Rationale: The correct answer is B. Scopolamine is not a pain medication; it is commonly used to prevent nausea and vomiting, particularly in surgical settings. It works on the central nervous system to help control these symptoms, not to relieve pain. Therefore, it is important for the nurse to explain to the client that the medication is not intended to relieve pain but rather to manage other specific symptoms. Checking the correct placement of the patch is also important to ensure proper administration, but addressing the misconception about the medication's purpose is the priority in this scenario.

Rationale: The correct answer is A: Hypertension. Epoetin alfa can lead to hypertension as an adverse effect because it stimulates increased red blood cell production. This can result in elevated blood pressure levels, requiring careful monitoring by the nurse to prevent complications.

Correct Answer: A

Rationale: The correct answer is A: Bone marrow suppression. Methotrexate, commonly used in rheumatoid arthritis, can lead to bone marrow suppression, reducing the production of blood cells and increasing the risk of infection. Monitoring for signs of anemia, leukopenia, and thrombocytopenia is crucial to detect bone marrow suppression early and prevent complications.
