Question

A nurse is preparing to administer morphine 0.2 mg/kg IM to a child who weighs 77 lb. Available is morphine injection 10 mg/mL. How many ml should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer 1

Correct Answers:

0.7

Rationale :

💠Weight (lb) ÷ 2.2 = Weight (kg) 💠 77 lb ÷ 2.2 = 35 kg 💠Dose (mg) = 0.2 mg/kg × 35 kg 💠 Dose (mg) = 7 mg 💠Volume (mL) = Dose (mg) ÷ Concentration (mg/mL) 💠 Volume (mL) = 7 mg ÷ 10 mg/mL = 0.7 mL

Answer 2

Correct Answers:

50

Rationale :

🔷 Total daily dose ÷ Number of doses per day

200 mg ÷ 24 hr = 8.33 mg/hr

🔷 Dose interval (q6 hr) → Number of doses

24 hr ÷ 6 hr = 4 doses/day

🔷 Amount per dose = Total daily dose ÷ Number of doses

200 mg ÷ 4 = 50 mg

Answer 3

Correct Answers:

0.75

Rationale :

🔷 Order (DO) = 60 mg

🔷 Available (DH) = 80 mg / 1 mL

🔷 Formula:

mL to give = DO ÷ DH

🔷 Substitute:

mL to give = 60 mg ÷ 80 mg/mL

🔷 Calculate:

60 ÷ 80 = 0.75 mL

🔷 Round (to nearest hundredth):

0.75 mL (already at hundredth)

Answer 4

Correct Answers:

Choose the same day of each week to take this medication.

Rationale :

🎯Alendronate is taken once weekly, and choosing the same day each week improves consistency and absorption.

🎯It must be taken upon waking, with a full glass of water, 30 minutes before food, fluids, or other medications.

🎯The client must remain upright for 30 minutes to prevent esophageal irritation.

Why the others are wrong:

🎯The client cannot return to bed after taking alendronate because lying down increases the risk of esophageal irritation.

🎯 It must be taken alone—no meds, vitamins, calcium, or antacids within 30 minutes.

🎯 It must be taken in the morning upon waking, not in the evening.

Answer 5

Correct Answers:

1.9

Rationale :

🔷 Order (DO) = 187 mg

🔷 Available (DH) = 100 mg / 1 mL

🔷 Formula: mL to give = DO ÷ DH

🔷 Substitute: mL to give = 187 mg ÷ 100 mg/mL

🔷 Calculate: 187 ÷ 100 = 1.87 mL

🔷 Round to nearest tenth: 1.87 → 1.9 mL

Answer 6

Correct Answers:

0.5

Rationale :

🔷 Order (DO) = 20 mg

🔷 Available (DH) = 40 mg per tablet

🔷 Formula: tablets to give = DO ÷ DH

🔷 Substitute: 20 mg ÷ 40 mg/tablet

🔷 Calculate: 20 ÷ 40 = 0.5 tablets

🔷 Rounding: Already at nearest tenth → 0.5 tablets

Answer 7

Correct Answers:

3

Rationale :

🔷 Total ordered (per day) = 3.9 g

🔷 Convert g → mg:

3.9 g × 1000 mg = 3900 mg

🔷 Doses per day: every 12 hr = 2 doses/day

🔷 Amount per dose:

3900 mg ÷ 2 = 1950 mg per dose

🔷 Available (DH): 650 mg per tablet

🔷 Formula: tablets to give = 1950 mg ÷ 650 mg/tablet

🔷 Calculate:

1950 ÷ 650 = 3 tablets

🔷 Round to nearest whole number: already 3

Answer 8

Correct Answers:

3

Rationale :

🔷 Order (DO) = 1.5 mg

🔷 Available (DH) = 0.5 mg per tablet

🔷 Formula: tablets to give = DO ÷ DH

🔷 Substitute: 1.5 mg ÷ 0.5 mg/tablet

🔷 Calculate: 1.5 ÷ 0.5 = 3 tablets

🔷 Round to nearest whole number: already 3

Answer 9

Correct Answers:

mcg

Rationale :

🎀mcg is the metric abbreviation for microgram, a metric unit of weight used in medication dosing.

🎀Metric units of weight include mg, mcg, g, and kg, and mcg fits this system.

🎀This abbreviation is used internationally for precise medication calculation and dosing safety.

🎀 lb — pound is an imperial unit, not metric.

🎀oz — ounce is also imperial, not metric.

🎀mL — milliliter is a metric unit of volume, not weight.

Answer 10

Correct Answers:

1

Rationale :

🔵 Weight (kg):

146.7 lb × 0.45 = 66.015 kg

🔵 Dose (mg):

7.5 mg/kg × 66.015 kg = 495.1125 mg

🔵 Available:

500 mg per tablet

🔵 Tablets to give:

495.1125 mg ÷ 500 mg/tablet = 0.99 tablet ≈ 1 tablet (rounded to nearest whole number)
