A nurse is preparing to perform a dressing change on a preschooler. Which of the following actions should the nurse take to prepare the child for the procedure?

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: Increased energy and motivation signal improvement in major depressive disorder, countering fatigue and anhedonia. Serotonin and norepinephrine rebalance, often from treatment, restores drive and engagement, reflecting neurochemical stabilization in the brain’s limbic system, critical for mood regulation and recovery.
Choice B reason: Self-doubt in decision-making reflects persistent depressive symptoms, like low self-esteem and cognitive impairment. Negative thought patterns, driven by altered prefrontal cortex activity, indicate ongoing depression, not improvement, requiring adjusted interventions to address these neurocognitive deficits in major depressive disorder.
Choice C reason: Sleeping 12 hours daily indicates hypersomnia, a depressive symptom, suggesting no improvement. Disrupted circadian rhythms and serotonin dysregulation cause excessive sleep, contrasting with recovery signs like normalized sleep patterns. This reflects persistent neurochemical imbalances hindering mood stabilization in depression.
Choice D reason: Social isolation is a core depressive symptom, driven by anhedonia and low mood, indicating no improvement. Withdrawal reflects ongoing dopamine and serotonin imbalances, preventing social engagement. Recovery involves increased interaction, making isolation a sign of persistent major depressive disorder.
