A nurse is caring for a client who has pneumonia with dyspnea. The client's ABG results are pH 7.30, PaCO2 50 mm Hg, HCO3 26 mEq/L. The nurse should recognize that the client has which of the following acid-base imbalances?

The correct answer is choice B, a client who had abdominal surgery 2 days ago and the incision line is separating. This client requires immediate attention as a separating incision can indicate wound dehiscence or evisceration, which are surgical emergencies. Choice A is incorrect because although C. difficile is a serious infection, liquid stools are a common symptom and do not require immediate attention. Choice C is incorrect because intermittent coughing up clear sputum is a normal finding for a client with a tracheostomy, and does not indicate a change in the client's condition. Choice D is incorrect because the client fell 12 hours ago and reports pain as 4 on a scale of 0 to 10, which indicates a low level of pain.

Choice A: A client who has Clostridium difficile and has liquid stools is incorrect because although C. difficile is a serious infection, liquid stools are a common symptom and do not require immediate attention.

Choice C: A client who has a chronic tracheostomy and is intermittently coughing up clear sputum is incorrect because intermittent coughing up clear sputum is a normal finding for a client with a tracheostomy, and does not indicate a change in the client's condition.

Choice D: A client who fell 12 hours ago and reports pain as 4 on a scale of 0 to 10 is incorrect because the level of pain is low and does not require immediate attention.

Yankauer catheter. A Yankauer catheter is a suction device used for oral suctioning. It is important for this client to have access to a Yankauer catheter for safe and effective suctioning of secretions from the mouth.

Option A is incorrect because an Oropharyngeal airway is used to maintain or open the airway.

Option B is incorrect because the water-soluble lubricant is used for lubricating the suction catheter during suctioning.

Option D is incorrect because sterile gloves are not routinely needed for suctioning.

Reasons why the other options are not answered: Option A: An oropharyngeal airway is not used for suctioning but is used to maintain an open airway in an unconscious patient. Option B: Water-soluble lubricant is used for lubricating the suction catheter during suctioning. Option D: Sterile gloves are not routinely needed for suctioning.
