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
T3 and T4 are thyroid hormones. While it’s important to monitor these levels in a patient on propylthiouracil therapy, they are not the most concerning lab value.
Choice B rationale
The white blood cell count should be the nurse’s primary concern. Propylthiouracil can cause agranulocytosis, a serious condition characterized by a decrease in the number of white blood cells, which can lead to infection.
Choice C rationale
Hemoglobin and hematocrit levels are important to monitor, but they are not the most concerning lab value in this context.
Choice D rationale
While it’s important to monitor platelet count in a patient on propylthiouracil therapy, it’s not the most concerning lab value.
Correct Answer is C
Explanation
Choice A rationale
While aromatherapy sprays can provide a calming environment, there is limited evidence to suggest that they can effectively reduce chemotherapy-induced nausea and vomiting.
Choice B rationale
Physical activity like a brisk walk outside can be beneficial for overall health, but it may not directly help in reducing nausea and vomiting caused by chemotherapy.
Choice C rationale
Avoiding well-seasoned, spicy, and fatty foods can help reduce nausea and vomiting during chemotherapy. These types of foods can irritate the stomach and make nausea worse.
Choice D rationale
Drinking a warm glass of milk may not be helpful in reducing chemotherapy-induced nausea and vomiting. In fact, dairy products can sometimes exacerbate nausea.
