Answer:
Cholinergic systems which are an organisation of nerve cells that uses acetylcholine in communicating nerve impulses are found everywhere in the human central nervous system.
It is speculated that they are crucial to learning, attention, memory, speaking and carrying out purposive movements. This is because of their high density in the thalamus, striatum, limbic system, and neocortex.
Cholinergic agents are biochemical compounds which produce the same effects as acetylcholine and/or butyrylcholine.
Studies show that the parasympathetic nervous system (which comprise of the rest and digest system and conserves energy decelerating the heart rate, accelerating intestinal and gland activity etc) uses acetylcholine to a great extent to communicate its messages and is said to be mostly cholinergic.

Placing of the hand above the chest is the first step while administering CPR after ensuring that the environment is safe.
When the heart stops beating, CPR, or cardiopulmonary resuscitation, is a life-saving emergency operation. After cardiac arrest, immediate CPR can increase survival rates by a factor of two to three.
A person's heartbeat will cease if they are not breathing. To aid with circulation and to assist the body to receive oxygen, use CPR (chest compressions and rescue breaths). Following are the steps of CPR:
- Placing of the hand above the chest.
- Interlocking of fingers.
- Giving chest compressions.
- Opening of the airway.
- Delivering rescue breathes.
- Watching the patient's chest fall.
- Repeat steps 3 and 4.

A patient has been diagnosed with angina. As he talks with the nurse, he asks several good questions about angina and seems able to concentrate on the explanations. He seems eager to learn how to manage his condition. What assessment can be made by the nurse <u>Hardiness</u>
<h3>What is
angina?</h3>
Chest pain or pressure, often known as angina or angina pectoris, is a sign of coronary heart disease and is typically brought on by insufficient blood flow to the heart muscle (myocardium).
A blockage or spasm of the arteries that feed blood to the heart muscle is typically the cause of angina. Anemia, abnormal cardiac rhythms, and heart failure are among additional factors. Atherosclerosis, a component of coronary artery disease, is the primary mechanism of coronary artery occlusion. The phrase means "a strangling feeling in the chest" and is derived from the Latin words angere ("to strangle") and pectus ("chest").
The degree of oxygen deprivation in the heart muscle and pain intensity are only weakly correlated.
