Multiple Choice Questions on Gastrointestinal Disorders Quizlet Questions
Question 1 of 5
In which region of the GI tract is the longitudinal muscle of the muscularis arranged into distinct longitudinal bundles?
Correct Answer: D
Rationale: The correct answer is D: Colon. The colon has the longitudinal muscle of the muscularis arranged into distinct longitudinal bundles called taeniae coli. This unique structure helps in the formation of haustra, the pouches seen in the colon. In contrast, the duodenum, jejunum, and ileum do not have this specific arrangement of longitudinal muscle bundles. The duodenum has a smooth muscle layer, while the jejunum and ileum have a continuous layer of smooth muscle without distinct longitudinal bundles. Therefore, the colon is the region of the GI tract where the longitudinal muscle is organized into distinct bundles.
Question 2 of 5
Which nursing action is appropriate when coaching obese adults enrolled in a behavior modification program?
Correct Answer: B
Rationale: The correct answer is B because asking about situations that tend to increase appetite helps identify triggers for overeating, aiding in behavior modification. This approach targets the root cause of overeating. A is incorrect as focusing solely on caloric intake may not address emotional or situational triggers for overeating. C is incorrect as suggesting rewards like sugarless candy may not address the underlying behaviors contributing to obesity. D is incorrect as eating small amounts frequently may not address the behavioral and psychological aspects of overeating.
Question 3 of 5
Which information will the nurse include when teaching a patient how to avoid chronic constipation? (Select all that apply.)
Correct Answer: B
Rationale: The correct answer is B: Bulk-forming laxatives are an excellent source of fiber. Fiber helps to soften stools, regulate bowel movements, and prevent constipation. By increasing fiber intake through bulk-forming laxatives or dietary sources, the patient can promote regularity and prevent chronic constipation. Explanation for incorrect choices: A: Stimulant and saline laxatives can cause dependency and are not recommended for regular use as they can disrupt the natural bowel function. C: While physical activity like walking or cycling can aid in bowel motility, it is not the primary factor in preventing chronic constipation. D: Timing of bowel movements can vary among individuals, and there is no specific "good time" universally applicable for everyone to have a bowel movement.
Question 4 of 5
The portion of a tooth which lies within the mandible socket is called the _____.
Correct Answer: C
Rationale: The correct answer is C: root. The root of a tooth is the portion that lies within the mandible socket, anchoring the tooth in place. The root helps support the tooth and allows for the transfer of nutrients. Dentin (A) is the hard tissue beneath the enamel, crown (B) is the visible part of the tooth above the gumline, and cementum (D) covers the root surface but is not the portion within the mandible socket.
Question 5 of 5
Ferritin is a globular protein that transports and stores ______ in the liver and blood.
Correct Answer: D
Rationale: The correct answer is D: iron. Ferritin is a protein that binds and stores iron in the liver and blood. It plays a crucial role in regulating iron levels in the body. Glycogen (A) is a storage form of glucose, not stored by ferritin. Lipids (B) are not stored by ferritin either. Vitamin B12 (C) is mainly stored in the liver bound to specific proteins, not ferritin. Iron is the correct answer as it aligns with the main function of ferritin in iron transport and storage.
