Final answer:
The nurse should inform the student that temporary memory loss is the most common adverse effect of electroconvulsive therapy (ECT).
Step-by-step explanation:
Electroconvulsive therapy (ECT) is a treatment for certain mental disorders that involves passing electrical current through the brain to induce controlled seizures. The nurse should inform the student that temporary memory loss is the most common adverse effect of ECT, as supported by research (Donahue, 2000). This temporary memory loss usually affects the period immediately before and after the treatment.
