Use a leading zero if it applies.
Do not use a trailing zero.). capsule(s).
The Correct Answer is ["3"]
Step 1 is to determine the total amount of medication needed. The doctor ordered 300 mg of phenytoin and each capsule contains 100 mg. So, we divide the total amount ordered by the amount per capsule: 300 mg ÷ 100 mg/capsule = 3 capsules.
So, the correct answer is 3 capsules.

Correct Answer is ["0.8 mL"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms. So, 183 lb ÷ 2.2 = 83.18 kg (rounded to the nearest hundredth). Step 2 is to calculate the total amount of medication needed. So, 0.1 mg/kg × 83.18 kg = 8.32 mg (rounded to the nearest hundredth). Step 3 is to calculate the volume to administer. So, 8.32 mg ÷ 10 mg/mL = 0.832 mL. Rounding off to the nearest tenth, the nurse should administer 0.8 mL of furosemide.
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.
