Hint : 💡Convert mcg → mg first.

Correct Answers:

  • 0.55


Rationale :

💠 Step 1: Convert mcg to mg

1 mg = 1000 mcg

275 mcg ÷ 1000 = 0.275 mg

💠 Step 2: Identify available concentration

0.5 mg per 1 mL

💠 Step 3: Use the dosage formula

mL to administer = Desired dose ÷ Dose on hand × Quantity

💠 Step 4: Substitute values

mL = 0.275 mg ÷ 0.5 mg × 1 mL

💠 Step 5: Calculate

mL = 0.55

💠 Step 6: Round to hundredths

0.55

Hint : 💡 First find mg per 1 mL.

Correct Answers:

  • 0.9


Rationale :

💠 Step 1: Identify ordered dose

225 mg

💠 Step 2: Identify available concentration

500 mg in 2 mL

💠 Step 3: Find mg per 1 mL

500 mg ÷ 2 mL = 250 mg per 1 mL

💠 Step 4: Use the dosage formula

mL to administer = Desired dose ÷ Dose per mL

💠 Step 5: Substitute values

mL = 225 mg ÷ 250 mg

💠 Step 6: Calculate

mL = 0.9

💠 Step 7: Round to tenths

0.9

Hint : 💡 Weight × mg/kg first.

Correct Answers:

  • 6.25


Rationale :

💠 Step 1: Calculate the ordered dose based on weight

10 mg/kg × 25 kg = 250 mg

💠 Step 2: Identify available concentration

200 mg per 5 mL

💠 Step 3: Find mg per 1 mL

200 mg ÷ 5 mL = 40 mg per 1 mL

💠 Step 4: Use the dosage formula

mL to administer = Desired dose ÷ Dose per mL

💠 Step 5: Substitute values

mL = 250 mg ÷ 40 mg

💠 Step 6: Calculate

mL = 6.25

💠 Step 7: Round to hundredths

6.25

✅ Final Answer: 6.25

Hint : 💡 Multiply first, then divide by 60.

Correct Answers:

  • 15


Rationale :

💠 Step 1: Write the formula for drops per minute

gtt/min = (mL/hr × drop factor) ÷ 60

💠 Step 2: Identify given values

mL/hr = 90

Drop factor = 10 gtt/mL

💠 Step 3: Substitute values into formula

gtt/min = (90 × 10) ÷ 60

💠 Step 4: Multiply numerator

90 × 10 = 900

💠 Step 5: Divide by 60 minutes

900 ÷ 60 = 15

💠 Step 6: Round to whole number

Hint : 💡Units ordered ÷ units per mL.

Correct Answers:

  • 0.55


Rationale :

💠 Step 1: Identify the ordered dose

5500 units

💠 Step 2: Identify available concentration

10,000 units per 1 mL

💠 Step 3: Use the dosage formula

mL to administer = Desired dose ÷ Dose on hand

💠 Step 4: Substitute values

mL = 5500 ÷ 10,000

💠 Step 5: Calculate

mL = 0.55

💠 Step 6: Round to hundredths and place leading zero

0.55

Hint : 💡 Divide ordered mg by mg per capsule.

Correct Answers:

  • 3


Rationale :

💠 Step 1: Identify the ordered dose

600 mg

💠 Step 2: Identify available strength per capsule

200 mg per 1 capsule

💠 Step 3: Use the dosage formula

Number of capsules = Desired dose ÷ Dose per capsule

💠 Step 4: Substitute values

Capsules = 600 mg ÷ 200 mg

💠 Step 5: Calculate

Capsules = 3

💠 Step 6: No rounding needed

Hint : 💡 Convert minutes to hours first.

Correct Answers:

  • 200


Rationale :

💠 Step 1: Identify total volume to infuse

100 mL

💠 Step 2: Identify infusion time in minutes

30 minutes

💠 Step 3: Convert minutes to hours

30 minutes ÷ 60 = 0.5 hours

💠 Step 4: Use IV pump rate formula

mL/hr = Total volume ÷ Time (hours)

💠 Step 5: Substitute values

mL/hr = 100 ÷ 0.5

💠 Step 6: Calculate

mL/hr = 200

💠 Step 7: No rounding needed

200

Hint : 💡 Find units/hr, then divide by units/mL.

Correct Answers:

  • 14.6


Rationale :

💠 Step 1: Calculate the ordered heparin dose per hour (units/hr)

18 units/kg/hr × 65 kg = 1170 units/hr

💠 Step 2: Calculate the concentration of the IV bag (units/mL)

20,000 units ÷ 250 mL = 80 units/mL

💠 Step 3: Convert ordered units/hr to mL/hr

mL/hr = (units/hr) ÷ (units/mL)

💠 Step 4: Substitute values

mL/hr = 1170 ÷ 80

💠 Step 5: Calculate

mL/hr = 14.625

💠 Step 6: Round to tenths

14.6

Hint : 💡 Check maximum dose before converting to mL.

Correct Answers:

  • 0.52


Rationale :

💠 Step 1: Calculate ordered bolus dose (units)

80 units/kg × 65 kg = 5200 units

💠 Step 2: Compare with maximum bolus

Maximum allowed = 10,000 units

5200 units is below maximum → use 5200 units

💠 Step 3: Identify available concentration

10,000 units per 1 mL

💠 Step 4: Use dosage formula

mL = Desired dose ÷ Dose on hand

💠 Step 5: Substitute values

mL = 5200 ÷ 10,000

💠 Step 6: Calculate

mL = 0.52

💠 Step 7: Round to hundredths and ensure leading zero

0.52
