Questions on Gastrointestinal Tract Questions
Question 1 of 5
The buildup of bile pigment in tissues that can be caused by gallstones is _____.
Correct Answer: B
Rationale: The correct answer is B: obstructive jaundice. Gallstones can obstruct the bile duct, leading to the buildup of bile pigment in tissues, causing jaundice. This results in the characteristic yellowing of the skin and eyes. Hyperbilirubinemia (A) refers to elevated levels of bilirubin in the blood, which can occur in various liver conditions. Hepatitis (C) is inflammation of the liver, which can also lead to jaundice but is not directly caused by gallstones. Hepatocellular jaundice (D) is due to liver cell damage, not bile duct obstruction.
Question 2 of 5
Which of the following hydrolytic enzymes act in low pH?
Correct Answer: D
Rationale: The correct answer is D: Proteases. Proteases are enzymes that break down proteins, and they are known to function optimally in low pH environments, such as the acidic environment of the stomach. This is because the acidic pH helps in the activation and stability of proteases, allowing them to efficiently break down proteins into smaller peptides and amino acids. Rationale for why the other choices are incorrect: A: Peroxidases catalyze oxidation reactions and are not specifically known to act in low pH environments. B: Hydrolases are a broad category of enzymes that catalyze the hydrolysis of various molecules but are not specifically tailored for low pH conditions. C: Amylases are enzymes that break down carbohydrates and typically work best in neutral to slightly alkaline pH conditions, not in low pH environments like proteases.
Question 3 of 5
A nurse is teaching a client about strategies to manage gastroesophageal reflux disease (GERD). Which of the following statements should the nurse include?
Correct Answer: D
Rationale: The correct answer is D: Avoid eating 2 to 3 hours before bedtime. This is because lying down after eating can worsen GERD symptoms by allowing stomach acid to flow back up into the esophagus. By avoiding eating close to bedtime, the client can reduce the risk of acid reflux. A: Elevating the head of the bed helps reduce nighttime symptoms, but it is not the most essential strategy. B: Avoiding snacking between meals can help, but the timing of meals is more crucial for managing GERD. C: Limiting foods high in fiber is not directly related to managing GERD; it is more about avoiding trigger foods like citrus, caffeine, and fatty foods.
Question 4 of 5
You're performing an abdominal assessment on Brent who is 52 y.o. In which order do you proceed?
Correct Answer: A
Rationale: The correct order for an abdominal assessment is inspection, percussion, palpation, and auscultation (A). Inspection allows observation of any visible abnormalities. Percussion helps assess the density of underlying structures. Palpation is performed last to avoid altering bowel sounds before auscultation. Auscultation is done last to prevent altering bowel sounds while palpating. Choices B, C, and D are incorrect because they do not follow the proper sequence for an abdominal assessment, which can lead to inaccurate findings.
Question 5 of 5
The nervous system or systems that can control peristalsis in the inferior esophagus, stomach, small intestine and large intestine is (are) the
Correct Answer: C
Rationale: The correct answer is C because peristalsis, the involuntary movement of the digestive tract, is controlled by both sympathetic and parasympathetic nervous systems. The parasympathetic nervous system stimulates peristalsis, while the sympathetic nervous system inhibits it. Choice A is incorrect because the somatic motor nervous system controls voluntary movements, not peristalsis. Choice B is incorrect because the sympathetic nervous system inhibits peristalsis. Choice D is incorrect because the somatic motor nervous system does not control peristalsis in the digestive tract; it controls skeletal muscle movements.
