A nurse is caring for a client with the following Arterial Blood Gases (ABG) pH 7.48, PaCO2 53, and HCO3 31. How would these be interpreted?

Respiratory alkalosis

Partially Compensated Metabolic Alkalosis

Metabolic Acidosis

Fully Compensated Respiratory Acidosis

Answer and Explanation

The Correct Answer is B

A. Respiratory Alkalosis: Would have low PaCO2 (<35 mmHg), not high.

B. Partially Compensated Metabolic Alkalosis: The pH is high (alkalosis), and the HCO3 is elevated, which indicates metabolic alkalosis. The PaCO2 is high, meaning the lungs are attempting to compensate by retaining CO₂ to lower the pH. Because the pH is still abnormal, this is partial compensation.

C. Metabolic Acidosis: Would have low pH and low HCO3 (<22 mEq/L).

D. Fully Compensated Respiratory Acidosis: The primary problem is metabolic, not respiratory.

Correct Answer is D

Explanation

A. “This is called a thrill and it means that your fistula is not working.” A thrill is a normal finding and means the fistula is functioning properly.

B. "This is not a normal sign; we will call your provider right away.” A lack of thrill is abnormal, not the presence of one.

C. "This is called a bruit and it shows that your fistula is patent." The thrill is felt and the bruit is heard.

D. "This is called a thrill and it means that your fistula is patent." A thrill (vibration) is a normal finding in an AV fistula and indicates adequate blood flow. A bruit (whooshing sound) is heard on auscultation and also confirms patency.

A. Oliguria B. Temperature 36.1° C (97.0° F) C. Weight loss D. Insomnia

Correct Answer is A

Explanation

A. Oliguria: Reduced urine output (oliguria) can indicate acute rejection due to decreased renal function. Other signs include fever, hypertension, graft tenderness, and swelling.

B. Temperature 36.1° C (97.0° F): Rejection often causes fever, not a low temperature.

C. Weight loss: Weight gain (fluid retention) is more common with rejection.

D. Insomnia: Insomnia is not a direct sign of rejection.
