Gastrointestinal Nursing Questions Questions
Question 1 of 5
Bile facilitates digestion by causing the _____ of fats.
Correct Answer: D
Rationale: Bile facilitates digestion by emulsifying fats, breaking them down into smaller droplets for better absorption. Emulsification increases the surface area of fats for enzymes to work on. Hydrolysis (A) is the breakdown of molecules by adding water, not specific to fats. Digestion (B) is a general term encompassing all processes, not specific to fats. Catalysis (C) refers to the process of speeding up chemical reactions but doesn't specifically relate to fats like emulsification does.
Question 2 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 3 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 4 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.
Question 5 of 5
The stomach, small intestine and large intestine are lined by this epithelium.
Correct Answer: C
Rationale: The correct answer is C: simple columnar epithelium. This type of epithelium is found in the stomach, small intestine, and large intestine. Simple columnar epithelium is ideal for absorption and secretion due to its tall, column-like shape and presence of microvilli. It provides a large surface area for nutrient absorption. Simple squamous epithelium (choice A) is thin and is found in areas where filtration or diffusion occurs, like the lungs. Stratified squamous epithelium (choice B) is found in areas subject to mechanical stress, such as the skin. Pseudostratified columnar epithelium (choice D) is typically found in the respiratory tract and has cilia for moving mucus.
