Answer :
Final answer:
Throughout the procedure of nasopharyngeal suctioning, intermittent suction pressure should be used. This technique prevents potential damage and helps maintain the balance between intra-alveolar and intrapleural pressures.
Explanation:
While performing nasopharyngeal suctioning, the recommended technique to use throughout the procedure is D) Intermittent suction pressure.
The reason behind this is that intermittent suction avoids potential damage that can be caused by continuous suction pressure. This is important to prevent trauma to the patient's nasopharyngeal mucosa and to avoid causing a potential imbalance in the intrapleural and intra-alveolar pressures. Continuous, forceful, or pulsatile suction can lead to injuries, so these methods are generally not recommended.
Essentially, the pressure difference between the intra-alveolar and intrapleural pressures, also known as the transpulmonary pressure, is critical in ensuring the lungs remain inflated and functional. Using an incorrect suction pressure during nasopharyngeal suctioning could disrupt this delicate balance and cause harm to the patient.
