For a client with polycythemia vera, how can the nurse help decrease the risk for thrombus formation?

Correct Answer: B

Rationale: The correct answer is B: Help the client don thromboembolic stocking or support hose during waking hours. This intervention helps decrease the risk for thrombus formation in polycythemia vera by promoting venous return and preventing blood pooling in the lower extremities. Compression stockings improve circulation and reduce the risk of blood clots. Isometric exercises (choice A) may increase blood pressure and heart rate, potentially worsening the risk of thrombus formation. Drinking excess fluid (choice C) can lead to hypervolemia and increase the risk of clotting. Resting immediately if chest pain develops (choice D) is important but does not directly address the prevention of thrombus formation in polycythemia vera.

Correct Answer: D

Rationale: The correct answer is D: Chronic ache or pain. Persistent cough and chronic ache or pain are both common warning signs of cancer. Chronic pain can be a symptom of various types of cancer, signaling the presence of a tumor or cancerous growth. It is important for the client to seek medical evaluation to rule out any underlying serious condition. A: Persistent nausea is not typically considered a common warning sign of cancer. While it can be a symptom in certain types of cancer or due to treatment side effects, it is not as prominent as chronic ache or pain. B: Indigestion is a common symptom that can be caused by various non-cancer-related issues such as dietary habits, stress, or gastrointestinal disorders. It is not typically considered a direct warning sign of cancer. C: Rash is generally not a common warning sign of cancer. Rashes are more commonly associated with skin conditions, allergic reactions, or infections rather than being an indicator of cancer.

Correct Answer: B

Rationale: The correct answer is B: Bence jones protein in the urine. In multiple myeloma, abnormal plasma cells produce excess monoclonal immunoglobulins, including Bence Jones proteins, which can be detected in the urine. This is a hallmark finding in multiple myeloma diagnosis. A: Incorrect. Serum creatinine levels are typically not affected in multiple myeloma. C: Incorrect. Hypercalcemia, not hypocalcemia, is commonly seen in multiple myeloma due to bone destruction. D: Incorrect. Multiple myeloma often presents with high serum protein levels, not low levels.

Correct Answer: D

Rationale: The correct answer is D: Sigmoidoscopy. Sigmoidoscopy is a direct visualization procedure that allows for examination of the lower part of the colon and rectum, where colorectal cancer commonly occurs. This procedure can help identify any abnormal growths or polyps that may indicate cancer. Stool hematest (A) detects blood in stool but does not confirm colorectal cancer. Abdominal CT (B) provides imaging of the abdomen but may not definitively diagnose colorectal cancer. CEA scan (C) measures a tumor marker associated with colorectal cancer but is not a definitive diagnostic test. Thus, sigmoidoscopy is the most appropriate diagnostic study for confirming colorectal cancer.

Correct Answer: D

Rationale: The correct answer is D - Shallow breathing and increasing lethargy. This could indicate a potential complication such as respiratory distress or postoperative infection. Shallow breathing may suggest respiratory compromise, while increasing lethargy could be a sign of systemic infection or inadequate oxygenation. A: Abdominal pain is common postoperatively and can be managed with pain medication. B: Serous drainage from the incision is normal and expected in the early postoperative period. C: Hypoactive bowel sounds are common after abdominal surgery due to anesthesia and manipulation of the bowel; it typically resolves as the patient recovers. In summary, the other options are common postoperative findings, while shallow breathing and increasing lethargy are concerning signs that require immediate attention.
