- A. One
- B. Two
- C. I don't know
Correct Answer: B
Rationale: With a therapeutic index of 2, the toxic dose is twice the therapeutic dose. Taking two daily doses at once would reach this threshold, giving a 50:50 chance of toxicity.

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.
