Before administering amphotericin B to a patient, what is the most crucial step a nurse should take?
Attach a continuous pulse oximetry probe to the patient’s finger.
Set the IV pump to deliver the medication over a span of 30 minutes.
Connect the patient to a continuous cardiac monitor.
Evaluate the patient’s sodium and calcium levels.
The Correct Answer is D
Choice A rationale
While continuous pulse oximetry can provide useful information about a patient’s oxygen saturation levels, it is not the most crucial step before administering amphotericin B. Amphotericin B is an antifungal medication used to treat serious, potentially life-threatening fungal infections. It does not directly affect oxygen saturation levels.
Choice B rationale
The rate at which amphotericin B is administered can be important, as the medication must be given slowly through an IV infusion, which can take from 2 to 6 hours to complete. However, setting the IV pump to deliver the medication over a specific span of time is not the most crucial step before administration.
Choice C rationale
Continuous cardiac monitoring can be important in certain situations, but it is not the most crucial step before administering amphotericin B. While amphotericin B can cause some side effects related to the heart, such as changes in heart rate or blood pressure, these are not typically the primary concerns before administration.
Choice D rationale
Evaluating the patient’s sodium and calcium levels is the most crucial step before administering amphotericin B. Amphotericin B can cause changes in electrolyte levels, including sodium and calcium. Monitoring these levels can help prevent potential complications, making this the most crucial step before administration.

Correct Answer is B
Explanation
Choice A rationale
Hypermagnesemia, or high levels of magnesium in the blood, is not a common side effect of proton pump inhibitors. These medications do not contain magnesium and do not cause the body to produce more magnesium.
Choice B rationale
Long-term use of proton pump inhibitors may contribute to osteoporosis. Some studies have suggested that these medications can interfere with calcium absorption, potentially leading to bone loss and an increased risk of fractures.
Choice C rationale
While some people may experience diarrhea as a side effect of proton pump inhibitors, it is not one of the most common side effects.
Choice D rationale
Drowsiness is not a typical side effect of proton pump inhibitors. These medications work by reducing the amount of acid produced in the stomach, but they do not typically affect alertness or energy levels.
Correct Answer is D
Explanation
Choice A rationale
It is not advisable for a patient to discontinue radioactive iodine therapy at any time if they feel uncomfortable. Radioactive iodine therapy is a safe and effective treatment for certain types of thyroid cancer. Discontinuing the medication without medical advice could lead to ineffective treatment.
Choice B rationale
Increasing the consumption of iodine-rich foods is not necessary when a patient is prescribed radioactive iodine. The body’s thyroid cells absorb the radioactive iodine, which then destroys the cells. Consuming additional iodine would not enhance this process.
Choice C rationale
Using a straw to drink the medication is not necessary. Radioactive iodine is usually given in pill form, not as a liquid. Therefore, there is no risk of it staining the patient’s teeth.
Choice D rationale
This statement is correct. After a total thyroidectomy, the patient will no longer have thyroid tissue that can produce thyroid hormones. Therefore, the radioactive iodine will not eliminate the need for thyroid hormone replacement.
