Question 1
The physician has ordered a medication drip at 103 units/kg/hr. The medication is
supplied in 25,000 units/500 mL. Your patient weighs 220 lbs. You should administer
____ mL/hr.
A. 206
B. 190
C. 215
D. 180
CORRECT ANSWER: A. 206
RATIONALE
Convert weight to kg: 220 ÷ 2.2 = 100 kg. Dose = 103 units × 100 kg = 10,300 units/hr.
Concentration = 25,000 units ÷ 500 mL = 50 units/mL. Rate = 10,300 ÷ 50 = 206 mL/hr.
, Question 2
The patient weighs 700 grams. You are given orders to administer 1 mEq/kg IV. The
medication is available in 0.5 mEq/mL. The dose to be given would be ___ mL.
(record your answer using one decimal place)
A. 1.4
B. 1.5
C. 1.3
D. 1.6
CORRECT ANSWER: A. 1.4
RATIONALE
Weight in kg: 700 g ÷ 1000 = 0.7 kg. Dose = 1 mEq × 0.7 = 0.7 mEq. Volume = 0.7 ÷ 0.5 = 1.4
mL.
Question 3
The physician orders a medication to be given at 1 mg/kg/day. The patient weighs
265 lbs. The medication is available as 100 mg/mL. You should administer ___ mL of
the medication. (record your answer using one decimal place)
A. 1.2
B. 1.3
C. 1.1
D. 1.4
CORRECT ANSWER: A. 1.2
RATIONALE
Weight in kg: 265 ÷ 2.2 = 120.45 kg. Dose = 1 mg × 120.45 = 120.45 mg. Volume = 120.45 ÷
100 = 1.2 mL.
