The primary healthcare provider (PHCP) prescribes 500 mL of 0.9% sodium chloride (normal saline) to infuse over four hours via intravenous microdrip tubing. The nurse sets the flow rate at how many drops per minute? Fill in the blank. Round your answer to the nearest whole number.
Correct Answer: 125 drops per minute
Rationale: Microdrip tubing has a drop factor of 60 gtts/mL. Calculate: (500 mL × 60 gtts/mL) ÷ (4 hr × 60 min/hr) = 30,000 gtts ÷ 240 min = 125 gtts/min.
A client with a stroke is prescribed alteplase. The prescription is for 0.9 mg/kg. The client weighs 61.81 kg (135.98 lbs). What is the total dose in milligrams (mg) that the client will receive? Fill in the blank. Round your answer to the nearest whole number.

The primary healthcare provider (PHCP) prescribes amoxicillin 80 mg/kg/day to be given in two divided doses. The infant weighs 8.72 kg (19.18 Ibs). The label of the medication reads 250 mg/mL of amoxicillin. How many mL of amoxicillin should the nurse administer for one dose? Fill in the blank. Record your answer using 1 decimal place.
Correct Answer: 1.4 mL
Rationale: Calculate daily dose: 80 mg/kg × 8.72 kg = 697.6 mg. Per dose: 697.6 mg ÷ 2 = 348.8 mg. Convert: 348.8 mg ÷ 250 mg/mL = 1.3952 mL, rounded to 1.4 mL.
The primary healthcare provider (PHCP) prescribes 400,000 units of penicillinG benzathine. The label on the medication reads penicillinG benzathine 300,000 units / 10 mL. How many milliliters will the nurse administer to the client? Fill in the blank. Round your answer to the nearest whole number.
Correct Answer: 13 mL
Rationale: Calculate: (400,000 units ÷ 300,000 units) × 10 mL = 1.333 × 10 = 13.33 mL, rounded to 13 mL.
