Answer to Question 1

A
Feedback:
If a patient was to receive 500 mL in 8 hours, dividing 500 by 8 would mean that the patient would receive 62.5 mL in 1 hour, or 60 min. Setting up the equation, 15 drops/mL/X equals 62.5 mL/60 min; cross-multiplying, the answer will be 15 drops/min.

Answer to Question 2

D
Feedback:
First, using the formula: 2.2 pounds and 60 pounds: multiplied by kg, determine the child's weight in kg (60/2.2 = 27.27 kg). Next, using the formula: amount of drug prescribed times weight in kg, determine the dose in mcg the child should receive (30 multiplied by 27.27 = 0.818 mcg). Then to determine the amount of mg the child should receive, use the formula: 1 mg: 1,000 mcg = X mg: 818 mcg (818/1,000 = 0.818 mg).
