A nurse is preparing to administer darbepoetin 0.45 mcg/kg subcutaneous once weekly to a client who weighs 198 lb. The amount available is Darbepoetin 300 mcg/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 ["0.1 mL"]

To calculate the dose of darbepoetin that the nurse should administer, we can follow these steps:

Convert the client's weight from pounds to kilograms:

198 lb ÷ 2.2 = 89.82 kg (rounded to two decimal places)

Calculate the dose of darbepoetin:

0.45 mcg/kg × 89.82 kg = 40.41 mcg

Determine the volume of darbepoetin needed using the available concentration:

40.41 mcg ÷ 300 mcg/mL = 0.1347 mL

Rounding to the nearest tenth, the nurse should administer 0.1 mL of darbepoetin subcutaneously once weekly.

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 ["8 mL"]

Explanation

To calculate the amount of phenytoin oral suspension to administer, we can use the following formula:

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

Plugging in the given values:

Amount to administer (mL) = (200 mg / 125 mg/5 mL)

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

Amount to administer (mL) = (200 mg / 125 mg/5 mL) = (200 / 125) 5 = 8

So, the nurse should administer 8 mL of phenytoin oral suspension via the gastrostomy tube.
