A nurse is assessing a client who has oxygen toxicity. Which of the following findings should the nurse expect?

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.

A. Pain in the affected leg could indicate worsening of cellulitis or a potential complication like deep vein thrombosis (DVT), but there is no immediate indication of a life-threatening condition. This client should be assessed, but may not be the top priority unless other signs of complications are present.

B. A serum calcium level of 10 mg/dL is within the normal range (8.5 to 10.5 mg/dL). A headache, while concerning, is not immediately life-threatening unless there are additional symptoms suggesting something more severe.

C.Reddish brown urine suggests hematuria, a symptom of glomerulonephritis. This could indicate ongoing kidney issues, but unless there are signs of severe kidney failure or systemic infection, this might not be the most urgent case.

D. A blood glucose level of 68 mg/dL is low and can lead to hypoglycemia, which can be immediately life-threatening if it progresses to severe hypoglycemia. Symptoms of hypoglycemia include confusion, dizziness, sweating, and can escalate to seizures or unconsciousness if not promptly treated.
