A client with Addison's disease started taking hydrocortisone in a divided daily dose last week. It is most important for the nurse to monitor which serum laboratory value?

Choice A reason: Obtaining a prostate-specific antigen (PSA) blood level test is important for screening and monitoring prostate health but does not directly reduce the risk factors for benign prostatic hyperplasia (BPH). PSA tests can help in early detection of prostate issues, but they are not preventive measures.

Choice B reason: Taking vitamin supplements is not specifically proven to reduce the risk of BPH. While maintaining overall nutritional health is important, there is no direct evidence that vitamin supplements alone can prevent BPH. It's better to focus on a balanced diet and healthy lifestyle choices.

Choice C reason: Consuming a high-protein diet does not specifically reduce the risk of BPH. While protein is an essential nutrient for overall health, there is no clear evidence that it has a direct impact on preventing BPH. A balanced diet that includes a variety of nutrients is more beneficial for general health and well-being.

Choice D reason: Increasing physical activity is one of the recommended lifestyle changes to reduce the risk of BPH. Regular physical activity can improve overall health, help maintain a healthy weight, and potentially reduce the risk of BPH. Physical activity is associated with better prostate health and can help mitigate some of the risk factors associated with BPH, such as obesity and sedentary lifestyle.

Choice A reason: A complete blood count (CBC) is the most relevant laboratory value to review for a client with iron deficiency anemia who reports increased fatigue. The CBC will provide important information about the levels of red blood cells, hemoglobin, and hematocrit, which are directly affected by iron deficiency. Monitoring these values will help determine if the client’s anemia is worsening or if the iron supplements are not effectively improving the blood count.

Choice B reason: The platelet count is part of a CBC but is not directly related to the symptoms of fatigue in iron deficiency anemia. While platelet levels are important for assessing clotting function, they do not provide the necessary information about red blood cell levels or hemoglobin concentration that are central to diagnosing and managing anemia.

Choice C reason: Serum electrolytes are important to monitor for overall health and hydration status, but they are not specifically related to the client’s anemia or the symptom of fatigue. Electrolyte imbalances typically do not cause fatigue related to anemia, so this is not the primary laboratory value to review in this context.

Choice D reason: Liver enzymes are important for assessing liver function and potential liver damage, but they are not directly related to iron deficiency anemia or the symptom of fatigue. While it is important to monitor liver health, especially if the client is on medications that affect the liver, the complete blood count is more relevant to the symptoms described.
