Answer 2

LEFT 5th or 6th intercostal space — midclavicualr line

Question 3

HEART RATE: With the subject’s hand (1), compress the (2) at the (3) portion of the distal end of the forearm with the pads of your index and the middle finger until (4) is detected.

Do the same thind to the opposite forearm. Then for a minute, count the number of (5) felt on the radial pulse

Answer 3

1. pronated
2. radial artery
3. antero-lateral
4. maximal pulsation
5. aretrial pulsations

Question 4

3. Muscle Exercise and Gravity

Not done:
4. Blood Pressure
5. Valves and Blood Flow Direction

Question 7

BLOOD PRESSURE

1. Let the subject seat comfortable on a chair with his/ her forearms (1) and suupported to place the (2) at the level of the (3)

Answer 7

1. supinated
2. antecubital crease
3. heart

Question 8

BLOOD PRESSURE

2. Free the selected arm from any (1)
3. Palpate the (2) to confirm viable pulse

Answer 8

1. clothing
2. brachial artery

Question 9

BLOOD PRESSURE

4. Snugly fit [(1) fingers could be inserted] the arm cuff with the lower end about (2) above the crease

Answer 9

1. 2-3
2. an inch

Question 10

BLOOD PRESSURE

5. Palpate the (1) in the arm then inflate the arm cuff noting the level at which the (1) disappears, then open the (2) very fast to release the air in the cuff

Answer 10

1. radial pulse
2. air valve

Question 11

BLOOD PRESSURE

6. Let the subject ‘open & close’ his hands (1) times.
7. Position the ste’s diaphragm on the (2) then inflate once again the cuff to a level (3) above the level at which the radial pulse earlier disappeared.
8. Slowly release the air valve and look at the (4) to identify where the first—loudest sound and second— softest sound is heard. Once the last sound is heard, open the air valve totally.
9. Look at the result

Answer 11

1. 30
2. brachial artery
3. 30mmHg
4. gauge
