Question

A client must receive a tube-feeding of Vita-sure, 240 ml. in 45 minutes. The calibration of the tubing is 15 drops per milliliter. Calculate the flow rate in milliliters per hour.

Answer 1

Correct Answers:

320

Rationale :

✍🏽240 mL in 45 min

✍🏽Formula

♦️mL/hr = mL ÷ hours

♦️45 min = 45/60 hr = 0.75 hr

♦️mL/hr = 240 ÷ 0.75

✅ 320 mL/hr

Answer 2

Correct Answers:

88

Rationale :

✔️ 0.9% NaCl 350 mL in 4 hr; DF = 60 gtt/mL

✔️Formula

➡️gtt/min = (mL ÷ min) × drop factor

➡️4 hr = 4 × 60 = 240 min

➡️mL/min = 350 ÷ 240 = 1.4583 mL/min

➡️gtt/min = 1.4583 × 60

📌 87.5 gtt/min

📌88 gtt/min

Answer 3

Correct Answers:

610

Rationale :

✏️500 mL; flow = 27 gtt/min; DF = 20 gtt/mL

✏️Formula:

mL/min = gtt/min ÷ DF
time (min) = total mL ÷ mL/min
mL/min = 27 ÷ 20 = 1.35 mL/min
time (min) = 500 ÷ 1.35 = 370.37 min
370.37 min = 360 min + 10.37 min

✅ 6 hours and 10 minutes

Answer 4

Correct Answers:

10

Rationale :

✔️Order 10 mg daily; concentration = 1 mg/mL

✔️Formula

➡️mL = ordered dose (mg) ÷ concentration (mg/mL)

➡️mL = 10 mg ÷ (1 mg/mL)

♦️10 mL

Answer 5

Correct Answers:

168

Rationale :

💠30 mg/kg IM q12h; weight = 2,800 g = 2.8 kg

💠Formula

mg/dose = (mg/kg) × kg
mg/day = mg/dose × doses/day

💠 mg/dose = 30 × 2.8 = 84 mg

💠q12h → 2 doses/day

💠mg/day = 84 × 2

✅ 168 mg in 24 hours

Answer 6

Correct Answers:

0.5

Rationale :

➡️Order gr 1/4; available gr 1/2 per tablet

➡️Formula

📌tablets = ordered dose ÷ dose per tablet

📌 tablets = (1/4) ÷ (1/2) = (1/4) × (2/1) = 2/4

📌0.5 tablet

Answer 7

Correct Answers:

0.8

Rationale :

✍🏽Order 4,000 units; supply 10,000 units/2 mL

✍🏽Formula

⏺️mL = ordered units ÷ (units per mL)

⏺️units per mL = 10,000 ÷ 2 = 5,000 units/mL

⏺️mL = 4,000 ÷ 5,000

✅ 0.8 mL per dose

Answer 8

Correct Answers:

140

Rationale :

✔️ 2 mcg/kg/min; weight = 154 lb

✔️Formula

♦️mcg/min = (mcg/kg/min) × kg

♦️kg = 154 ÷ 2.2 = 70 kg

♦️mcg/min = 2 × 70

✅140 mcg/min

Answer 9

Correct Answers:

12.6

Rationale :

Weight = 56 kg
Concentration = 400 mg in 500 mL D5W
Order = 3 mcg/kg/min

♦️Formula:

Concentration (mcg/mL) = (mg × 1,000 mcg/mg) ÷ mL
Dose (mcg/min) = (mcg/kg/min) × kg
mL/min = dose (mcg/min) ÷ concentration (mcg/mL)
mL/hr = mL/min × 60

Concentration = (400 mg × 1,000) ÷ 500 mL = 400,000 mcg ÷ 500 = 800 mcg/mL
Dose = 3 mcg/kg/min × 56 kg = 168 mcg/min
mL/min = 168 ÷ 800 = 0.21 mL/min
mL/hr = 0.21 × 60

♦️12.6 mL/hr

Answer 10

Correct Answers:

2

Rationale :

✏️Dose = 30 mL every 6 hr

✏️Conversion: 1 tbsp = 15 mL

✏️Formula

➡️tbsp = mL ÷ 15

➡️tbsp = 30 ÷ 15

📌2 tablespoon(s) per dose
