Which of the following assessments would be least indicative of respiratory distress?

The assessment that is least indicative of respiratory distress is normal oxygen saturation. In a scenario of respiratory distress, one would typically expect to see abnormal oxygen levels due to impaired gas exchange, which would manifest as low oxygen saturation readings. Normal oxygen saturation indicates that the body is effectively oxygenating the blood, suggesting that the individual is not in respiratory distress at that moment.

In contrast, audible wheezing, increased pulse rate, and shallow breathing are all associated with respiratory distress. Wheezing indicates obstruction in the airways, which can signify problems like asthma or bronchospasm. An increased pulse rate often accompanies respiratory distress as the body tries to compensate for low oxygen levels or increased work of breathing. Shallow breathing may reflect inadequate ventilation and can lead to poor oxygen exchange, indicative of distress. Hence, normal oxygen saturation stands out as not reflecting a state of respiratory distress and is why it is the correct choice in this context.
