A nurse is preparing to suction secretions from a patient who has a new tracheostomy. Which of the following actions should the nurse plan to take?
Use a resuscitation bag with 80% oxygen prior to the procedure.
Select a suction catheter that is half the size of the lumen.
Place the end of the suction catheter in water-soluble lubricant.
Adjust the wall suction apparatus to a pressure of 170 mm Hg.
The Correct Answer is B
Choice A rationale: Using a resuscitation bag with 80% oxygen prior to the procedure is inappropriate. While pre-oxygenation is important before suctioning to prevent hypoxia, the oxygen concentration should be 100%, not 80%. Normal oxygen saturation levels are 95% to 100%. Pre-oxygenating with 100% oxygen ensures the patient maintains adequate oxygenation during the brief suctioning period. Using 80% oxygen does not fully optimize oxygen reserves for this purpose.
Choice B rationale: Selecting a suction catheter that is half the size of the tracheostomy lumen is appropriate. This size prevents excessive occlusion of the airway, ensuring adequate airflow during suctioning. The correct catheter size minimizes trauma to the tracheal mucosa and prevents hypoxia. The catheter should not exceed 50% of the tracheostomy diameter to maintain proper airway function, making this the correct action for safe and effective suctioning.
Choice C rationale
Placing the end of the suction catheter in water-soluble lubricant is not recommended. This could introduce bacteria into the airway and increase the risk of infection.
Choice D rationale
Adjusting the wall suction apparatus to a pressure of 170 mm Hg is not correct. The recommended suction pressure for adults is usually between 80 and 120 mm Hg. Suctioning at too high a pressure can cause trauma to the airway.

Correct Answer is B
Explanation
Choice A rationale
Inserting the suction catheter while the patient is swallowing is not the recommended technique for nasotracheal suctioning. This could cause discomfort and potentially lead to aspiration.
Choice B rationale
Applying intermittent suction when withdrawing the catheter is the correct technique for nasotracheal suctioning. This helps to remove secretions effectively while minimizing trauma to the nasal and tracheal mucosa.
Choice C rationale
Placing the catheter in a location that is clean and dry for later use is not a recommended practice. After suctioning, the catheter should be properly cleaned or disposed of to prevent infection.
Choice D rationale
Holding the suction catheter with their clean, non-dominant hand is not a recommended practice. The nurse should use clean gloves and proper hand hygiene when performing nasotracheal suctioning to prevent infection.
Correct Answer is C
Explanation
Choice A rationale
A lesion with uniform pigmentation is not typically a sign of skin malignancy. Most benign moles are uniform in color, including shades of tan, brown, and black.
Choice B rationale
The new appearance of petechiae, or small, pinpoint hemorrhages under the skin, is not typically associated with skin cancer. Petechiae can be a sign of a number of conditions, including certain infections, low platelet count, or certain medications.
Choice C rationale
A mole with an asymmetrical appearance is a potential indication of skin malignancy. Asymmetry, where one half of the mole does not match the other, is one of the ABCDEs (Asymmetry, Border irregularity, Color variation, Diameter greater than 6mm, and Evolving size, shape, or color) of melanoma detection.
Choice D rationale
The presence of a papule, a small, raised bump on the skin, is not necessarily indicative of skin cancer. Papules can be a sign of many different skin conditions, including acne, skin infections, or dermatitis.
