Hint : Convert the client’s weight to kilograms, multiply by 15 mg/kg, then use the ratio 250 mg = 5 mL to find how many mL to give.

Correct Answers:

  • 13.2

Rationale :

1️⃣ Convert pounds to kilograms

Use your preferred factor: 1 lb ≈ 0.45 kg

98 lb × 0.45 = 44.1 kg

2️⃣ Find the prescribed dose in mg

Order: 15 mg/kg

15 mg × 44.1 kg = 661.5 mg

3️⃣ Use the concentration to find mL

Available: 250 mg in 5 mL

That’s:

250 mg ÷ 5 mL = 50 mg/mL

Now:

661.5 mg ÷ 50 mg/mL = 13.23 mL

4️⃣ Round to the nearest tenth

13.23 mL → 13.2 mL

Hint : Find units per mL, then divide 1,200 units/hr by that number.

Correct Answers:

  • 24

Rationale :

1️⃣ Find the concentration

25,000 units ÷ 500 mL = 50 units/mL

2️⃣ Calculate mL/hr

1,200 units/hr ÷ 50 units/mL = 24 mL/hr

✅ Final Answer: 24 mL/hr

Hint : Change both fractions to the same denominator before subtracting.

Correct Answers:

  • False

Rationale :

Step 1: Convert to denominator 30

89/10 = (89 × 3) ÷ 30 = 267/30

32/3 = (32 × 10) ÷ 30 = 320/30

Step 2: Subtract

267/30 - 320/30 = (267 - 320) ÷ 30 = -53/30

So:

89/10 - 32/3 = -53/30, not 57/30

Hint : First change mg to mcg, then divide the dose ordered by the dose available per tablet.

Correct Answers:

  • 0.5

Rationale :

Order: 500 mcg

Available: 1 mg scored tablet

Convert mg → mcg:

1 mg = 1000 mcg

Now calculate tablets:

500 mcg ÷ 1000 mcg = 0.5 tablet
