Answer 2

Correct Answers:

1.3

Rationale :

🔵 Step 1: Convert the client’s weight from pounds to kilograms.

176 lb ÷ 2.2 = 80 kg

🔵 Step 2: Calculate the prescribed dose.

5 mcg/kg × 80 kg = 400 mcg

🔵 Step 3: Use the concentration to calculate the volume.

400 mcg ÷ 300 mcg/mL = 1.33 mL,

rounded to 1.3 mL

Rationale :

🟠 Step 1: Determine how many capsules are needed per dose.

500 mg ÷ 250 mg/capsule = 2 capsules per dose

🟠 Step 2: Calculate the total number of doses per day.

Every 12 hours = 2 doses per day

Answer 4

Correct Answers:

38

Rationale :

🟢 Step 1: Identify total volume and infusion time.

Volume = 75 mL, Time = 30 minutes

🟢 Step 2: Use the IV flow rate formula:

gtt/min = (Volume × Drop factor) ÷ Time

(75 mL × 15 gtt/mL) ÷ 30 min

1,125 ÷ 30 = 37.5

🟢 Step 3: Round to the nearest whole number:

38 gtt/min

Answer 5

Correct Answers:

30

Rationale :

🟣 Step 1: Determine the concentration of insulin in the solution.

100 units ÷ 250 mL = 0.4 units/mL

🟣 Step 2: Use the formula:

mL/hour = Prescribed units/hour ÷ Concentration

12 units/hour ÷ 0.4 units/mL

30 mL/hour

🟣 Step 3: No rounding is required.
