QUESTION 1 OF 2
Maximum HR is 170 and resting HR is 60 beats/min. Using 50% heart-rate reserve, what is the target HR? Calculation only—not a prescription.
A. 55 beats/min
Check answer
Have another look.
55 is half the reserve. You still need to add resting HR.
Best answer: C. 115 beats/min
Reserve: 170 − 60 = 110. Then 60 + (0.50 × 110) = 115 beats/min.
What this tests: Calculate a target using HRR.
B. 85 beats/min
Check answer
Have another look.
85 is 50% of maximum HR; that is a different calculation.
Best answer: C. 115 beats/min
Reserve: 170 − 60 = 110. Then 60 + (0.50 × 110) = 115 beats/min.
What this tests: Calculate a target using HRR.
C. 115 beats/min
Check answer
That’s right.
Reserve: 170 − 60 = 110. Then 60 + (0.50 × 110) = 115 beats/min.
What this tests: Calculate a target using HRR.
D. 145 beats/min
Check answer
Have another look.
145 does not follow the stated HRR calculation.
Best answer: C. 115 beats/min
Reserve: 170 − 60 = 110. Then 60 + (0.50 × 110) = 115 beats/min.
What this tests: Calculate a target using HRR.
QUESTION 2 OF 2
Which statement about exercise monitoring while taking a beta blocker is most accurate?
A. The medication can blunt the exercise HR response.
Check answer
That’s right.
Beta blockers can lower HR and alter its rise with activity. Use the appropriate monitoring plan and clinical response.
What this tests: Recognize a limitation of HR-based monitoring.
B. An age-predicted zone already accounts for the medication dose.
Check answer
Have another look.
Age-based formulas do not incorporate the individual medication response or dose.
Best answer: A. The medication can blunt the exercise HR response.
Beta blockers can lower HR and alter its rise with activity. Use the appropriate monitoring plan and clinical response.
What this tests: Recognize a limitation of HR-based monitoring.
C. An altered HR response makes perceived exertion unusable.
Check answer
Have another look.
An appropriately explained exertion scale can still contribute to monitoring alongside symptoms and other indicated measures.
Best answer: A. The medication can blunt the exercise HR response.
Beta blockers can lower HR and alter its rise with activity. Use the appropriate monitoring plan and clinical response.
What this tests: Recognize a limitation of HR-based monitoring.
D. Resting HR alone determines an appropriate exercise intensity.
Check answer
Have another look.
Resting HR alone does not establish exercise demand or an appropriate target.
Best answer: A. The medication can blunt the exercise HR response.
Beta blockers can lower HR and alter its rise with activity. Use the appropriate monitoring plan and clinical response.
What this tests: Recognize a limitation of HR-based monitoring.
