Question

Heparin 5,000 units IV is prescribed as a loading dose, to be administered over 5 minutes for a client with thrombophlebitis. The vial is labeled, "10,000 units/mL." How many ml. should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

Answer 1

Correct Answers:

0.5

Rationale :

💉The vial contains 10,000 units/mL of heparin.

🧮To give 5,000 units: 5,000 ÷ 10,000 = 0.5 mL.

📏Since the dose is to be given over 5 minutes, no rate adjustment is needed here.

🩺Accurate dosing prevents complications like bleeding or underdosing.

📌Core Message

Divide prescribed units by available concentration to find the correct mL to administer.

Answer 2

Correct Answers:

4.7

Rationale :

🧪The reconstituted concentration is 30 mg/mL.

🧮140 ÷ 30 = 4.67, which rounds to 4.7 mL.

💉Administering the correct volume ensures therapeutic drug levels.

📦Always round to the nearest tenth only if instructed.

📌Core Message

Divide the prescribed dose by concentration to determine mL to give.

Answer 3

Correct Answers:

100

Rationale :

🕒The total volume is 150 mL over 90 minutes.

🧮Convert 90 minutes to hours: 90 ÷ 60 = 1.5 hours.

📏150 ÷ 1.5 = 100 mL/hr.

💊Set the infusion pump to 100 mL/hr for safe delivery.

📌Core Message

Divide total volume by hours to get pump rate in mL/hr.

Answer 4

Correct Answers:

3

Rationale :

💊The prescribed dose is 120 mg of furosemide.

📏Recommended rate: 40 mg/min → 120 ÷ 40 = 3 minutes.

💉Slow IV push prevents ototoxicity or hypotension.

🕒Always check administration guidelines for rate limits.

📌Core Message

Divide total dose by mg/min rate to find administration time.

Answer 5

Correct Answers:

1

Rationale :

📦Midazolam available: 4 mg/2 mL → 2 mg/mL.

🧮2 ÷ 2 = 1 mL.

💉Administer 1 mL for the prescribed 2 mg.

📏Using the correct volume ensures safe procedural sedation.

📌Core Message

Divide prescribed dose by available concentration to get mL to administer.

Answer 6

Correct Answers:

2.4

Rationale :

🧨Reconstituted vial: 1 gram (1,000 mg) in 3.0 mL.

💁‍♂️800 ÷ 1,000 = 0.8 → 0.8 × 3.0 = 2.4 mL.

💉Administer 2.4 mL for an 800 mg dose.

📏Precision in reconstituted drugs is essential for IM effectiveness.

📌Core Message

Find the fractional dose of full vial, then multiply by total mL to get the amount to draw.

Answer 7

Correct Answers:

0.9

Rationale :

📦Hydromorphone: 10 mg/mL → 4 ÷ 10 = 0.4 mL.

🔵Hydroxyzine: 50 mg/mL → 25 ÷ 50 = 0.5 mL.

🧮0.4 + 0.5 = 0.9 mL total.

📌Core Message

Use dose ÷ concentration for each drug, then add both volumes for total mL.

Answer 8

Correct Answers:

440

Rationale :

📦Pantoprazole: 110 mL over 15 minutes.

🧮15 ÷ 60 = 0.25 hours.

📏110 ÷ 0.25 = 440 mL/hr.

💉Set secondary pump to 440 mL/hr for correct infusion timing.

📌Core Message

Divide volume by time in hours to find pump setting for secondary infusion.

Answer 9

Correct Answers:

16

Rationale :

📆800 mg every 6 hours = 4 doses/day.

💊Each tablet is 400 mg → 800 ÷ 400 = 2 tablets/dose.

🧮2 × 4 = 8 tablets/day.

📅Over 24 hours: 8 tablets × 2 days = 16 tablets in total.

📌Core Message

Multiply tablets per dose by daily frequency to get total daily tablets.

Answer 10

Correct Answers:

60

Rationale :

⚖️66 lb ÷ 2.2 = 30 kg.

💊2 mg/kg × 30 = 60 mg/dose.

🧪Gentamicin dosing requires weight-based calculation.

🧾Ensure accurate dosing to prevent renal toxicity or underdosing.

📌Core Message

Convert to kg, then multiply by mg/kg to get the dose in mg.
