Once absorbed into the epithelial cell of the small intestine, free fatty acids and glycerol are recombined and a protein coat is added to form a

  • A. chylomicron.
  • B. micelle.
  • C. lipoprotein.
  • D. fatty droplet.
Correct Answer: A

Rationale: The correct answer is A: chylomicron. After absorption, free fatty acids and glycerol are recombined in the epithelial cell to form triglycerides. These triglycerides are then packaged with proteins to form chylomicrons, which are lipoprotein particles that transport dietary fats through the lymphatic system and bloodstream. Chylomicrons are essential for the absorption of dietary fats and fat-soluble vitamins.

Summary:
- B: Micelle is incorrect because micelles are formed in the lumen of the small intestine to aid in the absorption of lipids but do not involve recombination of fatty acids and glycerol.
- C: Lipoprotein is incorrect because while chylomicrons are a type of lipoprotein, the specific process described in the question is not about general lipoprotein formation.
- D: Fatty droplet is incorrect as it does not involve the recombination and protein coating process described in the question.

Diseases that reduce pancreatic enzyme secretions do NOT usually decrease the digestion and absorption of:

  • A. Animal proteins
  • B. Plant proteins
  • C. Plant lipids
  • D. Sucrose
Correct Answer: D

Rationale: The correct answer is D: Sucrose. Diseases that reduce pancreatic enzyme secretions typically do not affect the digestion and absorption of sucrose because sucrose is primarily broken down in the small intestine by sucrase, an enzyme produced by the intestinal lining, not the pancreas. Animal proteins (choice A) and plant proteins (choice B) require pancreatic enzymes like trypsin and chymotrypsin for digestion; plant lipids (choice C) require pancreatic lipase for digestion. Therefore, choices A, B, and C would be affected by reduced pancreatic enzyme secretions, unlike sucrose.

The nurse needs to administer feedings to a client who has diarrhea due to gastroenteritis. Which of the following factors should the nurse consider?

  • A. Administer feedings at room temperature
  • B. Administer cold feedings
  • C. Administer bolus feedings
  • D. Administer intermittent feedings
Correct Answer: A

Rationale: Room temperature feedings reduce gastric irritation, which can help prevent worsening diarrhea.

A nurse is teaching a client how to do fecal occult blood testing. Which of the following statements by the client indicates a need for further teaching?

  • A. I will continue my low-dose aspirin therapy regimen.'
  • B. I will refrain from eating raw fruits and vegetables.'
  • C. I will avoid steak and other red meats.'
  • D. I will continue taking my Coumadin as prescribed.'
Correct Answer: A

Rationale: Rationale:
A: Low-dose aspirin can cause false positive results in fecal occult blood testing due to its effect on gastrointestinal bleeding. Therefore, the client should inform the healthcare provider and consider stopping or adjusting the aspirin therapy during the testing period.
B: Refraining from raw fruits and vegetables is correct as they can interfere with the test results.
C: Avoiding red meats is correct as they can also affect the test results.
D: Continuing Coumadin as prescribed is correct as it does not interfere with fecal occult blood testing.

What is the patient with chronic pancreatitis more likely to have than the patient with acute pancreatitis?

  • A. The need to abstain from alcohol
  • B. Experience acute abdominal pain
  • C. Malabsorption and diabetes mellitus
  • D. Require a high-carbohydrate, high-protein, low-fat diet
Correct Answer: C

Rationale: Chronic pancreatitis often leads to malabsorption and diabetes mellitus due to long-term pancreatic dysfunction.

The hormone which causes the pancreas to secrete an enzyme-rich fluid is _____.

  • A. cholecystokinin
  • B. secretin
  • C. enterogastrone
  • D. enterocrinin
Correct Answer: A

Rationale: The correct answer is A: cholecystokinin. Cholecystokinin stimulates the pancreas to secrete an enzyme-rich fluid to aid in digestion in response to the presence of fats and proteins in the small intestine. Secretin mainly stimulates bicarbonate secretion from the pancreas. Enterogastrone inhibits gastric emptying. Enterocrinin stimulates the secretion of digestive enzymes from the pancreas and also helps regulate the movements of the intestine.
