A nurse is discussing antidepressant therapy with a provider. Which of the following clients should the nurse identify as being a candidate for antidepressant therapy?
A client who has decreased serotonin levels.
A client who has decreased cortisol levels.
A client who has elevated dopamine levels.
A client who has elevated thyroid levels.
The Correct Answer is A
Choice A reason: Decreased serotonin levels are linked to depression, as serotonin regulates mood in the brain’s limbic system. Antidepressants like SSRIs increase serotonin, alleviating low mood and anhedonia, making this client a prime candidate for therapy to address neurochemical imbalances in depression.
Choice B reason: Decreased cortisol is not directly tied to depression requiring antidepressants. Cortisol dysregulation may occur in stress disorders, but antidepressants target serotonin or norepinephrine, not adrenal function, making this client less suitable for antidepressant therapy based on this imbalance.
Choice C reason: Elevated dopamine is linked to schizophrenia or mania, not depression. Antidepressants target serotonin or norepinephrine, not dopamine. This client may need antipsychotics or mood stabilizers, not antidepressants, as dopamine excess does not indicate depressive pathology requiring such therapy.
Choice D reason: Elevated thyroid levels suggest hyperthyroidism, mimicking anxiety, not depression. Antidepressants are not indicated, as treatment targets thyroid function. Depression may coexist, but thyroid correction is prioritized, making this client unsuitable for primary antidepressant therapy based on this finding.

Correct Answer is ["A","B","C","D","E"]
Explanation
Choice A reason: Anuria, minimal or no urine output, is expected in end-stage kidney disease (ESKD) due to nephron loss, reducing glomerular filtration rate. This causes fluid and toxin buildup, requiring dialysis to manage fluid balance and prevent complications like uremia in ESKD clients.
Choice B reason: Edema results from impaired sodium and water excretion in ESKD, causing fluid overload. Reduced filtration leads to volume retention, manifesting as peripheral or pulmonary edema, increasing cardiovascular strain and necessitating diuretics or dialysis to control fluid status effectively.
Choice C reason: Hyperkalemia occurs in ESKD, as failing kidneys cannot excrete potassium, elevating serum levels. This risks cardiac arrhythmias due to disrupted membrane potentials. Dietary restrictions or dialysis are needed to manage potassium, preventing life-threatening complications in end-stage renal failure.
Choice D reason: Hypocalcemia in ESKD stems from impaired vitamin D activation and phosphate retention, binding calcium. This disrupts bone mineralization and neuromuscular function, causing tetany or fractures. Calcium supplementation and dialysis correct this imbalance, addressing renal failure’s metabolic consequences.
Choice E reason: Metabolic acidosis in ESKD results from impaired hydrogen ion excretion and bicarbonate reabsorption. This lowers blood pH, causing fatigue and bone demineralization. Dialysis or bicarbonate therapy corrects acid-base imbalances, addressing the kidneys’ failure to maintain homeostasis in end-stage disease.
Correct Answer is B
Explanation
Choice A reason: Attaching restraints to movable side rails is unsafe, as rail movement can cause injury or loosen restraints. They should be secured to the bed frame, a fixed structure, so this guideline is incorrect and dangerous for restraint protocols.
Choice B reason: Documenting the client’s condition every 15 minutes ensures frequent monitoring for safety, circulation, and skin integrity, per CMS and Joint Commission standards. This prevents complications and supports timely restraint removal, making it the correct guideline.
Choice C reason: Requesting PRN restraint prescriptions is inappropriate, as restraints require specific, time-limited orders based on immediate need. PRN orders lack oversight and risk misuse, so this guideline is incorrect and non-compliant with regulations.
Choice D reason: Applying restraints over clothing can cause discomfort or skin irritation, as direct skin contact with padding is preferred for safety. This guideline is incorrect, as proper application minimizes harm, making it inappropriate for protocols.
