Final answer:
Pulse oximetry is not a monitor of a patient's ventilation. Visualization of chest excursions, capnography, and auscultation of breath sounds are all methods that can be used to monitor a patient's ventilation.
Step-by-step explanation:
The correct answer is A) Pulse oximetry. Pulse oximetry is a method used to measure the oxygen saturation of the blood and the patient's heart rate. It is not directly related to monitoring a patient's ventilation. Visualization of chest excursions, capnography, and auscultation of breath sounds are all methods that can be used to monitor a patient's ventilation.
