Question

A man was brought to the emergency after suddenly becoming unconscious while working inthe field. On examination, his temperature was 105 degrees Fahrenheit, and his skin turgorwas decreased. Which of the following would not be seen in the patient?

• A. Tachypnea
• B. Hypotension
• C. Sweating
• D. Red hot skin

Answer 1

The Correct Option is C

To determine which symptom would not be observed in the patient described, we must consider the physiological response to the scenario presented.

The patient is experiencing heatstroke, characterized by:

• High body temperature (≥104°F)
• Central nervous system dysfunction (e.g., unconsciousness)
• Reduced skin turgor indicating dehydration

During heatstroke, the body's ability to regulate temperature is overwhelmed, often leading to an absence of sweating, contrary to the body's usual cooling mechanism through perspiration. The symptoms typically observed include:

• Tachypnea: Increased breathing rate to compensate for possible hypoxia or metabolic acidosis.
• Hypotension: Low blood pressure due to dehydration and vasodilation.
• Red hot skin: The skin appears flushed and hot due to increased blood flow and lack of sweating.

Therefore, sweating would not be seen in this patient, as heatstroke impairs the body's ability to sweat.
