A nurse is assessing a client who has oxygen toxicity. Which of the following findings should the nurse expect?
Metallic taste in mouth
Facial flushing
Muscle twitching
Periorbital edema
The Correct Answer is C
A. Metallic taste in the mouth:
This is not a typical finding of oxygen toxicity. Metallic taste may be associated with other factors but is not a specific indicator of oxygen toxicity.
B. Facial flushing:
Facial flushing is not a typical finding in oxygen toxicity. It is more commonly associated with other conditions, such as certain allergic reactions or vasodilation.
C. Muscle twitching
Muscle twitching, also known as myoclonus, is a recognized symptom of central nervous system oxygen toxicity. High concentrations of oxygen, particularly at increased pressures, can cause neurotoxic effects leading to muscle twitching, dizziness, and even convulsions.
D. Periorbital edema:
Periorbital edema is not a common manifestation of oxygen toxicity. It is more commonly associated with conditions related to fluid balance or kidney function.

Correct Answer is A
Explanation
A. Fluctuation of the fluid level within the water seal chamber
Fluctuation of the fluid level within the water seal chamber indicates that the chest tube is functioning properly. This fluctuation is a normal finding and reflects the movement of air in and out of the pleural space during the respiratory cycle. As the patient inhales, the fluid level drops, and as they exhale, it rises.
B. Equal amounts of fluid drainage in each collection chamber:
Equal amounts of drainage may suggest a problem with the drainage system or that the chest tube is not effectively draining air or fluid from the pleural space.
C. Continuous bubbling within the water seal chamber:
Continuous bubbling in the water seal chamber may indicate an air leak, which is not a normal finding. It should be investigated further.
D. Absence of fluid in the drainage tubing:
The absence of fluid in the drainage tubing may suggest that the chest tube is not effectively draining fluid from the pleural space or that there is a blockage in the system. It requires assessment and intervention.
Correct Answer is B
Explanation
A. Instructions on how to change ventilator settings:
Ventilator settings are typically adjusted by respiratory therapists or healthcare providers based on the client's respiratory status. While nurses may be involved in monitoring, changing ventilator settings is not part of the routine nursing care bundle.
B. Instructions on mouth care
Mouth care is an important component of the ventilator care bundle to prevent ventilator-associated pneumonia (VAP). Proper oral hygiene, including regular mouth care, can help reduce the risk of infection.
C. Instructions to suction the client’s tracheostomy every 2 hr:
Suctioning frequency is determined based on the client's needs and is not a fixed component of the ventilator care bundle. Suctioning is performed as necessary to maintain airway patency.
D. Instructions to place the client in a supine position:
The positioning of the client may be individualized based on the clinical condition. However, placing the client in a supine position is not a fixed component of the ventilator care bundle. The emphasis is on practices that prevent complications associated with mechanical ventilation.
