Multiple Choice Questions on Gastrointestinal Disorders Quizlet Questions
Question 1 of 5
Which of the following is not a part of the digestive system?
Correct Answer: D
Rationale: The correct answer is D: Lungs. The lungs are not a part of the digestive system. The digestive system is responsible for breaking down food into nutrients, absorbing those nutrients, and eliminating waste. The lungs are part of the respiratory system, responsible for gas exchange. Liver (A) and gallbladder (B) are both part of the digestive system, aiding in digestion and nutrient absorption. Absorption (C) is a process within the digestive system, not a separate entity. In summary, the lungs do not play a role in the digestion process, making them the correct answer choice.
Question 2 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 3 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 4 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.
Question 5 of 5
The _____ are vessels that project into the villi and absorb fatty substances.
Correct Answer: A
Rationale: The correct answer is A: lacteals. Lacteals are specialized lymphatic vessels located in the villi of the small intestine. They are responsible for absorbing dietary fats and fat-soluble vitamins. Lymphatics (choice B) are a broader term for lymphatic vessels and nodes. Veins (choice C) are blood vessels that carry deoxygenated blood back to the heart. Arteries (choice D) are blood vessels that carry oxygenated blood away from the heart. Therefore, only lacteals specifically project into the villi and absorb fatty substances, making them the correct choice.
