    • ANS: C
    • The glucose level is elevated. It is important to monitor glucose levels as ordered and to look for signs of hyperglycemia due to the high dextrose in PN. A. B. D. This data is all within normal limits.

23. The nurse is assisting with the care of a patient who has PN containing dextrose 50% infusing. The patient asks why the rate keeps being increased. How should the nurse respond to this patient?

    a.

    c.

    Allow the patient to take small sips of water.

    d.

    Inform the patient she must remain NPO (nothing by mouth) until she has bowel sounds.

    ANS:     C

    Because there is an order for liquids and the patient is stable, the nurse can provide the patient with sips of fluid. A. RN does not need to be informed prior to giving the fluids. B. D. There does not appear to be an advantage to maintaining patients NPO postoperatively until bowel function returns. If ordered, nutrition can be provided to patients undergoing GI surgery early postoperatively which may improve their recovery with fewer complications.

    The sense of taste becomes less acute, and there is greater likelihood of periodontal disease and oral cancer. There may be difficulties with chewing if teeth have been lost. Secretions throughout the GI tract are reduced, and the effectiveness of peristalsis diminishes because of loss of muscle elasticity and slowed motility. Indigestion may become more common, especially if the lower esophageal sphincter (LES) loses its tone, and there is greater chance of peptic ulcer. In the colon, diverticula may form.
