PTA 1010 FINAL EXAM QUESTIONS WITH
CORRECT ANSWERS.
3 reasons to measure Heart Rate
1. Assess cardiovascular health
2. Evaluate response to treatment/recovery capabilities
3. Determine patency
patency
indicates presence or absence of blood flow at point of pulse palpation (ateries/veins)
How to measure HR?
1. Manual Palpation
-radial artery
-carotid artery
2. Stethoscope
3. Pulse Oximeter
Resting heart rate normal age-related values
Adults (10+): 60-100 bpm
Infants/Children (0-9): 70-160 bpm
Bradycardia
slow heart rate (less than 60 bpm)
Tachycardia
fast heart rate, above 100 bpm
Target Heart Rate (THR)
HR an individual should achieve with respect to age/medical conditon
60-80% is target intensity
220-age x 60-80%
, Max heart rate
220-age
Karvonen Method
Max HR = 220 - age
HRR = Max HR - Resting HR
Target HR = (HRR x Intensity) + Resting HR
Why would a pulse not be present?
Arterial occlusion (blockage)
Edema
No pulse + no medical explanation = notify PT
Where to palpate for patency?
Popliteal region
Femoral artery
Dorsum of foot
Posterior Tibialis
Brachial Artery
Why measure blood pressure?
1. Determines vascular resistance to blood flow
2. Measure cradiac effectives to pump blood
systolic pressure
The blood pressure generated by the heart during contraction.
diastolic pressure
occurs when the ventricles are relaxed; the lowest pressure against the walls of an artery
Korotkoff sounds
