The practical nurse (PN) is performing a focused assessment for a client with schizophrenia who is admitted to an acute care inpatient facility. Which behavior should the PN document as a symptom of schizophrenia?

A. Auscultate all lung fields: In left-sided heart failure, fluid backs up into the lungs, leading to pulmonary congestion and crackles. Assessing all lung fields allows the PN to detect early signs of worsening HF, such as pulmonary edema, which can rapidly become life-threatening.

B. Measure urinary output: Monitoring urine output is important for assessing kidney perfusion and fluid balance, but pulmonary congestion poses a more immediate risk in left-sided HF than changes in urine output.

C. Inspect for sacral edema: Sacral edema is more commonly associated with right-sided heart failure. While peripheral edema should be monitored, it is less critical than evaluating for pulmonary complications in left-sided HF.

D. Check mental acuity: Altered mental status can occur if hypoxia develops from severe pulmonary congestion, but initial assessment focuses on lung function to prevent acute respiratory compromise.

A. Oxygen saturation: Assessing oxygen saturation provides information about respiratory and circulatory efficiency, but dizziness upon standing is more often linked to hemodynamic changes rather than oxygenation issues.

B. Standing blood pressure: Measuring standing blood pressure is most important to assess for orthostatic hypotension, a common cause of dizziness in older adults. A significant drop in blood pressure upon standing indicates impaired vascular response, which increases the risk of falls and injury.

C. Pulse deficit: Evaluating for a pulse deficit helps detect cardiac arrhythmias, but it is not the most relevant initial assessment for postural dizziness. Orthostatic blood pressure changes should be ruled out before exploring other cardiovascular causes.

D. Apical heart rate: While assessing the apical rate can detect irregularities in rhythm, it does not explain dizziness triggered by position changes. Postural blood pressure measurement provides more specific information about the cause of dizziness in this scenario.
