A nurse is caring for patients receiving clozapine, lithium, fluoxetine, and venlafaxine. Which patient should the nurse be most alert for problems associated with fluid and electrolyte imbalance?
Clozapine
Lithium
Fluoxetine
Venlafaxine
The Correct Answer is B
Choice A reason: Clozapine, an antipsychotic, primarily causes agranulocytosis and metabolic issues, not fluid or electrolyte imbalances. Its effects on the central nervous system and bone marrow do not directly disrupt electrolyte homeostasis, making this choice incorrect for this concern.
Choice B reason: Lithium, a mood stabilizer, affects renal function, impairing sodium and water reabsorption, leading to potential hyponatremia or dehydration. This requires close monitoring of electrolytes, as imbalances can cause toxicity, making this the correct choice for heightened alertness.
Choice C reason: Fluoxetine, an SSRI, primarily affects serotonin levels, with minimal impact on fluid or electrolyte balance. Side effects like nausea do not significantly disrupt electrolytes, making this choice incorrect compared to lithium’s known renal effects.
Choice D reason: Venlafaxine, an SNRI, influences serotonin and norepinephrine but does not significantly affect fluid or electrolyte balance. Its side effects, like hypertension, are unrelated to electrolyte homeostasis, making this choice incorrect for this specific concern.

Correct Answer is A
Explanation
Choice A reason: Basic-level nurses, such as LPNs or RNs, can teach coping skills, a standard intervention within their scope. This involves education on stress management, aligning with psychiatric nursing roles to support patient and family well-being, making this the correct choice.
Choice B reason: Treating major depressive disorder requires advanced skills, like prescribing or managing complex therapies, which is beyond a basic-level nurse’s scope. This is typically reserved for advanced practice nurses or physicians, making this choice incorrect.
Choice C reason: Prescribing antidepressants is restricted to advanced practice nurses or physicians, not basic-level nurses. This task involves medical decision-making outside the scope of RNs or LPNs, making it unsafe and inappropriate, thus incorrect.
Choice D reason: Assessing suicide risk requires advanced clinical judgment, often reserved for advanced practice nurses or psychiatrists. While basic-level nurses can observe and report, formal assessment exceeds their scope, making this choice incorrect for their role.
Correct Answer is C
Explanation
Choice A reason: Autonomy involves respecting a patient’s right to make decisions. While relevant in mental health, the scenario focuses on differing treatments for similar conditions, not patient choice, making autonomy less directly applicable than the principle of fair treatment across patients.
Choice B reason: Beneficence emphasizes promoting patient well-being. Both restraints and supervision aim to prevent harm, fulfilling beneficence, but the concern is about unequal treatment, not the intent to benefit, making this principle less relevant than justice.
Choice C reason: Justice involves fair and equitable treatment for all patients. Using restraints for one self-mutilating patient and supervision for another raises concerns about consistency and fairness in care, directly aligning with the ethical principle of justice, making this the correct choice.
Choice D reason: Nonmaleficence focuses on avoiding harm. Both interventions aim to prevent self-mutilation, fulfilling this principle, but the ethical issue is about equitable application, not harm avoidance, making justice the more relevant principle in this scenario.
