A charge nurse is supervising a newly hired nurse who is instructing a client about how to use a walker. For which of the following actions should the charge nurse intervene?

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: Amniocentesis involves needle insertion through the uterine wall, which can irritate the uterus and trigger contractions, risking preterm labor at 33 weeks. Monitoring contractions is vital to detect early labor signs, enabling interventions like tocolytics to delay delivery. This protects the premature fetus, ensuring better outcomes by maintaining pregnancy until closer to term.
Choice B reason: Vomiting is not a typical amniocentesis complication. The procedure is localized to the uterus, with minimal systemic effects. Nausea may occur from anxiety, but vomiting is rare and not a priority for monitoring. Focus remains on uterine and fetal complications, like contractions or fluid leakage, which directly impact pregnancy safety and outcomes.
Choice C reason: Hypertension is not directly linked to amniocentesis. The procedure does not typically affect maternal cardiovascular function, as it’s a localized intervention. Monitoring for hypertension is more relevant for conditions like preeclampsia. Post-amniocentesis, the priority is uterine activity and fetal distress, not blood pressure, making this an irrelevant complication to monitor.
Choice D reason: Polyuria is not associated with amniocentesis, as the procedure does not impact renal function or fluid balance. The focus is on complications like contractions, bleeding, or amniotic fluid leakage, which pose direct risks to the pregnancy. Monitoring polyuria is unnecessary, as it does not reflect the procedure’s physiological effects or risks.
