1 :
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.)

Hint : 💉 IV bolus infusion rate

Correct Answers:

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.

2 :
A nurse is preparing to administer regular insulin 0.1 unit/ kg/hr via continuous IV infusion to a client who weighs 70 kg. Available is regular insulin 100 units in 0.9% sodium chloride 100 m'. 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.)

Hint : 🧪 Weight-based insulin dose

Correct Answers:

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

3 :
A nurse is preparing to administer potassium chloride 30 mEq PO every 12 hr. Available is potassium chloride 10 mEq sustained-release tablets. HOW many tablets Should the nurse administer per dose? (Round the answer to the nearest whole number. use a leading zero if it applies, DO not use a trailing zero.)

Hint : 🟠 Electrolyte tablet calculation

Correct Answers:

Rationale :

💫 Prescribed dose is 30 mEq

💫available is 10 mEq per tablet

💫 30 ÷ 10 = 3 tablets

Hint : 🥤Liter to ounces

Correct Answers:

Rationale :

🌟 Conversion: 1 L = 33.8 oz,

🌟so 2 L = 67.6 oz → round = 68 oz

A nurse is preparing to administer oxytocin 3 milliunits/min via continuous IV infusion to a client for augmentation of labor. Available is oxytocin 10 units in 0.9% sodium chloride 1.000 mt. 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.)

Hint : 👶Oxytocin drip rate

Correct Answers:

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
