A psychiatric-mental health nurse is reviewing a client's medication schedule. The client is prescribed 150 mg of venlafaxine to manage their depression. The pharmacy dispenses venlafaxine 37.5 mg tablets. How many tablets should the nurse administer per dose?
3 tablets
2 tablets
4 tablets
6 tablets
The Correct Answer is C
Choice A reason: Three tablets equal 112.5 mg, which is below the prescribed dose. Administering this amount would underdose the patient, leading to subtherapeutic effects and poor symptom control.
Choice B reason: Two tablets equal 75 mg, which is half the prescribed dose. This would result in significant underdosing and ineffective management of depression.
Choice C reason: Four tablets equal exactly 150 mg, which matches the prescribed dose. This ensures therapeutic effectiveness and safety, making it the correct choice.
Step 1: Ordered dose = 150 mg.
Step 2: Tablet strength = 37.5 mg per tablet.
Step 3: (150 mg ÷ 37.5 mg) = 4 tablets.
Result = 4 tablets.
Choice D reason: Six tablets equal 225 mg, which exceeds the prescribed dose by 75 mg. This would risk overdose and adverse effects such as hypertension, serotonin syndrome, or gastrointestinal disturbances.

Correct Answer is B
Explanation
Choice A reason: Not all cultural practices have historically supported mental health treatment. In many cultures, stigma and alternative explanations for mental illness have shaped perceptions differently.
Choice B reason: Cultural and historical contexts significantly influence how mental health is understood and approached. Historical discrimination, systemic inequities, and cultural traditions shape trust, stigma, and treatment-seeking behaviors. Nurses must recognize these influences to provide equitable care.
Choice C reason: Mental health practices have varied widely across cultures and time periods. Assuming consistency ignores diversity and risks misinterpretation.
Choice D reason: Historical practices were not universally effective and often carried biases. Many systems excluded marginalized groups or perpetuated stigma, making this statement inaccurate.
Correct Answer is D
Explanation
Choice A reason: Standardizing care based on majority culture perpetuates disparities by ignoring minority needs. It enforces cultural dominance rather than inclusivity.
Choice B reason: Prioritizing Western frameworks excludes diverse perspectives and may misinterpret symptoms. This approach reinforces inequities.
Choice C reason: Assuming universality disregards cultural diversity and leads to inappropriate interventions. Mental health beliefs vary widely across cultures.
Choice D reason: Respecting cultural norms ensures care is relevant, acceptable, and effective. It reduces mistrust, increases engagement, and addresses disparities by tailoring interventions to client values.
