A nurse is providing teaching to a client who is receiving intermittent parenteral potassium chloride. Which of the following conditions should the nurse recognize as an indication for this medication?
Seizures
Kidney transplant
Arrythmia
Endocarditis
The Correct Answer is C
A. Seizures: Seizures are not an indication for potassium chloride administration. While severe electrolyte imbalances can contribute to seizures, potassium replacement is specifically indicated for low potassium levels rather than seizure management.
B. Kidney transplant: Kidney transplant patients may require careful electrolyte monitoring, but potassium chloride is not automatically indicated unless hypokalemia is present. Administration is based on lab values, not transplant status alone.
C. Arrhythmia: Hypokalemia can cause cardiac arrhythmias due to altered myocardial excitability. Potassium chloride is administered to correct low potassium levels and help prevent or treat arrhythmias.
D. Endocarditis: Endocarditis is an infection of the heart valves and is treated with antibiotics. Potassium chloride does not play a role in treating bacterial infections or inflammation of the heart.

Correct Answer is D
Explanation
A. Liver toxicity: Prednisone is metabolized by the liver but is not commonly associated with hepatotoxicity. Liver function monitoring is not a primary concern for long-term prednisone therapy.
B. Hemolytic anemia: Prednisone does not typically cause hemolytic anemia. Its primary hematologic effects involve immunosuppression rather than direct destruction of red blood cells.
C. Hypoglycemia: Prednisone can increase blood glucose levels by promoting gluconeogenesis and reducing peripheral glucose uptake, which may lead to hyperglycemia rather than hypoglycemia.
D. Bone loss: Long-term use of prednisone decreases calcium absorption and bone formation, increasing the risk of osteoporosis and fractures. Monitoring bone density and implementing preventive measures is essential for clients on chronic corticosteroid therapy.
Correct Answer is D
Explanation
A. Dexamethasone: Dexamethasone is a corticosteroid used to promote fetal lung maturity in preterm labor or to reduce inflammation. It does not counteract magnesium sulfate toxicity and is not indicated for respiratory depression or absent reflexes.
B. Methylergonovine: Methylergonovine is a uterotonic used to treat postpartum hemorrhage by stimulating uterine contractions. It does not reverse magnesium sulfate toxicity or address respiratory depression.
C. Naloxone: Naloxone is an opioid antagonist used to reverse opioid-induced respiratory depression. Since the client’s symptoms are due to magnesium sulfate toxicity, naloxone would not be effective.
D. Calcium gluconate: Calcium gluconate is the antidote for magnesium sulfate toxicity. It works by antagonizing the effects of magnesium on neuromuscular and cardiac function, helping to restore normal reflexes and improve respiratory function.
