## Question

A client collapses during outdoor work and is confused with hot skin and a core temperature of 40.3°C. Which action should the nurse take first while emergency help is activated?

## Option

1. Give oral electrolyte solution and allow the client to rest in a warm room
2. Remove excess clothing and begin rapid cooling now with cold water or ice **✔ Correct answer**
3. Administer acetaminophen and reassess the temperature after it takes effect
4. Cover the client with dry blankets to reduce heat loss during transport

**Correct answer: 2**

## Explanation

Confusion with marked hyperthermia after heat exposure indicates heat stroke, a medical emergency. Begin active rapid cooling immediately while emergency transport is activated; do not delay for oral fluids or antipyretic medication.

## In-depth explanation

Quick answer
Begin rapid active cooling while emergency help is activated. Altered mental status and marked hyperthermia distinguish heat stroke from uncomplicated heat exhaustion.

Why this is correct
Heat stroke means thermoregulation has failed and rising core temperature can rapidly injure the brain, liver, kidneys, and coagulation system. Removing excess clothing and using cold-water or ice-based cooling transfers heat away while definitive emergency care is arranged.

Easy analogy or mental picture
A dangerously overheating engine must be cooled while help is on the way, not left running until a test or medication works. The image explains urgency but does not replace airway support, monitoring, or safe clinical cooling procedures.

Memory hook
Heat exposure plus confusion means heat stroke: call for help and cool immediately.

NCLEX decision rule
When heat illness includes altered mental status or severe hyperthermia, treat it as heat stroke and start rapid cooling during emergency activation. Oral fluids are reserved for alert clients who can swallow safely, and antipyretics do not correct environmental hyperthermia.

Why the other choices are wrong
A confused client may aspirate oral fluids, and a warm room worsens heat retention. Acetaminophen does not reverse failed heat dissipation, while blankets interfere with the urgent need to remove heat.References
