Gastrointestinal System Nursing Exam Questions Questions
Question 1 of 5
The nurse is obtaining a history of a patient with hepatitis Which question is most appropriate for the nurse to ask?
Correct Answer: D
Rationale: The correct answer is D because hepatitis can be transmitted through contaminated food or water, including shellfish. Asking about shellfish consumption helps assess the risk of exposure to hepatitis. Choice A is more relevant for HIV transmission. Choice B focuses on STDs. Choice C is not directly related to hepatitis transmission.
Question 2 of 5
The nurse is caring for a patient receiving chemotherapy. Which of the following signs indicates that the patient is developing a complication from the chemotherapy?
Correct Answer: B
Rationale: The correct answer is B: White blood cell count of 3,000 cells/mm3. A low white blood cell count is a common side effect of chemotherapy, putting the patient at risk for infections. Monitoring WBC count is crucial to detect complications early. A: Mild nausea is a common side effect of chemotherapy but does not necessarily indicate a complication. C: Reddened areas on the skin could be due to various reasons and are not specific to chemotherapy complications. D: Small amount of urine output could be a concern, but it is not a common sign of chemotherapy complications.
Question 3 of 5
Which of these statements about bile is true?
Correct Answer: D
Rationale: Step 1: Bile is produced in the liver, not the gallbladder. Step 2: Bile salts aid in digestion by emulsifying fats. Step 3: Bile salts are recycled in the enterohepatic circulation. Step 4: This recycling process conserves bile salts. Step 5: Choice D is correct as it accurately states that bile salts are recycled, supporting efficient digestion and absorption.
Question 4 of 5
Where does the absorption of most nutrients take place?
Correct Answer: B
Rationale: The correct answer is B: small intestine. The absorption of most nutrients occurs in the small intestine due to its large surface area, which is facilitated by villi and microvilli. Digestive enzymes and bile produced by the liver and pancreas help break down food into absorbable nutrients. Nutrients like carbohydrates, proteins, fats, vitamins, and minerals are absorbed through the walls of the small intestine and into the bloodstream for distribution to the body. The stomach primarily functions in digestion, while the large intestine absorbs water and salts and the rectum stores waste before elimination.
Question 5 of 5
Where are most digestive enzymes activated?
Correct Answer: B
Rationale: The correct answer is B: small intestine. Digestive enzymes are activated in the small intestine to break down nutrients. Firstly, enzymes are secreted by the pancreas into the small intestine, where they act on carbohydrates, proteins, and fats. Secondly, bile from the liver helps in the digestion of fats. The stomach mainly secretes gastric juices for protein digestion, not enzymes for overall digestion. The liver produces bile, not digestive enzymes. The pancreas secretes various digestive enzymes, but they become activated in the small intestine.
