity 1.043 indicates potential dehydration or renal issues, as it is higher than the normal range, suggesting that the client may not be adequately hydrated.
The following scenario applies to the next 1 items.
The nurse in the physician's office is caring for a 41-year-old female client.
Item 1 of 1
Progress Notes
1043
Subjective: Client presents for a follow-up appointment five weeks after she was prescribed sertraline for depressive symptoms. She reports no improvement and even reports worsening as she is having difficulty focusing at work. Specifically, she reports feeling like she is in a 'brain fog.' Two weeks ago, she started taking over-the-counter stool softeners because of constipation, which did not improve even after introducing more fiber in her diet. Finally, she reports that her shoes are no longer fitting because of edema in her ankles and feet.
Objective: Client is alert and oriented to person, place, and time. 2+ peripheral pulses. S1/S2 heart tones. Hypoactive bowel sounds in all quadrants. Clear lung sounds. Trace periorbital and 1+ pedal edema.
Assessment and plan: Will order laboratory testing as this client is showing strong clinical signs of primary hypothyroidism.
Vital Signs
T 97°F (36.1°C) P 58 RR 16 BP 107/65 Pulse oximetry reading 98% on room air
Orders
obtain thyroid panel
discontinue sertraline
The nurse reviews the physician's progress notes, orders, and the client's vital signs. Complete the sentence below with the appropriate answers. If the client has primary hypothyroidism, the client's thyroid panel will have a high...... and low......
Rationale:
High thyroid-stimulating hormone (TSH) and low free thyroxine (T4) levels indicate primary hypothyroidism. The elevated TSH occurs as the pituitary gland attempts to stimulate the underactive thyroid, while low T4 confirms inadequate hormone production.
C: serum triiodothyronine (T3) A low T3 level can occur in various conditions, but it is not a definitive indicator of primary hypothyroidism on its own.
D: thyroid-stimulating hormone (TSH). This option repeats the correct answer but does not address the low T4 that is crucial for diagnosis.
E: free thyroxine (T4). This option incorrectly suggests that T4 would be high in primary hypothyroidism, while it should actually be low due to decreased thyroid function.
F: thyrotropin receptor antibodies (TRAbs). TRAbs are primarily associated with Graves' disease, not with primary hypothyroidism, where autoimmune antibodies play a different role.
The nurse is caring for a client with syndrome of inappropriate antidiuretic hormone (SIADH). The nurse recognizes that SIADH can be caused by which condition?
Rationale:
Small cell lung cancer. This type of cancer is closely associated with the production of antidiuretic hormone (ADH), leading to SIADH. The excessive secretion of ADH causes water retention and dilutional hyponatremia, making it a well-known cause of this syndrome.
B: Tumor on the adrenal medulla. While adrenal tumors can cause various hormonal imbalances, they are not typically linked to the overproduction of ADH associated with SIADH.
C: Inflammation in the nephron. Inflammatory processes in the nephron do not directly stimulate excessive ADH secretion, which is essential for the diagnosis of SIADH.
D: Beta cell destruction in the pancreas. This condition primarily leads to diabetes mellitus and insulin deficiency, which does not relate to the mechanisms causing SIADH.
The nurse is teaching a review course on foods appropriate to treat hypoglycemia. It indicates appropriate understanding if an attendee states that which item should be provided?
Rationale:
1. 1 tablespoon of honey.
2. Honey is a simple carbohydrate that quickly raises blood sugar levels, making it an effective choice for treating hypoglycemia. Its rapid absorption into the bloodstream aids in immediate glucose availability.
3. A: Slice of chicken breast lacks sufficient carbohydrates, which are necessary to promptly elevate blood sugar levels during hypoglycemic episodes.
4. C: 1/2 cup of regular soda contains sugar but may not provide enough rapid glucose response for severe hypoglycemia, as carbonation can slow absorption.
5. D: 1/2 cup of juice is effective, but it may not be as concentrated as honey for immediate treatment, potentially delaying recovery.
6. E: Two hardboiled eggs offer protein but lack the essential carbohydrates needed to swiftly counteract low blood sugar levels in hypoglycemic situations.
The nurse is caring for a client scheduled for an adrenalectomy after being diagnosed with pheochromocytoma. Which preoperative clinical data is essential for the nurse to monitor?
Rationale:
Vital signs are essential for the nurse to monitor in a client scheduled for an adrenalectomy due to pheochromocytoma, as they provide critical information about cardiovascular stability and potential complications.
A: intake and output Monitoring intake and output is important for assessing fluid balance but does not directly reflect the immediate physiological changes related to adrenal surgery and pheochromocytoma.
B: blood glucose While blood glucose levels can be affected by adrenal function, they are not the primary concern in the preoperative phase for adrenalectomy related to pheochromocytoma management.
D: hemoglobin and hematocrit Although hemoglobin and hematocrit provide insight into blood volume and oxygen-carrying capacity, they do not specifically indicate the client's cardiovascular status in this surgical context.
The nurse is conducting health screenings for hypothyroidism at the community health fair. Which client is at the highest risk for this condition? A client who is
Rationale:
D: obese, has periorbital edema, and reports a decrease in motivation. Individuals with obesity and symptoms like periorbital edema and decreased motivation align closely with hypothyroidism, highlighting their vulnerability to this endocrine disorder.
A: underweight, anxious, has a rapid pulse, and reports persistent diarrhea. These symptoms suggest hyperthyroidism rather than hypothyroidism, indicating a different metabolic condition and not a higher risk for hypothyroidism.
B: overweight, reports perspiration while playing sports, and reports feeling cold all the time. While cold intolerance could suggest hypothyroidism, the combination of perspiration during exercise indicates an active metabolism, lowering the risk.
C: obese, has high blood pressure, and has frequent reports of thirst. Frequent thirst may signal diabetes rather than hypothyroidism, making this client less likely to be at risk for thyroid-related issues.
The nurse is counseling a client who has prediabetes. The nurse understands that the client is meeting the treatment goal, as evidenced by
Rationale:
A: total cholesterol of 215 mg/dL (5.55 mmol/L) [ < 200 mg/dL, < 5.2 mmol/L] Elevated cholesterol levels indicate an increased risk for cardiovascular issues, which does not align with the treatment goals for prediabetes management.
B: hemoglobin A1C of 5.4% [ < 6.4%] This result demonstrates effective blood sugar control, indicating the client is below the threshold for diabetes and successfully managing their prediabetes status.
C: fasting blood glucose 128 mg/dL (7.10 mmol/L) [70-110 mg/dL, 4.0-6.0 mmol/L] A fasting blood glucose level above 126 mg/dL suggests impaired fasting glucose, which does not signify achievement of prediabetes treatment goals.
D: random blood glucose of 210 mg/dL (11.66 mmol/L) [70-110 mg/dL, 4.0-6.0 mmol/L] A random blood glucose level exceeding 200 mg/dL indicates poor glucose regulation, contrasting sharply with the desired treatment outcomes for prediabetes.
The nurse is reviewing the diet of the client with hypoparathyroidism. The nurse understands that the client should be on what type of diet?
Rationale:
A: High-calorie, low-calcium diet. This option does not address the essential need for increased calcium intake in hypoparathyroidism, which requires a diet focused on managing calcium levels effectively.
B: Low-calcium, low-phosphorus diet. While phosphorus management is important, hypoparathyroidism requires higher calcium intake, contradicting the low-calcium aspect necessary for adequate treatment and symptom relief.
C: High-phosphorus, low-calcium diet. Increasing phosphorus levels would worsen the condition by further disrupting calcium balance, which is critical to managing hypoparathyroidism effectively and preventing complications.
The nurse is caring for a client who recently had a total parathyroidectomy. Which of the following medications should the nurse anticipate that the primary health care provider (PHCP) will order?
Rationale:
Calcium carbonate. This medication is commonly prescribed after a total parathyroidectomy to help manage calcium levels in the body, as the surgery can lead to hypoparathyroidism and subsequent hypocalcemia.
B: Cholecalciferol Supplementation with vitamin D is not the immediate focus post-surgery; calcium management takes precedence to address the risk of low calcium levels following parathyroid removal.
C: Calcitonin This medication primarily lowers blood calcium levels and is not relevant in the context of post-parathyroidectomy care where calcium replacement is essential.
D: Folic acid This vitamin is unrelated to calcium management or parathyroid function, making it an unsuitable choice for a patient recovering from a total parathyroidectomy.
E: Magnesium oxide While magnesium is important for overall health, it does not directly address the calcium deficiencies often encountered after a parathyroidectomy, thus lacking immediate relevance.
The nurse is caring for assigned clients. The nurse should recognize which client is at risk of developing hypoglycemia? A client
Rationale:
E: who received six units of lispro insulin one hour ago and has not eaten. This client is at significant risk for hypoglycemia due to the timing of insulin administration and lack of food intake, which can lead to an imbalance between insulin levels and glucose availability in the bloodstream.
A: with diabetic ketoacidosis receiving continuous regular insulin intravenously. This client is more likely experiencing hyperglycemia due to DKA, which is counterintuitive to hypoglycemia risk associated with insulin administration.
B: receiving methylprednisolone for an exacerbation of asthma. The use of corticosteroids like methylprednisolone can actually increase blood glucose levels, reducing the likelihood of hypoglycemia in this patient.
C: with pancreatitis and is receiving total parenteral nutrition (TPN). TPN provides a controlled source of glucose, minimizing the risk of hypoglycemia, especially in cases of pancreatitis where oral intake is usually restricted.
D: who is nothing by mouth (NPO) status following a coronary artery bypass graft (CABG). Although this patient is NPO, their metabolic state and monitoring may not indicate immediate hypoglycemia risk, especially if they are receiving IV fluids with glucose.
The nurse is caring for a client prescribed propylthiouracil (PTU). To monitor the effectiveness of this medication, the nurse anticipates the primary healthcare provider will order a
Rationale:
A: serum calcium level. Monitoring serum calcium levels is not relevant to the effects of propylthiouracil, which primarily targets thyroid function rather than calcium metabolism in the body.
B: thyroid panel. A thyroid panel is essential to assess the medication's effectiveness in managing hyperthyroidism, as propylthiouracil inhibits thyroid hormone synthesis and alters thyroid function markers.
C: fasting blood glucose. Fasting blood glucose levels do not provide information related to thyroid hormone levels or the efficacy of propylthiouracil treatment in hyperthyroid patients.
D: white blood cell (WBC) count. While WBC count can indicate infection or bone marrow suppression, it does not directly reflect the effectiveness of propylthiouracil in treating thyroid disorders.
The nurse is caring for a client who reports diarrhea, unintentional weight loss, and nervousness. The primary healthcare provider (PHCP) orders a thyroid panel, and the nurse understands the client is at the highest risk for
Rationale:
The client is at the highest risk for Grave's disease.
Grave's disease is an autoimmune hyperthyroid condition often presenting with symptoms such as diarrhea, weight loss, and nervousness. The thyroid panel ordered by the PHCP will help confirm this diagnosis, as these symptoms align with the overproduction of thyroid hormones characteristic of this disorder.
A: Myxedema A condition resulting from severe hypothyroidism, myxedema does not correlate with the client's symptoms of diarrhea and weight loss, which are indicative of hyperthyroidism instead.
B: Bell's palsy This condition involves sudden facial paralysis and is unrelated to the gastrointestinal and weight-related symptoms reported by the client, focusing instead on neurological issues.
D: Cushing syndrome Characterized by excess cortisol, Cushing syndrome typically results in weight gain and does not align with the symptoms of diarrhea and nervousness presented by the client.
The following scenario applies to the next 1 items
The emergency department (ED) nurse is caring for a 66-year-old male client
Item 1 of 1
History and Physical
2000: 66-year male arrives at the emergency department (ED) following a recommendation by his primary healthcare provider (PHCP). The client called his PHCP in the morning, reporting a headache, feeling unwell, fatigue, and thirst. He could not check his blood glucose because he reports being out of testing supplies for two weeks. He also reports being unable to take his prescribed antihypertensive and antidiabetic medications for one week because he lost his job. On exam, the client reports feeling fatigued and thirsty. He is alert and completely oriented. His physical exam was within normal limits except for a thready pulse with a rate of 119/minute.
The client has a medical history of type II diabetes mellitus, congestive heart failure (CHF), hypertension, and hyperlipidemia. He is prescribed atorvastatin, metformin, and lisinopril.
Vital Signs
Oral Temperature 98o F (36.7o C)
Pulse 119/minute
Respirations 19/minute
Blood pressure 98/52 mm Hg
Oxygen saturation 96% on room air
Physician Orders
Obtain intravenous (IV) access
Five units of regular insulin via intravenous push (IVP)
Infuse two liters of 0.9% saline over one hour
Obtain capillary blood glucose (CBG) every two hours
Potassium chloride 20 mEq by mouth x 1 dose
Implement seizure precautions
The nurse reviews laboratory work ordered by the primary healthcare provider (PHCP). The nurse obtains physician orders for this client with hyperosmolar hyperglycemic state (HHS) . The nurse is preparing to implement the physician's orders. Which order should the nurse clarify with the physician?
Rationale:
Infuse two liters of 0.9% saline over one hour. This order should be clarified because administering such a large volume of fluid rapidly may pose risks for a client with congestive heart failure (CHF), potentially leading to fluid overload.
B: Obtain capillary blood glucose every two hours. Regular monitoring of blood glucose levels is crucial for managing hyperosmolar hyperglycemic state (HHS) and ensures timely interventions based on glucose fluctuations.
C: Potassium chloride 20 mEq by mouth. This order is appropriate as the client may have low potassium levels due to insulin treatment and requires supplementation to prevent cardiac complications.
D: Implement seizure precautions. This order is standard for patients at risk, particularly with altered glucose levels, and helps ensure patient safety during potential seizure activity.
The following scenario applies to the next 1 items
The nurse cares for a client who arrived at the emergency department (ED) complaining of generalized weakness
Item 1 of 1
History and Physical
23-year-male arrives at the emergency department (ED) reporting a headache, feeling unwell, fatigue, and thirst. The symptoms started one day ago and have worsened. He could not check his blood glucose because he reports being out of testing supplies for two weeks.
On exam, the client reports feeling fatigued and thirsty. He is lethargic and completely oriented. His physical exam revealed sunken eyes, skin that was hot to the touch, very dry mucous membranes, with white patches on his tongue.
The client has a medical history of type I diabetes mellitus.
Vital Signs
Oral Temperature 100o F (37.8o C)
Pulse 123/minute
Respirations 24/minute
Blood pressure 94/50 mm Hg
O2 saturation 96% on room air
Complete the sentence below from the list of options. The client is at highest risk of developing....... based on the client's.............
Rationale:
The client is at highest risk of developing diabetic ketoacidosis based on the client's medical history of type I diabetes mellitus and current symptoms indicating severe dehydration and lethargy.
C: diabetic ketoacidosis This option aligns with the client’s type I diabetes and the symptoms of fatigue, thirst, and dehydration, indicating a possible metabolic crisis due to insulin deficiency.
A: hyperglycemic-hyperosmolar state This condition typically occurs in type II diabetes and is less likely given the client’s type I diabetes and acute presentation of symptoms.
B: metabolic alkalosis This condition does not correlate with the client’s symptoms or history, as the primary concerns involve dehydration and potential acidosis rather than alkalosis.
D: positive serum ketones While this may indicate ketoacidosis, it is not a risk condition but rather a potential finding in the diagnosis of diabetic ketoacidosis.
E: glycosylated hemoglobin This measure reflects long-term glucose control and does not address the acute symptoms or risks associated with the client’s current condition.
F: potassium level Although electrolyte imbalances are possible, they do not directly indicate a high-risk condition as does diabetic ketoacidosis in this scenario.
The nurse is performing discharge teaching for a client with Graves' disease. Which of the following client statements indicates effective understanding?
Rationale:
D: I should tell my physician if my blood pressure's top number exceeds 140. This statement demonstrates understanding of Graves' disease management, as monitoring blood pressure is crucial due to potential hypertension associated with the condition.
A: I will take my pulse daily and report a rate less than 60 beats/minute. This reflects a misunderstanding, as Graves' disease typically causes tachycardia, not bradycardia.
B: I am going to add hot yoga to my exercise routine. Engaging in hot yoga may not be advisable due to potential overheating and exacerbation of symptoms in hyperthyroid patients.
C: I will increase the amount of fiber in my diet. While a balanced diet is important, increasing fiber alone does not address the specific needs related to Graves' disease management.
The nurse has received an order to prepare a client for a water deprivation test. The nurse understands that this test is used to diagnose
Rationale:
The water deprivation test is used to diagnose diabetes insipidus (DI). This test assesses the body's ability to concentrate urine and helps differentiate between DI and other conditions affecting water balance.
A: hyperthyroidism This condition primarily affects metabolism and thyroid function, not the regulation of water balance or urine concentration, making it unrelated to the water deprivation test.
B: pheochromocytoma This tumor affects catecholamine production and primarily influences blood pressure and stress responses, lacking any direct correlation with the mechanisms assessed during a water deprivation test.
D: syndrome of inappropriate antidiuretic hormone (SIADH) SIADH involves excessive ADH secretion, leading to water retention and dilutional hyponatremia, contrasting with the water deprivation test's focus on evaluating DI and urine concentration.
The nurse is caring for a client with syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following laboratory tests require careful monitoring?
Rationale:
Sodium levels require careful monitoring. In SIADH, excess antidiuretic hormone leads to water retention, diluting sodium concentration and potentially causing hyponatremia, which can result in serious neurological complications if not managed properly.
A: Potassium Monitoring potassium levels is important, but it is not directly affected by SIADH. The primary concern in this condition revolves around sodium balance due to fluid retention.
C: Glucose While glucose levels are monitored in various conditions, SIADH primarily impacts sodium levels. Glucose does not have a direct relationship with the fluid imbalances characteristic of SIADH.
D: Magnesium Magnesium levels can be important in some disorders, yet SIADH's defining characteristic is its effect on sodium regulation, making magnesium monitoring less critical in this scenario.
The nurse is conducting a health screening at a local health fair. Which of the following should the nurse recognize as a risk factor for developing type II diabetes mellitus?
Rationale:
E: Obesity
Obesity is a significant risk factor for developing type II diabetes mellitus as it leads to insulin resistance and contributes to metabolic dysfunction. Excess fat, particularly visceral fat, plays a crucial role in this increased risk.
A: Gestational diabetes
Gestational diabetes is a temporary condition during pregnancy but does not directly indicate a long-term risk for type II diabetes in individuals who did not have it before.
C: Chronic corticosteroid use
Chronic corticosteroid use can impact glucose metabolism, however, it is not a primary risk factor for type II diabetes when compared to obesity or metabolic syndrome.
D: Gastric bypass surgery
Gastric bypass surgery often leads to weight loss and improved insulin sensitivity, which can lower the risk of developing type II diabetes rather than increasing it.
The nurse is providing discharge instructions to a client who has chronic diabetes insipidus (DI). Which of the following client statements would indicate a correct understanding of the discharge instructions?
Rationale:
I will need to weigh myself at the same time every day. This statement shows understanding of the importance of monitoring weight consistently, which helps assess fluid balance and manage diabetes insipidus effectively.
A: I will need to drink no more than 800 ml per day. This misjudges fluid intake needs, as individuals with diabetes insipidus often require significant hydration due to excessive urination.
C: I should increase salty snacks in my diet. Consuming salty snacks is inappropriate since it may exacerbate fluid retention issues, which are crucial to monitor in diabetes insipidus management.
D: I need to log my daily fluid intake. This indicates awareness of tracking hydration levels, essential for managing diabetes insipidus and preventing dehydration, making it a correct understanding.
The nurse is caring for a client with Cushing's disease. Which of the following complications are associated with this condition?
Rationale:
A, B, D, E. These complications are directly linked to Cushing's disease due to the excess cortisol production, which impacts multiple body systems, leading to increased risks for cataracts, diabetes mellitus, osteoporosis, and venous thromboembolism.
C: orthostatic hypotension This condition is generally associated with adrenal insufficiency rather than Cushing's, where elevated cortisol levels often maintain blood pressure stability rather than cause significant drops.
The nurse is caring for a client with diabetes mellitus (type one) with diabetic ketoacidosis (DKA). Which laboratory result is critical for the nurse to monitor closely during the client's treatment?
Rationale:
Serum potassium. In diabetic ketoacidosis, potassium levels can fluctuate dangerously due to insulin therapy and acidosis, making close monitoring essential to prevent life-threatening complications such as arrhythmias and cardiac arrest.
A: Blood urea nitrogen (BUN) Monitoring BUN is important for renal function assessment, but it does not directly impact the immediate management of DKA compared to potassium levels.
B: Serum creatinine While serum creatinine provides insights into kidney health, it is not as critical as serum potassium in the acute management of DKA and its complications.
D: Serum magnesium Although serum magnesium levels can affect metabolic processes, they are not as crucial for monitoring in the context of diabetic ketoacidosis as potassium levels are during treatment.
The nurse is caring for a client scheduled for a thyroidectomy. The primary healthcare provider (PHCP) prescribes potassium iodide. The nurse understands that this medication is intended to do which of the following?
Rationale:
Potassium iodide is intended to reduce the size and vascularity of the thyroid. This is crucial before a thyroidectomy, as it helps minimize the risk of excessive bleeding during surgery and facilitates a safer procedure.
A: Decrease the risk of agranulocytosis postoperatively. Agranulocytosis is not a direct concern related to potassium iodide, which primarily addresses thyroid size rather than blood cell production.
B: Prevent postoperative hypocalcemia. Potassium iodide does not influence calcium levels; its purpose is to shrink the thyroid rather than manage calcium homeostasis after surgery.
D: Decrease postoperative blood glucose levels. Blood glucose levels are not affected by potassium iodide, which is focused on thyroid gland size reduction rather than metabolic regulation.
The nurse observes the newly hired registered nurse prepare to administer neutral protamine hagedorn (NPH) insulin to a client. Which action by the newly hired nurse requires follow-up?
Rationale:
C: Shaking the insulin vial can introduce air bubbles and alter the insulin's potency. NPH insulin should be gently rolled between the palms to ensure proper mixing without damaging its structure, ensuring safe administration.
A: Asking the client which site the insulin was last injected promotes safe injection practices and helps prevent lipodystrophy, making it an important and appropriate action for the nurse.
B: Checking the client's blood glucose levels prior to administering insulin is essential for ensuring safe and effective treatment. This assessment aids in determining the appropriate dosage and timing of administration.
D: Reminding the client to report symptoms of clammy skin and disorientation is crucial for recognizing hypoglycemia, promoting patient safety, and ensuring timely intervention if blood sugar levels drop dangerously low.
The nurse has administered five units of regular insulin and ten units of NPH insulin. After administering both prescribed insulins, the nurse should assess the client for hypoglycemia
Rationale:
B: The nurse should assess the client for hypoglycemia two to four hours after administering both regular and NPH insulin, as this timeframe aligns with the peak action of these insulins.
A: thirty minutes after administration. This timeframe is too early for assessing hypoglycemia, as insulin action peaks later, making it insufficient for proper evaluation of blood glucose levels.
C: four to six hours after administration. While this period is closer, the peak effect of NPH insulin occurs earlier, warranting evaluation within two to four hours for more accurate monitoring.
D: ten to twelve hours after administration. This duration exceeds the typical peak action times for both insulins, leading to a delay in identifying potential hypoglycemia, which could pose significant risks.
The nurse is caring for a client diagnosed with a myxedema coma. The nurse should anticipate a prescription for which of the following medications?
Rationale:
Levothyroxine. This medication is essential for treating myxedema coma, a severe form of hypothyroidism, as it replenishes thyroid hormone levels, thereby addressing life-threatening symptoms and restoring metabolic balance.
B: Methimazole. This drug is an antithyroid medication intended for hyperthyroidism, not myxedema coma, and does not support the hormonal deficiency present in this life-threatening condition.
C: Tolvaptan. This vasopressin antagonist is used primarily for conditions like hyponatremia and heart failure, offering no therapeutic benefit for a patient experiencing the profound effects of a myxedema coma.
D: Hydrochlorothiazide. As a diuretic, this medication treats hypertension and fluid retention but does not provide any necessary thyroid hormone replacement crucial for managing a myxedema coma.
E: Hydrocortisone. Although it may be prescribed for adrenal insufficiency, it does not address the underlying thyroid hormone deficiency essential in the treatment of a myxedema coma.
The nurse is caring for a client scheduled for a computed tomography (CT) scan with contrast. The nurse recognizes which medication should be held after the procedure?
Rationale:
B: Metformin should be held after the CT scan with contrast due to the risk of lactic acidosis. This condition can arise when metformin interacts with the contrast dye, particularly in clients with compromised renal function.
A: Labetalol does not pose significant risks related to contrast procedures and is primarily used for managing hypertension, thus it can be continued without concern post-scan.
C: Levodopa, utilized for Parkinson's disease management, does not have interactions with contrast agents, making it safe to administer after the CT scan without any complications.
D: Ondansetron, an antiemetic, is not affected by the contrast material and can be given after the procedure to manage any potential nausea without posing additional risks.
The nurse is caring for a client experiencing an adrenal crisis (Addisonian crisis). The nurse should be prepared to administer which intravenous fluid?
Rationale:
0.9% saline is the appropriate intravenous fluid to administer during an adrenal crisis. This solution helps restore blood volume and corrects hyponatremia, which is essential for patients experiencing adrenal insufficiency.
A: Lactated Ringers (LR) While LR is beneficial for various fluid resuscitation scenarios, it may not adequately address the specific electrolyte imbalances and sodium needs in an adrenal crisis.
C: Dextrose 5% in water (D5W) D5W primarily provides free water and glucose, lacking sufficient sodium content to effectively manage the critical needs of a client in adrenal crisis.
D: Dextrose 5% in water and Lactated Ringers (D5LR) Combining these solutions does not prioritize sodium replacement, which is crucial for restoring hemodynamic stability in a client suffering from an adrenal crisis.
The nurse is assisting a client with their newly prescribed insulin pump. The nurse understands which insulin is commonly loaded into the pump?
Rationale:
Rapid acting insulin is commonly loaded into insulin pumps. This type of insulin provides quick glucose control, allowing for flexibility in managing blood sugar levels throughout the day, especially around meals.
B: Ultra long-acting insulin This type of insulin is designed for prolonged duration, making it unsuitable for the rapid adjustments required in an insulin pump setup.
C: Intermediate acting Insulin of this nature has a slower onset and longer duration, which does not align with the immediate needs of insulin pump therapy.
D: Long acting This insulin provides a steady release over time, lacking the prompt action necessary for effective bolus delivery in an insulin pump.
This nurse is caring for a client who is receiving prescribed tolvaptan. Which of the following findings would indicate a therapeutic response?
Rationale:
Urine specific gravity 1.010 indicates a therapeutic response to tolvaptan, as this medication is used to manage conditions related to fluid retention and promotes dilute urine output, demonstrating effective treatment.
A: Fasting blood glucose 100 mg/dL (5.55 mmol/L) shows normal glucose levels but does not directly relate to the effects of tolvaptan, which primarily influences fluid balance rather than glucose metabolism.
C: Total cholesterol 176 mg/dL (4.55 mmol/L) falls within a desirable range; however, this parameter does not reflect the therapeutic impact of tolvaptan, which primarily concerns fluid management and urine concentration.
D: Blood urea nitrogen (BUN) 5 mg/dL (1.785 mmol/L) is below the normal range, indicating potential renal issues or overhydration rather than a positive therapeutic effect of tolvaptan on fluid balance.
The nurse is educating a client about newly prescribed lispro insulin. The nurse should instruct the client to self-administer this insulin
Rationale:
Self-administer lispro insulin 5-15 minutes before a meal. This rapid-acting insulin is designed for immediate absorption, allowing it to effectively manage postprandial blood glucose levels when taken shortly before eating.
A: 30-45 minutes before a meal. This timing is too long for lispro, which is intended to act quickly and align closely with meal intake.
B: One hour after a meal. Administering insulin after eating would lead to inadequate glucose control, as the insulin would not counteract the post-meal rise in blood sugar effectively.
C: 20-30 minutes before a meal. This timeframe is still too extended for lispro's rapid action, potentially resulting in hypoglycemia if the insulin peaks before food intake.
The nurse has obtained a prescription for desmopressin to treat diabetes insipidus (DI). The nurse understands that it is essential to monitor the clients
Rationale:
Monitoring the client's serum sodium level is essential when administering desmopressin for diabetes insipidus. This medication affects fluid balance, and sodium levels can indicate potential complications like hypernatremia or fluid overload.
B: serum glucose. Glucose levels do not directly correlate with desmopressin administration, as this medication primarily regulates water retention rather than impacting blood sugar control.
C: serum magnesium level. Magnesium levels are not directly influenced by desmopressin, which focuses on the body's water balance rather than electrolytes like magnesium.
D: serum calcium level. Calcium levels are unrelated to the action of desmopressin in treating diabetes insipidus, which primarily concerns fluid regulation instead of calcium metabolism.
The nurse is preparing to administer metformin to a client with diabetes mellitus (type two). Which of the following laboratory test results should the nurse monitor during the therapy?
Rationale:
Monitoring vitamin B12 levels is essential during metformin therapy as the medication can lead to decreased absorption of this vitamin, potentially resulting in deficiency and associated complications in patients with type two diabetes.
A: white blood cell (WBC) count Assessing WBC count does not relate to metformin's action or side effects, making it irrelevant for monitoring during diabetes management with this medication.
C: serum uric acid level Metformin does not significantly influence uric acid levels, so monitoring this parameter is unnecessary and does not provide relevant information for patients undergoing metformin therapy.
D: thyroid-stimulating hormone (TSH) level TSH levels are unrelated to metformin treatment, as this medication primarily focuses on glucose regulation and does not directly impact thyroid function or hormone levels.
The nurse is performing discharge teaching for a client prescribed propylthiouracil (PTU). Which client statement indicates effective understanding?
Rationale:
C: I will need to have my liver enzymes monitored while I take this medication. This statement reflects a crucial understanding of propylthiouracil's potential hepatotoxic effects, highlighting the necessity for regular liver function tests to ensure patient safety and medication efficacy.
A: I should increase my intake of foods containing iodine. Increased iodine intake can counteract the intended effects of PTU, which aims to reduce thyroid hormone production, potentially worsening hyperthyroidism.
B: This medication may cause my urine to have a reddish discoloration. Propylthiouracil does not typically cause urine discoloration; this statement indicates a misunderstanding of the medication's side effects and pharmacological profile.
D: If this medication starts to work, I should notice some weight loss. Effective treatment with PTU may stabilize or improve symptoms of hyperthyroidism, but immediate weight loss is not a guaranteed outcome.
