A client diagnosed with DIC is ordered heparin. What is the reason for this medication?
Rationale:
Heparin is ordered to prevent clot formation in a client diagnosed with DIC. This anticoagulant helps inhibit further clot development by interfering with the coagulation cascade, reducing microvascular thrombosis, and preventing organ damage caused by widespread clotting. It addresses the pathological clotting characteristic of DIC, balancing coagulation and fibrinolysis to stabilize the patient's condition effectively.
B: Increase clot formation contradicts the purpose of heparin, which is an anticoagulant. It does not promote clotting but rather inhibits factors involved in the coagulation process, preventing excessive thrombus development.
C: Increased blood flow to target organs is not the direct action of heparin. Although preventing clots may improve perfusion, heparin’s primary role is anticoagulation, not directly enhancing blood circulation.
D: Decrease blood flow to target organs opposes therapeutic goals in DIC. Heparin does not reduce blood flow; rather, it prevents clot-related blockages, aiming to maintain or improve organ perfusion by stopping clot propagation.
Wilma is using a portable suction unit at home, What is the amount of suction required by James using this unit?
Rationale:
Wilma should use 2-5 mmHg suction for James with the portable unit.
Option A is correct because low suction pressure of 2-5 mmHg ensures safe, effective removal of secretions without damaging delicate tissues, maintaining comfort and preventing mucosal injury during home care. This range suits portable units designed for gentle, controlled aspiration in non-clinical settings.
B: 10-15 mmHg applies excessive force potentially causing tissue trauma, unsuitable for portable home suction units requiring gentler pressures.
C: 5-10 mmHg exceeds the recommended minimal suction, risking discomfort and mucosal damage compared to the safer 2-5 mmHg range.
D: 20-25 mmHg is too high for portable units, likely causing harm and discomfort, thus inappropriate for James’s home suction needs.
Kimberly, age 3 years, is being admitted for about 1 week of hospitalization. Her parents tell the nurse that they are going to buy her "a lot of new toys, because she will be in the hospital." The nurse's reply should be based on an understanding of which concept?
Rationale:
Children around age 3 typically require the comfort and reassurance of familiar toys from home during hospitalization. Familiar items help maintain a sense of security and normalcy, reducing anxiety caused by the unfamiliar hospital environment. This understanding guides the nurse's response, emphasizing emotional stability and attachment rather than introducing unfamiliar objects that might increase distress.
A: New toys make hospitalization easier. This is misleading as unfamiliar toys may not provide emotional security, possibly increasing anxiety instead of easing the hospital experience for a young child needing familiarity.
B: New toys are usually better than older ones for children of this age. This generalization overlooks the importance of emotional attachment to familiar toys, which are more effective for reassurance during stressful situations like hospitalization.
D: Buying new toys for a hospitalized child is a maladaptive way to cope with parental guilt. This assumption attributes parental motivations without evidence and ignores the child's developmental need for familiar comfort objects.
A nurse is teaching a parent about administration of iron supplements to a 7-month-old infant. Which should the nurse include in the teaching session? (Select all that apply.)
Rationale:
Administer the iron supplement with a dropper toward the side and to the back of the mouth. This method prevents the infant from swallowing the supplement too quickly, reduces the risk of choking, and helps avoid staining the teeth. Proper administration ensures effective delivery and safety during supplementation. It is a recommended technique for infant iron supplementation.
B: Administer the iron supplement with feedings. Giving iron with feedings can decrease its absorption because certain foods, especially dairy, inhibit iron uptake, reducing the supplement’s effectiveness in treating or preventing iron deficiency anemia.
C: Your infant's stools may look tarry green. Iron supplements typically cause stools to become dark green or black, not tarry, which would suggest gastrointestinal bleeding; thus, this description is inaccurate for expected side effects.
D: Your infant may have some diarrhea initially. Iron supplements more commonly cause constipation or hard stools rather than diarrhea, making diarrhea an unlikely initial side effect from iron supplementation in infants.
While caring for a critically ill child, the nurse observes that respirations are gradually increasing in rate and depth, with periods of apnea. What pattern of respiration will the nurse document?
Rationale:
Cheyne-Stokes respirations describe a pattern of gradually increasing then decreasing rate and depth of breathing, followed by periods of apnea. This waxing and waning pattern is characteristic of serious neurological or cardiac conditions in critically ill patients and matches the nurse’s observations precisely.
A: Dyspnea refers to difficult or labored breathing, not the cyclical pattern of increasing and decreasing respirations with apnea observed here. It describes discomfort rather than a distinct respiratory rhythm.
B: Tachypnea means abnormally rapid breathing but lacks the cyclical increase and decrease in depth and rate, as well as the intermittent apnea that defines the pattern described.
D: Seesaw (paradoxic) respirations involve asynchronous movement of the chest and abdomen, contrasting the synchronous waxing and waning pattern with apnea seen in Cheyne-Stokes respirations.
Which of the following nursing actions is appropriate when a patient returns to his or her room after a bronchoscopy?
Rationale:
The appropriate nursing action is to check for a gag reflex before allowing the patient to drink. This is essential because bronchoscopy involves sedation and local anesthesia, which can temporarily impair the gag reflex, increasing the risk of aspiration if oral intake is resumed too soon without assessment.
A: Ordering a meal immediately overlooks the risk of aspiration since the patient’s swallowing ability may be compromised post-procedure, making immediate feeding unsafe without prior assessment.
B: Encouraging fluids to flush dye is irrelevant here; bronchoscopy typically does not involve contrast dye that requires flushing, so this action does not address post-procedure care.
C: Monitoring for return to consciousness is more applicable immediately post-sedation, but once the patient returns to the room, focus shifts to protective airway reflexes rather than consciousness level alone.
The nurse is explaining the action of insulin to a newly diagnosed diabetic client. During the teaching, the nurse reviews the process of insulin secretion in the body. The nurse is correct when stating that insulin is secreted from the:
Rationale:
Insulin is secreted from the beta cells of the pancreas. Beta cells, located in the islets of Langerhans, are responsible for producing and releasing insulin, which regulates blood glucose levels by facilitating cellular glucose uptake. This physiological function is critical in managing energy and metabolism, especially in diabetic clients who require external insulin supplementation due to impaired secretion or action.
A: Adenohypophysis pertains to the anterior pituitary gland, which secretes hormones like growth hormone and prolactin, not insulin. It plays no direct role in glucose regulation or insulin production.
B: Alpha cells of the pancreas secrete glucagon, which raises blood glucose levels, counteracting insulin’s effects. They do not produce insulin, making this option inaccurate for insulin secretion.
D: Parafollicular cells of the thyroid produce calcitonin, involved in calcium homeostasis, not insulin. Their function is unrelated to glucose metabolism or pancreatic hormone secretion.
During the nursing interview Toni minimizes her visual problems talks about remaining in school to attempt advanced degrees, requests information about full-time jobs in nursing and mentions her desire to have several more children. The nurse recognizes her emotional responses as being:
Rationale:
Toni’s emotional responses demonstrate an example of inappropriate euphoria characteristic of the disease process. This behavior reflects unrealistic optimism and denial of her actual condition, often seen in certain chronic or neurological illnesses. Such euphoria masks the severity of symptoms and impairs insight into her limitations, indicating a psychological defense mechanism tied to the disease rather than genuine emotional well-being or recovery.
B: A reflection of coping mechanisms used to deal with the exacerbation of her illness misinterprets her unrealistic optimism as adaptive coping, overlooking the pathological nature of inappropriate euphoria.
C: Indicative of the remission phase of her chronic illness mislabels denial and euphoria as remission, which typically involves symptom reduction, not distorted emotional responses.
D: Realistic for her current level of physical functioning misunderstands her overly positive statements, which do not align with her actual physical capabilities or prognosis.
Which of the following nursing interventions will help prevent a further increase in ICP?
Rationale:
Elevate the head of the bed helps prevent a further increase in ICP. This position promotes venous drainage from the brain, reducing intracranial pressure by facilitating cerebrospinal fluid and blood flow out of the cranial cavity. Proper elevation between 30 to 45 degrees is a standard nursing intervention to manage ICP and prevent complications related to cerebral edema and increased pressure.
A: Encourage fluids increases overall blood volume, which may elevate intracranial pressure by augmenting cerebral blood flow and fluid accumulation, thus potentially worsening ICP rather than preventing it.
B: Provide physical therapy might stimulate increased metabolic demand and cerebral blood flow, potentially raising ICP, making it unsuitable during acute management of elevated intracranial pressure.
D: Reposition the patient frequently risks sudden changes in venous outflow and cerebral blood flow, which can transiently raise ICP, so it is not advised for preventing increased intracranial pressure.
The nurse is careful to place the incubator away from cold windows or air-conditioning units. This is to conserve the newborn's body heat by preventing heat loss through:
Rationale:
The nurse places the incubator away from cold windows or air-conditioning units to conserve the newborn's body heat by preventing heat loss through radiation. Radiation involves heat loss in the form of infrared rays emitted from the baby's body to cooler nearby surfaces without direct contact, making proximity to cold objects a significant factor in heat dissipation and the need for careful incubator placement.
B: conduction. Heat loss via conduction requires direct contact with a cooler surface, which is not the concern here since the incubator is not touching cold windows or air-conditioning units.
C: convection. Convection involves heat loss through air currents moving around the body, but the focus here is on heat loss without direct air movement, making this less relevant.
D: evaporation. Evaporation causes heat loss due to moisture turning into vapor on the skin, unrelated to the placement of the incubator near cold surfaces.
A client is undergoing test for multiple myeloma. Diagnostic study findings in multiple Myeloma includes:
Rationale:
Bence Jones protein in the urine is a diagnostic finding in multiple myeloma. This protein consists of free light chains produced by malignant plasma cells, which accumulate and are excreted in urine, serving as a key biomarker. Their presence reflects abnormal immunoglobulin production, aiding diagnosis and monitoring disease progression in multiple myeloma patients.
A: A decreased serum creatinine level does not align with multiple myeloma; typically, kidney damage elevates serum creatinine, reflecting impaired renal function.
C: Hypocalcemia contrasts with the hypercalcemia commonly seen in multiple myeloma due to bone resorption from malignant plasma cell activity.
D: A low serum protein level is atypical; multiple myeloma usually causes elevated serum protein from increased monoclonal immunoglobulins.
The single parent of a 3-year-old child who has just been diagnosed with chickenpox tells the nurse that she cannot afford to stay home with the child and miss work. The parent asks the nurse if some medication will shorten the course of the illness. Which is the most appropriate nursing intervention?
Rationale:
The most appropriate nursing intervention is to explain that no medication will shorten the course of the illness. Chickenpox is a self-limiting viral infection, and treatment is primarily supportive. Antiviral medications do not significantly reduce the duration of symptoms in otherwise healthy children, so managing symptoms and preventing complications is the best approach to care.
A: Reassure the parent that it is not necessary to stay home with the child. This overlooks the importance of isolation to prevent spreading the contagious virus to others, making it an inadequate response.
C: Explain the advantages of the medication acyclovir (Zovirax) to treat chickenpox. Acyclovir is not routinely recommended for healthy children as it does not substantially shorten illness duration in typical cases.
D: Explain the advantages of the medication VCZ immune globulin (VariZIG) to treat chickenpox. VariZIG is used for high-risk exposure or immunocompromised patients, not to shorten illness in otherwise healthy children.
. A client with a suspected left sided heart failure is scheduled to undergo a multigated acquisition scan. Which of the following actions is required before undergoing the test?
Rationale:
A client is medicated to relieve cough before the test. This preparation ensures accurate imaging by minimizing motion artifacts caused by coughing, which can interfere with the multigated acquisition scan’s ability to assess cardiac function precisely. Managing cough improves the reliability of ventricular function measurements, critical for evaluating left-sided heart failure, thereby enhancing diagnostic accuracy and patient safety during the procedure.
A: Diuretics are administered This is unrelated to test preparation since diuretics affect fluid balance but do not directly improve imaging quality or reduce motion artifacts during the scan.
B: Client should avoid fluid intake 6 hours Fasting or fluid restriction is not typically necessary for this nuclear cardiac imaging, as hydration status does not significantly impact scan results.
D: Client is administered analgesics Pain relief does not influence the quality or accuracy of the multigated acquisition scan, making analgesic administration irrelevant before the procedure.
The nurse is teaching parents about prevention of urinary tract infections in children. Which factor predisposes the urinary tract to infection?
Rationale:
Short urethra in young girls predisposes the urinary tract to infection. This anatomical feature allows bacteria easier access to the bladder, increasing infection risk. The shorter distance facilitates quicker bacterial ascent, making young girls more susceptible to UTIs. Understanding this helps guide preventive measures, such as proper hygiene and timely voiding, to reduce infection incidence effectively.
A: Increased fluid intake promotes flushing out bacteria, reducing infection risk rather than causing it. More fluids dilute urine and encourage frequent urination, which helps prevent bacterial colonization in the urinary tract.
C: Prostatic secretions in males have antimicrobial properties that protect the urinary tract. They help inhibit bacterial growth, thereby lowering the likelihood of urinary tract infections rather than predisposing one to them.
D: Frequent emptying of the bladder helps eliminate bacteria from the urinary tract. This regular voiding decreases bacterial buildup, serving as a protective factor against infections instead of increasing susceptibility.
Which intervention should the nurse implement to maintain the skin integrity of the preterm newborn?
Rationale:
Cleanse skin with a neutral pH solution only when necessary. This intervention preserves the delicate skin barrier of preterm newborns, minimizing irritation and preventing disruption of the acid mantle. Neutral pH cleansers maintain skin integrity and reduce the risk of infection and breakdown, which harsh soaps and excessive washing could exacerbate in these vulnerable infants with immature skin.
A: Cleanse skin with a gentle alkaline-based soap and water. Alkaline soaps disrupt the acid mantle, increasing skin dryness and vulnerability, which can damage the fragile skin of preterm newborns, leading to irritation and compromised skin integrity.
C: Thoroughly rinse skin with plain water after bathing in a mild hexachlorophene solution. Hexachlorophene may cause skin irritation and toxicity in preterm infants, and thorough rinsing does not prevent potential adverse effects.
D: Avoid cleaning skin. Avoiding cleaning altogether can lead to accumulation of secretions and bacteria, increasing infection risk and hindering skin health maintenance in preterm newborns.
