Correct Answer: C

Rationale: The correct answer is C because a pulmonary artery occlusion pressure of 25 mm Hg indicates possible fluid overload or cardiac issue requiring urgent evaluation. This value is high, suggesting increased pressure in the left side of the heart. Additionally, the oxygen saturation of 89% on 3 L of oxygen indicates potential respiratory compromise. This patient needs immediate assessment and intervention to prevent worsening of their condition. Choice A is incorrect as a central venous pressure of 6 mm Hg is within normal limits, and the urine output is adequate. Choice B is incorrect as a BP of 110/60 mm Hg is acceptable, and a slightly dampened arterial waveform is not an immediate concern. Choice D is incorrect as a pulmonary artery pressure of 25/10 mm Hg is within normal range, and an oxygen saturation of 94% on 2 L of oxygen is acceptable.

Correct Answer: C

Rationale: The correct answer is C because guided imagery involves using the patient's imagination to focus on pleasant sensory experiences. This helps distract the patient from the current situation and reduces anxiety. By remembering tactile sensations of a pleasant experience, the patient can create a calming mental image. Choice A is incorrect because guided imagery does not require an external focus point like a picture. Choice B is incorrect because the technique does not involve staring at a focus point but rather focusing on mental images. Choice D is incorrect because while relaxation is beneficial, guided imagery specifically focuses on visualization of positive experiences to reduce anxiety.

Correct Answer: A

Rationale: The correct answer is A because it respects the patient's right to privacy while also acknowledging the family's presence. By asking family members if they wish to remain in the room, the nurse allows them to make an informed decision based on their comfort level. This approach fosters open communication and shows respect for the family's emotions. Choice B is incorrect because abruptly removing family members can increase their distress and feelings of powerlessness. Choice C is incorrect as it places the burden of support solely on a staff member, potentially isolating the family from the situation. Choice D is incorrect as it assumes family members should stay without considering their preferences or emotional well-being.

Correct Answer: C

Rationale: The correct answer is C: Provide for oxygen administration. The first intervention for hypoxemia is to increase oxygen levels to improve oxygen saturation in the blood. Oxygen administration can be achieved through various devices such as nasal cannula, face mask, or non-rebreather mask. This intervention helps to increase the oxygen supply to the patient's tissues and organs, addressing the underlying cause of hypoxemia. Calling for emergency intubation (choice A) is not the first step unless the patient's condition deteriorates. Obtaining an order for BiPAP (choice B) may be beneficial in some cases but is not the initial intervention for hypoxemia. Suctioning secretions (choice D) may be necessary if airway obstruction is present but is not the first step in addressing hypoxemia.

Correct Answer: C

Rationale: The correct answer is C because the patient's expressed beliefs and wishes regarding quality of life are personal factors that directly influence the ethical dilemma. This factor reflects the individual's values, beliefs, and preferences, which are essential in making ethical decisions that respect the patient's autonomy. Considering the patient's beliefs helps healthcare professionals navigate complex ethical situations by aligning the care provided with the patient's values. Choices A, B, and D do not directly relate to personal factors but rather focus on hospital policies, physiological symptoms, and the provider's perspective, respectively. Personal factors are crucial in ethical decision-making as they center on the patient's autonomy and preferences.
