pH 7.37. PaCO2:45, PO2 91, HCO3 24

pH 7.48. PaCO2 32, PO2 94. HCO3 22

Answer and Explanation

The Correct Answer is B

A. pH 7.30, PaCO₂ 38, HCO₃ 15: Metabolic acidosis (low HCO₃, normal PaCO₂).

B. pH 7.32, PaCO₂ 56, PO₂ 84, HCO₃ 26: The client has respirations of 8/min, which indicates hypoventilation → CO₂ retention → respiratory acidosis. pH 7.32 indicates acidosis. PaCO₂ 56 mmHg - Elevated CO₂ (hypercapnia), confirming respiratory acidosis. HCO₃ 26- Normal bicarbonate suggests that compensation has not yet occurred

C. pH 7.37, PaCO₂ 45, HCO₃ 24: Normal ABG values.

D. pH 7.48, PaCO₂ 32, HCO₃ 22: Respiratory alkalosis (low PaCO₂ due to hyperventilation, not hypoventilation).

Correct Answer is C

Explanation

A. Administer scheduled medications: Some medications (e.g., antihypertensives, water-soluble vitamins, and antibiotics) should be held before dialysis to prevent removal during treatment.

B. Explain that dialysis occurs via the peritoneum: This describes peritoneal dialysis, not hemodialysis.

C. Weigh the client to determine a baseline for comparison: Pre-dialysis weight is crucial to determine fluid removal needs during dialysis. Weight differences before and after dialysis indicate fluid loss or retention.

D. Obtain a serum creatinine to determine kidney function: Serum creatinine levels are monitored regularly but are not a required step before every dialysis session.

A. "We'll find out if any medications, such as steroids, are interfering with your kidney function." B. "This test will tell your doctor how your kidneys are functioning.” C. "This test will tell if you have severe renal impairment or a disease.” D. "You'll have to ask your doctor.”

Correct Answer is B

Explanation

A. "We'll find out if any medications, such as steroids, are interfering with your kidney function." Some medications affect kidney function, but creatinine primarily measures kidney efficiency, not drug interactions.

B. "This test will tell your doctor how your kidneys are functioning." Serum creatinine is a key indicator of kidney function. It measures how well the kidneys are filtering waste products.

C. "This test will tell if you have severe renal impairment or disease." Creatinine can be elevated in mild, moderate, or severe kidney dysfunction, not just in severe disease.

D. "You'll have to ask your doctor." The nurse should provide basic health education to the client.
