Question 1

Name the 5 phases of coagulation

Answer 1

1. vascular phase (vessel constricts)
2. Platelet phase (Cells clump to plug leak)
3. Coagulation Phase (blood clot forms)
4. Clot Retraction (Clot shrinks as tear heals)
5. Fibrinolysis(Clot Dissolves)

Name the 6 links in the chain of infection

Answer 2

1. Infectious agent
2. Reservoir
3. Portal of exit
4. Mode of transmission
5. Portal of entry
6. Susceptible Host

Question 3

Standard Precautions

Answer 3

for all pt: Use PPE when handling bodily fluids, non intact skin, or mucous membrane perform hand hygiene before and after contact with a Pt. and safely dispose of used equipment

Question 4

Airborne Precautions

Answer 4

for infections spread via droplets smaller than 5 microns; wear respiratory protection

Question 5

Droplet Precautions

Answer 5

for infections spread via droplets larger than 5 microns: wear a mask

Question 6

Contact precautions

Answer 6

for infections spread through contact: wear gloves and gowns

Question 7

Analytical Communicators

Answer 7

prefer to work with real numbers, facts and data. they place very little emphasis on feelings or emotions

Question 8

Intuitive Communicators

Answer 8

prefer to look at the big picture. While this can be an efficient style, it can result in more questions than answers when using too broad an approach.

Question 9

Functional Communicators

Answer 9

Prefer an organized approach with timelines and detailed plans, using a step-by-step method to solve problems and communicate information. this can be an effective style of communication as long as the patient doesn’t become overwhelmed with details.

Question 10

Answer 11

1. Sender develops the message
2. Sender encodes message into transmittable format
3. sender transmits message
4. receiver decodes the message
5. receivers interprets the message
6. reciever provides feedback

Question 12

4 Chambers of the Heart

Answer 12

1. Right Atrium
2. Left Atrium
3. Right Ventricle
4. Left Ventricle

Question 13

How Blood travels through the heart

Answer 13

Both atria begin relaxed. blood flows from the superior and inferior venae cavae into the right atrium and from the pulmonary veins into the left atrium. Atrial contraction occurs simultaneously, forcing blood into both ventricles. as the atria relax, both ventricle contract and force blood out of the heart. the right ventricle forces deoxygenated blood to the lungs via the pulmonary arteries, and the left ventricle forces oxygenated blood to the body.

Question 14

How the heart’s conduction system works

Answer 14

conduction system consists of 2 nodes:
the SA node and the atrioventricular (AV) node, which transmits the signal to the bundle of His following atrial contraction. this collection of nerves located between the Atria and Ventricles then transmits the signal to the finger- like projections located throughout the ventricular muscle - called Purkinje fibers – to trigger ventriclar contraction.
