A nurse is preparing to administer magnesium hydroxide 2.4 g PO daily. Available is magnesium hydroxide suspension 400 mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["30 "]

Given:

Desired dose of magnesium hydroxide: 2.4 g
Available strength of magnesium hydroxide suspension: 400 mg/5 mL

First, let's convert the desired dose from grams to milligrams:

2.4 g = 2400 mg

Now, let's find out how many milliliters of magnesium hydroxide suspension correspond to the desired dose:

Volume (mL) = Desired dose / Concentration

Volume (mL) = 2400 mg / 400 mg/5 mL Volume (mL) = (2400 mg * 5 mL) / 400 mg Volume (mL) = 30 mL

So, the nurse should administer 30 mL of magnesium hydroxide suspension.

Correct Answer is ["5000000"]

Explanation

1g= 1,000,000 mcg

5g= 5 *1,000,000

=5,000,000 mcg

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.
