Question 1

What equipment is needed to perform nasopharyngeal suctioning?

Accepted Answer

Nasopharyngeal suctioning requires a suction machine with adjustable pressure settings, sterile suction catheters of appropriate size, sterile gloves, water-soluble lubricant, sterile saline, personal protective equipment including mask and goggles, and potentially an oxygen delivery system. A resuscitation bag with mask should also be available if needed for emergency support during the procedure.

Question 2

Why is patient positioning important before nasopharyngeal suctioning?

Accepted Answer

Placing the patient in a semi-Fowler's position reduces the risk of aspiration and aids breathing by allowing secretions to drain more effectively. This positioning also facilitates easier catheter insertion and helps maintain airway patency during the procedure, improving both safety and procedural effectiveness.

Question 3

How should the suction catheter be inserted into the nasopharynx?

Accepted Answer

The nurse gently inserts the lubricated catheter into one nostril, aiming posteriorly and slightly downward along the floor of the nasal cavity, advancing it 5-6 inches to reach the pharynx without applying suction. Gentle insertion without suction reduces trauma to the sensitive nasal mucosa and prevents nosebleeds or other injuries.

Question 4

What suction pressure settings and duration are recommended for nasopharyngeal suctioning?

Accepted Answer

Set the suction machine pressure between 100 to 120 millimeters of mercury to efficiently clear secretions. Limit suction application to 10-15 seconds to prevent hypoxemia. Apply intermittent suction while gently rotating and withdrawing the catheter to avoid excessive negative pressure in one spot, which could cause trauma.

Question 5

How does pre-oxygenation help during nasopharyngeal suctioning?

Accepted Answer

If the patient is on supplemental oxygen, increase the flow rate before and after suctioning to prevent hypoxia, which can occur during suctioning due to temporary removal of the oxygen supply. Pre-oxygenation maintains adequate oxygen levels and reduces the risk of complications during the procedure.

Question 6

What steps should be taken after nasopharyngeal suctioning is complete?

Accepted Answer

After suctioning, flush the catheter with saline to clear secretions. Immediately reassess the patient's respiratory status and oxygen saturation. Offer tissues and assist the patient in cleaning around the nose and mouth if needed. Document the procedure, including the amount and characteristics of secretions, any complications, and the patient's tolerance.

Question 7

Why is maintaining sterile technique essential during nasopharyngeal suctioning?

Accepted Answer

Maintaining sterile technique prevents nosocomial infections by avoiding introduction of harmful pathogens into the airway. The nurse must don sterile gloves, open the suction catheter package carefully, and maintain asepsis throughout the procedure. Proper catheter preparation and sterility reduce the risk of infection and airway complications.
