A nurse is discussing the TNM staging system with a client.
Which of the following statements about the TNM classification is correct?

Choice A rationale

Diarrhea is not a primary or life-threatening complication associated with medications that stimulate platelet production, such as oprelvekin or thrombopoietin receptor agonists. While gastrointestinal upset can occur with many medications, it does not represent the significant physiological risks targeted by nursing surveillance in this specific therapy. The focus of monitoring for these agents is centered on fluid balance and vascular integrity, as these drugs significantly impact intravascular osmotic pressure and the coagulation cascade through increased cellular production.

Choice B rationale

Nausea and vomiting are common side effects of many systemic therapies but are not considered the most critical or specific complications of platelet-stimulating agents. These symptoms are generally managed with antiemetics and do not typically require the cessation of therapy. When managing a patient on oprelvekin, the nurse prioritizes monitoring for systemic inflammatory responses and fluid retention over mild gastrointestinal distress, as the latter does not usually lead to long-term morbidity or acute cardiovascular collapse in this context.

Choice C rationale

Stimulating the production of platelets, or thrombopoiesis, carries a significant risk of inducing a prothrombotic state where blood clots may form. When the platelet count rises rapidly or exceeds the normal range of 150,000 to 450,000 cells/uL, the risk for deep vein thrombosis, pulmonary embolism, or myocardial infarction increases. The nurse must assess for signs of vascular occlusion, including localized edema, redness, and sudden chest pain, as the increased cell density enhances blood viscosity and clotting.

Choice D rationale

Bone fractures are not a typical complication of platelet-stimulating therapy. While some colony-stimulating factors can cause bone pain due to the expansion of bone marrow, they do not generally lead to acute structural failure or pathological fractures. Bone marrow stimulation is a physiological process that occurs within the medullary cavity and, while uncomfortable, does not degrade the mineral density of the cortical bone. Nursing care focuses on pain management rather than fall precautions related to skeletal fragility in these patients.

Choice E rationale

Pulmonary edema is a severe complication specifically linked to oprelvekin therapy due to its tendency to cause sodium and water retention. The resulting expansion of plasma volume increases hydrostatic pressure within the pulmonary capillaries, leading to fluid shifting into the alveoli. The nurse must monitor for dyspnea, crackles upon auscultation, and decreased oxygen saturation. This fluid shift can lead to acute respiratory distress syndrome, making frequent cardiovascular and respiratory assessments essential for early detection of fluid overload.

Choice A rationale

Fatigue is a universal side effect associated with both radiation therapy and chemotherapy. In radiation, it results from the energy required for cellular repair and the accumulation of metabolic waste from cell death. In chemotherapy, it is often linked to anemia, systemic inflammation, and the cytotoxic effects on healthy tissues. Because both treatments involve systemic or localized cellular destruction and require significant physiological recovery, fatigue is a common finding shared by both modalities.

Choice B rationale

Night sweats are typically associated with the underlying malignancy itself, such as lymphoma or advanced pancreatic cancer, rather than being a specific side effect of radiation or chemotherapy. While systemic reactions can occur, night sweats are more frequently a symptom of the body's inflammatory response to the tumor or an indication of infection. They are not classified as a standard, predictable side effect of either treatment modality in the same way that cytopenias or enteritis are.

Choice C rationale

Weight loss is a common finding for both radiation and chemotherapy. Radiation to the abdominal area causes gastrointestinal upset and malabsorption, while chemotherapy induces systemic nausea, vomiting, and alterations in taste. Both treatments can lead to a state of cachexia where the body breaks down muscle and fat stores faster than they can be replenished. Nutritional support is a primary concern for patients undergoing these therapies to combat treatment-induced weight loss.

Choice D rationale

Pale skin, or pallor, is associated with both radiation and chemotherapy due to their impact on the bone marrow. Chemotherapy is systemically myelosuppressive, leading to decreased red blood cell production and anemia. While radiation is localized, if the treatment field includes bone-marrow-producing areas like the pelvis or spine, it can also contribute to lower hemoglobin levels. Anemia reduces the oxygen-carrying capacity of the blood, resulting in the visible paleness of the skin and mucous membranes.
