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 ["0.8 "]

Explanation

Given:

Desired dose of heparin: 8,000 units
Available strength of heparin injection: 10,000 units/mL

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

Volume (mL) = 8,000 units / 10,000 units/mL Volume (mL) = 0.8 mL

So, the nurse should administer 0.8 mL of heparin.

Correct Answer is ["100 "]

Explanation

Given:

Insulin glargine concentration: 100 units/mL
Total volume of insulin in the vial: 10 mL
Dose of insulin glargine per day: 10 units

Calculation:

First, let's find out how many total units are in the vial:

Total units = Concentration (units/mL) × Volume (mL) Total units = 100 units/mL × 10 mL

Total units = 1000 units

Now, let's find out how many doses can be obtained from the total units in the vial: Number of doses = Total units / Dose per day

Number of doses = 1000 units / 10 units/day Number of doses = 100 doses

So, the vial contains approximately 100 doses of insulin glargine.
