Why is respiration rate usually counted directly after taking the pulse rate, while the fingers are still on the wrist?

1. People may breathe more quickly if they know they are being observed

2. Respiration rate must always be measured by two healthcare providers

3. It ensures that the pulse rate and respiration rate are the same

4. Respiration rate is not affected by the presence of the fingers on the wrist

The correct answer is: People may breathe more quickly if they know they are being observed

Counting respiration rate immediately after the pulse rate, while maintaining the fingers on the wrist, is important because it helps obtain an accurate reading. When individuals are aware that they are being observed, they may alter their breathing patterns, often resulting in a faster or more irregular breathing rate. This alteration can skew the measurement of their normal respiration rate. By measuring it discreetly, healthcare providers can ensure that the individual is not conscious of the observation, thus allowing for a more genuine representation of their respiratory status. This method enhances accuracy and provides more reliable data for assessment and monitoring. The other options do not accurately capture the rationale behind this practice. For instance, respiration rate does not require two healthcare providers for measurement, nor is there a necessity for the two rates to be the same. Additionally, while fingers on the wrist may not directly impact respiration, the key factor is the awareness of being monitored, which could lead to potential variability in breathing.
