What are the 5 circumference points? Ans✓✓✓-- Arm (midpoint between
acromian and olecranon)
- Waist (midpoint of iliac crest and ribs)
- Hip (furthest protrusion of glutes)
- Thigh (midpoint of inguinal crease and patella)
- Calf (furthest protrusion)
Describe the pros and cons of skinfold measurements Ans✓✓✓-Pros: accurate
for leaner subjects, multiple equations for different populations
Cons: high rate of user error, taking repeated measurements can increase error,
can be impacted by physical activity (level of water in muscles)/ environment
(cold/hot weather), shouldn't be used for obese clients
Describe skinfold protocol Ans✓✓✓-Explain the purpose of the test
Explain the test procedures
Measure skinfolds on right side of body at eye level
Lift fold 1 cm above desired site, place calipers directly over desired site
Position calipers perpendicular to site of measurement
Administer 2 trials within 1mm
Measure skinfolds in rotational order
DO NOT REMOVE FINGERS PINCHING WHILE MEASURING
,What are the 7 skinfold sites? Ans✓✓✓-- Tricep (midpoint of acromian and
olecranon)
- Bicep (belly of bicep)
- Scapula (3cm inferior)
- Waist (3cm superior of iliac crest)
- Stomach (3cm lateral and 1cm inferior of belly)
- Thigh (midpoint of inguinal crease and prox patella)
- Calf (widest medial point)
Describe the pros and cons of bioelectrical impedance Ans✓✓✓-Pros: easy to
use, fairly reliable, quick results
Cons: can be impacted by client age, water level, cannot be used with people with
pacemakers
Describe the pros and cons of DEXA Ans✓✓✓-Pros: very reliable, can highlight fat
distribution
Cons: movement may disrupt image, expensive, exposure to radiation
Describe the process of taking BP Ans✓✓✓-1. Locate and palpate radial pulse
2. Close valve and increase pressure to 70 mmHg
3. Slowly increase pressure further until pulse disappears
4. Position earpieces of stethoscope in line with auditory canals
5. Place diaphragm of stethoscope over brachial pulse
6. Close valve and increase pressure to 20-30 mmHg above systolic estimate
7. Release pressure slowly
8. Note pressure of first Korotkoff sound (systolic)
,9. Note measurement of Phase V diastolic pressure
10. Continue deflating cuff for at least 10 mmHg.
11. Continue listening for further sounds
12. Record Systolic and Diastolic values
13. Repeat and compare to 1st trial
14. Correctly classify resting blood pressure
What are the stages of BP? Ans✓✓✓-Normal - <120/<80
Prehypertension - 120-139/80-89
Stage 1- 140-159/90-99
Stage 2 - > 160/100
Hypertensive crisis >180/110
Describe the normal and abnormal HR response to exercise Ans✓✓✓-Normal:
increase in HR depending on what type of exercise
Abnormal: sudden increase in HR, increase in HR with no increase in CO
Describe the normal and abnormal BP response to exercise Ans✓✓✓-Normal:
increase in systolic BP and a slight increase in diastolic BP
Abnormal: no increase in BP, severe hypotension post exercise, large increase in
DBP
What is mean arterial pressure? Ans✓✓✓-Average pressure in arteries during
one cardiac cycle (65-110)
5 lead EKG Ans✓✓✓-Green - right lower ribs
, White - right inferior to clavicle
Black - left inferior to clavicle
Red - left lower ribs
Brown - 4th intercostal space
Signs of an MI on a ECG? Ans✓✓✓-Downsloping ST segment and pathologic Q
waves
What are the segments of the EKG? Ans✓✓✓-QRS complex - ventricular
depolarization
P - atrial depolarization
T - ventricular repolarization
ST segment - time between ventricular depolarization and repolarization
Length of: QRS complex, PR interval, QT interval, RR interval Ans✓✓✓-PR - 0.12-
0.2
QRS - 0.08-0.1
QT - 0.4-0.43
RR - 0.6-1
What are some normal ECG changes during exercise? Ans✓✓✓-Decreased R-R
interval
P wave magnitude increase
Decreased PR interval
