A nurse is preparing to administer epoetin 7,000 units subcutaneous for management of anemia related to chronic kidney disease. Available is 10,000 units/mL. How many mL should the nurse administer?
(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 ["0.7"]

To calculate the amount of epoetin to administer, we can use the following formula:

Amount to administer (mL) = (Desired dose (units) / Available dose (units/mL))

Plugging in the given values:

Amount to administer (mL) = (7,000 units / 10,000 units/mL)

Now, let's solve for the amount to administer:

Amount to administer (mL) = (7,000 / 10,000) = 0.7 mL

So, the nurse should administer 0.7 mL of epoetin subcutaneously for the management of anemia related to chronic kidney disease.

Correct Answer is C

Explanation

Choice A reason: Diet cola PO is not an appropriate recommendation for a client with a blood glucose of 30, because diet cola does not contain any sugar and will not raise the blood glucose level. Moreover, the client is lethargic and unable to follow commands, which means they may have difficulty swallowing and may aspirate the liquid.

Choice B reason: Dextrose 50% IV is a potential recommendation for a client with a blood glucose of 30, because it can rapidly increase the blood glucose level and reverse the symptoms of hypoglycemia. However, the nurse is unable to get an IV line started on the client, which makes this option impossible.

Choice C reason: Glucagon IM is the best recommendation for a client with a blood glucose of 30, because it can stimulate the liver to release glucose into the bloodstream and raise the blood glucose level. Glucagon can be given intramuscularly or subcutaneously, which does not require an IV access. Glucagon is usually given as an emergency treatment for severe hypoglycemia when the client is unconscious or unable to swallow.

Choice D reason: Insulin glargine SQ is not an appropriate recommendation for a client with a blood glucose of 30, because insulin glargine is a long-acting insulin that lowers the blood glucose level. Giving insulin to a client with hypoglycemia can worsen their condition and cause coma or death. ⁹

Correct Answer is ["1.1"]

Explanation

To calculate the amount of cefazolin that the nurse should add to the 50 mL of 0.9% sodium chloride, we can use the following steps:

Calculate the amount of cefazolin needed to prepare the solution:

  • The concentration to be achieved is 225 mg/mL.
  • The required dose is 250 mg.

Calculate the volume of cefazolin needed:

  • 250 mg ÷ 225 mg/mL = 1.111... mL
  • Rounded to the nearest tenth, the nurse should add 1.1 mL of cefazolin to the 50 mL of 0.9% sodium chloride.

Therefore, the nurse should add 1.1 mL of cefazolin to the 50 mL of 0.9% sodium chloride to prepare the solution for IV administration.
