Correct Answers
Heat cramps ✅muscle spasms that result from a loss of large amounts of salt and
water through perspiration
Heat Cramps Symptoms ✅Nausea, tachycardia, pallor, weakness, and profuse
diaphoresis are often present..
Heat Cramps Treatment ✅-Rest
-water and fluids
-remove from hot environment
Heat exhaustion ✅condition resulting from exposure to heat and excessive loss of fluid
through sweating; Temperature 99.6° to 105.8°F
Clinical syndrome characterized by fatigue, nausea, vomiting, extreme thirst, and
feelings of anxiety (altered mental status).
Hypotension, tachycardia, elevated body temperature, dilated pupils, mild confusion,
ashen color, and profuse diaphoresis are present.
Heat Exhaustion Treatment ✅Always correlate fluid replacement to clinical and
laboratory findings. Place a moist sheet over the patient to decrease core temperature
through evaporative heat loss.
Consider hospital admission for older adults, the chronically ill, or those who do not
improve within 3 to 4 hours.
Risk factors for heat related emergencies ✅Alcohol
Age
• Infants
• Older adults
Heat stroke ✅is the most serious form of heat stress and is a medical emergency.
Results from failure of the hypothalamic thermoregulatory processes. Temperature
>105.8°F
Increased sweating, vasodilation, and increased respiratory rate deplete fluids and
electrolytes, specifically sodium. Sweat glands stop functioning. Core temperature
increases rapidly, within 10 to 15 minutes
Altered mental status (ranging from confusion to coma)
• Hot, dry skin
• Hypotension
• Tachycardia
• Tachypnea
Weakness
Heat stroke can lead to ✅cerebral edema= brain death
Heat Stroke Treatment ✅-stabilizing the patient's abcs
- rapidly reducing the core temperature, and monitoring for dysrhythmias.
-Give 100% O2 to compensate for the patient's hypermetabolic state. Ventilation with a
BVM or intubation and mechanical ventilation may be needed. --Place the patient on
continuous ECG monitoring and pulse oximetry. Monitor laboratory findings.
-Correcting electrolyte imbalances and coagulation abnormalities is critical.
-Place the patient in a cool environment. Promote evaporative cooling by removing
clothing and spraying the patient with lukewarm water in front of a large fan.
