The nurse is reviewing the laboratory findings for a 34-year-old woman who is scheduled for a Schilling's test for B12 deficiency anemia. Which result should the nurse report immediately to the primary care provider?

Choice A Reason
A hemoglobin level of 7.1 g/dL is significantly lower than the normal range, which is typically around 13.8 to 17.2 g/dL for men and 12.1 to 15.1 g/dL for women. This finding is concerning as it indicates severe anemia, which can be a life-threatening condition requiring immediate intervention. Anemia can lead to tissue hypoxia as the blood's capacity to carry oxygen is diminished. In the context of peripheral arterial disease, where blood flow is already compromised, anemia can exacerbate symptoms and increase the risk of ischemic events.

Choice B Reason
Ecchymosis, or bruising, on the client's upper extremities could be a result of the antiplatelet effects of aspirin, which inhibits platelet aggregation and prolongs bleeding time. While this is a concern and warrants monitoring, it is not as immediately life-threatening as severe anemia. However, it does indicate a risk of bleeding complications, which should be addressed by the healthcare provider.

Choice C Reason
A platelet count of 148,000/uL is at the lower end of the normal range, which is approximately 150,000 to 450,000 platelets per microliter of blood. This finding should be monitored, especially in the context of aspirin therapy, which can affect platelet function. However, it is not as critical as the low hemoglobin level.

Choice D Reason
Gastrointestinal discomfort is a common side effect of aspirin due to its irritation of the stomach lining. While this symptom can be uncomfortable and may lead to more serious gastrointestinal issues such as ulcers or bleeding, it is typically not as urgent as severe anemia. The client should be evaluated for potential gastrointestinal complications of aspirin therapy.

Choice A Reason:
Weekly aerobic exercise at a gym is generally beneficial for joint health and is not a predisposing factor for osteoarthritis. Regular physical activity helps maintain joint flexibility, muscle strength, and overall health, which can actually help prevent the development of osteoarthritis.

Choice B Reason:
Vitamin D deficiency has been associated with an increased risk of osteoarthritis. Vitamin D is essential for bone health, and a deficiency can lead to changes in bone structure and strength, potentially contributing to the development and progression of osteoarthritis.

Choice C Reason:
A weight of less than 60 kg does not typically predispose an individual to osteoarthritis. In fact, maintaining a healthy weight can reduce the risk of developing osteoarthritis, as excess body weight can increase the stress on joints.

Choice D Reason:
Trauma can lead to post-traumatic osteoarthritis, which is a form of osteoarthritis that develops after an injury to a joint. Traumatic injuries can damage the cartilage and bone, leading to degenerative changes and osteoarthritis.
