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 :

🎗️Identify: Volume = 100 mL; Time = 15 min → 0.25 hr

🎗️Formula: Flow rate (mL/hr) = Total Volume ÷ Time (hr)

🎗️Solve: 100 ÷ 0.25 = 400 mL/hr

Answer 2

Correct Answers:

7

Rationale :

✅Identify: Dose = 0.1 × 70 = 7 units/hr;

✅Concentration = 100 units/100 mL → 1 unit/mL

✅Formula: Flow rate (mL/hr) = Dose ÷ Concentration

✅Solve: 7 ÷ 1 = 7 mL/hr

Answer 3

Correct Answers:

3

Rationale :

✅Identify: Dose per administration = 30 mEq; Tablet = 10 mEq

✅Formula: Number of tablets = Dose ÷ Tablet strength

✅Solve: 30 ÷ 10 = 3 tablets per dose

Answer 5

Correct Answers:

0.5

Rationale :

✅Identify: Dose = 0.2 mg; Concentration = 0.4 mg/mL

✅Formula: Volume (mL) = Dose ÷ Concentration

✅Solve: 0.2 ÷ 0.4 = 0.5 mL

Answer 6

Correct Answers:

18

Rationale :

✅Identify: Dose = 3 milliunits/min; Concentration = 10 units/1,000 mL → 10,000 milliunits/1,000 mL = 10 milliunits/mL

✅Formula: Flow rate (mL/hr) = (Dose ÷ Concentration) × 60

✅Solve: (3 ÷ 10) × 60 = 0.3 × 60 = 18 mL/hr

Answer 7

Correct Answers:

0.25

Rationale :

✅Identify: Dose = 0.5 mg; Concentration = 1 mg/0.5 mL → 2 mg/mL

✅Formula: Volume (mL) = Dose ÷ Concentration

✅Solve: 0.5 ÷ 2 = 0.25 mL

Answer 8

Correct Answers:

75

Rationale :

✅Identify: 1 oz = 30 mL → 2.5 × 30 = 75 mL

✅Round: 75 mL

Answer 9

Correct Answers:

25.5

Rationale :

✅Identify: Dose = 1.7 mg/min → 102 mg/hr (1.7 × 60);

✅Concentration = 1 g/250 mL → 1,000 mg/250 mL = 4 mg/mL

✅Formula: Flow rate (mL/hr) = Dose ÷ Concentration

✅Solve: 102 ÷ 4 = 25.5 mL/hr

Answer 10

Correct Answers:

25.5

Rationale :

✅Identify: Dose = 1.7 mg/min → 102 mg/hr (1.7 × 60);

✅Concentration = 1 g/250 mL → 1,000 mg/250 mL = 4 mg/mL

✅Formula: Flow rate (mL/hr) = Dose ÷ Concentration

✅Solve: 102 ÷ 4 = 25.5 mL/hr
