    If the gastric residual exceeds 100 cc 2 hours in a row, the physician should be notified.
  2. notify the physician.
    One observation of a residual gastric content over 100 cc does not have to be reported to the physician. If the observation occurs two times in succession, the physician should be notified.
  3. give the tube feeding.
    If the amount of gastric residual exceeds 100 cc, the tube feeding should be withheld at that time.
  4. withhold the tube feeding indefinitely.
    If the amount of gastric residual exceeds 100 cc, the tube feeding should be withheld at that time, but not indefinitely.

47. If tube feeding is continuous, the placement of the feeding tube should be checked

  1. every shift.
    Each nurse caring for the patient is responsible for verifying that the tube is located in the proper area for continuous feeding.
  2. every hour.
    Checking for placement each hour is unnecessary unless the patient is extremely restless or there is basis for rechecking the tube based on other patient activities.
  3. every 24 hours.
    Checking for placement every 24 hours does not meet the standard of care due the patient receiving continuous tube feedings.
  4. when a tube feeding is continuous, it is unnecessary to check placement.
    Even though the feedings are continuous, the placement must be assessed.

48. Decrease in absorption of which of the following vitamins in the geriatric patient results in pernicious anemia?

    Vitamin B12 requires the intrinsic factor secreted by the gastric mucosa for absorption.
  2. C
