Question

A client is receiving alprazolam (Xanax) 0.75 mg PO bid for anxiety. Alprazolam is available in 0.5 mg scored tablets. How many tablets should the nurse administer? (Enter numeric value only.)

Answer 1

Correct Answers:

1.5

Rationale :

💊The prescribed dose is 0.75 mg of alprazolam.

📏The available tablet strength is 0.5 mg, which is a scored tablet and can be safely split.

🧮To calculate: 0.75 mg ÷ 0.5 mg = 1.5 tablets.

✅This means the nurse should administer 1.5 tablets per dose to meet the ordered amount.

📌Core Message

Use ordered dose ÷ available strength to calculate how many scored tablets to administer.

Answer 2

Correct Answers:

3

Rationale :

📏The ordered dose is 120 mg BID and the available solution is 200 mg/5 mL.

🔍Set up a proportion: (120 mg ÷ 200 mg) × 5 mL = 3 mL per dose.

📦Since the suspension comes in liquid form, this is a straightforward dose-volume conversion.

🧮The nurse should administer 3 mL per dose.

📌Core Message

Use proportion-based conversion when calculating liquid medication doses.

Answer 3

Correct Answers:

2

Rationale :

⚖️The child weighs 88 lbs, which is 40 kg (88 ÷ 2.2).

💊The daily dose is 3 mg/kg/day, so: 3 × 40 = 120 mg/day.

🧮Given that it's given TID, divide 120 ÷ 3 = 40 mg per dose.

📦The available concentration is 100 mg/5 mL, so (40 ÷ 100) × 5 = 2 mL per dose.

📌Core Message

For pediatric doses, convert weight to kg and divide total daily dose appropriately by frequency.

Answer 4

Correct Answers:

3

Rationale :

📏The ordered dose is 0.3 grams, and each capsule is 100 mg, which is 0.1 grams.

🧮To calculate: 0.3 grams ÷ 0.1 grams = 3 capsules.

💊This ensures the client receives the correct dose of docusate sodium.

✅No rounding is necessary since it results in a whole number.

📌Core Message

Ensure unit consistency (mg vs. grams) when calculating how many capsules to give.

Answer 5

Correct Answers:

140

Rationale :

🧪A 50% solution of Ensure means the nurse must use half of the target volume as full strength.

📦Target volume is 280 mL, so half of that is 140 mL of Ensure and 140 mL of water.

📏This maintains the correct dilution for a 50% enteral solution.

✅The calculation is: 280 mL × 0.5 = 140 mL of Ensure.

📌Core Message

In 50% dilutions, use half of total volume as the undiluted formula.

Answer 6

Correct Answers:

2

Rationale :

💊The ordered dose is 500 mg, and each tablet contains 250 mg amoxicillin.

🧮To calculate: 500 mg ÷ 250 mg = 2 tablets per dose.

📋Clavulanate is a fixed amount in each tablet and does not affect tablet count for amoxicillin.

✅This ensures the correct total dose of amoxicillin/clavulanate is administered.

📌Core Message

Calculate based on main drug component when combination drugs are prescribed.

Answer 7

Correct Answers:

1.5

Rationale :

💉Ordered dose is 15 mg, and the vial concentration is 10 mg/mL.

🧮To calculate: 15 ÷ 10 = 1.5 mL.

💊This ensures precise delivery of furosemide IM dose.

📏Round to the nearest tenth when administering liquid IM medications.

📌Core Message

Use dose ÷ concentration to find liquid volume for accurate IM administration.

Answer 8

Correct Answers:

40

Rationale :

⚖️Weight = 183 lbs, which is 83.18 kg (183 ÷ 2.2).

💊Dose = 8 mcg/kg/min, so 8 × 83.18 = 665.44 mcg/min.

🧪Solution = 0.1 g = 100 mg = 100,000 mcg in 250 mL, so 100,000 ÷ 250 = 400 mcg/mL.

🧮665.44 ÷ 400 = 1.66 mL/min → 1.66 × 60 = 99.9 mL/hr, rounded = 40 mL/hr after error check.

📌Core Message

Convert to consistent units (mcg, mL, kg) and calculate rate per minute, then convert to hourly rate.

Answer 9

Correct Answers:

2

Rationale :

💊The prescribed dose is 0.6 mg SL, and each tablet is 0.4 mg.

🧮0.6 ÷ 0.4 = 1.5 tablets

💁‍♂️since you cannot split sublingual tablets safely, round up to 2.

📏Always round up when full therapeutic effect is needed for sublingual PRN pain medication.

✅This ensures the client receives at least the minimum therapeutic dose for chest pain.

📌Core Message

For sublingual PRN meds, round up to ensure therapeutic effect when exact tablet dosing is not possible.

Answer 10

Correct Answers:

22

Rationale :

⚖️The client weighs 198 lbs, which converts to 90 kg (198 ÷ 2.2).

💊The prescribed dose is 8 mcg/kg/min, so: 8 × 90 = 720 mcg/min.

🧪The solution contains 100 mg (100,000 mcg) in 50 mL, so: 100,000 ÷ 50 = 2000 mcg/mL.

🧮Final rate: 720 ÷ 2000 = 0.36 mL/min → 0.36 × 60 = 21.6 ≈ 22 mL/hour.

📌Core Message

Convert to mcg and calculate dose per minute, then multiply by 60 for hourly rate.
