A patient is taking a monoamine oxidase inhibitor for depression. In planning care for this patient, the nurse knows that a hypertensive crisis may be possible and plans on having what drug on hand as an antidote?
Correct answer
B
Rationale
The correct answer is B: Calcium channel blockers. When a patient taking a monoamine oxidase inhibitor (MAOI) experiences a hypertensive crisis, calcium channel blockers are used as an antidote. Calcium channel blockers help relax blood vessels, reducing blood pressure and counteracting the hypertensive crisis. Meperidine (A) can actually worsen the crisis due to its interaction with MAOIs. Carbamazepine (C) and dextromethorphan (D) do not have a direct antidote effect on MAOI-induced hypertensive crisis.
