The practical nurse (PN) is assessing an older client with left-sided heart failure (HF). What intervention is most important for the PN to implement?

Choice A rationale: While measuring urinary output is an important nursing intervention, it may not be the most critical action for a client with left-sided heart failure. Left-sided heart failure primarily affects pulmonary circulation, and assessing lung sounds is a priority in this situation. Choice C rationale: Checking mental acuity is a valid nursing intervention, but it may not be the most crucial action for a client with left-sided heart failure. The priority in this case is to monitor respiratory status and identify any signs of respiratory distress. Choice D rationale: Inspecting for sacral edema is also a relevant nursing intervention, as it can indicate fluid retention in heart failure patients. However, auscultating the lung fields takes precedence in this scenario to assess for signs of pulmonary congestion, which is a common complication of left-sided heart failure.
