- A. Schedule I drug
- B. Schedule II drug
- C. Schedule III drug
- D. Schedule IV drug
Correct Answer: B
Rationale: Narcotics such as morphine are considered schedule II drugs because of the high abuse potential with severe dependence liability. Schedule I drugs have high abuse potential and no accepted medical use. Schedule III drugs have a lesser abuse potential than schedule II drugs and an accepted medical use. Schedule IV drugs have low abuse potential and limited dependence liability.
A patient needs 500 mL of an infusion over 5 hours. The drop factor is 10 gtt/mL. Calculate the flow rate in drops per minute.
- A. 16.67 gtt/min
- B. 20 gtt/min
- C. 25 gtt/min
- D. 50 gtt/min
Correct Answer: B

An order is written for a patient to receive 1000 mL of normal saline IV over 8 hours. If the IV infusion set is a microdrip set that delivers 60 drops/mL, how many drops per minute should the patient be receiving?
- A. 60 drops/min
- B. 120 drops/min
- C. 240 drops/min
- D. 480 drops/min
Correct Answer: B
Rationale: If a patient were to receive 1000 mL in 8 hours, dividing 1000 by 8 would mean that the patient would receive 125 mL in 1 hour, or 60 minutes. Setting up the equation, 60 drops/mL X = 125 mL/60 min, and cross-multiplying, the answer is 120 drops/min.
