A nurse is caring for a client who has lung cancer and has a sealed radiation implant. Which of the following actions should the nurse take? (Select all that apply)

Choice A reason: High-osmolarity formulas may cause diarrhea but are not directly linked to aspiration risk. Aspiration results from improper positioning or reflux, not formula osmolarity, so this factor is less relevant, making it incorrect for identifying aspiration risk in enteral feedings.
Choice B reason: Sitting in high-Fowler’s position (60-90 degrees) reduces aspiration risk by promoting gastric emptying and preventing reflux during enteral feedings. This is a protective measure, not a risk factor, making it incorrect for this scenario.
Choice C reason: A residual of 65 mL 1 hour postprandial is within acceptable limits (<100-200 mL, per facility protocol) and does not indicate high aspiration risk. Elevated residuals may suggest delayed emptying, but this value is normal, making it incorrect.
Choice D reason: A history of gastroesophageal reflux disease increases aspiration risk, as reflux can allow gastric contents to enter the airway during enteral feedings. This condition compromises esophageal sphincter function, making it a significant risk factor and the correct choice.

Choice A reason: Cardiogenic shock involves reduced cardiac output, typically with low PAWP due to decreased preload from poor heart function. Elevated PAWP reflects left atrial pressure buildup, not characteristic of cardiogenic shock alone, which is distinct from heart failure, requiring specific hemodynamic management.
Choice B reason: Elevated PAWP indicates left ventricular failure, where the heart cannot pump blood effectively, causing pulmonary congestion. This increases left atrial pressure, leading to pulmonary edema, a hallmark of heart failure. Diuretics and inotropes are needed to reduce fluid overload and improve cardiac function.
Choice C reason: Hypotension is a symptom, not a direct complication of elevated PAWP. It may occur in heart failure due to reduced cardiac output, but elevated PAWP specifically signals left heart dysfunction, not hypotension itself, which is a systemic response rather than a primary cardiac issue.
Choice D reason: Hypovolemia reduces blood volume, lowering PAWP due to decreased preload. Elevated PAWP suggests fluid overload or left ventricular dysfunction, not hypovolemia, which presents with low central venous pressure and dehydration signs, requiring fluid resuscitation rather than management of heart failure.
