Station I
Blood pressure (12 points) and pulses (5)

Scoring—give 1 point each.

1. Demonstrate on a teammate how blood pressure is taken.

____Correctly places cuff and stethoscope

____pumps up cuff

____listens as cuffs deflates

2. Explain the procedure.

____The bell of the stethoscope is placed over the brachial artery

____The artery is squeezed until the blood flow stops when the cuff is inflated

____As the cuff deflates, the pressure is measured when the Korotkoff sound is first heard and when it is last heard

3. Name the instruments and the units of measurement of blood pressure.

____stethoscope

____sphygmomanometer

____mm Hg (millimeters of mercury)

4. Name the top and bottom number and the blood pressure for an average adult.

____systolic

____diastolic

____120 over 70

5. Demonstrate taking these pulses:

____Posterior tibialis

____Popliteal

____Carotid

____Radial

____Dorsalis pedis

Station II
Cardiovascular System

1. Point with a pencil to the following:

Right main bronchus
Oropharynx
An alveolus
A pulmonary vein
Larynx
A coronary artery
A coronary vein
Trachea
Diaphragm

2. Identify the structure with these numbers on the model.

50 (inferior vena cava)
45 (superior vena cava)
64 (aortic valve)
63 (aorta)
51 (tricuspid valve)
61 (mitral valve)
65 (pulmonary valve)
61 (left atrium)
51 (right atrium)
69 (left ventricle)
55 (pulmonary artery)
59 and 60 (pulmonary veins)

3. Describe the location of the heart in the body and approximate size and shape.

4. Describe the major vessels or other chambers that carry blood to or away from each of these four chambers.

Chambers Carries blood to it Carries blood away from it
Left atrium    
Right ventricle    
Right atrium    
Left ventricle

4. What is the pericardium and what does it do?

5. Match the phases of the heart on the left with the descriptions on the right by drawing a line to the correct phrase. Only one match per phase please.

Phase 1 Ventricles contract and force blood into the main arteries
Phase 2 Atria relax and blood flows in from the main veins
Phase 3 Atria empty blood into the ventricles
Phase 4 Systole

6. Match the structures on the left with their descriptions on the right by drawing a line to the correct answer.

Pulmonary vein Closes during diastole
Pulmonary arteries Carries low-oxygenated blood
Aortic valve Carries blood to the heart
Tricuspid valve Opens during diastole

7. Match the stage of the EKG with its description on the right (draw a line to the correct answer.)

p wave Ventricular contraction
T wave Electrical system recovery
QRS wave Atria contract
PR segment AV node

8. Draw and label a typical EKG tracing corresponding to one heart beat.

9. Match the cardiac term on the left with its closest description on the right.

cardiac output The proportion of blood squeezed out of the ventricle in systole
mean arterial pressure Volume of blood squeezed out of the ventricle in systole
ejection fraction  Systolic blood pressure plus diastolic blood pressure divided by two
stroke volume  Increased as much as four times during exercise

10. The cardiac output is 20 L per minute. The ventricle contains 300 mls of blood. Its ejection fraction is 55%.

Is this person at rest or exercising?

What is the pulse rate?

Station III
Respiratory System

1. Match the proportions of these gases in the air:

 
Nitrogen 0.33%
Oxygen 78%
Carbon dioxide  1%
Inert gases  21%

2. Match the phases of ventilation with the descriptions on the right by drawing a line.

INSPIRATION Passive process
  Negative pressure in the lungs
EXPIRATION Diaphragm relaxes

3. The right lung has _____ number of lobes.



4. Define:

Anatomically dead space

Residual volume

Tidal Volume

5. What keeps the trachea open during breathing?

Station IV
Nutrition

1. Draw the food guide pyramid, label each section with its major food groups and recommended servings.

2. Calculate the total calories in one serving of graham crackers (8 crackers.)

The label indicates that the amount per serving is as follows

Total fat—.5 g

Total carbohydrate—23 g

Protein—2 g

3. Name a mineral important for the following

strong bones and teeth 
blood with adequate hemoglobin 
proper taste and hearing 
proper fluid balance 

4. Match these vitamins with their function and a food source.

Vitamin B-12  Maintains healthy skin, eyes, bones, teeth
Vitamin D Antioxidant
Vitamin C  Fat soluble
Vitamin A  Prevents anemia

5. What are the basic building blocks of protein?

How many are there?
