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:

A 48-year old male patient was diagnosed with Type 2 DM 4 months ago.  His A1c at the time was 8.1%.  He agreed to work on lifestyle changes and has been walking 2 miles daily, has cut back on his carbohydrate intake, and has lost 15 pounds (current BMI=30.9).  His recent A1c= 7.2%. Current BP = 132/78.  His recent lipid profile shows mild hypercholesterolemia with a total cholesterol =210, LDL-c = 108.   Serum creatinine = 0.64 and GFR=61.  The NP congratulates him on his efforts, discusses his test results and the recommendations for management to reduce the risk for diabetes-associated co-morbidities, and plan of care with him.  The patient is in agreement with the plan of care. The NP will order: (Select All That Apply)

A 28 year old female with a history of hypothyroidism, and who is a probation officer, presents to the office with a several month history of “shaking in my hands especially the right one”.  She tells the NP she is concerned because she carries a weapon and is worried her target skills will be affected which can affect her job. She also relates her brother “has the shakes too” but he never went to see a health care provider about it. She is taking levothyroxine 50 micrograms daily. The last TSH 3 months ago was 2.1 and B12 = 600 pg/mL. The most likely diagnosis is:
