Question 1

Bleeding from a neck wound presents a unique danger because it can:

Accepted Answer

Result in air embolism if a vein is punctured

Answer

Neck veins can draw air into the circulatory system, causing a potentially fatal air embolism; wounds should be covered with an occlusive dressing.

Question 2

When treating a subject with a suspected open chest wound (sucking chest wound), the officer should:

Accepted Answer

Apply a vented chest seal or occlusive dressing taped on three sides

Answer

A vented chest seal or three-sided occlusive dressing allows air to escape during exhalation but prevents air from entering during inhalation, stabilizing the chest.

Question 3

A patient presents with cool, clammy skin, rapid weak pulse, rapid shallow breathing, and altered consciousness after a motor vehicle collision. These are classic signs of:

Accepted Answer

Hemorrhagic shock

Answer

Cool clammy skin, tachycardia, tachypnea, and altered mental status together indicate the body's compensatory response to significant blood or fluid loss — hemorrhagic shock.

Question 4

Which of the following best describes the proper rate of chest compressions during adult CPR?

Accepted Answer

100-120 compressions per minute

Answer

Current AHA guidelines recommend a compression rate of 100-120 per minute to generate adequate cardiac output during CPR.

Question 5
