1. What is the function of villi and microvilli in the GI tract?

• A. produce bile
• B. kill bacteria
• C. produce vitamin K
• D. increase the surface area for absorption

Correct answer: D

Rationale: Villi and microvilli in the GI tract serve to increase the surface area of the small intestine, aiding in the absorption of nutrients into the bloodstream. Choices A, B, and C are incorrect as villi and microvilli are primarily involved in enhancing absorption, not in producing bile, killing bacteria, or producing vitamin K.

2. A client with chronic pancreatitis is receiving discharge teaching from a nurse. Which of the following statements should the nurse make?

• A. "You should decrease your caloric intake when experiencing abdominal pain."?
• B. "You should increase your daily intake of protein."?
• C. "You should increase fat intake when experiencing loose stools."?
• D. "You should limit alcohol intake to 2-3 drinks per week."?

Correct answer: B

Rationale: In chronic pancreatitis, it is important to increase protein intake to support healing and prevent malnutrition. Choice A is incorrect because decreasing caloric intake during abdominal pain may lead to further nutritional deficiencies. Choice C is incorrect as increasing fat intake can exacerbate symptoms due to the impaired fat digestion in chronic pancreatitis. Choice D is incorrect as alcohol should be completely avoided in chronic pancreatitis to prevent further damage to the pancreas.

3. In any event of an adverse hemolytic reaction during blood transfusion, Nursing intervention should focus on:

• A. Slow the infusion, Call the physician and assess the patient
• B. Stop the infusion, Assess the client, Send the remaining blood to the laboratory and call the physician
• C. Stop the infusion, Call the physician and assess the client
• D. Slow the confusion and keep a patent IV line open for administration of medication

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

4. _____ neutralizes stomach acid in the small intestine:

• A. saliva
• B. gastric mucus
• C. bicarbonate ions
• D. enzymes

Correct answer: C

Rationale: The correct answer is C: bicarbonate ions. Bicarbonate ions, secreted by the pancreas, neutralize the acidic chyme entering the small intestine from the stomach, creating a more suitable environment for digestive enzymes. Saliva (choice A) helps in the initial breakdown of food in the mouth, not in neutralizing stomach acid. Gastric mucus (choice B) protects the stomach lining from the acidic environment but does not neutralize the acid in the small intestine. Enzymes (choice D) facilitate chemical reactions in digestion but do not neutralize stomach acid.

5. Which enzyme is most essential for the digestion of triglycerides found in butterfat?

• A. Gastric lipase
• B. Pepsin
• C. Mucus
• D. Intrinsic factor

Correct answer: A

Rationale: The correct answer is A: Gastric lipase. Gastric lipase is crucial for the digestion of short- and medium-chain triglycerides, such as those found in butterfat. Pepsin is involved in protein digestion, not lipid digestion. Mucus acts as a protective barrier in the stomach and does not play a direct role in lipid digestion. Intrinsic factor is involved in the absorption of vitamin B12 and is not related to the digestion of triglycerides.
