1. A nurse is preparing to administer phenytoin 0.2 g PO. The available dosage is 100 mg
capsules. How many capsules should the nurse administer?
A. 2 capsules
B. 1 capsule
C. 0.5 capsules
D. 4 capsules
Answer: A
Conceptual Explanation: First, convert grams to milligrams: 0.2 g * 1000 = 200 mg. Then,
divide the desired dose by the available dose: 200 mg / 100 mg = 2 capsules.
2. A nurse is preparing to administer amoxicillin 250 mg PO. The available concentration is
125 mg/5 mL. How many mL should the nurse administer?
A. 2 mL
B. 5 mL
,C. 10 mL
D. 15 mL
Answer: C
Conceptual Explanation: Use the formula (Desired/Have) * Volume. (250 mg / 125 mg) *
5 mL = 2 * 5 mL = 10 mL.
3. A nurse is preparing to administer 0.9% sodium chloride 1,000 mL IV to infuse over 8 hr.
The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest whole
number)
A. 80 mL/hr
B. 125 mL/hr
C. 100 mL/hr
D. 150 mL/hr
Answer: B
Conceptual Explanation: Divide the total volume by the total time in hours: 1,000 mL / 8
hr = 125 mL/hr.
4. A provider prescribes heparin 5,000 units SC every 12 hr. The available heparin injection is
10,000 units/mL. How many mL should the nurse administer per dose?
A. 2 mL
B. 1 mL
, C. 0.5 mL
D. 0.25 mL
Answer: C
Conceptual Explanation: Use the formula (Desired/Have) * Volume. (5,000 units / 10,000
units) * 1 mL = 0.5 mL.
5. A nurse is preparing to administer cefazolin 1 g IM. The nurse reconstitutes a 1 g vial with
2.5 mL of sterile water to yield a concentration of 330 mg/mL. How many mL should the
nurse administer? (Round to the nearest tenth)
A. 0.3 mL
B. 3.0 mL
C. 2.5 mL
D. 3.3 mL
Answer: B
Conceptual Explanation: First, convert 1 g to 1,000 mg. Then, (1,000 mg / 330 mg) * 1 mL
= 3.0303… mL. Rounded to the nearest tenth, it is 3.0 mL.
6. A nurse is calculating the intake for a client during a 8-hour shift. The client had: 4 oz of
juice, 6 oz of broth, and 200 mL of water. How many mL should the nurse document as the
total intake?
A. 500 mL
