The nurse is caring for a client who has chronic renal disease and is receiving therapy with erythropoietin (epoetin alpha). Which of the following laboratory results should the nurse review as an indication of a therapeutic effect of this medication?

Leukocytes

Hemoglobin

Platelets

Brain Natriuretic peptide

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is B

Explanation

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).

A. Cardiac arrest B. Falling through the ice C. Head trauma D. Drug use

Correct Answer is A

Explanation

A. Cardiac arrest: Cardiac arrest is a complication of severe hypothermia, not a risk factor.

B. Falling through the ice: Major risk factor for accidental hypothermia due to immersion in cold water.

C. Head trauma: Impaired thermoregulation in the brainstem can cause hypothermia.

D. Drug use: Certain drugs (e.g., alcohol, sedatives) impair the body’s ability to regulate temperature, increasing hypothermia risk.
