The nurse reports that the client has dyspnea when ambulating. The nurse is most likely to have assessed which of the following?
In the figure below, which number indicates the client’s oxygen saturation as measured by pulse oximetry? _____________
Explanation
One of the key components of vital signs measurement is oxygen saturation (SpOâ‚‚), which reflects the percentage of hemoglobin molecules carrying oxygen in the blood. This value is measured noninvasively using a pulse oximeter and is essential for assessing respiratory function and oxygen delivery.
Rationale for correct answer:
4. 97%: This is the SpOâ‚‚ or oxygen saturation reading from pulse oximetry. It represents the percentage of oxygen-bound hemoglobin and is essential in monitoring respiratory function.
Rationale for incorrect answers:
1. 121 mmHg: This is the systolic blood pressure, the pressure in arteries when the heart contracts. It is not related to oxygen saturation.
2. 95 mmHg: This is the MAP (Mean Arterial Pressure), which reflects average blood pressure during a cardiac cycle.
3. 87 BPM: This value indicates the heart rate in beats per minute (BPM).
5. 84 mmHg: This is the diastolic blood pressure, the pressure in arteries when the heart is at rest.
