Correct Answer is ["1.8 "]

Explanation

Given:

Desired dose of ceftriaxone: 75 mg/kg/day
Child's weight: 37 lb
Available strength of ceftriaxone after reconstitution: 350 mg/mL

First, convert the child's weight from pounds to kilograms: 37 lb ÷ 2.20462 = 16.78 kg (rounded to the nearest hundredth)

The total daily dose of ceftriaxone:

Total daily dose = Desired dose × Child's weight

Total daily dose = 75 mg/kg/day × 16.78 kg Total daily dose ≈ 1258.5 mg

Since the total daily dose is to be divided into two equal doses, each dose would be:

Each dose = Total daily dose / Number of doses per day Each dose = 1258.5 mg / 2

Each dose = 629.25 mg

The milliliters of ceftriaxone correspond to each dose:

Volume (mL) = Dose / Concentration

Volume (mL) = 629.25 mg / 350 mg/mL Volume (mL) ≈ 1.8 mL

So, the nurse should administer approximately 1.8 mL of ceftriaxone per dose.

Correct Answer is ["20 "]

Explanation

Given:

Desired dose of megestrol: 800 mg
Available strength of megestrol suspension: 40 mg/mL

First, find out how many milliliters of megestrol suspension correspond to the desired dose: Volume (mL) = Desired dose / Concentration

Volume (mL) = 800 mg / 40 mg/mL Volume (mL) = 20 mL

So, the nurse should administer 20 mL of megestrol suspension.
