A nurse is caring for a patient receiving chemotherapy.
Which of the following interventions should the nurse include in the patient's plan of care?

Choice A rationale

Weight loss over several weeks, while a concerning symptom in a cancer patient, is not the most specific or immediate finding indicative of superior vena cava syndrome (SVCS). Weight loss is a general symptom of malignancy (cancer cachexia) due to increased metabolic demands, catabolism, and reduced caloric intake. SVCS involves specific obstruction of venous return to the heart, leading to distinct signs and symptoms related to impaired blood flow from the head, neck, and upper extremities.

Choice B rationale

Facial swelling and edema is the most concerning and classic finding indicative of superior vena cava syndrome. Obstruction of the superior vena cava, often by an extrinsic tumor compression (e.g., lung cancer, lymphoma), impairs venous drainage from the head, neck, and upper extremities. This leads to increased hydrostatic pressure in these areas, resulting in visible facial edema, periorbital edema, and swelling of the neck and arms.

Choice C rationale

Increased appetite is generally not associated with superior vena cava syndrome or advanced cancer. Patients with cancer, especially those with advanced disease or undergoing treatment, frequently experience anorexia, early satiety, and altered taste, leading to decreased appetite and weight loss. SVCS itself does not directly influence appetite regulation, though the underlying malignancy might contribute to systemic symptoms that affect appetite negatively.

Choice D rationale

Mild nausea and vomiting, while possible symptoms in a cancer patient due to various factors (e.g., chemotherapy, pain medication, hypercalcemia), are not specifically indicative of superior vena cava syndrome. SVCS is characterized by signs and symptoms related to venous congestion in the upper body. Nausea and vomiting are non-specific gastrointestinal symptoms and do not directly arise from the pathophysiology of superior vena cava obstruction.

Choice A rationale

Decreasing fluid intake can lead to dehydration, which exacerbates fatigue by impairing cellular metabolic processes and reducing blood volume, thus decreasing oxygen and nutrient delivery to tissues. Optimal hydration is crucial for maintaining cellular function, electrolyte balance, and overall energy levels, as it supports efficient metabolic waste removal and nutrient transport, thereby mitigating fatigue associated with radiation therapy. Normal fluid intake for an adult is typically 2.5-3.5 liters per day.

Choice B rationale

Planning 4-5 hours of daytime rest can disrupt normal nocturnal sleep patterns, leading to fragmented sleep and an exacerbation of fatigue. Excessive daytime napping can alter the circadian rhythm, making it difficult to achieve restorative sleep at night, which is essential for cellular repair, hormone regulation, and energy restoration. Short, strategic naps of 20-30 minutes are generally more beneficial to alleviate fatigue without interfering with nighttime sleep.

Choice C rationale

Avoiding between-meal snacks can lead to prolonged periods without caloric intake, resulting in hypoglycemia and depleted energy reserves, which significantly contribute to fatigue. Regular, small, nutrient-dense snacks help maintain stable blood glucose levels, providing a continuous supply of energy for metabolic processes and preventing the energy troughs that intensify fatigue. Adequate nutrition is vital for cellular energy production during radiation therapy.

Choice D rationale

Prioritizing activities from important to least important allows the client to conserve energy for essential tasks, preventing overexertion and managing fatigue effectively. This strategy, known as energy conservation, involves pacing activities, delegating non-essential tasks, and incorporating rest periods, thereby optimizing energy utilization and minimizing the physiological and psychological burden of fatigue commonly experienced during radiation therapy.
