A nurse is reviewing the laboratory findings of a client who is taking erythropoietin. Which of the following results indicates the medication is effective?
Decreased white blood cells
Increased calcium
Increased hemoglobin
Decreased BUN
The Correct Answer is C
A. Decreased white blood cells: Erythropoietin specifically stimulates red blood cell production in the bone marrow. White blood cell counts are not directly affected by this medication, so a decrease would not indicate effectiveness.
B. Increased calcium: Calcium levels are unrelated to erythropoietin therapy. Changes in calcium do not reflect the medication’s ability to stimulate erythropoiesis.
C. Increased hemoglobin: Erythropoietin promotes red blood cell production, which increases hemoglobin and hematocrit levels. An elevation in hemoglobin indicates the medication is effectively stimulating erythropoiesis.
D. Decreased BUN: Blood urea nitrogen reflects kidney function and protein metabolism. While erythropoietin is often used in clients with chronic kidney disease, a decrease in BUN is not a direct measure of the drug’s effectiveness.

Correct Answer is B
Explanation
A. Methadone: Methadone is an opioid agonist used for opioid dependence and pain management. It does not treat the symptoms of alcohol withdrawal and is not indicated in this scenario.
B. Chlordiazepoxide: Chlordiazepoxide is a benzodiazepine commonly used to manage acute alcohol withdrawal. It reduces agitation, tremors, and the risk of seizures by enhancing GABAergic activity in the central nervous system.
C. Varenicline: Varenicline is used to aid smoking cessation by acting on nicotinic receptors. It does not alleviate alcohol withdrawal symptoms and is not part of standard alcohol withdrawal management.
D. Buprenorphine: Buprenorphine is a partial opioid agonist used for opioid use disorder. It is not effective in treating alcohol withdrawal and does not address the associated neurological excitability or risk of seizures.
