Nuclear medicine thyroid scans are useful to evaluate the functional status of thyroid nodules in patients who are hyperthyroid.

The main identifiable risk associated with reducing or discontinuing acid suppression therapy is an increased symptom burden.

Although CT is accurate in the evaluation of suspected appendicitis in the pediatric population, ultrasound is nearly as good in experienced hands.

Nuclear medicine thyroid scanning does not conclusively determine whether thyroid nodules are benign or malignant.

Cold nodules on thyroid scans will still require biopsy.

Currently there are no formal practice protocols to address deactivation; fewer than 10% of hospices have official policies.

Advance care planning discussions should include the option of deactivating the implantable cardioverter-defibrillator when it no longer supports the patient’s goals.

Published guidelines provide clear indications for the use of telemetric monitoring in patients, which are contingent upon frequency, severity, duration, and conditions under which the symptoms occur.

Inappropriate use of telemetric monitoring is likely to increase cost of care and produce false positives potentially resulting in errors in patient management.

Skin or serum-specific Ig E testing for inhalants or foods is not indicated, unless there is a clear history implicating an allergen as a provoking or perpetuating factor for urticaria.

There is little evidence that detection of coronary artery stenosis improves health outcomes in asymptomatic patients at low risk of coronary heart disease.

Asymptomatic, low-risk patients account for up to 45% of unnecessary “screening.” Testing should be performed only when the following findings are present: diabetes in patients older than 40 years; peripheral arterial disease; or greater than 2% yearly risk of coronary heart disease events.
