A decrease in pulse strength during inhalation. Which means the pressure in the chest due to inhalation is stopping the ventricles in the heart to fill.

What is polypharmacy?
When a patient takes multiple medications at home.
In what kind of patients is it difficult to tell what normal breathing sounds like?
Small-volume nebulizer (SVN)
A device that uses compressed air or oxygen to nebulize a liquid medication into a mist that a patient can inhale.
A chamber that is connected to an MDI (metered dose inhaler) to collect the medication unit it is inhaled.
What should you do before removing the cap of a meterd-dose inhaler?
Shake it well for 30 seconds.
When the patient inhales the medication from the MDI canister what should you tell him to do?
Coach the patient to hold his breath.
What are side effects from taking a MDI?
Heart rate, tremors and nervousness.
What are the five rights of medication administration?
1) Right medication of drug 2) Right dose 3) Right route 4) Right time 5) Medication has not expired
What is the LPM for a nebulizer.
How many viles of albuterol go into a nebulizer.
A spacer is benefical because it helps the medicine to get into the patient's system faster? T or F
System composed of the heart and blood vessels which bring oxygen and nutrients to and take waste away from body cells. Also called cardiovascular system.
Cardiac conduction system
The specialized contractile and conductive tissues of the heart that generate electrical impulses that cause the heart to beat. Also called Coronary conduction system.
The ability of cells within the cardiac conduction system to generate a cardiac impulse on their own.
Blood vessels that carry blood away from the heart.
Veins that carry deoxygenated blood from the lungs to the left atrium of the heart.
Tiny blood vessels that connects an arteriole to a venule
The smallest branch of an artery which at its distal end leads into a capillary.
The smallest branch of a vein.
What are the two upper chambers of the heart
The left and right atria.
What are the two lower chambers of the heart?
The left and right ventricle.
The pace maker of the heart is called "____"
The sinoatrial node.
Their is three exceptions to the rule that states "arteries carry oxygenated blood" what are they?
The pulmonary artery and the pulmonary vein and the umbilical cord.
What does the pulmonary valve do?
The pulmonary artery carries deoxygenated blood from the right ventricle into the lungs
What does the pulmonary vein do?
It carries oxygenated blood from the lungs into the left atrium.
Why is the umbilical cord an exception to the artery rule?
The umbilical cord has two veins one artery and the veins carry oxygenated blood while the artery carries deoxygenated blood.
What are the four components of blood?
Red blood cells, white blood cells, Plasma, Platelets
What do red blood cells, (erythocrytes) do?
They give the blood it's color, carries oxygen to body cells, and carries carbon dioxide away from body cells.
What do white blood cells, (leukocytes) do?
Part of the blood that helps the body's immune system to defend against infection
what is plasma?
The liquid part of the blood
What are Platelets?
Blood components that are essential to the formation of blood cells.
What does the Sinoatrial (SA) node do?
It sets the heart to beat between 60-100 beats per minute.
What does the atrioventricular node do?
If the SA node fails the AV node takes over and sets the rate of the heart to beat 40-60 times per minute.
What does the Purkinje fibers do?
Once the Av node fails the Purkinje fibers will be the pacemaker for 20-40 beats per minute.
Where do electrical impulses start in the heart?
They start in the atrium go to the ventricle in a Superior to inferior fashion.
what does an electrocardiogram do?
A (ECG or EKG) is a graphic respresentation of the electrical activity within the heart.
What are Dysrhythmias?
Dysrythmias can decrease the amount of blood that is pumped into the heart.
If the heart doesn't get enough oxygen a heart attack may result.
What does Fibrinolytic therapy do?
Fibrinolytic therapy helps to dissolve clots by blocking the coronary artery. You must get a past pertinent medical history because this could cause life threatening hemorrhage if they had a recent stroke or major trauma.
What is different about diabetic cardiac patients?
They may not display common symptoms such as chest paint, SOB Etc... You always want ALS quicker for a diabetic cardiac event.
