A 25-year-old male presents for ECT (electroconvulsive shock therapy) at a free-standing facility. He has a life- threatening depressive illness that has not responded adequately to medication, however he is still taking tranylcypramine (Parnate). You should

**Core Concept**
Tranylcypromine (Parnate) is a non-selective monoamine oxidase inhibitor (MAOI) that elevates serotonin, norepinephrine, and dopamine levels by irreversible inhibition of monoamine oxidase (MAO). This mechanism poses a risk during ECT due to potential hypertensive crises.

**Why the Correct Answer is Right**
The correct answer is related to the interaction between MAOIs and ECT. MAOIs can cause unpredictable and severe hypertension when combined with ECT due to the release of catecholamines during the procedure. This is because MAOIs block the breakdown of catecholamines, leading to an accumulation and subsequent release during the ECT-induced seizure, causing a hypertensive crisis.

**Why Each Wrong Option is Incorrect**
**Option A:** Discontinuing the MAOI for 2 weeks before ECT is not sufficient to prevent hypertensive crises during the procedure. MAOIs have a prolonged half-life and can cause persistent inhibition of MAO for weeks after discontinuation.
**Option B:** Monitoring blood pressure during ECT is crucial but not sufficient to prevent hypertensive crises. The risk of severe hypertension is unpredictable and can occur suddenly, making monitoring insufficient to prevent adverse outcomes.
**Option B is not present to be evaluated**

**Clinical Pearl / High-Yield Fact**
A critical aspect of ECT is the discontinuation of MAOIs at least 2 weeks before the procedure to prevent hypertensive crises. This is because MAOIs can cause persistent inhibition of MAO, leading to unpredictable and severe hypertension during ECT.

**Correct Answer:** D. Discontinue the MAOI for at least 2 weeks before ECT
