Which indicators should prompt immediate LVAD assessment?

• A. Urine output
• B. Cholesterol levels
• C. Device alarms, battery status, audible pump sounds, and overall device function
• D. Only blood pressure readings

Answer: (C)

In LVAD care, the most immediate concerns are the device’s operational cues—power, alarms, and pump performance. These indicators directly show whether the device is delivering support as intended. Alarms point to faults or issues needing urgent attention; battery status reveals if there’s stable power available to keep the device running; audible pump sounds provide real-time clues about flow or mechanical problems; and the overall device function combines these signals to gauge the LVAD’s reliability at that moment.

Urine output reflects perfusion but doesn’t diagnose device function itself and can lag behind; cholesterol levels are long-term risk markers rather than acute indicators; blood pressure readings can be unreliable with continuous-flow LVADs, making them less informative for immediate device assessment. Focusing on device alarms, battery status, audible pump sounds, and overall device function gives the most direct, actionable picture for prompt LVAD assessment.
