A nurse is preparing to administer hydrocortisone 150 mg via IV bolus. Available is hydrocortisone 50 mg/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 ["3"]

To calculate the amount of hydrocortisone 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) = (150 mg / 50 mg/mL)

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

Amount to administer (mL) = (150 / 50) = 3 mL

So, the nurse should administer 3 mL of hydrocortisone via IV bolus.

Correct Answer is D

Explanation

Choice A reason: This choice is incorrect because sulfa allergy is not a priority assessment for the nurse to make prior to giving nifedipine. Sulfa allergy is a hypersensitivity reaction to drugs that contain sulfonamide, such as antibiotics, diuretics, or antidiabetic agents. Sulfa allergy can cause symptoms such as rash, itching, fever, or anaphylaxis. Nifedipine does not contain sulfonamide and does not cross-react with sulfa drugs. The nurse should ask the client about any drug allergies and document them, but sulfa allergy is not relevant to nifedipine.

Choice B reason: This choice is incorrect because aPTT is not a priority assessment for the nurse to make prior to giving nifedipine. aPTT stands for activated partial thromboplastin time, which is a measure of how long it takes the blood to clot. It is used to monitor the effect of anticoagulant drugs, such as heparin, that prevent blood clots. Nifedipine does not affect the blood clotting time and does not interact with anticoagulant drugs. The nurse should check the aPTT only if the client is taking anticoagulant drugs and has signs of bleeding or clotting.

Choice C reason: This choice is incorrect because hemoglobin is not a priority assessment for the nurse to make prior to giving nifedipine. Hemoglobin is a protein in the red blood cells that carries oxygen to the tissues and organs of the body. Hemoglobin levels can be affected by conditions such as anemia, dehydration, or blood loss. Nifedipine does not affect the hemoglobin levels or the oxygen delivery. The nurse should monitor the hemoglobin levels and the signs of anemia, such as fatigue, pallor, or shortness of breath, but they are not related to nifedipine.

Choice D reason: This choice is correct because blood pressure is the priority assessment for the nurse to make prior to giving nifedipine. Nifedipine is a calcium channel blocker that lowers blood pressure and relaxes the blood vessels. It is used to treat conditions such as hypertension, angina, and Raynaud's phenomenon. However, nifedipine can cause side effects such as hypotension (low blood pressure), dizziness, headache, flushing, and edema (swelling). The nurse should check the client's blood pressure before giving nifedipine and withhold the dose if the blood pressure is too low. The nurse should also monitor the client's blood pressure and the signs of hypotension, such as fainting, weakness, or chest pain.

Correct Answer is ["31"]

Explanation

To calculate the IV flow rate in drops per minute (gtt/min), we can use the following steps:

Calculate the total number of minutes for the infusion:

8 hours × 60 minutes/hour = 480 minutes

Determine the total number of drops needed for the infusion:

The total volume to be infused is 1000 mL.

The drop factor is 15 gtt/mL.

1000 mL × 15 gtt/mL = 15000 gtt

Calculate the IV flow rate in drops per minute:

15000 gtt ÷ 480 min ≈ 31 gtt/min

Rounding to the nearest whole number, the nurse should set the IV flow rate to deliver 31 gtt/min.
