Mr. B is a 65-year old carpenter complaining of morning stiffness and pain in both his hands and left knee when he awakens in the morning. He notices some relief after a warm shower and getting dressed which takes about an hour or so.   On exam, the NP notices the presence of Heberden’s and Bouchard’s nodes.  There is no swelling or warmth of the metacarpophalangeal joints (MCPs) but some limited flexion of the DIPs and PIPs. There is no swelling or warmth of the left knee but there is some mild tenderness along the medial joint line. Which of the following is the most likely diagnosis for the hand and knee pain?

 After ruling out a cardiac origin in a patient presenting with atypical chest pain, the NP considers the likely causes of non-cardiac chest pain. An inexpensive, sensitive, and specific diagnostic test to determine if the patient is having GE reflux-induced non-cardiac chest pain is:
