midway between the outer canthus and EAM
superior to the level of the EAM
posterior to the EAM
superior to the level of the EAM
Rationale: The central ray is directed 1-2 inches superior to the EAM (external auditory meatus) in order to include the vertex of the skull. The lateral skull must include the frontal bone, vertex, and occipital bone.

You have been called for a 79-year-old female complaining of shortness of breath. Due to the increased respiratory rate, cough, and production of discolored sputum, you are suspicious of pneumonia. A family member asks you how she can have pneumonia, when her temperature is only 97.9°F. Your best response is:
A) "It is not uncommon for the elderly to have pneumonia without the signs of high fever or chills." B) "You will have to ask the doctor because I cannot give out medical information." C) "There is less need for an increased body temperature since the elderly have a higher number of white blood cells." D) "Higher blood pressure, typically seen in the elderly, tends to inhibit the body from producing a fever."
