Answer to Question 1

B
Feedback:
The nurse should question the order for hydrocodone. The ordered dose, 10 mg, is an adult dose and should not be given to a 5-year-old. Patients from 2 to 12 years of age should be given between 1.25 and 5 mg/dose. The other medications are all correct dosages for the age of the child for whom they were prescribed.

Answer to Question 2

B
Feedback:
Cardiac glycosides increase intracellular calcium and allow more calcium to enter myocardial cells. This action causes an increased force of myocardial contraction, an increased cardiac output, and renal perfusion that increases urine output. Cardiac glycosides also serve to slow the heart rate and decrease conduction velocity.
