Correct Answer: B

Rationale: Diltiazem is a calcium channel blocker that can lead to bradycardia as an adverse effect due to its negative chronotropic and dromotropic effects on the heart. The nurse should monitor the client's heart rate regularly to detect any signs of bradycardia and take appropriate actions if necessary.

Correct Answer: B

Rationale: The healthcare professional should monitor the client for ototoxicity when receiving carboplatin. Ototoxicity is a known serious adverse effect associated with this medication, characterized by damage to the inner ear structures leading to hearing loss or balance issues. Monitoring for hearing changes and balance problems is crucial to detect ototoxicity early and prevent further complications.

Correct Answer: B

Rationale: The nurse should instruct the client to report fever as it can be an indication of an infection, which is a potential complication of rituximab therapy. Monitoring for fever is crucial to detect early signs of infection and prevent complications.

Correct Answer: C

Rationale: The client's symptoms indicate circulatory overload, which can occur during blood transfusions. Furosemide, a loop diuretic, is commonly prescribed in such cases to help relieve manifestations of circulatory overload by promoting diuresis and reducing fluid volume. Epinephrine is used for severe allergic reactions, lorazepam for anxiety or seizures, and diphenhydramine for mild allergic reactions or as a sedative.

Correct Answer: C

Rationale: It is crucial to withhold all opioids, including Morphine, if the client's respiratory rate is 12/min or less, and promptly inform the healthcare provider. Respiratory depression is a significant adverse effect of opioids, and administering them when the respiratory rate is already compromised can further suppress breathing, leading to potentially life-threatening complications.
