Hint : 🫀Aging lowers heart rate max.

Correct Answers:

  • Maximum heart rate of 145 beats per minute with exercise


Rationale :

💎In older adults, the maximum heart rate declines with age due to reduced beta-adrenergic responsiveness and physiologic cardiac changes.

💎The common formula 220 – age gives expected max HR; at age 75, it is ~145 bpm.

💎This change is normal and does not necessarily indicate pathology.

💎Other expected age-related cardiovascular changes include decreased baroreceptor sensitivity and increased vascular resistance, not improvement.

💎Nurses use this information when assessing exercise tolerance and planning activity regimens.
