Which of these statements about bile is true?
- A. About 500 mL is secreted daily.
- B. Its main function is the denaturation of proteins.
- C. It is synthesized in the gallbladder.
- D. Bile salts are recycled.
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.

A young adult patient is admitted to the hospital for evaluation of right lower quadrant abdominal pain with nausea and vomiting. Which action should the nurse take?
- A. Assist the patient to cough and deep breath
- C. Palpate the abdomen for rebound tenderness.
- D. Suggest the patient lie on the side, flexing the right leg.
Correct Answer: C
Rationale: The correct answer is C: Palpate the abdomen for rebound tenderness. This action is essential to assess for signs of possible appendicitis, a common cause of right lower quadrant abdominal pain with nausea and vomiting. Rebound tenderness is a classic sign of peritoneal irritation and can indicate an inflamed appendix. The other choices are incorrect because:
A: Assisting the patient to cough and deep breath is not a priority in this situation and does not provide relevant information about the cause of the abdominal pain.
D: Suggesting the patient lie on the side, flexing the right leg, may help alleviate some discomfort but does not provide diagnostic information about the underlying cause of the symptoms.
A client is visited by the dietitian following a colostomy procedure. Which of the following is the primary nutrition concern for this type of client?
- A. Fiber.
- B. Small frequent meals.
- C. Chewing food thoroughly.
- D. Fluids and electrolytes.
Correct Answer: D
Rationale: Maintaining fluid and electrolyte balance is crucial for colostomy clients, as water absorption is affected.
Na+ and other carrier ions facilitate absorption of
- A. amino acids and fructose
- B. fatty acids and glycerol
- C. fatty acids and glucose
- D. amino acids and glucose
Correct Answer: D
Rationale: Na+ facilitates the absorption of glucose and amino acids through sodium-dependent transporters in the intestinal cells. Glucose and amino acids are transported into the cells along with Na+ ions, making option D the correct choice. Choices A, B, and C are incorrect because Na+ does not facilitate the absorption of fructose, fatty acids, or glycerol through specific transport mechanisms.
A patient with advanced cirrhosis has a nursing diagnosis of imbalanced nutrition: less than body requirements related to anorexia and inadequate food intake. What would be an appropriate midday snack for the patient?
- A. Peanut butter and salt-free crackers
- B. A fresh tomato sandwich with salt-free butter
- C. Popcorn with salt-free butter and herbal seasoning
- D. Canned chicken noodle soup with low-protein bread
Correct Answer: A
Rationale: Peanut butter and salt-free crackers provide protein and energy, which can help address nutritional deficiencies in a patient with cirrhosis.
What is the function of bile in digestion?
- A. Emulsify fats
- B. Break down proteins
- C. Break down carbohydrates
- D. None of the above
Correct Answer: A
Rationale: The correct answer is A: Emulsify fats. Bile emulsifies fats by breaking them down into smaller droplets, increasing the surface area for enzymes to work on, aiding in the digestion and absorption of fats. Choices B and C are incorrect as bile specifically targets fats, not proteins or carbohydrates. Choice D is incorrect as bile plays a crucial role in fat digestion.
