Question

A client is receiving a secondary infusion of vancomycin 1,500 mg in 250 ml to be infused over two hours. The intravenous (IV) administration set delivers 15 gtt/ml. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If sounding is required, round to the nearest whole number.)

Answer 1

Correct Answers:

31

Rationale :

🧪Total volume = 250 mL over 2 hours = 120 minutes.

📏Use the formula: (Volume × Drop factor) ÷ Time = (250 × 15) ÷ 120 = 31.25.

🧮Rounded to the nearest whole number = 31 gtt/min.

💉Set the IV to deliver 31 drops per minute for accurate administration.

📌Core Message

Use (volume × drop factor) ÷ time in minutes to calculate manual IV drip rate in gtt/min.

Answer 2

Correct Answers:

12000

Rationale :

🧪The IV contains 20,000 units in 500 mL → 20,000 ÷ 500 = 40 units/mL.

💁‍♂️25 mL/hr × 12 hr = 300 mL → 300 mL × 40 units = 12,000 units.

📊This is the total amount of heparin the client receives in 12 hours.

💉Monitoring total dosage ensures safe anticoagulant management.

📌Core Message

Multiply volume infused by concentration to calculate total drug received over time.

Answer 3

Correct Answers:

0.42

Rationale :

📦Reconstituted: 0.3 mg in 2 mL → 0.3 ÷ 2 = 0.15 mg/mL.

👉0.0625 mg ÷ 0.15 mg/mL = 0.4167, round to 0.42 mL.

💉Administer 0.42 mL of interferon beta-1b.

🧫Accurate rounding to the nearest hundredth is critical for subcutaneous dosing.

📌Core Message

Determine the reconstituted concentration, then divide the ordered dose by that value to find the correct volume.

Answer 4

Correct Answers:

111

Rationale :

💁‍♂️1,000 mL ÷ 9 hr = 111.1 mL/hr, round to 111 mL/hr.

👉Infusion pumps require whole numbers unless specified otherwise.

👍This ensures the full volume is delivered evenly across the 9-hour period.

🤝Correct programming prevents underdosing or fluid overload.

📌Core Message

Use volume ÷ time in hours to calculate the infusion rate in mL/hr for pump settings.

Answer 5

Correct Answers:

2.4

Rationale :

🧨Cefazolin 1 g = 1,000 mg in 3 mL.

💢800 mg ÷ 1,000 mg = 0.8 → 0.8 × 3 mL = 2.4 mL.

💉Administer 2.4 mL IM to deliver the prescribed 800 mg dose.

📏Proportional dosing ensures accuracy with partial vial doses.

📌Core Message

Use (desired ÷ available dose) × total volume to calculate how much to draw up.

Answer 6

Correct Answers:

42

Rationale :

📦500 mL over 2 hours = 120 minutes.

🧮(500 × 10) ÷ 120 = 41.67, round to 42 gtt/min.

💧Use a manual IV set calibrated to 10 gtt/mL for precise flow control.

🧫Manual regulation requires rounding to the nearest whole drop.

📌Core Message

To find gtt/min, use (volume × drop factor) ÷ minutes and round appropriately.

Answer 7

Correct Answers:

2000

Rationale :

⚖️88 lb ÷ 2.2 = 40 kg.

🧮50 mg/kg/day × 40 kg = 2,000 mg/day.

💊This is the full daily dose the child should receive.

🧫Ensure accurate weight conversion for pediatric calculations.

📌Core Message

Use weight-based dosing by converting pounds to kilograms, then multiplying by the dose per kg.

Answer 8

Correct Answers:

21

Rationale :

📦2,000 mL in 24 hours = 1,440 minutes.

🧮(2,000 × 15) ÷ 1,440 = 20.83, round to 21 gtt/min.

💧This is the manual drip rate using a 15 gtt/mL set.

📏Ensure even infusion throughout 24 hours.

📌Core Message

Calculate gtt/min using the full 24-hour timeframe converted to minutes.

Answer 9

Correct Answers:

2.4

Rationale :

👉Supplied: 500 mcg in 2 mL → 250 mcg/mL.

💁‍♂️0.6 mg = 600 mcg → 600 ÷ 250 = 2.4 mL.

💉Administer 2.4 mL IV to deliver 0.6 mg of digoxin.

📏Unit conversion from mg to mcg is essential.

📌Core Message

Convert mg to mcg, then divide by mcg/mL concentration to determine volume.

Answer 10

Correct Answers:

100

Rationale :

🔵150 mL over 90 minutes = 1.5 hours.

🔴150 ÷ 1.5 = 100 mL/hr.

🟡Program the pump to 100 mL/hr to ensure timely delivery.

🧫Correct flow rates help maintain therapeutic drug levels.

📌Core Message

Divide infusion volume by time in hours to get the correct mL/hr pump rate.
