Final answer:
During a patient's secondary assessment, an EMT evaluates the respiratory rate, tidal volume, and obtains a pulse oximetry reading as part of the baseline vitals for respirations.
Step-by-step explanation:
During the secondary assessment of a patient, an EMT (Emergency Medical Technician) will evaluate several aspects of respiration as part of the baseline vitals. This includes assessing the rate of breathing, which is the respiratory rate, or how many breaths are taken per minute. The average resting respiratory rate for adults is typically 12-15 breaths per minute. The tidal volume, which is the amount of air inhaled or exhaled during a normal breath, is also observed, as variations can indicate potential respiratory issues. Lastly, a pulse oximetry reading is obtained which measures the oxygen saturation of the blood, providing insights into the patient's oxygenation status. Therefore, the correct elements assessed during the baseline vitals for respirations would be 1) Rate, tidal volume, and pulse ox reading.
