  • Which liver function contributes to the process of digestion?

  • Which digestive organ has a highly folded surface?
    The small intestine has a highly folded surface to increase surface area for absorption.

    Vitamin K production
  • What is an example of a monogastric animal?
    Human
  • What type of macromolecule does pepsin digest?
    Pepsin digests proteins.
  • What is the primary function of the large intestine?
    The primary function of the large intestine is water absorption and waste excretion.
  • What breaks up the fat in a fat-soluble vitamin in our bodies?
    Bile breaks up the fat in a fat-soluble vitamin to aid in its digestion and absorption.
  • Which organ is not an accessory organ of digestion?
    Esophagus
  • Which interventions would be recommended for a client with dysphagia? Select all that apply. a) Thickened liquids b) Pureed foods c) Carbonated beverages d) Large meals
    a) Thickened liquids, b) Pureed foods
  • What is ingestion in the context of digestion?
    Ingestion is the process of taking food and liquids into the mouth.
  • Which organ produces and secretes enzymes essential for proper digestion?
    Pancreas
  • What are the three phases of gastric secretion?
    The three phases of gastric secretion are the cephalic phase, gastric phase, and intestinal phase.
  • Which two organs help to break food down mechanically?
    The teeth and the stomach help to break food down mechanically.
  • What is chyme?
    Chyme is the partially digested food mixed with gastric juices found in the stomach and small intestine.
  • What is the most popular meal-planning approach used by diabetics?
    The carbohydrate counting method is the most popular meal-planning approach used by diabetics.
  • Which organ(s) works with the digestive system to regulate blood sugar levels?
    The pancreas works with the digestive system to regulate blood sugar levels by producing insulin and glucagon.
  • When caring for a client with acute pancreatitis, what is the most important nursing intervention?
    The most important nursing intervention is to ensure the client is NPO (nothing by mouth) to rest the pancreas.
  • As wastes navigate the large intestine, what is primarily absorbed?
    Water is primarily absorbed as wastes navigate the large intestine.
  • How is chyme different from a bolus?
    Chyme is partially digested food mixed with gastric juices in the stomach, while a bolus is chewed food mixed with saliva in the mouth and esophagus.
  • Which large blood vessel transports nutrients from the small intestine directly to the liver?
    The hepatic portal vein transports nutrients from the small intestine directly to the liver.
  • Nutrition support is needed if burns cover what proportion of total body surface area?
    Nutrition support is needed if burns cover more than 20% of the total body surface area.
  • Which organ is not an accessory organ of the digestive system?
    Stomach
  • What is the outermost layer of the digestive tract wall?
    The outermost layer of the digestive tract wall is the serosa.
  • What foods should not be eaten while on spironolactone?
    Foods high in potassium, such as bananas and oranges, should be avoided while on spironolactone.
  • Which of the enzymes produced in pancreatic juice breaks down carbohydrates into smaller components?
    Amylase is the enzyme in pancreatic juice that breaks down carbohydrates into smaller components.
  • Which of these is an organ that helps produce enzymes for the digestive process? a) Liver b) Stomach c) Pancreas d) Gallbladder
    c) Pancreas
  • What is the function of the cecum?
    The cecum is involved in the absorption of fluids and salts that remain after intestinal digestion and absorption.
  • A client vomits postoperatively. What is the most important nursing intervention?
    The most important nursing intervention is to ensure the client's airway is clear and to prevent aspiration.
  • What is the estimated average intake (EAR)?
    The Estimated Average Requirement (EAR) is the daily nutrient intake level estimated to meet the requirements of half the healthy individuals in a particular life stage and gender group.
  • What statement does not pertain to the cephalic phase of gastric secretion?
    The cephalic phase does not involve the direct presence of food in the stomach; it is triggered by the sight, smell, or thought of food.
  • The teeth and tongue contribute to which function of the digestive system?
    The teeth and tongue contribute to mechanical digestion by chewing and manipulating food.
  • What is the role of the gut microbiome in human digestion?
    The gut microbiome aids in the digestion of certain carbohydrates, synthesizes vitamins, and protects against harmful bacteria.
  • What is the inactive precursor of pepsin?
    The inactive precursor of pepsin is pepsinogen.
  • What is the function of the enzymes secreted from the small intestine and the pancreas?
