Correct Answer: B

Rationale: Following a liver biopsy, the nurse should instruct the client to lie on the right side to promote hemostasis. This position helps apply pressure to the biopsy site, reducing the risk of bleeding. Instructing the client to lie on the left side (Choice A) would not provide the same benefit. Increasing fluid intake (Choice C) is generally beneficial post-procedure to prevent dehydration and promote healing. Decreasing fluid intake (Choice D) is not advisable as it can lead to dehydration and potential complications.

Correct Answer: B

Rationale: Tuberculosis is spread through small droplets, measuring less than 5 microns, which can remain airborne for extended periods. The nurse should place a client with TB under airborne precautions to prevent the transmission of the disease. Choice A, contact precautions, are used for diseases that spread by direct or indirect contact. Choice C, droplet precautions, are for diseases transmitted by large droplets. Choice D, protective environment, is used for clients who have compromised immune systems.

Correct Answer: B

Rationale: The correct answer is B: Fatigue. A client with early HIV infection can be asymptomatic or experience symptoms like viral infections, such as fever, rash, and fatigue. Fatigue is a common early manifestation of HIV infection due to the body's immune response. Stomatitis (choice A) is more commonly associated with oral health issues or infections. Wasting syndrome (choice C) and lipodystrophy (choice D) are more advanced manifestations seen in later stages of HIV infection, characterized by severe weight loss and changes in body fat distribution, respectively.

Correct Answer: A

Rationale: The correct instruction the nurse should provide is that the medication can cause the client's urine to turn a dark color, which is a harmless effect of carbidopa/levodopa. This is due to the metabolites of levodopa. Immediate relief is not expected after taking the medication because it may take weeks to months to achieve the full therapeutic effect. Taking the medication with a high-protein food is not recommended as protein can interfere with the absorption of levodopa. Skipping a dose of the medication if the client experiences dizziness is incorrect as dizziness may be a side effect of the medication, and doses should not be skipped without consulting a healthcare provider.

Correct Answer: A

Rationale: A distended, board-like abdomen is a concerning sign indicating the possibility of a ruptured appendix and peritonitis, which are medical emergencies. Reporting this finding immediately is crucial for prompt intervention. Choice B, an elevated WBC count, could indicate infection but is not as urgent as the risk of a ruptured appendix. Choice C, rebound tenderness over McBurney's point, is a classic sign of appendicitis but does not indicate an immediate threat like a possible rupture. Choice D, a slightly elevated temperature, is a nonspecific finding and not as critical as the risk of peritonitis associated with a distended, board-like abdomen.
