Question 1

What is the antidote for opioid overdose?

Accepted Answer

Naloxone

Answer

Naloxone is a specific opioid antagonist that rapidly reverses the effects of opioid overdose. It works by binding to opioid receptors in the brain, displacing opioids and blocking their effects, particularly respiratory depression. This can quickly restore normal breathing and consciousness in someone experiencing an opioid overdose.

Question 2

What is a symptom of carbon monoxide poisoning?

Accepted Answer

Headache and confusion

Answer

Carbon monoxide (CO) is a colorless, odorless gas that binds to hemoglobin more readily than oxygen, leading to cellular hypoxia. Common symptoms of CO poisoning, often mistaken for flu, include headache, dizziness, nausea, and confusion. Severe poisoning can lead to loss of consciousness, seizures, and death due to oxygen deprivation to vital organs.

Question 3

How is heat stroke treated?

Accepted Answer

Cool and hydrate

Answer

Heat stroke is a severe, life-threatening condition caused by the body overheating, often due to prolonged exposure to high temperatures or physical exertion in the heat. The primary treatment involves rapid cooling of the body, such as with ice packs or cool water immersion, and rehydration to lower core body temperature and restore fluid balance.

Question 4

What is the first action in suspected sepsis?

Accepted Answer

Antibiotics

Answer

Sepsis is a life-threatening condition caused by the body's overwhelming response to an infection, leading to organ dysfunction. Administering broad-spectrum antibiotics as quickly as possible is critical in suspected sepsis to target the underlying infection and prevent its progression. Early antibiotic therapy significantly improves patient outcomes and survival rates.

Question 5

Which lab helps confirm infection?

Accepted Answer

WBC count

Answer

A White Blood Cell (WBC) count, also known as a leukocyte count, is a common laboratory test used to help identify and monitor infections. An elevated WBC count (leukocytosis) often indicates that the body's immune system is actively fighting an infection, as it produces more white blood cells to combat pathogens.
