Correct Answer: B

Rationale: In patients with leukemia, severe fatigue is a common symptom due to factors such as anemia, the disease process itself, and the effects of treatments like chemotherapy. The most appropriate intervention is to schedule frequent rest periods to help manage fatigue while encouraging a balance between rest and activity. This approach allows the patient to conserve energy for essential tasks and prevent exhaustion, without promoting complete inactivity, which can lead to deconditioning.

Correct Answer: A

Rationale: The client's symptoms of nausea, flank pain, and muscle cramps are suggestive of tumor lysis syndrome (TLS), a potentially life-threatening complication of chemotherapy in which cancer cells break down rapidly, releasing large amounts of intracellular components into the bloodstream. This leads to imbalances in electrolytes (elevated potassium, phosphate, and uric acid levels, with low calcium levels), which can cause severe metabolic disturbances, including kidney damage, arrhythmias, and muscle cramps. Checking serum electrolytes and uric acid levels is crucial for diagnosing and managing TLS early, preventing further complications.

Correct Answer: B

Rationale: Before any invasive procedure, such as placing a catheter to deliver chemotherapy beads into a liver tumor, it is essential to ensure that informed consent has been obtained from the client. This is a legal and ethical requirement that ensures the client understands the procedure, its risks, benefits, and alternatives. Ensuring that the signed consent is on the chart is the most important action the nurse can take before the procedure, as the procedure cannot legally proceed without it.

Correct Answer: B

Rationale: Difficulty swallowing (dysphagia) following radiation therapy to the neck area is a significant concern because it can indicate serious complications such as esophageal stricture, inflammation, or damage to the surrounding tissues, including the esophagus. This can lead to malnutrition, dehydration, or aspiration, all of which require prompt intervention. Radiation therapy can cause irritation and scarring in the esophageal and throat tissues, which may progressively worsen if not treated. Therefore, dysphagia should be addressed immediately to prevent further complications.
