The patient's symptoms and physical examination findings are suggestive of hyperthyroidism. The TSH test is a priority in the work-up as it will help to confirm the diagnosis of hyperthyroidism. The other options are not as relevant in this scenario. The ACTH challenge test is used to evaluate adrenal function, which is not a concern in this case. Atrial fibrillation is a potential complication of hyperthyroidism, but it is not a diagnostic test. Fasting blood glucose may be important in evaluating for diabetes, but it is not the priority in this case.
