Which pulse reading is outside the normal range for elderly patients?

The normal resting heart rate for elderly patients typically ranges from 60 to 100 beats per minute. In this case, a pulse reading of 50 beats per minute is considered bradycardia, which is below the normal range.

Bradycardia can be a concern, especially in older adults, as it may indicate underlying health issues or a response to medications. It's important to evaluate the context in which this pulse reading occurs, including any symptoms the patient may be experiencing.

In contrast, pulse readings of 72 beats per minute, 89 beats per minute, and 65 beats per minute all fall within the normal range for elderly patients, indicating a healthy heart rate for maintaining adequate circulation and oxygenation to the body's tissues.
