What are the 5 circumference points? - correct answer ✔✔- Arm (midpoint between acromion 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 - correct answer ✔✔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 - correct answer ✔✔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? - correct answer ✔✔- 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 - correct answer ✔✔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 - correct answer ✔✔Pros: very reliable, can highlight fat distribution
Cons: movement may disrupt image, expensive, exposure to radiation
Describe the process of taking BP - correct answer ✔✔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? - correct answer ✔✔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 - correct answer ✔✔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 - correct answer ✔✔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? - correct answer ✔✔Average pressure in arteries during one cardiac
cycle (65-110)
5 lead EKG - correct answer ✔✔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? - correct answer ✔✔Downsloping ST segment and pathologic Q waves
What are the segments of the EKG? - correct answer ✔✔QRS complex - ventricular depolarization
P - atrial depolarization
T - ventricular repolarization
ST segment - time between ventricular depolarization and repolarization
What are some normal ECG changes during exercise? - correct answer ✔✔Decreased R-R interval
P wave magnitude increase
Decreased PR interval
What are the time frames of the boxes on an ECG? - correct answer ✔✔Small box is 0.04 seconds
Big box is 0.2 seconds
Describe the process of Spirometry - correct answer ✔✔1. Breathe normally
2. Inspire completely and rapidly with a pause of ≤2 s at TLC
3. Expire with max effort until no air can be expelled while maintaining upright posture
4. Inspire with maximal effort until completely full
5. Repeat instructions as necessary, coaching vigorously
6. Repeat for a minimum of 3 maneuvers, usually no more than 8 for adults
Contraindications for Spirometry - correct answer ✔✔- MI/eye/sinus/ear surgery within 1-week
- Uncontrolled hypertension
- Significant arrhythmia
- Recent concussion
- Late term pregnancy
- Syncope related to expiration/coughing
- Avoid vaping/smoking/exercise within 1 hour
- Avoid intoxicants 8 hours prior
What is FVC? - correct answer ✔✔Forced vital capacity, total volume the patient can force ably exhale in
one breath
What is FEV1? - correct answer ✔✔Forced expiratory volume in 1 second
