Gastrointestinal Nursing Questions Questions
Question 1 of 5
Proteins are split by all of the following pancreatic factors except which one?
Correct Answer: A
Rationale: The correct answer is A: zymogen. Zymogen is an inactive precursor form of an enzyme that is converted to its active form by certain conditions, such as pH or other enzymes. In contrast, chymotrypsin, trypsin, and carboxypeptidase are all pancreatic enzymes directly involved in the breakdown of proteins. Therefore, zymogen does not directly split proteins, making it the exception among the pancreatic factors listed.
Question 2 of 5
Which of the following is a major site of nutrient absorption?
Correct Answer: B
Rationale: The correct answer is B: jejunum. The jejunum is a major site of nutrient absorption in the small intestine due to its extensive surface area and presence of villi and microvilli that facilitate absorption of nutrients like carbohydrates, proteins, and fats. The duodenum primarily functions in digestion, the ileum mainly absorbs vitamin B12 and bile salts, and the colon absorbs water and electrolytes. Therefore, the jejunum is the correct choice for being a major site of nutrient absorption.
Question 3 of 5
A nurse is providing instructions for a 52-year-old client who is scheduled for a colonoscopy. The client reports that he has not had the procedure before and is very anxious about feeling pain during the procedure. Which of the following responses by the nurse is appropriate?
Correct Answer: B
Rationale: Step 1: Providing a sedative before the colonoscopy is appropriate as it helps reduce anxiety and discomfort during the procedure. Step 2: Sedatives induce relaxation and drowsiness, making the client feel sleepy and less likely to experience pain. Step 3: Addressing the client's anxiety by mentioning the sedative shows empathy and reassurance. Step 4: This option focuses on addressing the client's concern about pain during the procedure effectively. Summary: - Option A dismisses the client's concerns and does not provide a solution. - Option C acknowledges the anxiety but does not offer a specific solution. - Option D delays addressing the client's anxiety without providing immediate reassurance or information.
Question 4 of 5
A nurse is instructing a client who has GERD about positions that can help minimize the effects of reflux during sleep. Which of the following statements indicates to the nurse that the client understands the instructions?
Correct Answer: A
Rationale: The correct answer is A: "I will lie on my left side to sleep at night." This position helps prevent acid from flowing back into the esophagus due to the angle of the stomach in relation to the esophagus. Lying on the right side can worsen reflux. Sleeping on the back with the head flat can also worsen symptoms as gravity can allow acid to flow back up. Sleeping on the stomach with the head flat is not recommended as it can put pressure on the stomach, leading to increased reflux.
Question 5 of 5
A male client with a recent history of rectal bleeding is being prepared for a colonoscopy. How should the nurse position the client for this test initially?
Correct Answer: B
Rationale: The correct answer is B: Lying on the left side with knees bent. This position allows for better visualization and access to the colon during the colonoscopy procedure. By lying on the left side, the client's colon is in a more optimal position for the scope to navigate through the colon. Additionally, bending the knees helps to relax the abdominal muscles and make the procedure more comfortable for the client. Incorrect choices: A: Lying on the right side with legs straight - This position does not provide optimal access to the colon and may make the procedure more difficult. C: Prone with the torso elevated - This position is not suitable for a colonoscopy as it does not allow for proper access to the colon. D: Bent over with hands touching the floor - This position is not recommended for a colonoscopy as it is not conducive to the procedure and may cause discomfort for the client.
