Correct Answer is A

Explanation

Choice A rationale

Prazosin, an alpha-blocker, is often started at the lowest dose and taken at night to minimize the risk of orthostatic hypotension, a sudden drop in blood pressure upon standing.

Choice B rationale

Starting prazosin at the highest dose is not recommended due to the risk of severe orthostatic hypotension, which can lead to dizziness and fainting.

Choice C rationale

It is important to monitor blood pressure with the first dose of prazosin to assess the patient's response and avoid significant drops in blood pressure.

Choice D rationale

Prazosin may take several weeks to achieve full therapeutic effect. It does not control hypertension within a week.

A. This medication is also used to treat malignant hyperthermia. B. This medication is used to treat muscle spasticity. C. This medication can be used for pain management. D. This medication helps in reducing muscle stiffness.

Correct Answer is A

Explanation

Choice A rationale

Dantrolene is used to treat malignant hyperthermia, a rare life-threatening condition usually triggered by certain anesthetics or muscle relaxants.

Choice B rationale

Although dantrolene is used to treat muscle spasticity, the indication in this question is specifically about malignant hyperthermia, making this choice not the most appropriate.

Choice C rationale

Dantrolene is not typically used for general pain management. Its primary use is in malignant hyperthermia and severe spasticity.

Choice D rationale

While reducing muscle stiffness can be a result of its spasticity treatment, malignant hyperthermia is a more specific and critical use of dantrolene.
