Correct Answer: C

Rationale: After an open hemicolectomy (surgical removal of part of the colon), monitoring the surgical wound for signs of dehiscence (wound reopening) is a critical nursing priority. Dehiscence is a serious postoperative complication that can occur if the surgical site does not heal properly. Regular wound assessments every 4 hours allow the nurse to identify early signs of complications, such as redness, swelling, increased drainage, or separation of the wound edges. Early detection is key to preventing further complications, such as infection or evisceration (protrusion of abdominal organs through the wound).

Correct Answer: C

Rationale: Superior vena cava syndrome (SVCS) occurs when the superior vena cava, the large vein that carries blood from the upper body to the heart, becomes compressed or obstructed, often by a tumor or enlarged lymph nodes, typically in cancers like lung cancer or lymphoma. The obstruction leads to increased venous pressure and reduced blood flow, resulting in swelling and edema in areas drained by the superior vena cava. Periorbital edema (swelling around the eyes) is one of the earliest signs of SVCS. This occurs because the impaired venous return causes fluid to accumulate in the soft tissues of the face, especially around the eyes. As the condition progresses, facial swelling can worsen, and other symptoms develop.

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: D

Rationale: Acute Lymphocytic Leukemia (ALL) is a type of cancer where immature lymphocytes (a type of white blood cell) proliferate uncontrollably in the bone marrow. This leads to a reduction in the production of platelets, leukocytes, and erythrocytes, causing symptoms such as fatigue, anemia, bleeding tendencies, and increased susceptibility to infection. In ALL, leukemic cell infiltration into other organs is common, which can manifest as severe headaches (due to central nervous system involvement), vomiting, and testicular pain (due to infiltration of leukemic cells into the testes). These are hallmark signs of ALL, especially in younger patients.

Correct Answer: D

Rationale: While chemotherapy does affect normal, healthy cells-particularly those that divide rapidly-it is not "more likely" to kill normal cells compared to cancer cells. Chemotherapy targets rapidly dividing cells, which includes both cancer cells and some normal cells (like those in hair follicles, the gastrointestinal tract, and bone marrow). However, its primary goal is to kill cancer cells, and its effects on normal cells are a side effect, not the main function. Therefore, the statement that chemotherapy is "more likely" to kill normal cells is inaccurate and indicates a need for further teaching.
