An adult male with chronic anemia is experiencing increased fatigue and occasional palpitations at rest. Which laboratory data would the nurse identify as consistent with these symptoms?
RBC Count of 4,500,000/mL.
Normal red blood cell (RBC) indices.
Hemoglobin of 8.2 g/dL (82 g/L).
Hematocrit (Hct) 38%.
The Correct Answer is C
Choice A reason: An RBC count of 4,500,000/mL is within the normal range and would not typically cause symptoms of anemia.
Choice B reason: Normal RBC indices do not indicate anemia and would not explain the symptoms.
Choice C reason: A hemoglobin level of 8.2 g/dL is below the normal range and would be consistent with symptoms of anemia such as fatigue and palpitations.
Choice D reason: A hematocrit of 38% is within the normal range for adult males and would not typically be associated with anemia symptoms.

Correct Answer is ["A","B","D"]
Explanation
Choice A reason: Genetics play a significant role in the development of multiple sclerosis (MS). While MS is not directly inherited, certain genetic markers can increase susceptibility. Studies have shown that individuals with a first-degree relative with MS have a higher risk compared to the general population.
Choice B reason: Environmental factors, such as low vitamin D levels, smoking, and possibly viral infections, are believed to contribute to the risk of developing MS. Geographic location, particularly living further from the equator, has also been associated with a higher incidence of MS, which may be related to sun exposure and vitamin D synthesis.
Choice C reason: While upper respiratory infections can trigger exacerbations in individuals with existing MS, they are not identified as a direct contributing factor to the development of the disease itself.
Choice D reason: MS is considered an autoimmune disorder where the immune system mistakenly attacks the central nervous system. This immune-mediated process targets the myelin sheath, leading to inflammation and characteristic lesions.
Choice E reason: Urinary tract infections are a common complication in individuals with MS due to bladder dysfunction, but they are not a contributing factor to the development of MS.
