You have been called to the home of an elderly woman who is unable to get out of bed without “passing out.” After completing a primary survey, the EMR is advised that she has been experiencing vomiting and diarrhea for the last two days. What is the likely cause of her inability to get out of bed?
  1. The patient has a low blood sugar
  2. The patient is likely dehydrated
  3. The bacteria in the patient’s system are making her blood pressure fall
  4. She has a viral illness and will be fine
Explanation
Answer: B - The most likely reason for the patient to be having postural syncope (passing out when she stands) is due to a low blood pressure associated with dehydration. Elderly patients often have less of an ability to tolerate fluctuations in fluid status; thus, are more susceptible to symptoms associated with dehydration. Additionally, many elderly people are on blood pressure medications which further deteriorate the body’s ability to manage the loss of fluid.
