Answer 2

Correct Answers:

94

Rationale :

Formula:

Rate (mL/hr) = Total Volume ÷ Time (hr)

Given:

⩥ Volume = 750 mL

⩥ Time = 8 hr

Calculation:

⩥ 750 ÷ 8 = 93.75 mL/hr →

✔️ = 94 mL/hr

Answer 3

Correct Answers:

7.5

Rationale :

Formula:

Volume = (Desired Dose ÷ Available Dose) × Volume per mL

Given:

⩥ Desired = 20 mEq

⩥ Available = 40 mEq/15 mL

Calculation:

⩥ (20 ÷ 40) × 15 = 0.5 × 15

✔️= 7.5 mL

Answer 4

Correct Answers:

120

Rationale :

Formula:

Flow rate (gtt/min) = (Volume × Drop factor) ÷ Time (min)

Given:

⩥ Volume = 120 mL/hr

⩥ Drop factor = 60 gtt/mL

⩥ Time = 60 min/hr

Calculation:

⩥ (120 × 60) ÷ 60

✔️ = 120 gtt/min

Answer 5

Correct Answers:

2

Rationale :

Formula:

Flow rate (gtt/min) = (Volume × Drop factor) ÷ Time (min)

Given:

⩥ Volume = 200 mL

⩥ Time = 24 hr = 1440 min

⩥ Drop factor = 15 gtt/mL

Calculation:

⩥ (200 × 15) ÷ 1440 = 3000 ÷ 1440 = 2.08 →

✔️ = 2 gtt/min

Answer 6

Correct Answers:

136.4

Rationale :

Formula:

Weight in kg = Weight in lb ÷ 2.2

Given:

⩥ 300 lb

Calculation:

⩥ 300 ÷ 2.2

✔️ = 136.4 kg

Answer 7

Correct Answers:

6

Rationale :

Formula:

Volume = Dose ÷ Concentration

Given:

⩥ Dose = 12 mg

⩥ Available = 2 mg/mL

Calculation:

⩥ 12 ÷ 2

✔️= 6 mL

Answer 8

Correct Answers:

1

Rationale :

Formula:

g = mg ÷ 1000

Given:

⩥ 1000 mg

Calculation:

⩥ 1000 ÷ 1000

✔️ = 1 g

Answer 9

Correct Answers:

125

Rationale :

Formula:

Rate (mL/hr) = Volume ÷ Time (hr)

Given:

⩥ 3000 mL over 24 hr

Calculation:

⩥ 3000 ÷ 24

✔️ = 125 mL/hr

Answer 10

Correct Answers:

50

Rationale :

Formula:

Flow rate (gtt/min) = (Volume × Drop factor) ÷ Time (min)

Given:

⩥ Volume = 400 mL

⩥ Time = 8 hr = 480 min

⩥ Drop factor = 60 gtt/mL

Calculation:

⩥ (400 × 60) ÷ 480 = 24000 ÷ 480

✔️= 50 gtt/min
