Final answer:
To prevent hypoxia with suctioning, it is best to suction in a controlled and gentle manner. Aggressive suctioning, less frequent suctioning, or stopping suctioning altogether would not address the issue of thick mucus causing hypoxia.
Step-by-step explanation:
To prevent hypoxia with suctioning, the best approach would be to suction in a controlled and gentle manner (option C). Suctioning more aggressively (option A) can lead to tissue trauma and further airway obstruction. Suctioning less frequently (option B) may not adequately clear the airway. Stopping suctioning altogether (option D) would not address the issue of thick mucus causing hypoxia.
When suctioning, it is important to use a gentle technique to avoid damaging the airway. This involves inserting the suction catheter only as far as necessary and applying suction intermittently while withdrawing the catheter. This allows for the removal of mucus without compromising the patient's oxygenation.
