A nurse provided medication education for a patient who takes phenelzine (Nardil) for depression. Which behavior indicates effective learning? The patient:
a. Monitors sodium intake and weight daily.
b. Wears support stockings and elevates the legs when sitting.
c. Consults the pharmacist when selecting over-the-counter medications.
d. Can identify foods with high selenium content, which should be avoided.
ANS: C
Over-the-counter medicines may contain vasopressor agents or tyramine, a substance that must be avoided when the patient takes MAOI antidepressants. Medications for colds, allergies, or congestion or any preparation that contains ephedrine or phenylpropanolamine may precipitate a hypertensive crisis. MAOI antidepressant therapy is unrelated to the need for sodium limitation, support stockings, or leg elevation. MAOIs interact with tyramine-containing foods, not selenium, to produce dangerously high blood pressure.
