Question 2 of 5
A patient is taking digoxin (Lanoxin) and a loop diuretic daily. When the nurse enters the room with the morning medications, the patient states, I am seeing a funny yellow color around the lights. What is the nurse™s next action?
Correct Answer: A
Rationale: The patient's statement about seeing a funny yellow color around the lights is indicative of potential digoxin toxicity, as digoxin can cause visual disturbances, such as changes in color vision. The nurse should assess the patient for other symptoms of digoxin toxicity, which may include nausea, vomiting, confusion, and changes in heart rate. It is important to evaluate the patient's condition further to determine the appropriate course of action, including the need for further evaluation and potentially withholding the next dose of digoxin.

Question 5 of 5
A nurse is giving medicinal instructions to a female client receiving leflunomide (Arava). Which of the following is an appropriate instruction with the use of the medication?
Correct Answer: A
Rationale: Leflunomide is teratogenic and can cause severe birth defects. Women of childbearing age must use effective contraception during treatment and for a period after discontinuation. Breastfeeding is contraindicated due to the risk of harm to the infant. Cholestyramine is used to accelerate the elimination of leflunomide in case of toxicity, not to lessen side effects. Improvement in symptoms typically takes weeks, not days.
