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 B
Explanation
A. A client who has a prescription for insulin, and his premeal capillary blood glucose was 110 mg/dL, and his post-meal capillary blood glucose is now 160 mg/dL:
While changes in blood glucose levels are important to monitor, the described change is not as significant as a sudden drop in blood pressure. The blood glucose levels in this scenario are still within a reasonable range.
B. A client whose blood pressure at 0800 was 138/86 mm Hg, and at 1200 is 106/60 mm Hg:
This is the priority client. The significant drop in blood pressure raises concerns about hypovolemia or circulatory issues, which require immediate attention to prevent complications such as inadequate organ perfusion.
C. A client who reports pain as 4 on a scale of 1 to 10 at 0800 and now reports pain as 6:
Pain management is important, but the change in pain intensity from 4 to 6, while indicating an increase, may not be as urgent as addressing a significant drop in blood pressure. Pain assessment and management can be addressed after stabilizing the client with the acute change.
D. A client whose wound drainage at 0800 was sanguineous, and now it is serosanguineous:
Changes in wound drainage color can be important for assessing the healing process, but a shift from sanguineous to serosanguineous is generally within the expected progression of wound healing. It may not require immediate intervention as compared to a significant drop in blood pressure.
Correct Answer is A
Explanation
A. Increased anteroposterior diameter of the chest
In emphysema, there is often hyperinflation of the lungs and destruction of the alveolar walls, leading to loss of lung elasticity. This results in increased air trapping and a characteristic "barrel chest" appearance, with an increased anteroposterior diameter.
B. Petechiae on chest:
Petechiae are small, red or purple spots caused by bleeding into the skin. They are not commonly associated with COPD and emphysema.
C. Oxygen saturation level 96%:
Oxygen saturation level of 96% is within the normal range. While oxygen saturation can be affected in COPD, the value provided is not indicative of severe hypoxemia.
D. Respiratory alkalosis:
Respiratory alkalosis is not typically associated with COPD and emphysema. In fact, respiratory acidosis is more commonly seen in these conditions due to impaired gas exchange and retention of carbon dioxide.
