Gastrointestinal Nursing Questions Questions
Question 1 of 5
The _____ nervous system division usually stimulates and promotes digestion.
Correct Answer: D
Rationale: The correct answer is D: parasympathetic. The parasympathetic nervous system is responsible for rest and digest functions, including stimulating digestion. It slows heart rate, increases intestinal activity, and promotes the secretion of digestive enzymes. The somatic nervous system (A) controls voluntary movements, the sympathetic nervous system (B) is responsible for the fight or flight response, and the central nervous system (C) consists of the brain and spinal cord, serving as the main control center of the body.
Question 2 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 3 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 4 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 5 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.
