Correct Answer: A

Rationale: Fatigue is a common adverse effect of zidovudine due to its impact on bone marrow, leading to anemia. Zidovudine is known to suppress bone marrow function, resulting in decreased production of red blood cells and subsequently causing fatigue due to anemia. Monitoring for fatigue is essential to ensure early detection and management of this adverse effect.

Correct Answer: C

Rationale: Atenolol, a beta-blocker, can lead to bradycardia as an adverse effect due to its mechanism of action. The nurse should advise the client to monitor their pulse regularly, as a significant decrease may indicate bradycardia, a condition characterized by a slow heart rate.

Correct Answer: A

Rationale: Bone pain is a known adverse effect of Filgrastim, which is dose-related. By assessing for bone pain, the nurse can monitor for this common side effect. Acetaminophen and, if necessary, an opioid analgesic can be used to manage the bone pain associated with Filgrastim. Assessing for right lower quadrant pain, crackles in the bases of the lungs, or heart murmurs would not directly relate to the adverse effects of Filgrastim in a client with chronic Neutropenia.

Correct Answer: C

Rationale: The nurse should monitor the client for neutropenia when receiving hydroxyurea. Neutropenia is a common adverse effect caused by bone marrow suppression. It is essential to assess the client's white blood cell count regularly to detect neutropenia early and prevent complications such as infections.

Correct Answer: C

Rationale: Atenolol is a beta-blocker that can cause bradycardia as an adverse effect due to its mechanism of action in slowing down the heart rate. The nurse should instruct the client to monitor their pulse regularly and report any significant decreases to prevent complications related to bradycardia.
