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 A
Explanation
A. This is a significant finding that warrants immediate notification. Changes in mental status in elderly patients can indicate a variety of issues, including infection (such as a urinary tract infection), dehydration, or other acute illnesses. Given that elderly patients are at higher risk for delirium and other cognitive changes, this finding should be taken seriously.
B. These vital signs are largely within normal limits for an elderly patient. While the blood pressure is on the higher side, the heart rate and respiratory rate are within acceptable ranges. Therefore, this does not warrant immediate notification unless other symptoms are present.
C. This statement is reassuring and suggests that the client is not experiencing complications related to the indwelling catheter, such as infection or obstruction. It does not indicate any need for immediate notification of the provider.
D. Cloudy urine with sediment can be indicative of a urinary tract infection (UTI) or other complications related to the indwelling catheter. While this finding is concerning and may require further evaluation, it is not as urgent as a change in mental status. It should still be reported to the healthcare provider but may not necessitate immediate action.
Correct Answer is B
Explanation
A. After a radical cystectomy, the client may have a urinary diversion (such as a stoma) and should be vigilant about monitoring urine output. Absence of urine output can indicate a serious issue, and notifying the provider is crucial.
B. This statement indicates a need for further clarification. After a radical cystectomy, clients typically do not resume normal voiding because the bladder is removed. Instead, they may have a urinary diversion or need to learn how to manage their new urinary output. Normal voiding as before surgery is not possible, so this statement reflects a misunderstanding of the procedure's implications.
C. After surgery, particularly abdominal surgery like a radical cystectomy, patients are often advised to take stool softeners to prevent constipation. Straining can increase the risk of complications and affect the surgical site, so this is a valid precaution.
D. Monitoring the surgical site for signs of infection, such as redness, swelling, or discharge, is an essential part of post-operative care. Clients should be educated on how to check their surgical site for any concerning changes.
