A nurse is caring for a client who has heart failure. After reviewing the findings, which of the following actions should the nurse take? For each potential provider's prescription, click to specify if the prescription is anticipated, nonessential, or contraindicated for the client.

Decrease the client's oxygen to 1 L/min via nasal cannula: The client’s oxygen saturation dropped to 90% on 2 L/min, so decreasing oxygen could worsen hypoxia. This prescription is nonessential/unsafe. Begin a 24-hr urine collection for the client: Routine 24-hour urine collection is not required for heart failure management unless assessing renal function for a specific indication; therefore, nonessential. Restrict the client's fluid intake to 2 L per day: Fluid restriction is anticipated in clients with heart failure to help manage fluid overload, especially given the 1.8 kg (4 lb) weight gain in 24 hours. Hold the client's metoprolol: The client has atrial fibrillation and hypertension, and beta-blockers are essential for rate control and reducing cardiac workload; holding the medication is contraindicated unless specifically ordered for a critical adverse event. Increase the dosage of furosemide: The client shows signs of fluid overload (weight gain, decreased oxygen saturation, elevated BNP). Increasing the diuretic dose is anticipated to manage fluid retention. Weigh the client daily: Daily weights are anticipated in heart failure management to monitor fluid status and guide therapy.
