She complains of 4-5 loose, watery stools a day, bloating, and mild abdominal pain. She has a microcytic anemia, signs of fat and lean muscle wasting, and osteopenia. She is determined to have failed medical management and undergoes an ileocecectomy. Which of the following vitamins is she most likely to eventually need to take as a supplement?

Q

You perform a telephone evaluation of a patient who relates increased redness, pain, and swelling around his existing low-profile gastrostomy tube (G-tube). He has not been seen in the clinic for more than 6 months and, when asked, states that he has been doing quite well on his enteral tube feeds. In fact, the patient states that he has gained over 20 lbs. You would proceed as follows:

a. Congratulate him on gaining the weight and tell him to continue his present tube feeding plan
b. If possible, have him come to clinic or call the clinician managing the tube to rule out buried bumper syndrome
c. Direct him to put some triple antibiotic around the site and call back in a couple of weeks if the discomfort continues
d. Tell him to put hot packs on it, take acetaminophen, and rest for a few days

Q

An 18-year-old female patient with cystic fibrosis had a standard-profile, solid internal bolster, 20-French percutaneous endoscopic gastrostomy tube placed 1 year ago because of her inability to take in enough energy orally and weight loss. She has done very well, with her weight stabilizing and no complications of the PEG. The original tube is now getting stiff and cracking, and the patient wants a replacement tube. The patient has a very supportive family environment, is very active, and is concerned about the cosmetic appearance of the tube itself. What type of replacement tube would you recommend?
A .Standard-profile, 20-Fr percutaneous G-tube with solid internal bolster
B .Standard-profile, 20-Fr percutaneous G-tube with balloon internal bolster
