Answer to Question 1

ANS: A
Because nonsteroidal anti-inflammatory drugs (NSAIDs) can increase lithium levels as much as 60, they should not be used by patients taking lithium. Aspirin does not have this effect. Lithium induces polyuria in 50 to 70 of patients, so patients should be advised to drink extra fluids, especially during exercise. Antihistamines have anticholinergic effects, which cause urinary hesitancy; this can be uncomfortable when patients experience the polyuria associated with lithium use. Muscle weakness and tremors can occur with lithium; tremors can be treated with beta blockers or by altering the lithium regimen.

Answer to Question 2

ANS: C
Patients taking an MAOI should be counseled to follow strict dietary restrictions and to avoid all foods containing tyramine. Patients who consume such foods when taking an MAOI experience a hypertensive episode. Antihypertensive medications, given with an MAOI, will result in hypotension. Grapefruit juice does not alter the metabolism of an MAOI. SSRIs and MAOIs, when administered together, cause a serotonin syndrome.
