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 A
Explanation
Choice A rationale
Corticosteroids, like the ones the client has been receiving for severe bronchitis, can cause an increase in glucose levels. This is because corticosteroids can stimulate the liver to release extra glucose and can also make body tissues less sensitive to insulin.
Choice B rationale
Type 2 diabetes does not convert to type 1 diabetes. These are two distinct conditions with different causes.
Choice C rationale
While illness and stress can make the body’s tissues less sensitive to insulin, leading to higher blood glucose levels, the client’s bronchitis symptoms have resolved. Therefore, this is not the most likely reason for the increase in glucose levels.
Choice D rationale
Antibiotics do not typically cause an increase in glucose levels. Therefore, this is not the most likely reason for the increase in glucose levels.
Correct Answer is B
Explanation
Choice A rationale
Peripheral edema is not a common side effect of stopping steroids early. Peripheral edema is often associated with conditions such as heart failure, liver disease, or kidney disease.
Choice B rationale
Low blood pressure is a common side effect when a person stops taking steroids like prednisone abruptly. Prednisone is a glucocorticoid, a type of steroid that works to mimic the effects of cortisol, a hormone that the adrenal glands produce. The body uses cortisol to regulate the heart rate and blood pressure. When a person takes prednisone for longer than a few weeks, the body reduces the amount of cortisol it makes. When a person suddenly stops taking prednisone, the body cannot immediately produce enough cortisol to make up for the missing drug. This results in withdrawal symptoms, including low blood pressure.
Choice C rationale
Hyperglycemia, or high blood sugar, is not typically a withdrawal symptom of stopping steroids early. While long-term use of steroids can lead to increased blood sugar levels, stopping the medication does not typically cause hyperglycemia.
Choice D rationale
Weight loss can be a symptom of steroid withdrawal, but it is not the most immediate or common symptom that would be anticipated in a client who stopped taking their prescribed steroids early. More common symptoms include fatigue, joint pain, and low blood pressure.
