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 ["2 "]

Explanation

Given:

Desired dose of levothyroxine: 0.05 mg
Available strength of levothyroxine tablets: 25 mcg

First, convert the desired dose from milligrams to micrograms:

0.05 mg = 50 mcg

Number of tablets = Desired dose / Strength per tablet

Number of tablets = 50 mcg / 25 mcg/tablet Number of tablets = 2 tablets

So, the nurse should plan to administer 2 tablets of levothyroxine.

Correct Answer is ["1.1 "]

Explanation

Given:

Desired dose of cefazolin: 250 mg
Reconstituted concentration of cefazolin: 225 mg/mL

First, calculate the volume of the reconstituted solution needed to administer the desired dose:

Volume (mL) = Desired dose / Concentration

Volume (mL) = 250 mg / 225 mg/mL Volume (mL) ≈ 1.11 mL

So, the nurse should administer approximately 1.1 mL of the reconstituted cefazolin solution.
