Question

A nurse is preparing to administer cefazolin 1 g in OS% 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 a leading zero if it applies. Do not use a trailing zero.)

Answer 1

Correct Answers:

400

Rationale :

🔶 Use the formula: mL/hr = (Volume ÷ Time in minutes) × 60

🔶 100 mL ÷ 15 min = 6.67 mL/min,

🔶Then multiply by 60: 6.67 × 60 = 400 mL/hr

🔶 Rounding correctly to the nearest whole number is required: 400, not 399 or 401.

Answer 2

Correct Answers:

7

Rationale :

✴ Client weight = 70 kg, dosage = 0.1 unit/kg/hr

✴ → 70 × 0.1 = 7 units/hr

✴ Concentration = 100 units/100 mL, so 1 unit = 1 mL

✴ To give 7 units/hr, the pump must deliver 7 mL/hr

✴ Final step: Since 1 unit = 1 mL, deliver 7 mL/hr

Answer 6

Correct Answers:

18

Rationale :

🟣 Ordered: 3 milliunits/min, Available: 10 units in 1,000 mL

🟣 Convert 10 units = 10,000 milliunits → 10,000 mU/1,000 mL = 10 mU/mL

🟣 Needed: 3 mU/min → 3 ÷ 10 = 0.3 mL/min

🟣 Then, 0.3 mL/min × 60 = 18 mL/hr

Answer 8

Correct Answers:

74

Rationale :

🟡 Conversion: 1 oz = 29.57 mL → 2.5 oz × 29.57 = 73.93 ≈ 74 mL

Answer 9

Correct Answers:

25.5

Rationale :

🔴 Ordered: 1.7 mg/min

🔴Convert to mg/hr = 1.7 × 60 = 102 mg/hr

🔴 Available: 1 g = 1,000 mg in 250 mL → 1000 ÷ 250 = 4 mg/mL

🔴 Then: 102 mg/hr ÷ 4 mg/mL = 25.5 mL/hr
