The client's arterial blood gases reveal the following results: pH 7.51, PaO2 80 mmHg, PaCO2 28 mmHg, HCO3 24 mEq/L, O2 saturation 92%. The nurse interprets this blood gas result as:

respiratory alkalosis.
metabolic alkalosis.
respiratory acidosis.
metabolic acidosis.
The Correct Answer is A
A. The elevated pH and decreased PaCO2 indicate that the respiratory system is causing alkalosis, typically due to hyperventilation (excessive breathing).
B. Metabolic alkalosis would be indicated by a high pH with a normal or high HCO3. Since the HCO3 level is normal and the PaCO2 is low, this does not fit the picture of metabolic alkalosis.
C. Respiratory acidosis would be characterized by a low pH and an elevated PaCO2 due to inadequate ventilation and accumulation of carbon dioxide. Here, the pH is high, and the PaCO2 is low.
D. Metabolic acidosis would be indicated by a low pH with a low HCO3. In this case, the pH is high, and the HCO3 is normal.

Correct Answer is B
Explanation
A.While it's important to gather information about the client's symptoms, the priority in this situation is to determine the underlying cause of the neurological symptoms. A CT scan can quickly identify if there's been a stroke or other brain injury.
B.This is the most appropriate and urgent intervention. A CT scan can rapidly identify if the client has had a stroke, which is a time-sensitive medical emergency. Early diagnosis and treatment are crucial for minimizing brain damage and improving outcomes.
C.t-PA is a medication used to dissolve blood clots in the brain, but it is only effective if given within a specific time window after the onset of stroke symptoms. Without a confirmed diagnosis of stroke from a CT scan, administering t-PA could be harmful.
D.While a speech pathologist may be involved in the client's care later on, the priority is to determine the underlying cause of the neurological symptoms and initiate appropriate treatment. A CT scan is essential for this purpose.
Correct Answer is C
Explanation
A. This response shows some awareness but does not indicate a sufficient understanding of the risks. Straight razors can pose a significant risk of cuts and bleeding, especially in a patient who has received t- PA, which can increase the likelihood of bleeding.
B. This response suggests a misunderstanding. Using multiple razor blades does not inherently reduce the risk of bleeding and could increase the chance of cuts or nicks. This response does not indicate an appropriate understanding of safety precautions related to t-PA.
C. This response indicates an understanding of safety precautions. Electric razors are safer for clients who are at risk of bleeding because they do not have sharp blades that can easily cause cuts. This choice minimizes the risk of injury while allowing for personal grooming.
D. While disposable razors may seem convenient, they still carry a risk of cuts and bleeding. This response does not reflect a full understanding of the precautions necessary for a client who has received t-PA, as it does not prioritize safety in the same way that using an electric razor does.
