Question 2 of 5
The client diagnosed with peripheral arterial disease (PAD) has a new prescription for clopidogrel. What information should the nurse include when teaching the client about this medication?
Correct Answer: A

Question 3 of 5
The client who has been taking glipizide for 6 months reports to the nurse that his urine has become darker since starting the medication. What is the nurse's first action?
Correct Answer: D
Rationale: Glipizide and other sulfonylureas can affect liver function, and dark urine can indicate potential liver issues, such as bilirubinuria. Reviewing liver function studies would provide critical information to assess if the change in urine color is related to liver dysfunction.
