A nurse is preparing to administer heparin 10,000 units subcutaneous every 8 hr. Available is heparin injection 20,000 units/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 and Explanation

The Correct Answer is ["0.5"]

1. Heparin Dosage and Concentration:

Heparin dosage per dose: 10,000 units

Heparin concentration: 20,000 units/mL (available injection)

2. Volume Calculation:

We can use the following formula to find the volume to administer:

Volume (mL) = Dosage (units) / Concentration (units/mL)

Volume (mL) = 10,000 units / 20,000 units/mL

3. Rounding the Answer:

Round the calculated volume to the nearest tenth of a milliliter.

Volume (mL) = 0.5 mL (rounded to one decimal place)

Therefore, the nurse should administer 0.5 mL of heparin injection per dose.

Correct Answer is ["0.5"]

Explanation

To find the number of tablets,

we divide the total dosage in mg by the strength of each tablet in mg.

Let’s do the calculation:

Numberoftablets=StrengthofeachtabletinmgTotaldosageinmg=40mg/tablet20mg=0.5tablet

So, the nurse should administer 0.5 tablet of quinapril.

Correct Answer is ["0.75"]

Explanation

The nurse should administer 0.75 mL of methylprednisolone acetate suspension for injection. Here's the breakdown:

Dosage: 60 mg of methylprednisolone acetate

Concentration: 80 mg/mL (milligrams per milliliter) of methylprednisolone acetate suspension

Volume calculation:

We can find the volume to administer using the following formula:

Volume (mL) = Dosage (mg) / Concentration (mg/mL)

Plugging in the values:

Volume (mL) = 60 mg / 80 mg/mL

Rounding the answer:

Round the calculated volume (0.75) to the nearest hundredth of a milliliter.

Therefore, the nurse should administer 0.75 mL of methylprednisolone acetate suspension for injection.
