Answer to Question 1

D
Feedback:
When digoxin and diuretics are used concomitantly, the risk of digoxin toxicity is increased. The patient is at risk for hypokalemia, not hyperkalemia. The patient is not at a particular risk for hyperglycemia or tachycardia.

Answer to Question 2

C
Feedback:
Dexamethasone is considered the corticosteroid of cerebral edema. It is thought to penetrate the bloodbrain barrier more readily and achieve higher concentrations in cerebrospinal fluid. Cortisone is the drug of choice for adrenal insufficiency. Prednisone is the glucocorticoid of choice in nonendocrine disorders in which anti-inflammatory, antiallergic, antistress, and immunosuppressive effects are desired. Fluticasone (Flonase) is administered by oral inhalation.
