A client receives a prescription for an intravenous (IV) infusion of 5% Dextrose Injection, USP in 0.45% Sodium Chloride Injection, USP at 55 mL/hour. The IV administration set delivers 10 gtt/mL. The nurse should regulate the drop rate to deliver how many gtts/minute? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["9"]
To calculate the drop rate in gtts/minute, we can use the following formula:
Drop rate (gtts/minute) = (Volume (mL) x Drop factor) / Time (minutes)
Volume to be infused: 55 mL/hour
Drop factor: 10 gtt/mL
Time: 60 minutes/hour
(55 mL x 10 gtt/mL) / 60 minutes = 9.17 gtts/minute
We can round this value to the nearest whole number to get 9 gtts/min

Correct Answer is ["75"]
Explanation
The healthcare provider prescribes an IV solution of isoproterenol 1 mg in 250 mL of Dextrose in Water (D/W) at a rate of 300 mcg/hour.
Since 1 mg is equivalent to 1000 mcg, the concentration of isoproterenol in the IV solution is 4 mcg/mL (1000 mcg / 250 mL).
Since the healthcare provider prescribes 300 mcg/hour of isoproterenol, the nurse should program the infusion pump to deliver 75 mL/hour of the IV solution (300 mcg/hour / 4 mcg/mL).
Correct Answer is ["4"]
Explanation
The client is receiving a prescription for penicillin 1.2 million units IM.
The available vial is labeled "600,000 units/2 mL", so the concentration of penicillin in the solution is 300,000 units/mL (600,000 units / 2 mL).
Since the healthcare provider prescribes 1.2 million units of penicillin, the nurse should administer 4 mL of medication (1.2 million units / 300,000 units/mL).
