Question

A nurse is preparing to administer cefazolin 1 g in 0.9% sodium chloride 100 mL via intermittent IV bolus over IS min to a client who is scheduled for a cesarean birth. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use leading zero if it applies. Do not use a trailing zero.)

Answer 1

Correct Answers:

400

Rationale :

🔹 Infusion rate is calculated using the formula:

🔹(Volume ÷ Time in minutes) × 60.

🔹 Client receives 100 mL over 15 minutes,

🔹 (100 ÷ 15) × 60 = 400 mL/hr.

Answer 2

Correct Answers:

7

Rationale :

✅ Weight-based doses require multiplying the dose by weight

✅ 0.1 units/kg/hr × 70 kg = 7 units/hr.

✅ Concentration is 100 units in 100 mL = 1 unit/mL

✅so dose equals volume.

✅ Final rate: 7 units/hr ÷ 1 unit/mL = 7 mL/hr.

Answer 6

Correct Answers:

18

Rationale :

🔶 Oxytocin dose ordered is 3 milliunits/min, which equals 180 milliunits/hr (3 × 60).

🔶 Available concentration is 10,000 milliunits in 1,000 mL

🔶 (since 1 unit = 1,000 milliunits).

🔶 Set up proportion: 10,000 mU : 1,000 mL = 180 mU : X mL.

🔶 Solving: X = (180 × 1,000) / 10,000 = 18 mL/hr.

Answer 7

Correct Answers:

0.25

Rationale :

🔷 Ordered: 0.5 mg; Available: 1 mg/0.5 mL.

🔷 Set up proportion: 1 mg : 0.5 mL = 0.5 mg : X mL.

🔷 Solving gives X = 0.25 mL.

Answer 9

Correct Answers:

26

Rationale :

✳️ Lidocaine ordered: 1.7 mg/min = 102 mg/hr (1.7 × 60).

✳️ Available: 1 g = 1,000 mg in 250 mL → 4 mg/mL.

✳️ Set up: 102 mg ÷ 4 mg/mL = 25.5 ≈ 26 mL/hr.
