Correct Answer: A

Rationale: The correct answer is A because the patient in cardiogenic shock with a cardiac output of 2.0 L/min is experiencing a life-threatening condition that requires immediate evaluation. Cardiogenic shock indicates poor cardiac function, which can lead to multi-organ failure. Monitoring cardiac output is crucial in managing these patients. Choice B is incorrect because a pulmonary artery systolic pressure of 20 mm Hg is within normal range and does not indicate an immediate life-threatening condition. Choice C is incorrect because a CVP of 6 mm Hg in a hypovolemic patient may indicate volume depletion, but it is not as urgent as the patient in cardiogenic shock. Choice D is incorrect because a PAOP of 10 mm Hg is within normal range and does not suggest an immediate critical condition.

Correct Answer: A

Rationale: The correct answer is A because providing postmortem care to a dying patient is a task that can be safely delegated to an LPN/LVN. This includes tasks such as preparing the body, cleaning, and positioning after death. LPNs/LVNs are trained and competent in performing these duties under the supervision of a registered nurse or physician. Choices B, C, and D are incorrect because they involve critical thinking, assessment, and teaching skills that are typically within the scope of practice of a registered nurse. Encouraging family members to talk with the patient, determining assessment frequency, and educating about signs of approaching death require a higher level of nursing judgment and expertise, which is beyond the scope of an LPN/LVN's role.

Correct Answer: C

Rationale: The correct answer is C because the healthcare surrogate should base decisions on recommendations of the physician and healthcare team who have the expertise to provide medical advice. They are best positioned to understand the patient's condition and treatment options. Personal beliefs (A) may not align with medical best practices. Family and friends' recommendations (B) may not be informed by medical knowledge. Wishes previously expressed by the patient (D) are important but may need to be interpreted in the context of the current medical situation, which healthcare professionals can provide.

Correct Answer: C

Rationale: The correct answer is C: Anxiety about unfinished business. The patient's desire to settle issues with their siblings before death indicates a concern about unresolved matters. This response aligns with the concept of psychosocial responses to death, specifically the need for closure and resolution. Restlessness (choice A) may not necessarily indicate a specific focus on unfinished business. Yearning and protest (choice B) typically refer to the initial stages of grief, not specifically related to settling unresolved issues. Fear of the meaninglessness of one's life (choice D) is more existential and philosophical, whereas the patient's focus here is on addressing specific issues with their siblings.

Correct Answer: D

Rationale: The presence of a bruit over the thyroid indicates increased blood flow, characteristic of hyperthyroidism. This excess blood flow is due to the hypermetabolic state in hyperthyroidism, leading to turbulent blood flow and the audible bruit. A bruit is not typically associated with hypothyroidism, thyroid cysts, or thyroid cancer, as these conditions do not cause increased blood flow. Therefore, the correct interpretation is hyperthyroidism.
