A male client is scheduled for a transsphenoidal hypophysectomy to remove a pituitary tumor. Preoperatively, the nurse should assess for potential complications by doing which of the following?

Correct Answer: D

Rationale: Rationale: Performing capillary glucose testing every 4 hours is crucial preoperatively for a transsphenoidal hypophysectomy because the surgery can cause alterations in glucose levels due to stress response and potential pituitary dysfunction. Monitoring glucose levels helps prevent complications like hypoglycemia or hyperglycemia. Testing for ketones in the urine (A) is not specific to glucose levels. Testing urine specific gravity (B) is not as relevant for monitoring glucose levels. Checking temperature every 4 hours (C) is important but not directly related to potential complications from the surgery.

Correct Answer: D

Rationale: The correct answer is D because putting on the elastic stockings before getting out of bed in the morning helps prevent blood pooling in the lower extremities. This statement indicates the client understands the importance of wearing the stockings to promote circulation. Choice A is incorrect because the client should follow the prescribed duration for wearing the stockings, not wait for the physician's instruction to remove them. Choice B is incorrect as wearing stockings while sleeping may not be necessary unless specified by the healthcare provider. Choice C is incorrect as removing the stockings for a prolonged period every four hours may not be recommended as consistent wear is typically more beneficial for circulation.

Correct Answer: B

Rationale: The correct answer is B: "I will call my doctor if Stacy has persistent vomiting and diarrhea". Rationale: 1. Persistent vomiting and diarrhea are common side effects of chemotherapy that can lead to dehydration and other complications. 2. Contacting the physician in this case shows understanding of the need for immediate medical attention. 3. Prompt communication with the doctor can help in managing these side effects effectively and prevent further complications. Summary: A: Difficulty in sleeping is a common side effect of chemotherapy but does not require immediate medical attention. C: Irritability and unhappiness are subjective symptoms and may not indicate a serious medical issue. D: Continued hair loss is a known side effect of chemotherapy but does not require immediate medical attention unless excessive.

Correct Answer: D

Rationale: The correct answer is D: Elevated serum aminotransferase. In liver cirrhosis, liver cells are damaged, causing release of aminotransferase enzymes into the bloodstream. Elevated levels of serum aminotransferase, such as ALT and AST, indicate liver damage. Decreased red blood cell count (A) is not specific to liver cirrhosis. Decreased serum acid phosphate level (B) is not a typical indicator of liver cirrhosis. Elevated white blood cell count (C) is more commonly associated with infection or inflammation, not liver cirrhosis.

Correct Answer: D

Rationale: Rationale for Correct Answer D: Furosemide (Lasix) inhibits sodium and water reabsorption in the loop of Henle, leading to diuresis and decreased blood volume, thus reducing blood pressure. This mechanism is specific to loop diuretics like furosemide. Option A is incorrect as furosemide acts on the kidneys, not peripheral blood vessels. Option B is incorrect as furosemide does not directly affect sympathetic cardioacceleration. Option C is incorrect as furosemide does not target angiotensin-converting enzymes, which are related to the renin-angiotensin-aldosterone system.
