A patient with depression is prescribed sertraline 50 mg once daily. If the medication is administered for 14 days, what is the total dosage in milligrams?
700 mg.
500 mg.
750 mg.
600 mg.
The Correct Answer is A
Choice A reason: The patient is prescribed 50 mg of sertraline daily for 14 days. The total dosage is calculated as 50 mg/day × 14 days = 700 mg, making this the correct answer.
Choice B reason: A total of 500 mg would imply a daily dose of approximately 35.7 mg (500 ÷ 14), which does not match the prescribed 50 mg daily dose. This is incorrect.
Choice C reason: A total of 750 mg would imply a daily dose of approximately 53.6 mg (750 ÷ 14), which exceeds the prescribed 50 mg daily dose. This is incorrect.
Choice D reason: A total of 600 mg would imply a daily dose of approximately 42.9 mg (600 ÷ 14), which is less than the prescribed 50 mg daily dose. This is incorrect.

Correct Answer is B
Explanation
Choice A reason: Risperidone more commonly causes orthostatic hypotension rather than hypertension, so this is misleading information.
Choice B reason: Constipation is a frequent adverse effect due to anticholinergic action. Increasing fluid and fiber is an appropriate teaching strategy to manage this side effect.
Choice C reason: Weekly blood tests are not required for risperidone; such monitoring is typically associated with clozapine due to the risk of agranulocytosis.
Choice D reason: Risperidone is more likely to cause weight gain and metabolic syndrome, not weight loss, making this response inaccurate.
Correct Answer is C
Explanation
Choice A reason:Cottage cheese is a low-tyramine food and generally safe for patients taking monoamine oxidase inhibitors (MAOIs) like phenelzine. It does not pose a significant risk of causing a hypertensive crisis, which is a concern with MAOIs due to their interaction with tyramine-rich foods.
Choice B reason:Shellfish is not typically high in tyramine, the compound that can cause dangerous interactions with MAOIs. While food safety (e.g., avoiding spoiled shellfish) is important, shellfish does not need to be avoided specifically due to phenelzine use.
Choice C reason:Salami, a cured meat, is high in tyramine, which can interact with MAOIs like phenelzine. This interaction can lead to a hypertensive crisis, characterized by dangerously high blood pressure, headaches, and other serious symptoms. Patients on MAOIs must avoid tyramine-rich foods like aged meats, cheeses, and fermented products.
Choice D reason:Frozen peas are not high in tyramine and do not pose a risk when taken with MAOIs. They are generally safe for consumption and do not require dietary restrictions for patients on phenelzine.
