A nurse is reviewing the ABGs of a client who has pneumonia. The nurse should identify which of the following findings is an indication of respiratory acidosis.

Choice A rationale:

The nurse's first priority in this situation should be to close the pinch clamp on the central venous catheter (CVC). This will prevent air from entering the client's vascular system and causing an air embolism, which can lead to serious complications. Once the clamp is closed, the nurse can then proceed with further assessments and interventions.

Choice B rationale:

Obtaining a prescription for stat ABGS (Arterial Blood Gas Studies) is not the first action the nurse should take in this situation. While ABGS may be relevant later to assess the client's respiratory status, the immediate concern is to prevent air embolism by closing the disconnected IV tubing.

Choice C rationale:

Placing the client in the left Trendelenburg position is not the first priority in this situation. The Trendelenburg position is used to increase venous return and is typically indicated in cases of hypotension or shock. Closing the clamp to prevent an air embolism should be the nurse's initial action.

Choice D rationale:

Checking the tubing for the placement of a locking adaptor is not the first action the nurse should take. While it is essential to ensure that the IV tubing is properly connected and secured, preventing the air from entering the CVC should take precedence in this urgent situation.

Choice A rationale:
Increasing the intake of high-fiber foods is not relevant to addressing the client's dry mouth caused by benztropine. High-fiber foods are commonly recommended for managing constipation, a symptom often associated with Parkinson's disease, but it does not address the issue of dry mouth.
Choice B rationale:
Chewing sugarless gum can stimulate saliva production and help alleviate dry mouth. However, it is not the most appropriate recommendation for a client taking benztropine, as gum-chewing may interfere with the effectiveness of the medication or exacerbate other symptoms.
Choice C rationale:
Moistening the mouth with lemon-glycerin swabs is the most suitable recommendation for a client experiencing dry mouth due to benztropine. Lemon-glycerin swabs can help increase saliva production and provide relief from the discomfort of dry mouth without interfering with the medication's efficacy.
Choice D rationale:
Rinsing the mouth with nystatin is used to treat fungal infections in the mouth (oral thrush) and is not relevant to address the side effect of dry mouth caused by benztropine.
