Correct Answer: C

Rationale: An improved albumin level is the best indicator of improved nutritional status after TPN. Albumin is a key protein that reflects the body's overall nutritional status and is commonly used to assess nutritional health. Choices A, B, and D are not as reliable indicators of improved nutritional status. Choice A may not accurately reflect nutritional improvement as it could be influenced by factors other than nutrition. Choice B may indicate fluid retention or loss rather than true nutritional improvement. Choice D, hemoglobin level, is more related to anemia and oxygen-carrying capacity of the blood, rather than nutritional status.

Correct Answer: A

Rationale: Postoperative pain is commonly caused by the surgical incision and muscle tension. The correct answer is A. Surgical incisions cause tissue damage, triggering pain responses. Muscle tension can result from factors like positioning during surgery or guarding due to pain. Managing postoperative pain caused by surgical incisions and muscle tension involves the use of analgesics to alleviate discomfort. Choices B, C, and D are incorrect. Nerve damage and wound complications may also cause pain but are not as common as surgical incisions and muscle tension. Hypotension and respiratory issues are not direct causes of postoperative pain. Infection at the incision site can lead to pain, but it is a specific complication rather than a common cause of postoperative pain.

Correct Answer: B

Rationale: The correct answer is B: 'Demonstrate assertiveness.' For clients with dependent personality disorder, assertiveness training is crucial as it helps them become more independent and develop the skills to express their own needs and preferences effectively. Choice A ('Limit social interactions') is incorrect because promoting healthy social interactions is important for individuals with this disorder to build confidence and reduce dependency. Choice C ('Follow a rigid schedule') is incorrect as overly rigid schedules may exacerbate feelings of helplessness and dependence. Choice D ('Perform deep breathing exercises') is not directly related to addressing the core issues of dependent personality disorder, which primarily involve developing self-reliance and assertiveness.

Correct Answer: D

Rationale: The correct answer is to investigate for signs of infection when caring for a client diagnosed with delirium. Infections can frequently cause or worsen delirium. While investigating medication history, sensory deficits, and cognitive functioning may be important in the overall care of the client, when prioritizing, the nurse should first rule out or address potential infections due to their significant impact on delirium.
