A nurse is suctioning the airway of a client who is receiving mechanical ventilation via an endotracheal tube. Which of the following findings should the nurse identify as an indication that the suctioning has been effective?
Thinning of mucous secretions
Decreased peak inspiratory pressure
Presence of a productive cough
Flattening of the artificial airway cuff
The Correct Answer is B
Choice A reason
While thinning of secretions can be a positive sign, it's not always visible. A decrease in peak inspiratory pressure is a more objective indicator of improved airway patency.
Choice B reason.
Peak inspiratory pressure is the maximum pressure required to push air into the lungs. If suctioning is effective, it will remove secretions and reduce airway resistance, leading to a decrease in peak inspiratory pressure.
Choice C reason:
While a productive cough can indicate that secretions are being moved, it doesn't directly measure the effectiveness of suctioning.
Choice D reason:
Flattening of the artificial airway cuff: Flattening of the artificial airway cuff is not a relevant indicator of the effectiveness of suctioning. The cuff of an endotracheal tube is inflated to prevent air leaks around the tube and to maintain proper ventilation. It is not directly related to the effectiveness of suctioning.

Correct Answer is B
Explanation
A. This is an incorrect action. Inserting air in the tube and listening for gurgling sounds in the epigastric area is not a reliable method to confirm NG tube placement, as it can produce false-positive results due to air entering the stomach or intestines.
B. This is a correct action. Aspirating contents from the tube and verifying the pH level is a valid method to confirm NG tube placement, as gastric contents typically have a pH of less than 5.5, while intestinal or respiratory contents have a higher pH.
C. This is an incorrect action. Reviewing the medical record for previous x-ray verification of placement is not sufficient to confirm NG tube placement, as the tube can migrate or become dislodged after insertion. X-ray verification should be done initially and whenever there is doubt about the tube's position.
D. This is an incorrect action. Auscultating the lungs for adventitious breath sounds is not a specific method to confirm NG tube placement, as it can indicate other conditions such as pneumonia or pulmonary edema. It can also miss signs of respiratory complications due to NG tube misplacement, such as pneumothorax or bronchial obstruction.
Correct Answer is C
Explanation
A. Incorrect. The client does not have respiratory alkalosis because respiratory alkalosis is characterized by a low PaCO2 (less than 35 mm Hg) and a high pH (greater than 7.45).
B. Incorrect. The client does not have metabolic alkalosis because metabolic alkalosis is characterized by a high HCO3 (greater than 26 mEq/L) and a high pH (greater than 7.45).
C. Correct. The client has respiratory acidosis because respiratory acidosis is characterized by a high PaCO2 (greater than 45 mm Hg) and a low pH (less than 7.35).
D. Incorrect. The client does not have metabolic acidosis because metabolic acidosis is characterized by a low HCO3 (less than 22 mEq/L) and a low pH (less than 7.35).
