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"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms. Given that 1 kg = 2.2 lb, we calculate:
183 lb ÷ 2.2 = 83.18 kg
Rounding to the nearest hundredth, the client’s weight is 83.18 kg.
Step 2 is to calculate the total amount of medication needed. The prescribed dosage is 0.1 mg/kg, so we calculate:
0.1 mg/kg × 83.18 kg = 8.32 mg
Rounding to the nearest hundredth, the total medication required is 8.32 mg.
Step 3 is to determine the volume to administer. The available concentration of furosemide is 10 mg/mL, so we divide:
8.32 mg ÷ 10 mg/mL = 0.832 mL
Rounding to the nearest tenth, the correct amount to administer is 0.8 mL.
Correct Answer is ["57"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms. We know that 1 kg is approximately 2.2 lb. So, the client’s weight in kg is 178 lb ÷ 2.2 lb/kg = 80.91 kg. Step 2 is to calculate the total dose of acetylcysteine. The total dose is 140 mg/kg × 80.91 kg = 11327.4 mg. Step 3 is to calculate the volume to administer. The volume is 11327.4 mg ÷ 200 mg/mL = 56.637 mL.
So, the correct answer is 57 mL after rounding to the nearest whole number.
