Which of the following medications is considered a Galactagogue?
Rationale:
Metoclopramide is considered a Galactagogue. It stimulates dopamine receptors, increasing prolactin levels, which in turn promotes milk production in lactating mothers. This pharmacological effect makes metoclopramide effective for enhancing lactation, especially in cases where milk supply is insufficient, thereby supporting breastfeeding success through hormonal regulation.
A: Metformin primarily treats diabetes by improving insulin sensitivity; it does not influence prolactin secretion or milk production, thus lacking galactagogue properties.
B: Magnesium is a mineral that supports muscle and nerve function but does not have any established role in stimulating lactation or increasing milk supply.
D: Morphine is an opioid analgesic that may suppress prolactin release, potentially reducing milk production, making it unsuitable as a galactagogue.
The neonatal abstinence syndrome has been described as a complex disorder that primarily involves the central and autonomic nervous systems and the gastrointestinal system. The following are the symptoms of neonatal abstinence syndrome, EXCEPT
Rationale:
Excessive weight gain is not a symptom of neonatal abstinence syndrome. NAS typically causes weight loss due to feeding difficulties and increased metabolic demand. Symptoms primarily involve the central and autonomic nervous systems and gastrointestinal distress, leading to irritability, sweating, seizures, and poor feeding, which contribute to weight loss rather than gain in affected newborns.
A: Excessive crying occurs due to central nervous system irritability and withdrawal symptoms, reflecting heightened sensory sensitivity and discomfort in neonates undergoing withdrawal, making it a hallmark sign of NAS.
C: Sweating results from autonomic nervous system overactivity during withdrawal, indicating physiological stress and imbalance common in neonatal abstinence syndrome presentations.
D: Seizures manifest as severe neurological disturbances caused by withdrawal effects on the central nervous system, representing a critical and recognized symptom of NAS.
Which finding is considered normal and expected when the nurse is performing a physical examination on a pregnant woman?
Rationale:
A palpable, full thyroid is considered normal and expected during a physical examination of a pregnant woman. Pregnancy often causes increased vascularity and hormonal changes that lead to thyroid enlargement, making it more easily palpable. This physiological adaptation supports increased metabolic demands, distinguishing it from pathological conditions. Such findings reflect normal pregnancy-related endocrine system changes without indicating disease.
B: Edema in one lower leg suggests localized issues like deep vein thrombosis rather than normal pregnancy changes, which typically cause bilateral, mild swelling due to fluid retention and vascular changes.
C: Significant diffuse enlargement of the thyroid indicates a pathological goiter or thyroid disease, which is not a typical or expected physiological response during pregnancy.
D: Pale mucous membranes of the mouth usually signal anemia or poor perfusion, conditions that require further investigation and are not normal or expected findings in a healthy pregnant woman.
Which Opiate Replacement Therapy is least appropriate during pregnancy?
Rationale:
Buprenorphine and Naloxone is the least appropriate Opiate Replacement Therapy during pregnancy. Buprenorphine combined with naloxone carries potential risks to the fetus because naloxone can precipitate withdrawal symptoms in the mother and fetus, leading to complications. Clinical guidelines recommend avoiding this combination in pregnancy, favoring safer alternatives like methadone or buprenorphine alone for better maternal and fetal outcomes.
A: Methadone Methadone is widely accepted and considered safe during pregnancy, effectively reducing withdrawal symptoms and improving neonatal outcomes, making it an appropriate choice for Opiate Replacement Therapy.
B: Heroin Heroin is not a medically recommended Opiate Replacement Therapy and is harmful during pregnancy, but it is not classified as a therapy option, rather an illicit drug.
C: Buprenorphine Buprenorphine alone is safer during pregnancy than the combination with naloxone, minimizing fetal exposure to withdrawal-inducing agents and improving treatment adherence and outcomes.
The nurse is caring for a patient who is receiving magnesium sulfate for pre-eclampsia. Which assessments will be of the highest priority?
Rationale:
Assessing lung sounds is of the highest priority for a patient receiving magnesium sulfate because respiratory depression is a serious side effect of magnesium toxicity. Early detection of diminished breath sounds or respiratory distress allows prompt intervention, preventing complications such as respiratory failure. Monitoring lung sounds ensures patient safety by identifying potential magnesium-induced respiratory compromise before it worsens.
B: Assessing blood sugar level does not directly relate to magnesium sulfate therapy or pre-eclampsia management, as magnesium sulfate primarily affects neuromuscular and respiratory function rather than glucose metabolism. Blood sugar monitoring is less urgent in this context.
C: Encouraging fluid intake is not a priority because patients with pre-eclampsia often require careful fluid balance management to avoid overload; unrestricted fluids could worsen hypertension or edema.
D: Assessing for pitting edema is important but secondary; edema is a common symptom of pre-eclampsia but does not indicate immediate risk from magnesium sulfate toxicity like respiratory assessment does.
Which of the following can delay lactogenesis?
Rationale:
Stress can delay lactogenesis.
Stress triggers the release of stress hormones like cortisol and adrenaline, which interfere with the hormonal balance essential for milk production. Elevated stress levels inhibit oxytocin release, reducing milk ejection and delaying the establishment of effective lactation in new mothers, impacting both the initiation and continuation of breastfeeding.
A: Constipation Constipation affects bowel movements but has no direct influence on the hormonal mechanisms or physiological processes responsible for initiating milk production and lactogenesis.
B: Decreasing levels of progesterone Progesterone levels drop after delivery to stimulate lactogenesis; decreasing levels actually promote, not delay, the onset of milk production.
D: Apnoea Apnoea involves breathing disruptions unrelated to hormonal or physiological pathways controlling milk synthesis and secretion, making it irrelevant to lactogenesis timing.
During auscultation of fetal heart tones (FHTs), the nurse determines that the heart rate is 136 beats per minute. The nurse's next action should be to:
Rationale:
The nurse should document the results, which are within normal range. A fetal heart rate of 136 beats per minute falls within the typical range of 110 to 160 bpm, indicating no immediate concerns. Recording this normal finding ensures accurate medical records and ongoing monitoring without unnecessary interventions or delays in care. This confirms fetal well-being during assessment.
B: Take the maternal pulse to verify these findings as the uterine souffle assumes maternal pulse is confused with fetal heart tones, but 136 bpm aligns with fetal norms, reducing the likelihood of misinterpretation.
C: Have the patient change positions and count the FHTs again misdirects focus since the initial rate is normal, and repositioning is unnecessary without signs of abnormality or irregularity.
D: Immediately notify the physician for possible fetal distress overreacts to a heart rate well within accepted parameters, causing unwarranted alarm and disrupting standard monitoring protocols.
A woman has been unable to conceive for many months and will soon begin treatment with clomiphene (Clomid). What health education should the nurse provide to this patient?
Rationale:
Take her basal temperature between 5 to 10 days after taking Clomid. Measuring basal body temperature helps identify ovulation, which typically occurs after Clomid stimulates follicle development. This timing guides the patient to recognize her fertile window, increasing chances of conception. Monitoring temperature daily offers valuable insight into treatment effectiveness and aids in planning intercourse during peak fertility.
A: Avoid drinking alcohol while taking Clomid. Although general health advice discourages alcohol, no specific interaction between Clomid and alcohol necessitates strict avoidance during treatment.
B: Perform daily OTC pregnancy tests beginning the day after taking Clomid. Pregnancy tests are ineffective immediately after Clomid; waiting until after a missed period is essential for accurate results.
D: Report any numbness or tingling in her hands or lips to her care provider. These neurological symptoms are rare and not common side effects of Clomid, making this advice less relevant for routine education.
The nurse is caring for a woman with a history of a previous preterm birth. Based on current knowledge related to cervical incompetency, which should the nurse do?
Rationale:
The nurse should be prepared to discuss the action and side effects of progesterone. Progesterone is commonly used to help reduce the risk of preterm birth in women with a history of cervical incompetency by supporting uterine quiescence and decreasing contractions. Educating the patient about its benefits and potential side effects ensures informed consent and adherence to the prescribed therapy.
A: Prepare the woman for an abdominal ultrasound focuses on fetal imaging, not specifically on assessing or managing cervical incompetency, which requires different diagnostic or therapeutic approaches.
B: Place the patient on her left side to increase perfusion to the fetus addresses general fetal oxygenation but does not directly relate to cervical insufficiency management or prevention of preterm labor.
D: Monitor the patient's blood pressure closely is important for hypertensive disorders but does not target cervical incompetency or its prevention strategies specifically.
A woman is at 42 weeks of gestation. Which of the following medications will be administered to promote cervical ripening?
Rationale:
Dinoprostone (Cervidil) will be administered to promote cervical ripening. Dinoprostone is a synthetic prostaglandin E2 analog used to soften and dilate the cervix, facilitating labor induction, especially in post-term pregnancies like 42 weeks. It effectively prepares the cervix by breaking down collagen and increasing water content, promoting readiness for labor and reducing the need for cesarean delivery.
A: Calcium gluconate Calcium gluconate is primarily used to treat hypocalcemia and does not influence cervical ripening or labor induction mechanisms, making it irrelevant for promoting cervical changes at 42 weeks gestation.
B: Magnesium sulfate Magnesium sulfate serves as a tocolytic to prevent preterm labor and protect against seizures in preeclampsia; it does not facilitate cervical softening or dilation necessary for labor initiation.
C: Terbutaline (Brethine) Terbutaline is a beta-agonist used to inhibit uterine contractions, delaying labor rather than promoting cervical ripening, thus unsuitable for inducing labor or preparing the cervix at term or post-term.
A pregnant woman states that she has been constipated since becoming pregnant. Which medication is most appropriate for preventing constipation related to pregnancy?
Rationale:
Metamucil is the most appropriate medication for preventing constipation related to pregnancy.
Metamucil, a bulk-forming fiber supplement, is safe during pregnancy and works by increasing stool bulk and water content, promoting natural bowel movements without causing dependency or electrolyte imbalance. It gently alleviates constipation without irritating the gastrointestinal tract, making it suitable for long-term use in pregnant women who often experience slowed gut motility.
B: Mineral oil can interfere with the absorption of fat-soluble vitamins, which are crucial during pregnancy, and may cause lipid pneumonia if aspirated, making it unsuitable for routine constipation treatment in pregnant women.
C: Saline cathartics cause rapid bowel evacuation by drawing water into the intestines but may lead to electrolyte disturbances and dehydration, posing risks to both mother and fetus during pregnancy.
D: Stimulant cathartics induce strong intestinal contractions and may cause cramping or dependence; their aggressive mechanism is generally avoided in pregnancy to prevent uterine stimulation or discomfort.
The prevalence of smoking in pregnancy is lowest in which of the subgroups?
Rationale:
Women in major cities have the lowest prevalence of smoking in pregnancy. Urban areas typically offer better access to healthcare, smoking cessation programs, and health education, contributing to reduced smoking rates among pregnant women. Socioeconomic factors and community support in cities also play significant roles, making this subgroup less likely to engage in smoking during pregnancy compared to others.
A: Women of lower socioeconomic status experience higher smoking rates due to financial stress, limited healthcare access, and increased exposure to smoking environments, resulting in elevated prevalence during pregnancy.
B: Women of Aboriginal or Torres Strait Islander backgrounds face cultural, social, and economic challenges that contribute to higher smoking rates during pregnancy compared to other groups.
D: Women with psychiatric disorders often have increased smoking prevalence due to stress coping mechanisms and barriers to quitting, leading to higher rates during pregnancy.
During an assessment of a client at 32 weeks gestation with a history of congenital ventral septal defect, a nurse notes that the client is experiencing a nonproductive cough on minimal exertion. The nurse knows that this assessment finding may indicate which of the following?
Rationale:
Pulmonary edema may be indicated by a nonproductive cough on minimal exertion in a client with a history of congenital ventricular septal defect at 32 weeks gestation.
Pulmonary edema occurs due to fluid accumulation in the lungs, often from heart complications like ventricular septal defects, leading to respiratory symptoms such as a persistent, nonproductive cough and exertional dyspnea. This aligns with the client's presentation and cardiac history.
A: Orthopnea involves difficulty breathing when lying flat, not specifically a cough triggered by minimal exertion, making it less applicable in this scenario.
C: Anemia typically causes fatigue and pallor but does not directly produce a nonproductive cough related to exertion in this clinical context.
D: Decreased blood volume usually results in hypotension and dizziness, but it does not explain a nonproductive cough or respiratory symptoms linked to cardiac issues.
Which of the following antidepressants would be considered first line treatment for perinatal depression (PND) that occurs during a pregnancy?
Rationale:
Sertraline is considered a first-line treatment for perinatal depression during pregnancy. Sertraline has an established safety profile with lower risk of teratogenicity and neonatal complications compared to other antidepressants, making it preferable. Its extensive research supports efficacy and maternal-fetal safety, positioning it as the preferred selective serotonin reuptake inhibitor (SSRI) for managing depression in pregnant patients.
A: Paroxetine poses a higher risk of cardiac malformations and neonatal adverse effects, limiting its use during pregnancy.
C: Clomipramine, a tricyclic antidepressant, carries increased side effects and less robust safety evidence in pregnancy, reducing its suitability.
D: Venlafaxine, a serotonin-norepinephrine reuptake inhibitor (SNRI), lacks sufficient data to confirm safety as a first-line choice in pregnancy.
How should the nurse respond to a 30-year-old woman asking if she should continue to have a Papanicolaou test every year?
Rationale:
You can now start getting screened with a Papanicolaou test every 3 years. Current guidelines recommend that women aged 21 to 29 have a Pap test every three years if results are normal, reducing unnecessary procedures while maintaining effective cervical cancer screening. Annual screening is no longer necessary unless other risk factors are present.
B: Screening should continue annually. Annual screening is outdated and increases the risk of overdiagnosis and overtreatment without significantly improving cancer detection in low-risk women aged 30 and above.
C: Screening is no longer necessary after age 30. Cervical cancer screening remains essential after 30, though less frequent, to detect precancerous changes early and prevent progression.
D: Screening should occur every 5 years. Five-year intervals apply only when Pap testing is combined with HPV testing, not for Pap tests alone, which require a three-year interval.
The neonatal abstinence syndrome has been described as a complex disorder that primarily involves the central and autonomic nervous systems and the gastrointestinal system. The following are the symptoms of neonatal abstinence syndrome, EXCEPT
Rationale:
Neonatal abstinence syndrome does not include excessive weight gain as a symptom.
Excessive weight gain contradicts the typical presentation of NAS, where infants usually experience weight loss or poor weight gain due to feeding difficulties and increased metabolic demand from withdrawal symptoms. This option stands out because NAS primarily causes weight loss rather than weight gain, aligning poorly with known clinical manifestations.
A: Excessive crying manifests from heightened irritability and central nervous system hyperactivity, making it a common and documented symptom of neonatal abstinence syndrome.
C: Sweating results from autonomic nervous system dysregulation, a hallmark feature in neonatal abstinence syndrome’s withdrawal symptomatology.
D: Seizures reflect severe central nervous system involvement and are recognized complications in the clinical spectrum of neonatal abstinence syndrome.
A nurse has just completed an assessment on a client with mild pre-eclampsia. Which data indicate that her pre-eclampsia is worsening?
Rationale:
A blood pressure of 155/95 indicates that her pre-eclampsia is worsening. Elevated blood pressure beyond mild pre-eclampsia thresholds signals progression toward severe pre-eclampsia, increasing risks for complications. Monitoring blood pressure is critical for assessing severity, guiding interventions, and preventing organ damage or eclampsia, making this value a key indicator of deterioration in the client's condition.
B: Urinary output greater than 30 mL/hr reflects adequate kidney perfusion and function, suggesting no worsening renal impairment typically seen in severe pre-eclampsia, thus not indicating progression of the condition.
C: Deep tendon reflexes +2 represent normal neurological status, lacking hyperreflexia or clonus signs that would indicate worsening pre-eclampsia or impending seizures.
D: Blurred vision is a symptom of worsening pre-eclampsia, but the correct answer focuses on objective vital data; blurred vision alone does not definitively indicate progression absent other clinical signs.
When the nurse is assessing the deep tendon reflexes (DTRs) on a woman who is 32 weeks pregnant, which of these would be considered a normal finding on a 0 to 4+ scale?
Rationale:
A 2+ rating on the 0 to 4+ deep tendon reflex scale represents a normal, average response. This finding indicates appropriate neurological function without exaggeration or diminution of reflex activity. During pregnancy, maintaining normal reflexes like 2+ is expected unless pathological conditions such as preeclampsia cause hyperreflexia or other abnormalities in reflex responses.
A: Absent DTRs indicates neurological impairment or peripheral nerve damage, which is not typical in a healthy pregnant woman and signals abnormal reflex activity.
C: 4+ signifies hyperactive reflexes, often linked to neurological disorders or complications like preeclampsia, making it an abnormal finding during pregnancy.
D: Brisk reflexes with clonus demonstrate exaggerated neurological responses, often associated with central nervous system pathology or pregnancy complications, not a normal reflex state.
Which of these agents have the highest teratogenic potential?
Rationale:
Phenytoin has the highest teratogenic potential among the listed agents. Phenytoin is a well-documented teratogen linked to fetal hydantoin syndrome, causing congenital malformations such as craniofacial abnormalities and heart defects. Its mechanism involves interference with folate metabolism and oxidative stress, significantly increasing the risk of birth defects compared to the other options, which have minimal or no teratogenic effects.
A: Omeprazole Omeprazole shows minimal teratogenic risk, with studies indicating no significant increase in congenital malformations. Its safety profile in pregnancy is generally considered acceptable, unlike known teratogens.
C: Paracetamol Paracetamol is widely regarded as safe during pregnancy with no substantial evidence of teratogenicity, making it a preferred analgesic and antipyretic for pregnant women.
D: Folic Acid Folic acid is protective rather than harmful, preventing neural tube defects and promoting fetal development, thus it does not possess teratogenic potential but rather reduces risk of birth defects.
Why is the alphabetical system of pregnancy drug categories no longer used in the AMH?
Rationale:
The alphabetical system of pregnancy drug categories is no longer used in the AMH because it does not indicate which stage of development is affected by the drug. This system lacked specificity regarding developmental timing, which is crucial for assessing teratogenic risks. Without this detail, it cannot guide clinicians accurately on potential effects during different pregnancy stages, limiting its clinical utility and safety assessment precision.
A: It does not differentiate safety profiles between pregnancy and lactation, but this limitation alone is not the primary reason for discontinuing the system in the AMH.
B: The categorisation system was based on limited data and animal studies; however, the main issue relates to developmental stage specificity, not just data origin.
C: The categorisation system was generalised without considering population characteristics, yet this generalisation is secondary to the lack of developmental timing information in its classification.
The labor and delivery nurse reviews a client's prenatal records and notes that the client had a positive GBS culture at 27 weeks gestation. Based on current guidelines, what is the recommended plan?
Rationale:
Prepare to administer penicillin prophylactically. Current guidelines recommend intrapartum antibiotic prophylaxis for clients with a positive GBS culture during pregnancy to prevent neonatal infection, regardless of the timing of the culture, ensuring adequate protection during labor and delivery.
A: Send a GBS to the laboratory immediately delays necessary treatment since the positive culture is already documented and timely antibiotic administration is prioritized during labor.
C: Determine if a follow-up culture was done at 38 weeks gestation overlooks that treatment depends on the initial positive result, not just repeat cultures, which may not alter management.
D: Determine if the patient received antibiotics for the positive strep ignores the urgency of administering antibiotics during labor rather than relying on prior treatments given earlier in pregnancy.
During auscultation of fetal heart tones (FHTs), the nurse determines that the heart rate is 136 beats per minute. The nurse's next action should be to:
Rationale:
The nurse should document the results, which are within normal range. A fetal heart rate of 136 beats per minute falls within the typical range of 110 to 160 bpm, indicating a healthy fetal status. Therefore, no immediate intervention is necessary, and proper documentation ensures accurate records for ongoing monitoring and care planning.
B: Take the maternal pulse to verify these findings as the uterine souffle misinterprets the fetal heart rate; the rate of 136 bpm is clearly fetal, not maternal, so this step is unnecessary.
C: Have the patient change positions and count the FHTs again is redundant since the initial rate is normal and stable, making repositioning unwarranted.
D: Immediately notify the physician for possible fetal distress is premature because a heart rate of 136 bpm is normal and does not suggest fetal distress requiring urgent notification.
A client who is 30 weeks pregnant comes into the labor and delivery unit complaining of having a gush of fluid come from her vagina. Which complication is this client at risk for?
Rationale:
A client who experiences a gush of fluid from the vagina at 30 weeks pregnant is at risk for fluid volume deficit. This occurs because premature rupture of membranes results in loss of amniotic fluid, leading to dehydration and potential electrolyte imbalances. Monitoring and fluid replacement are crucial to prevent complications related to decreased circulating volume and maintain maternal-fetal well-being.
A: Infection Premature rupture of membranes increases susceptibility to ascending infections as the protective barrier is compromised, but infection is a secondary risk, not the immediate concern following fluid loss.
C: Hypotension Fluid loss may contribute to hypovolemia, but hypotension is not the primary risk; it is a potential consequence rather than the direct complication described by the gushing fluid.
D: Decreased urinary output Loss of amniotic fluid does not directly cause decreased urinary output; in fact, fluid deficit might initially concentrate urine but does not primarily reduce urine production.
A nurse is caring for a client who is 32 weeks gestation who comes to the emergency department for painful bleeding. Which is the priority nursing assessment?
Rationale:
Assess for hemorrhage.
Assessing for hemorrhage is crucial because painful bleeding at 32 weeks gestation can indicate placental abruption or other serious complications that threaten both maternal and fetal health. Early identification of excessive bleeding allows prompt intervention to prevent hypovolemia, shock, and fetal distress, making this the highest priority to ensure safety and stabilize the client’s condition.
A: Monitor for contractions Contractions may indicate labor onset but are secondary to identifying life-threatening bleeding. Prioritizing contractions overlooks immediate risks from hemorrhage requiring urgent assessment and management to prevent severe complications.
B: Assess pain level Pain evaluation is important but not the most urgent. Pain may reflect bleeding severity, but direct hemorrhage assessment provides critical information about bleeding volume and maternal-fetal risk, guiding immediate clinical responses.
D: Provide emotional support Emotional support is valuable but not the immediate priority during acute bleeding. Stabilizing physical status through hemorrhage assessment takes precedence, as untreated bleeding presents a direct threat to life that must be addressed first.
Which of the following medications has the least amount of evidence for its safety when used during pregnancy?
Rationale:
Saxagliptin (category B3) has the least amount of evidence for its safety during pregnancy. Category B3 indicates limited data and potential fetal harm in animal studies without sufficient human studies. This contrasts with other options having more established safety profiles, making saxagliptin the least supported choice regarding prenatal safety evidence.
A: Fluticasone propionate (Flixotide, category B3) shares the same category but has more extensive clinical use and data supporting its relative safety compared to saxagliptin.
B: Metformin (category C) has documented use and studies in pregnancy, providing more safety information despite some risks.
D: Budesonide (category A) offers the highest safety assurance with well-established evidence confirming its safe profile during pregnancy.
A patient is receiving oxytocin (Pitocin). Which of the following is a maternal adverse effect of Pitocin?
Rationale:
Oxytocin (Pitocin) can cause hypertension as a maternal adverse effect. Oxytocin stimulates uterine contractions and vasopressin receptors, potentially raising blood pressure. This hypertensive response results from vasoconstriction and fluid retention, which increase vascular resistance and blood volume. Monitoring maternal blood pressure during administration is crucial to prevent complications such as preeclampsia or cardiac strain, ensuring patient safety throughout labor induction or augmentation.
A: Acute confusion Oxytocin does not typically affect cognitive function or cause neurological symptoms like acute confusion; such symptoms are unrelated to its pharmacological effects on uterine and vascular tissues.
C: Edema Edema is not a primary adverse effect of oxytocin; fluid retention occurs but does not commonly manifest as peripheral or generalized swelling in patients receiving Pitocin.
D: Inverted T wave Cardiac electrocardiogram changes like inverted T waves are not associated with oxytocin administration; this sign usually indicates ischemic heart disease, unrelated to oxytocin’s mechanism or side effects.
A woman in labor is being treated with magnesium sulfate intravenously and is beginning to show signs and symptoms of hypermagnesemia. The infusion has been discontinued, and the nurse should anticipate administration of what drug?
Rationale:
Calcium gluconate should be administered to counteract hypermagnesemia caused by magnesium sulfate toxicity.
Calcium gluconate acts as a magnesium antagonist by stabilizing cardiac membranes and reversing neuromuscular blockade. It rapidly alleviates symptoms such as hypotension, respiratory depression, and muscle weakness associated with elevated magnesium levels, making it the immediate treatment choice after stopping magnesium sulfate infusion.
A: Metoprolol (Lopressor) Beta-blockers reduce heart rate but do not reverse magnesium toxicity or stabilize cardiac membranes, thus offering no direct benefit in hypermagnesemia management.
C: Potassium chloride Potassium supplementation does not address elevated magnesium levels and may worsen electrolyte imbalances without mitigating the toxic effects of magnesium sulfate.
D: Furosemide (Lasix) Although it promotes magnesium excretion, furosemide acts slower and is not the immediate antidote required to quickly reverse hypermagnesemia symptoms.
The nurse is caring for a client with a suspected hydatidiform mole. Based on the diagnosis, what does the nurse anticipate? Select all that apply.
Rationale:
The nurse anticipates strong fetal heart tones based on the diagnosis of a hydatidiform mole. This condition involves abnormal trophoblastic proliferation, often leading to absence or abnormal development of the embryo, making the presence of strong fetal heart tones unexpected in typical presentations of a molar pregnancy.
A: Dark brown vaginal bleeding is typical in molar pregnancy but it is not the primary expected finding related to the diagnosis. This option reflects symptomatology, not diagnostic anticipation.
C: Fundal height larger than expected usually occurs due to uterine enlargement with molar tissue but does not directly correlate with the nurse’s primary diagnostic anticipation.
D: Elevated blood pressure can develop with molar pregnancies but it is a secondary complication, not an immediate diagnostic expectation for the nurse in suspected cases.
The nurse is caring for a client with severe hyperemesis gravidarum. She is 10 weeks gestation and has a 10% weight loss. The client is being admitted for fluid and electrolyte replacement. The nurse is aware it is important to check which deficiency that puts the client at risk for Wernicke's encephalopathy?
Rationale:
Thiamine deficiency is the key risk factor for Wernicke's encephalopathy in clients with severe hyperemesis gravidarum.
Thiamine (vitamin B1) is essential for brain metabolism, and prolonged vomiting causes depletion. Without adequate replacement, neurological complications like Wernicke's encephalopathy can develop, making thiamine assessment and supplementation critical during treatment for severe hyperemesis gravidarum.
A: Folic acid primarily prevents neural tube defects, not neurological damage from thiamine deficiency.
B: Vitamin D deficiency affects bone metabolism, unrelated to Wernicke's encephalopathy risk.
D: Glucose intake without thiamine can worsen Wernicke’s encephalopathy but glucose itself is not the deficiency causing it.
How should the nurse respond if asked if there are vaccines available to prevent STIs?
Rationale:
A vaccine has been approved to prevent the human papillomavirus. This option accurately reflects the current medical advancements, highlighting that HPV vaccination is a significant preventive measure against certain sexually transmitted infections, demonstrating the importance of vaccines in public health.
B: There are no vaccines available for STIs. This statement overlooks the existence of effective vaccines, such as those for HPV, which protect against specific sexually transmitted infections and promote health awareness.
C: Vaccines are available for hepatitis A, hepatitis B, and HPV. While partially true, this response lacks specificity and fails to emphasize that the question pertains specifically to the HPV vaccine as a notable example.
D: Vaccines are under development for HIV and HSV. Although this indicates ongoing research, it does not address existing vaccines currently available for STIs, misrepresenting the current vaccination landscape.
