Question

A client on the palliative care unit is receiving midazolam 3 mg SUBQ every 2 hours PRN for terminal agitation and intractable hiccups. The medication is available in a 5 mL ampoule labeled. "2 mg/mL." How many mL should the nurse administer for each dose? (Enter the numerical value only.)

Answer 1

Correct Answers:

1.5

Rationale :

🧪The ordered dose is 3 mg, and the available concentration is 2 mg/mL.

📏To find the volume to administer, apply the formula: Dose ÷ Concentration = Volume.

📊So, 3 mg ÷ 2 mg/mL = 1.5 mL.

💉This calculation ensures the client receives the exact prescribed dose of midazolam for comfort care.

📌Core Message

Use dose ÷ concentration to calculate the volume to administer for injectable medications.

Answer 2

Correct Answers:

1.3

Rationale :

⚖️Convert weight to kg: 176 lbs ÷ 2.2 = 80 kg.

💊Next, multiply the prescribed dose: 5 mcg × 80 kg = 400 mcg/day.

🧮Now use: 400 mcg ÷ 300 mcg/mL = 1.33 mL, rounded to 1.3 mL.

📌This ensures accurate subcutaneous administration of filgrastim according to weight-based dosing.

📌Core Message

Convert weight to kg, multiply by dose/kg, then divide by concentration to find the correct volume in mL.

Answer 3

Correct Answers:

4

Rationale :

📆The client is prescribed 500 mg every 12 hours, which equals 1000 mg/day.

💊The capsules are 250 mg each, so 1000 mg ÷ 250 mg = 4 capsules daily.

🔢This accounts for two doses daily, ensuring full daily coverage.

✅Correct capsule counting avoids under- or overdosing.

📌Core Message

Calculate total daily dose and divide by individual capsule strength to determine capsules per day.

Answer 4

Correct Answers:

38

Rationale :

⏱️To calculate drops/minute: use the formula: (Volume × Drop factor) ÷ Time.

💧(75 mL × 15 gtt/mL) ÷ 30 min = 1125 ÷ 30 = 37.5, rounded to 38 gtt/min.

📉This ensures accurate infusion rate to deliver medication within the ordered time.

💉Proper flow rate protects against under- or overdosing via IV delivery.

📌Core Message

Use (mL × drop factor) ÷ minutes to determine manual IV flow rates in gtt/min.

Answer 5

Correct Answers:

30

Rationale :

💊The IV solution contains 100 units in 250 mL, so: 100 ÷ 250 = 0.4 units/mL.

🧮To deliver 12 units/hour: 12 ÷ 0.4 = 30 mL/hour.

🔁This rate provides the exact dose while maintaining stable blood glucose.

✅Correct pump programming is essential for safe insulin titration.

📌Core Message

Calculate mL/hour by dividing prescribed units by the unit concentration per mL.

Answer 6

Correct Answers:

30

Rationale :

📆The client needs 150 mg twice daily, which equals 300 mg/day.

💧The solution is 10 mg/mL, so: 300 mg ÷ 10 mg/mL = 30 mL/day.

🧪Daily dosing ensures consistent antiretroviral therapy.

📌Precise volume supports effective HIV treatment adherence.

📌Core Message

Multiply dose per administration by doses/day, then divide by concentration to find daily volume.

Answer 7

Correct Answers:

2

Rationale :

💊Each tablet contains 1000 mg amoxicillin + 62.5 mg clavulanate.

🧮The ordered dose is 2000 mg/125 mg, so 2 tablets are needed to reach both amounts.

✅Administering 2 extended-release tablets ensures correct combination dosing.

🩺Proper dosing improves bacterial eradication and treatment efficacy.

📌Core Message

For combination medications, ensure both components match the prescribed dose when determining number of tablets.

Answer 8

Correct Answers:

0.7

Rationale :

💉The dose is 410 mcg, and the available solution is 600 mcg/mL.

🧮So, 410 ÷ 600 = 0.683, rounded to 0.7 mL.

📏This volume ensures safe and accurate subcutaneous administration.

📌Correct dosing is essential for managing post-transplant neutropenia.

📌Core Message

Divide prescribed mcg by concentration in mcg/mL to calculate the volume to administer.

Answer 9

Correct Answers:

1

Rationale :

💉Each vial contains 200 mg in 2 mL, or 100 mg/mL.

🧪The ordered dose is 100 mg, so 100 ÷ 100 = 1 mL.

📏Administering the correct volume prevents IM irritation or underdosing.

💊Precise measurement ensures effective antiemetic relief postoperatively.

📌Core Message

For IM dosing, divide prescribed dose by concentration per mL to determine volume to give.

Answer 10

Correct Answers:

250

Rationale :

🧪To calculate mL/hour: 500 mL ÷ 2 hours = 250 mL/hour.

💉This maintains the correct antibiotic infusion time for therapeutic effect.

⏱️Programming the pump properly avoids too rapid or too slow delivery.

✅Steady infusion ensures proper tissue drug levels.

📌Core Message

Use volume ÷ time (in hours) to determine the correct infusion pump rate in mL/hour.
