Question

A nurse is preparing to administer prednisolone 2 mg/kg/day PO divided in equal doses every 12 hr to a toddler who has acute asthma and weighs 26lb. Available is prednisolone syrup 15 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer 1

Correct Answers:

3.9

Rationale :

🔸 Weight conversion:

✔️26 lb ÷ 2.2 = 11.82 kg

🔸 Total daily dose:

✔️ 2 mg/kg × 11.82 kg = 23.64 mg/day

🔸 Dose per 12 hr (divided BID):

✔️ 23.64 mg ÷ 2 = 11.82 mg

🔸 Volume to administer:

✔️ (11.82 mg × 5 mL) ÷ 15 mg = 3.94 (rounding off)

👉🏻= 3.9 mL

Answer 6

Correct Answers:

1

Rationale :

Formula:Dose per dose = (mg/kg/day × weight in kg) ÷ number of doses

Tablets per dose = Dose per dose ÷ tablet strength

Given:

🔻 Weight = 86 lb = 39.1 kg

🔻 Daily dose = 25 mg/kg/day × 39.1 kg = 977.5 mg/day

🔻 Doses per day = 3 (every 8 hr)

🔻 Dose per 8 hr = 977.5 ÷ 3 = 325.8 mg

🔻 Tablet strength = 325 mg

Calculation:

🔻 Tablets per dose = 325.8 ÷ 325 = 1

Answer 7

Correct Answers:

63

Rationale :

✔️ Rate (mL/hr) = Total volume ÷ Time (hr)

Given:

⩥ Total volume = 250 mL

⩥ Time = 4 hr

⩥ Step 1: Apply the formula

⩥ 250 mL ÷ 4 hr = 62.5

⩥ Step 2: Round to nearest whole number

⩥ 62.5 (rounding off)

👉🏻= 63 mL/hr

Answer 8

Correct Answers:

42

Rationale :

Formula:Rate (mL/hr) = Total volume ÷ Time (hr)

Given:

◇ Total volume = 250 mL

◇ Time = 6 hr

Calculation:

◇ 250 ÷ 6 = 41.6 (rounding off)
