Correct Answer: B

Rationale: The correct answer is B: Temperature. Decreased ScvO2 in severe pancreatitis can be due to systemic inflammatory response leading to increased metabolic demand and decreased tissue oxygen delivery. Monitoring temperature helps assess for presence of infection or sepsis, which can further decrease tissue oxygenation. Lipase (A) is specific for pancreatitis diagnosis, not directly related to ScvO2. Urinary output (C) is important for assessing renal function, not directly related to ScvO2. Body mass index (D) does not provide information on tissue oxygenation status in this context.

Correct Answer: C

Rationale: Correct Answer: C - Regular insulin Rationale: 1. Insulin promotes cellular uptake of potassium. 2. When insulin is administered, it moves potassium from extracellular to intracellular space. 3. This decreases plasma potassium levels safely. 4. Other options do not directly lower potassium levels in the same manner. Summary of Other Choices: A: Sodium polystyrene sulfonate - exchanges sodium for potassium in the intestines, not reducing total body potassium. B: Sodium polystyrene sulfonate with sorbitol - similar to A, does not reduce total body potassium. D: Calcium gluconate - does not directly lower potassium levels, used for treating hyperkalemia-induced cardiac toxicity.

Correct Answer: B

Rationale: The correct answer is B: Equal bilateral breath sounds upon auscultation. This indicates proper placement of the endotracheal tube in the trachea, ensuring both lungs are being ventilated equally. Rationale: 1. Auscultation of air over the epigastrium (Choice A) is incorrect as it indicates esophageal intubation, not tracheal intubation. 2. Position above the carina verified by chest x-ray (Choice C) is incorrect as it does not confirm proper placement at the trachea. 3. Positive detection of carbon dioxide (CO2) (Choice D) is incorrect as it indicates the presence of exhaled CO2, but not necessarily proper placement in the trachea.

Correct Answer: D

Rationale: The correct action is D: Manually ventilate the patient with 100% oxygen. This is crucial to ensure adequate oxygenation and prevent hypoxia. Holding the ET tube can lead to extubation and airway compromise. Activating the rapid response team (A) may delay immediate intervention. Providing reassurance (B) is important but not the priority in this situation. Calling the health care provider (C) to reinsert the tube would also lead to a delay in providing essential respiratory support.

Correct Answer: C

Rationale: The correct answer is C: Multidisciplinary support. The Critical Care Family Assistance Program offers a range of professionals such as social workers, counselors, and financial advisors to provide holistic support to the family. This helps address emotional, financial, and practical needs during a challenging time. Option A is incorrect because the program does not directly reduce healthcare costs. Option B is incorrect as the focus is not solely on physical comfort but on comprehensive support. Option D is incorrect as the primary aim is not health promotion but rather addressing the family's immediate concerns and needs.
