A nurse is preparing to administer heparin 7,500 units subcutaneous. Available is heparin 10,000 units/mL. How many ml. should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["0.75"]

To calculate the volume of heparin (in milliliters) to administer, you can use the following formula:

Volume (mL) = Desired dose (units) / Concentration (units/mL)

In this case, the desired dose is 7,500 units, and the concentration is 10,000 units/mL.

Volume (mL) = 7,500 units / 10,000 units/mL

Volume (mL) = 0.75 mL

So, the nurse should administer 0.75 mL of heparin.

Correct Answer is ["300"]

Explanation

To calculate how many milligrams (mg) of guaifenesin the client is taking with each dose, you can use the following steps:
Determine the volume of the client's dose. The client is taking 1 tablespoon (Tbsp) of guaifenesin oral solution.
1 Tbsp is approximately equal to 15 mL.
Determine the concentration of guaifenesin in the oral solution, which is 100 mg/5 mL.
Calculate the amount of guaifenesin in the client's dose:
Amount (mg) = (Volume of dose in mL / Concentration in mg/mL)
Amount (mg) = (15 mL / 5 mg/mL) = 3 doses of 100 mg each
So, the client is taking 300 mg of guaifenesin with each dose.

Correct Answer is ["0.71"]

Explanation

To calculate how many milliliters (mL) of the reconstituted medication to administer, you need to determine the desired dose and then divide it by the concentration of the reconstituted solution.

The label indicates that each vial, when reconstituted, contains ceftriaxone 350 mg/mL.

The desired dose is 250 mg.

So, you can use the following formula:

Volume to administer (mL) = Desired dose (mg) / Concentration of the reconstituted solution (mg/mL)

Volume to administer (mL) = 250 mg / 350 mg/mL

Volume to administer (mL) = 0.7143 mL (rounded to the nearest hundredth)

Therefore, the nurse should administer approximately 0.71 mL of the reconstituted ceftriaxone solution.
