Correct Answer: B

Rationale: The correct answer is B (200 cells/mm3 of blood) because a patient with HIV is considered to have AIDS when their CD4+ T-lymphocyte cell count drops below 200 cells/mm3. This threshold signifies a significant decrease in the immune system's ability to fight off infections and indicates progression to AIDS. Choice A (75 cells/mm3 of blood) is incorrect because this level is extremely low and would indicate severe immunosuppression, likely leading to AIDS much earlier than anticipated. Choice C (325 cells/mm3 of blood) and D (450 cells/mm3 of blood) are also incorrect as these levels are within the normal range or slightly lower, which would not meet the criteria for a diagnosis of AIDS.

Correct Answer: C

Rationale: The correct answer is C because assessing the patient's wound for dehiscence every 4 hours is crucial post hemicolectomy to monitor for any signs of wound complications, such as infection or tissue breakdown. This allows for early detection and intervention, promoting optimal wound healing and preventing potential complications. Choice A is incorrect as compartment syndrome is not a common complication after a hemicolectomy, and assessing for it hourly would be excessive and unnecessary. Choice B is incorrect as assessing fine motor skills is not a priority in the immediate postoperative period following a hemicolectomy. Choice D is incorrect as maintaining the patient's head of bed at 45 degrees or more is important for preventing respiratory complications, but it is not the top priority compared to wound assessment for dehiscence in this scenario.

Correct Answer: B

Rationale: The correct answer is B because assessing and promoting the patient's coping skills is essential in addressing the psychosocial needs of a patient with macular degeneration. By understanding how the patient is coping with the vision loss, the nurse can tailor interventions to support the patient effectively. This approach acknowledges the patient's emotional responses and helps them navigate the challenges associated with the condition. Choice A is incorrect as solely focusing on other senses may not address the psychological impact of vision loss. Choice C is incorrect as it dismisses the significant lifestyle changes the patient may experience. Choice D is incorrect as promoting hope for recovery may not be realistic in the case of irreversible conditions like macular degeneration.

Correct Answer: C

Rationale: The correct answer is C: Invasion of the uterine wall by endometrial tissue. Adenomyosis is a condition where endometrial tissue grows into the muscular wall of the uterus, causing symptoms like heavy menstrual bleeding and severe cramping. This process results in inflammation, thickening of the uterine wall, and can lead to enlargement of the uterus. Choice A: Loss of muscle tone in the vaginal wall is incorrect because adenomyosis does not involve the vaginal wall. Choice B: Excessive synthesis and release of unopposed estrogen is incorrect because although estrogen can contribute to the growth of endometrial tissue, it is not the primary pathophysiologic process in adenomyosis. Choice D: Proliferation of tumors in the uterine wall is incorrect because adenomyosis does not involve the growth of tumors, but rather the infiltration of endometrial tissue into the uterine muscle.

Correct Answer: B

Rationale: The correct answer is B because reflex incontinence with elevated blood pressure and pulse rate indicates a potentially urgent medical situation that requires immediate attention to address the underlying cause. This patient may be at risk for a serious medical event such as autonomic dysreflexia, which requires prompt intervention. Choice A is incorrect because urge incontinence does not pose an immediate threat to the patient's health compared to the urgent medical situation presented in choice B. Choice C is incorrect because while stool on the catheter tubing may indicate the need for intervention, it is not as time-sensitive as the situation presented in choice B. Choice D is incorrect because the patient who has just voided and needs a postvoid residual test does not have any urgent medical issues that require immediate attention compared to the patient with reflex incontinence and elevated vital signs.
