Question

patients experiencing heatstroke would likely have which of the following signs and symptoms? select the six (6) that apply.

select all that apply:

• altered mental status.
• elevated blood pressure.
• heavy perspiration.
• hot skin.
• little to no perspiration.
• seizures.
• rapid pulse.
• weakness, dizziness.

Explanation:

Identify pathophysiology of heatstroke

Using the Classic Heat Stroke and Thermoregulation Pathophysiology knowledge points

• Heatstroke is a life-threatening emergency where the body's thermoregulatory mechanisms fail completely, leading to a core body temperature rising rapidly above \(104^\circ\text{F}\) (\(40^\circ\text{C}\)).
• Central nervous system dysfunction is a hallmark of heatstroke, manifesting as altered mental status, confusion, delirium, or seizures.

Evaluate clinical signs and symptoms

Using the Heat Stroke Assessment and Anhidrosis knowledge points

• Altered mental status: Present due to thermal injury to brain tissue.
• Elevated blood pressure: Absent; patients typically present with hypotension due to profound vasodilation and dehydration.
• Heavy perspiration: Absent; classic heatstroke is characterized by anhidrosis (dry skin), though exertional heatstroke may have some sweat, the general clinical sign is a lack of effective sweating.
• Hot skin: Present; core temperature is extremely high.
• Little to no perspiration: Present; anhidrosis is a key diagnostic sign.
• Seizures: Present; neurological irritability from extreme hyperthermia.
• Rapid pulse: Present; tachycardia occurs as a compensatory mechanism to increase cardiac output and dissipate heat.
• Weakness, dizziness: Present; early systemic signs of heat-related illness and cardiovascular strain.

Select the six correct options

• The six signs and symptoms that apply are:

1. Altered mental status.
2. Hot skin.
3. Little to no perspiration.
4. Seizures.
5. Rapid pulse.
6. Weakness, dizziness.
