Paresthesia is an early sign of which condition?

• A. Cardiac ischemia
• B. Respiratory failure
• C. Neurovascular impairment
• D. Hypoglycemia

Answer: (C)

Paresthesia signals disturbance of nerve function due to compromised neurovascular supply. When nerves aren’t getting adequate blood flow or are irritated, sensory fibers send abnormal signals, producing tingling, numbness, or burning sensations—an early cue that neurovascular tissue is being affected. Other options don’t fit this early sensory sign as well: cardiac ischemia usually presents with chest discomfort or referred pain; respiratory failure shows breathing difficulty and hypoxemia; hypoglycemia presents with autonomic symptoms like sweating or tremor and sometimes confusion.
