Answer to Question 1

D
Feedback:
Vitamin B6 would further decrease the therapeutic effects of levodopa and is contraindicated with levodopa, so the nurse would question this order. Pramipexole, diphenhydramine, and trihexyphenidyl are all useful adjunctive drugs when Parkinson's disease is no longer controlled with levodopa therapy alone.

Answer to Question 2

B
Feedback:
Lifestyle changes should be instituted before drug therapy if at all possible. If drug therapy is used, a mild diuretic may be tried first, with monitoring of blood glucose and electrolyte levels on a regular basis. Calcium channel blockers have been used to treat hypertension in children and may be among the first considerations if drug therapy other than mild diuretics is needed. Beta-blockers have been used with success in some children; adverse effects may limit their usefulness in others. The safety and efficacy of the angiotensin-converting-enzyme (ACE) inhibitors and the angiotensin-receptor blockers (ARBs) have not been established in children.
