A nurse is preparing to insert a peripheral intravenous line on an infant. Which of the following actions should the nurse plan to take?

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.

Choice A reason: An HbA1c of 7.2% in type 1 diabetes indicates suboptimal control but is not an acute emergency. This client requires follow-up but is stable compared to life-threatening conditions, so they are not require immediate assessment, making this incorrect for prioritization.
Choice B reason: New-onset tachypnea in a hip fracture client suggests a life-threatening issue like pulmonary embolism, a common complication due to immobility. This requires immediate assessment to ensure airway and circulatory stability, aligning with ABC priorities, making it the correct first action for the nurse to take.
Choice C reason: Sinus arrhythmia is typically benign, especially with cardiac monitoring in place. It does not indicate an immediate threat compared to respiratory distress, so this client can be assessed later, making this incorrect for first priority assessment.
Choice D reason: Chest pain in a hypertensive client is concerning for cardiac issues, but tachypnea in a hip fracture suggests a more acute, potentially fatal condition like pulmonary embolism. Respiratory distress takes precedence, so this is incorrect for immediate assessment.
