BAH Study Questions Test 6 Ch 44, 45, 46, 47, 48 Chapter 44 1. A nurse is caring for a patient who is scheduled for a colonoscopy and whose bowel preparation will include polyethylene glycol electrolyte lavage prior to the procedure. The presence of what health problem would contraindicate the use of this form of bowel preparation? A) Inflammatory bowel disease B) Intestinal polyps C) Diverticulitis D) Colon cancer Ans: A Feedback: The use of a lavage solution is contraindicated in patients with intestinal obstruction or inflammatory bowel disease. It can safely be used with patients who have polyps, colon cancer, or diverticulitis. 2. A nurse is promoting increased protein intake to enhance a patients wound healing. The nurse knows that enzymes are essential in the digestion of nutrients such as protein. What is the enzyme that initiates the digestion of protein? A) Pepsin B) Intrinsic factor C) Lipase D) Amylase Ans: A Feedback: The enzyme that initiates the digestion of protein is pepsin. Intrinsic factor combines with vitamin B12 for absorption by the ileum. Lipase aids in the digestion of fats and amylase aids in the digestion of starch. 3. A patient has been brought to the emergency department with abdominal pain and is subsequently diagnosed with appendicitis. The patient is scheduled for an appendectomy but questions the nurse about how his health will be affected by the absence of an appendix. How should the nurse best respond?

A) Your appendix doesnt play a major role, so you wont notice any difference after you recovery from surgery. B) The surgeon will encourage you to limit your fat intake for a few weeks after the surgery, but your body will then begin to compensate. C) Your body will absorb slightly fewer nutrients from the food you eat, but you wont be aware of this. D) Your large intestine will adapt over time to the absence of your appendix. Ans: A Feedback: The appendix is an appendage of the cecum (not the large intestine) that has little or no physiologic function. Its absence does not affect digestion or absorption. 4. A patient asks the nursing assistant for a bedpan. When the patient is finished, the nursing assistant notifies the nurse that the patient has bright red streaking of blood in the stool. What is this most likely a result of? A) Diet high in red meat B) Upper GI bleed C) Hemorrhoids D) Use of iron supplements Ans: C Feedback: Lower rectal or anal bleeding is suspected if there is streaking of blood on the surface of the stool. Hemorrhoids are often a cause of anal bleeding since they occur in the rectum. Blood from an upper GI bleed would be dark rather than frank. Iron supplements make the stool dark, but not bloody and red meat consumption would not cause frank blood. 5. An adult patient is scheduled for an upper GI series that will use a barium swallow. What teaching should the nurse include when the patient has completed the test?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
