The process of heart contraction stimulates by the initiation of an electrical impulse. This electrical impulse starts in the SA node.
<h3>What is the Heart contraction?</h3>
Heart contraction may be defined as a type of physiological activity that stimulates electrical impulses which are initiated by the sinoatrial node. Systole is significantly the contraction phase of the cardiac cycle.
The SA node is a small bundle of specialized cells that is remarkably located in the right atrium. The electrical activity escalates through the walls of the atria and induces them to contract. This action finally forces blood into the ventricles.
Therefore, the SA node is responsible for the initiation of impulses that stimulates heart contraction.

Answer:
#1 It is important to ask the victim questions for many reasons. These reasons include:
- Keeping them awake and conscious. If they have a concussion, its important that they stay awake for better medical examination. (I speak from experience)
- Asking them questions and seeming interested in them helps them relax and makes them feel like they are in good hands.
- If someone caused their injuries, for example, attempt of murder, asking questions could give clues about the perpetrator.
- The EMT/DR/nurse could ask questions to find more important info about the victim. Example: Medical conditions, allergies, emergency contacts, age, name, past medical records, if they are pregnant or breastfeeding, ETC.
#2 All medications have some possible side affects. Some are mild, but others can result in a serious allergic reaction or even death.
For example, approximately 10% of the US population is allergic to Penicillin. The reaction varies from person to person.
It is important to know of any medical conditions because certain procedures or medications can cause those medical conditions to worsen. Then you have to do more work on the victim that really needed :/
#3 Main questions include:
- What caused your injuries?
- Do you smoke/chew tobacco/do drugs/drink alcohol? (If yes to any/all) When was the last time you did?
- (If female) Is there a possibility that you are pregnant, trying to get pregnant or breastfeeding?
- Is there someone you would like us to call?
There are several other questions that should be asked with each different situation. Always get as much information as you can so that you can help the patient as best as possible.
Tip: If victim is unconscious, look for any medical information in wallet, emergency medical information spot on phone, or even on a key chain. You could also call one of their emergency contacts for information.
#4 Maintain eye contact. Be kind, calm, and honest. Take good care of them. Its all in the job.
I am not a professional, but I have seen this done a time or two :) Hope this helps!!
When preparing food, it is especially important to keep the temperature out of the danger zone because bacteria can grow rapidly in this temperature range.
Bacteria grow at very high speeds in the range of the danger zone, which is the range of temperatures between 40° F and 140° F. Leaving food out at room temperature for a long time (more than 1-2 hours) can lead to some bacteria to grow to levels which are dangerous.
Hope this helps:)
