Question

A nurse is preparing to administer risperidone 25 mg 1M. After reading the label, how many mL should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer 1

Correct Answers:

0.67

Rationale :

🔹 Use formula: Dose ordered ÷ Concentration = Volume. (25 ÷ 37.5 = 0.67 mL).

🔹 The nearest hundredth is 0.67 mL; correct rounding is essential in pediatric and adult psych meds.

🔹 Using a leading zero avoids misinterpretation (0.67 not .67).

Answer 2

Correct Answers:

500

Rationale :

🟢 Labels must be interpreted correctly to avoid dosing errors in adolescents.

🟢 Calcium carbonate dosing is typically listed as elemental calcium content.

🟢 Teaching adolescents fosters medication self-management.

🟢 Calculating per tablet helps determine how many tablets to meet 1,300 mg/day.

🟢 Nurses must emphasize daily adherence for bone health.

Answer 4

Correct Answers:

400

Rationale :

♦ Formula: Volume ÷ Time (100 ÷ 0.25 hr = 400 mL/hr).

♦ IV pumps require whole numbers, so round properly.

♦ Infusing too slowly risks ineffective treatment; too fast risks fluid overload.

♦ Correct programming prevents pump alarms and patient harm.

♦ Quick calculations are essential for short-infusion meds.

Answer 5

Correct Answers:

850

Rationale :

🔶 1 g = 1,000 mg; therefore 0.85 g × 1,000 = 850 mg.

🔶 Conversion ensures accuracy in pediatric safe ranges.

🔶 Using correct units prevents 10-fold dosing errors.

🔶 Nurses must always check metric conversions in pediatrics.

🔶 Double-checking conversions is a safety standard.

Answer 6

Correct Answers:

0.73

Rationale :

💠 Convert weight: 32 ÷ 2.2 = 14.5 kg.

💠 Required dose: 14.5 × 0.1 = 1.45 mg.

💠 Supply: 2 mg/mL → 1.45 ÷ 2 = 0.73 mL.

Answer 7

Correct Answers:

63

Rationale :

✔ Formula: Volume ÷ Time = 500 ÷ 8 = 62.5 → 63 mL/hr.

✔ IV pump requires whole numbers.

✔ Ensures steady hydration for pediatric safety.

✔ Prevents rapid shifts in fluid and electrolytes.

✔ Monitoring IV flow avoids complications like infiltration.

Answer 8

Correct Answers:

3.5

Rationale :

🌟 Convert weight: 52 ÷ 2.2 = 23.6 kg.

🌟 Required dose: 7.5 × 23.6 = 177 mcg/day.

🌟 Supply: 50 mcg/mL → 177 ÷ 50 = 3.54 → 3.5 mL

Answer 9

Correct Answers:

1.5

Rationale :

🔵 100 mg = 5 mL; so 150 ÷ 100 × 5 = 7.5 mL.

🔵 Convert mL to tsp: 5 mL = 1 tsp → 7.5 ÷ 5 = 1.5 tsp.

Answer 10

Correct Answers:

83

Rationale :

🟣 Formula: Volume ÷ Time = 1000 ÷ 12 = 83.3 → 83 mL/hr.

🟣 Infusion rate prevents fluid overload in pediatrics.

🟣 Round to whole number for IV pump programming.

🟣 Consistent rate supports stable hydration.

🟣 Nurses monitor I&O balance closely.
