  40. What is the weber test?
    • It is a test for lateralization. 
    • warp the running fork strongly and then place it on to of the pt's head  the midline and ask patient where they hear the sound. 
    • In a conductive loss, sound materializes to the DEFECTIVE ear.
  41. what is the Rinne test?
    • Place the butt of the mastoid eminence firmly. 
    • pt needs to tell when they don't hear the vibration. 
    • Then place the U part of the fork near the ear w/o touching it, pt. should tell you when they stop hearing it. 
    • It should be hear by air conduction 2x more that bone conduction.
  42. What to look for when examining the nose? what does blue, red, pink finding mean?
    • Look inside the nose and need to be able to see nice turbinates. 
    • Swollen, blue and boggy: allergies 
    • Read and swollen: infection, URI. 
    • Pink and moist: Normal
  43. what should be check in the mouth?
    • Number of teeth. Wisdom tooth is #1. Should be 32 teeth. 
    • Mucus membrane. 
    • Gingiva. 
    • gums. 
    • count caries and missing teeth.
    • tongue.
  44. what should be assess in the Oropharynx?
    • Palatine tonsiles (note the size- +1,2,3,4) 
    • Pharynx (pink color) 
    • Uvula (position) 
    • Soft palate (color) 
    • gag reflex (CN IX and X)
  45. how to examine for lymph nodes? what findings should be concerning?
    • Inspect head, neck, axillae, arm, and groin. 
    • Concerns: > 1cm, hard-fixed- nontender nodule.
