Gastrointestinal Nursing Questions Questions
Question 1 of 5
Which of the following is not a part of the small intestine?
Correct Answer: D
Rationale: The correct answer is D: Colon. The colon is not a part of the small intestine; it is part of the large intestine. The small intestine consists of three parts: the duodenum, jejunum, and ileum. The duodenum is the first segment of the small intestine, followed by the jejunum and then the ileum. The colon, also known as the large intestine, comes after the small intestine in the digestive system. Therefore, the colon is not a part of the small intestine, making choice D the correct answer.
Question 2 of 5
A 25-yr-old male patient calls the clinic reporting diarrhea for 24 hours. Which action should the nurse take first?
Correct Answer: D
Rationale: The correct answer is D because asking the patient to describe the stools and associated symptoms helps the nurse gather important information for assessment. Understanding the frequency, consistency, color, and presence of blood in the stools can help determine the severity and potential causes of diarrhea. This information guides the nurse in deciding the appropriate next steps for care. Option A is incorrect as testing should be based on assessment findings. Option C is premature without assessing the patient first. Option B lacks relevance to the assessment process.
Question 3 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 4 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 5 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.
