Explanation

The hinge joints allow movement in one plane only,

That is up and down or backward and forward.

The fingers, toes, elbows, knees, and ankles contain hinge joints.

Explanation

Adrenaline (also known as epinephrine) increases the following effects on the heart:

Heart Rate:

Adrenaline increases the heart rate (positive chronotropic effect).

Contractility:

It increases the force of heart muscle contractions (positive inotropic effect).

Conduction Velocity:

It enhances the speed of electrical conduction through the heart (positive dromotropic effect).

Cardiac Output: 

Due to the increased heart rate and contractility, adrenaline boosts the overall cardiac output.

Explanation

Chemical substances used on living tissues to inhibit the growth of microorganisms are called antiseptics.

Explanation

Acute Carbon Monoxide Poisoning is marked by Brain Edema.

Severe carbon monoxide poisoning can cause the skin to turn a cherry-red color.

Brain edema (swelling of the brain) is a serious consequence of severe carbon monoxide poisoning due to hypoxia (lack of oxygen) in brain tissues.

Symptoms of acute carbon monoxide poisoning can also include :

• headache
• dizziness
• weakness

Explanation

The muscles that never fatigue are the heart muscle (cardiac muscle)

Cardiac muscle has more mitochondria than skeletal muscle (up to 35% compared to 1-2%), Which makes it resistant to fatigue.

Mitochondria are essential for generating ATP, the cell's energy source.

Other muscles, such as skeletal muscles, can experience fatigue and failure under strenuous conditions.

Explanation

A person who helps a patient/victim regain his/her consciousness/strength is called a Rescuer or First responder

Explanation

The information gathered during assessment and providing first aid is collectively called a Clinical Assessment.

Because this term encompasses the process of collecting and analyzing relevant information about a patient's condition.

It involves evaluating symptoms, vital signs, and other pertinent data to form an understanding of the patient's immediate health status.

Explanation

A wound should be covered with a roller bandage to prevent infection and dirt from getting inside.

Explanation

A place that does not have safe oxygen levels is typically referred to as a "Confined Space."

Where serious injury can occur from hazardous substances or conditions within the space or nearby (e.g. lack of oxygen)

There are two types of confined spaces

• Permit
• Not-Permit

Explanation

Therapeutic and Medical communication process in which the healthcare professional consciously uses specific techniques

To help patients better understand their condition or situation
