The nurse is preparing an infusion of amphotericin B for a patient who has a severe fungal infection. Which intervention is appropriate regarding the potential adverse effects of amphotericin B?
- A. Discontinuing the infusion immediately if fever, chills, or nausea occur
- B. Gradually increasing the infusion rate until the expected adverse effects occur
- C. If fever, chills, or nausea occur during the infusion, administering medications to treat the symptoms
- D. Before beginning the infusion, administering an antipyretic and an antiemetic drug
Correct Answer: D
Rationale: Almost all patients given the drug intravenously experience fever, chills, hypotension, tachycardia, malaise, muscle and joint pain, anorexia, nausea and vomiting, and headache. For this reason, pretreatment with an antipyretic (acetaminophen), antihistamines, and antiemetics may be conducted to decrease the severity of the infusion-related reaction.
A patient is taking nystatin oral lozenges to treat an oral candidiasis infection resulting from inhaled corticosteroid therapy for asthma. Which instruction by the nurse is appropriate?

- B. Let the lozenges dissolve slowly and completely in your mouth without chewing it
- C. Rinse your mouth with water before taking the inhaler
- D. Rinse your mouth with mouthwash after taking the inhaler
Correct Answer: B

Patients taking an inhaled corticosteroid must rinse their mouths with water thoroughly after taking the inhaler.
