Answer to Question 1

B, C, D
Feedback:
Adverse effects include transient drowsiness, dizziness, weakness, fatigue, constipation, headache, insomnia, hypotension, nausea, and urinary frequency. Bone marrow suppression and coronary artery disease are not associated with therapy involving these drugs.

Answer to Question 2

A
Feedback:
The formula for calculating the child's dose using body surface area is surface area in m2 divided by 1.73 and then multiplied by adult dosage. Using the information supplied in this problem (0.4 1.73) 500 mg = 346 mg. Using the ratio and proportion method, 500 mg/5 mL = 346 mg/X mL; cross-multiplying yields 3.46 mL for the nurse to administer.
