Answer to Question 1

B
Feedback:
Anticholinergics can produce urinary hesitancy and urinary retention, conditions that would aggravate the signs and symptoms of prostatic hypertrophy. Older patients given anti-cholinergics should be encouraged to empty the bladder before taking the drug. These drugs are used to treat parkinsonism. Thyroid conditions and cardiac arrhythmias are not cautions or contraindications to the use of these drugs.

Answer to Question 2

D
Feedback:
St. John's wort can interact with oral contraceptives that alter drug metabolism, which can decrease the effectiveness of the contraceptive. Analgesics, antibiotics, and antihistamines can be taken in combination with St. John's wort without known adverse effects.
