A nurse assesses a patient whose arterial blood pressure is 86/54 mmHg. Which finding requires the most immediate follow-up?
Correct answer: B. Urine output of 15 mL in one hour
- A. Warm skin and a regular pulse
- B. Urine output of 15 mL in one hour
- C. Mild thirst after a meal
- D. Capillary refill of two seconds
Explanation
Urine output of 15 mL in one hour suggests reduced renal perfusion and possible inadequate circulating volume. This is a circulation concern and should be followed promptly, while the other findings are less suggestive of poor perfusion.

About Cardiovascular System
The cardiovascular system covers the chambers, valves and major vessels of the heart, the cardiac cycle, conduction pathway, blood pressure and the circulation through pulmonary and systemic circuits. It also explains artery, vein and capillary structure, exchange at capillary beds, and how the cardiac cycle differs from general blood flow.
