A nurse is preparing to administer naloxone 10 mcg/kg IM to a client who weighs 165 lb. Available is naloxone 0.4 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.9"]
Step 1 is to convert the client’s weight from pounds to kilograms since the dosage is prescribed in mcg/kg. Given that 1 kg = 2.2 lb, we calculate:
165 lb ÷ 2.2 = 75 kg
Step 2 is to calculate the volume of naloxone to be administered. The prescribed dosage is 10 mcg/kg, so we first determine the total dose:
10 mcg/kg × 75 kg = 750 mcg
Next, we convert the available concentration of naloxone from mg/mL to mcg/mL:
0.4 mg/mL × 1000 mcg/mg = 400 mcg/mL
Now, we calculate the required volume by dividing the total dose by the concentration:
750 mcg ÷ 400 mcg/mL = 1.875 mL
Rounding to the nearest tenth, the correct amount to administer is 1.9 mL.

Correct Answer is ["0.75"]
Explanation
Step 1 is to convert mcg to mg. This is done by dividing the total amount of medication (750 mcg) by 1000 (since 1 mg = 1000 mcg). So, 750 mcg ÷ 1000 = 0.75 mg.
Correct Answer is ["83"]
Explanation
Step 1 is to calculate the total volume to be infused in mL/min. This is done by dividing the total volume (250 mL) by the time in minutes (30 min). So, 250 mL ÷ 30 min = 8.33 mL/min. Step 2 is to convert mL/min to gtt/min using the drop factor. So, (8.33 mL/min) × (10 gtt/mL) = 83.3 gtt/min. Round off to the nearest whole number, the correct answer is 83 gtt/min.
