Correct Answer: D

Rationale: Step-by-step rationale for Answer D being correct: 1. PA catheter measures PA pressures. 2. PAWP reflects left atrial pressure. 3. Correct placement shows typical PAWP tracing. 4. PA pressure waveform (A) is not specific to PAWP. 5. Systemic arterial pressure tracing (B) is unrelated. 6. Systemic vascular resistance tracing (C) is not monitored by PA catheter.

Correct Answer: C

Rationale: The correct answer is C: Respiratory acidosis may occur if the patient continues at these ventilator settings. Respiratory acidosis happens when the lungs cannot remove enough of the carbon dioxide (CO2) produced by the body. In this case, the low respiratory rate of 14 breaths/min may not be sufficient to adequately remove CO2, leading to its accumulation in the blood. This results in a decrease in blood pH, causing respiratory acidosis. Summary of other choices: A: Metabolic acidosis - Not the correct answer as the ventilator settings are more likely to affect the respiratory system rather than the metabolic system. B: Metabolic alkalosis - Not the correct answer as the ventilator settings are not related to causing an increase in blood pH, which is characteristic of metabolic alkalosis. D: Respiratory alkalosis - Not the correct answer as the low respiratory rate would not lead to excessive elimination of CO2, causing alkalosis.

Correct Answer: B

Rationale: The correct answer is B: Cardiac output (CO) of 4 L/min. In this scenario, the patient is presenting with signs of pulmonary congestion and hypoxemia, indicating possible cardiogenic pulmonary edema. As the cardiac output is a key indicator of how well the heart is functioning and delivering blood to the body, a low cardiac output can lead to inadequate tissue perfusion and worsen the patient's condition. Therefore, immediate action is required to address the low cardiac output to improve tissue perfusion and oxygenation. Choices A, C, and D are incorrect as they do not directly address the primary concern of inadequate cardiac output in this patient. Cardiac index, pulmonary vascular resistance, and systemic vascular resistance are important parameters to monitor, but in this case, the priority is to address the low cardiac output to improve the patient's condition.

Correct Answer: C

Rationale: The correct answer is C: Moral distress. In this scenario, the nurse is experiencing conflicting moral values between the decision made for the patient and their own beliefs. This internal conflict leads to moral distress, a common response when healthcare professionals feel unable to act in accordance with their ethical beliefs. This can lead to emotional turmoil, frustration, and moral residue. A: A sense of abandonment is incorrect because the nurse is still caring for the patient, so there is no physical abandonment. B: Increased family stress is incorrect as the nurse's internal conflict does not directly impact family stress. D: A sense of negligence is incorrect as negligence implies failure to provide proper care, which is not the case here.

Correct Answer: A

Rationale: The correct answer is A: One chronic and one acute illness. This is because Type 2 diabetes mellitus is a chronic condition, while influenza is an acute illness. The nurse should develop goals addressing the management and control of the chronic condition (diabetes) as well as the treatment and recovery from the acute illness (influenza). This approach ensures comprehensive care that considers both the long-term management of the chronic illness and the immediate needs related to the acute illness. Choices B, C, and D are incorrect because they do not address the combination of chronic and acute illnesses presented in the scenario. Choice B focuses solely on two acute illnesses, which overlooks the ongoing management required for the chronic condition. Choice C combines an acute and an infectious illness, but fails to account for the chronic illness component. Choice D involves two chronic illnesses, neglecting the immediate care needed for the acute illness.
