Correct Answer: B

Rationale: The correct answer is B: Take them to a private area for initial explanations. This response is the best because it allows the nurse to address the family's concerns in a private and controlled environment. It promotes effective communication and enables the family to express their emotions and receive information without distractions. Choice A is incorrect because asking the family to leave may escalate the situation and not address their needs. Choice C is inappropriate as paging security to remove the family can worsen the family's distress and hinder communication. Choice D is not ideal as leaving the family alone may lead to misunderstandings and increased anxiety. Overall, choice B is the most therapeutic and effective approach in this situation.

Correct Answer: B

Rationale: The correct answer is B: Hypovolemia. When the ventilator settings are adjusted to treat hypoxemia by increasing FiO2 and PEEP, it can lead to increased oxygenation but also potentially decrease venous return to the heart, causing a decrease in blood pressure. This decrease in blood pressure is most likely due to hypovolemia, as the increased PEEP can increase intrathoracic pressure, reducing venous return and preload, leading to a decrease in cardiac output and subsequent decrease in blood pressure. This choice is the most likely cause as the other options (A: Decrease in cardiac output, C: Increase in venous return, D: Oxygen toxicity) do not directly correlate with the changes in ventilator settings described in the question.

Correct Answer: A

Rationale: The correct answer is A because a cooler right hand may indicate compromised circulation, potentially due to arterial occlusion or clot formation. This could lead to inadequate perfusion and tissue damage. Immediate action is needed to assess and address the cause. Choice B is incorrect because a MAP of 77 mm Hg is within the normal range for most patients and does not require immediate action. Choice C is incorrect as delivering 3 mL of flush solution per hour is an appropriate rate and does not indicate a need for immediate action. Choice D is incorrect as the flush bag and tubing being changed 3 days ago does not necessarily indicate an immediate issue with the arterial line function.

Correct Answer: B

Rationale: The correct answer is B because in a home hospice program, it is essential for the nurse to provide holistic care that includes addressing the patient's emotional and psychological needs. Encouraging the patient to discuss past life events and their meaning can help them process emotions, find closure, and improve their quality of life. This approach aligns with the principles of palliative care, which focus on enhancing comfort and well-being. Choice A is incorrect because discussing cancer risk factors and lifestyle modifications may not be relevant or beneficial for a patient in a hospice program. Choice C is incorrect because chemotherapy and radiation are typically not part of hospice care, which focuses on comfort rather than curative treatments. Choice D is incorrect because a thorough head-to-toe assessment multiple times a week may not be necessary or appropriate for a patient in a hospice program.

Correct Answer: C

Rationale: The correct answer is C because asking the family to state their biggest concern clarifies the nurse's understanding of the current family needs. This step allows the nurse to assess the specific areas where the family may require support or assistance, leading to more tailored interventions. By identifying the primary concern, the nurse can better address the family's emotional, informational, or practical needs. Choice A is incorrect because the question is not solely about active listening; it serves a deeper purpose of assessment. Choice B is incorrect as the question goes beyond validating knowledge to understanding emotional and practical needs. Choice D is incorrect because the question focuses on identifying concerns rather than defining the degree of understanding.
