Correct Answer is A

Explanation

A. This is because the patient's blood pressure of 98/66 mm Hg, while on the lower side, may be normal for them. It's important to compare it to their baseline to determine if there has been a significant change.
B. The blood pressure is within a normal range for an adult, so immediate notification of hypotension is not required.
C. This can be done after determining if there is a significant change from the baseline.
D. The pulse is not bradycardic (it is within a normal range), so there is no immediate need to notify the doctor regarding bradycardia.

A. measuring the oxygenated hemoglobin through a capillary bed. B. assessing the amount of blood passing through the sensor. C. assessing the relative warmth of the skin on the monitored part. D. measuring the respirations to the blood pressure via infrared rays.

Correct Answer is A

Explanation

A. Pulse oximetry works by using light absorption to measure the oxygen saturation of hemoglobin in the blood, which typically occurs through the capillary bed in areas like the finger or earlobe.
B. The pulse oximeter does not measure the amount of blood passing through the sensor directly, but rather the oxygen content of the blood.
C. The pulse oximeter does not assess the warmth of the skin as a mechanism for measuring oxygenation.
D. Pulse oximeters measure oxygen saturation levels, not the respiratory rate or blood pressure.
