17. (2pts) Which MOSFET amplifier type is best for voltage amplification?

18. (2pts) In a MOSFET amplifier operating in the active region, the small-signal output resistance, ro, is primarily due to:

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:

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:

What calculation is performed to find a patient’s maximum target heart rate for exercise electrocardiography?
