A blood pressure monitoring machine is giving erratic/fluctuating readings. What should be done FIRST?

Correct answer: B. Check the blood pressure cuff and tubing for proper placement or leaks

• A. Physician referral may be needed if true hypertension is confirmed, but equipment troubleshooting comes first.
• B. Correct. When a blood pressure machine gives erratic readings, the first step is to check the equipment — ensure the cuff is properly positioned, the tubing is intact (no kinks or leaks), and the device is functioning correctly. Recheck with a manual sphygmomanometer if needed.
• C. Erratic machine readings do not constitute an immediate emergency — equipment check is the first step.
• D. Recording erratic readings without investigating equipment malfunction is inappropriate.
