Rationale: The correct answer is A. Clients should not stop taking sertraline abruptly once they feel better without consulting their healthcare provider. It is important to complete the full course of treatment as prescribed to prevent a relapse of symptoms. Stopping the medication suddenly can lead to withdrawal symptoms and may worsen the condition.

Rationale: Carbidopa-levodopa increases the amount of levodopa to the CNS, providing more dopamine to the brain. Increased dopamine levels help alleviate Parkinson's symptoms such as tremors, involuntary movements, and gait abnormalities.

Correct Answer: C

Rationale: Erythropoietin is prescribed to stimulate the production of red blood cells. Clients undergoing hemodialysis often develop anemia due to end-stage renal disease. Erythropoietin helps in correcting this anemia by stimulating red blood cell production. It is not used to prevent infections associated with dialysis, deep vein thrombosis, or to balance phosphorus levels in the body.

Correct Answer: A

Rationale: When a client with chronic kidney disease is prescribed sevelamer carbonate, the nurse should monitor for hypercalcemia as a potential side effect. Sevelamer carbonate can bind to dietary calcium and impair its absorption, potentially leading to elevated calcium levels in the blood. Monitoring calcium levels is crucial to detect and manage hypercalcemia promptly.

Correct Answer: A

Rationale: Nitroglycerin sublingual tablets are sensitive to heat and moisture, so they should be stored in a cool, dry place to maintain their efficacy.

Choice C is incorrect because sublingual tablets should be placed under the tongue to dissolve, not swallowed. Choice D is incorrect because sublingual tablets should not be chewed; they are meant to be absorbed through the tissues under the tongue.
