For a patient with congestive heart failure, what is the priority assessment that guides therapy?

• A. Check blood sugar daily
• B. Monitor respiratory rate constantly
• C. Weigh daily
• D. Assess bowel sounds

Answer: (C)

In congestive heart failure, fluid status directly drives symptoms and therapy decisions, so the most useful, actionable assessment is daily weight. A small, rapid increase in weight signals fluid retention and potential decompensation, often before visible edema or shortness of breath worsen, prompting timely adjustments to diuretic therapy to prevent hospital admission. To make this information reliable, weigh the patient at the same time each day using the same scale, after voiding, and report the trend over several days rather than a single value.

Monitoring respiratory rate can help detect pulmonary congestion, but it doesn’t guide therapy changes as consistently as a measurable weight trend. Checking blood sugar daily and assessing bowel sounds don’t directly steer heart failure management, making them less relevant as the primary guiding assessment.
