------------------------------------------------ A portable or fixed suctioning unit should have:

A. Only a Yankauer tip
B. Yankauer tip and tonsil tip
C. Yankauer tip and nasopharyngeal tip
D. Yankauer tip, tonsil tip, and tracheostomy tip

A portable or fixed suctioning unit should include a Yankauer tip, tonsil tip, and tracheostomy tip for comprehensive management of patient airways in various situations, including oral, oropharyngeal, and tracheostomy suctioning.

Explanation:

The correct answer is d) Yankauer tip, tonsil tip, and tracheostomy tip. A comprehensive suctioning unit is equipped to handle various situations that may require the removal of secretions or blockages from a patient's airway. The Yankauer tip is typically used for oral suctioning and is designed to effectively suction secretions without causing damage to the surrounding tissue. The tonsil tip is used for suctioning in the oropharyngeal area, specifically around the tonsils, pharyngeal tonsil, and the nasopharynx. Lastly, the tracheostomy tip is essential for patients with a tracheostomy to maintain a clear airway by removing secretions directly from the tracheostomy tube.
