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 A
Explanation
A. The patient’s paralyzing agent dose is adequate, but needs to be given more often.
In a Train-of-four (TOF) assessment, four stimuli are delivered in rapid succession, and the response is observed. The number of twitches in the patient's thumb indicates the degree of neuromuscular blockade. In this case, if the patient's thumb twitches three times, it suggests that there is still some residual neuromuscular blockade, and the paralyzing agent dose is adequate. However, the frequency of administration may need to be increased to maintain the desired level of paralysis or neuromuscular blockade.
B. The patient’s paralyzing agent dose is too low and needs to be increased:
This would be indicated if there were fewer than three twitches in response to the TOF assessment.
C. The patient’s paralyzing agent dose is appropriate and does not need to be changed:
The response of three twitches suggests that there is still some neuromuscular blockade, so the dose or frequency may need adjustment.
D. The patient’s paralyzing agent dose is too high and needs to be reduced:
If there were no twitches or a complete absence of twitches, this might suggest an excessive dose. However, three twitches indicate some degree of neuromuscular blockade.
