The client has just returned from OR with respirations of 8 per minute. What set of ABG's would the nurse expect to see?

pH 7.30. PaCO2 38 P02 92, HCO3 15

pH 7.32. PaCO2 56, PO2 84, HCO3 26

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 A

Explanation

A. BUN 45 mg/dL and creatinine 8 mg/dL: In CKD, BUN (> 20 mg/dL) and creatinine (> 1.2 mg/dL) are significantly elevated due to reduced kidney function. A creatinine of 8 mg/dL indicates severe renal impairment.

B. BUN 10 mg/dL and creatinine 0.3 mg/dL: Too low for CKD, suggestive of normal renal function.

C. BUN 8 mg/dL, creatinine 0.7 mg/dL: Normal values.

D. BUN 23 mg/dL, creatinine 1.0 mg/dL: Mild elevation, but not consistent with CKD severity.

A. Leukocytes B. Hemoglobin C. Platelets D. Brain Natriuretic peptide

Correct Answer is B

Explanation

A. Leukocytes: Erythropoietin does not affect white blood cell (WBC) production.

B. Hemoglobin: Erythropoietin stimulates red blood cell (RBC) production in the bone marrow. Clients with chronic kidney disease (CKD) develop anemia due to decreased natural erythropoietin production. A therapeutic response is seen as an increase in hemoglobin levels.

C. Platelets: Erythropoietin does not stimulate platelet production (thrombopoiesis).

D. Brain Natriuretic Peptide (BNP): BNP is a marker for heart failure, not erythropoiesis.
