Which two regions of a tooth contain living cells?

  • A. dentin and enamel
  • B. anatomical crown and cementum
  • C. enamel and cementum
  • D. dentin and cementum
Correct Answer: D

Rationale: The correct answer is D. Dentin and cementum are the two regions of a tooth that contain living cells. Dentin is the hard tissue beneath the enamel and cementum that forms the bulk of the tooth structure. It contains living cells called odontoblasts responsible for dentin formation. Cementum is the hard tissue covering the tooth root and is essential for anchoring the tooth in the jawbone. Cementum contains living cells called cementoblasts responsible for cementum formation. Therefore, both dentin and cementum are vital regions of a tooth that house living cells involved in tooth development and maintenance.

A: Dentin and enamel - Enamel is the outermost layer of the tooth and does not contain living cells.
B: Anatomical crown and cementum - Anatomical crown is not a region of the tooth containing living cells.
C: Enamel and cementum - Enamel does not contain living cells, only mineralized structures.

Which of these organs is not considered an accessory digestive structure?

  • A. mouth
  • B. salivary glands
  • C. pancreas
  • D. liver
Correct Answer: A

Rationale: The correct answer is A: mouth. The mouth is not considered an accessory digestive structure because it is part of the main digestive system. The mouth is where the process of digestion begins with the mechanical breakdown of food through chewing and the chemical breakdown through the action of saliva produced by salivary glands. The salivary glands, pancreas, and liver are all accessory digestive structures because they aid in the digestion process but are not part of the alimentary canal. Salivary glands produce enzymes to further break down food, the pancreas secretes digestive enzymes and bicarbonate into the small intestine, and the liver produces bile to aid in the digestion and absorption of fats. These organs work alongside the main digestive system to help with the breakdown and absorption of nutrients.

Which of the following enzymes is involved in the breakdown of proteins?

  • A. amylase
  • B. lipase
  • C. pepsin
  • D. maltase
Correct Answer: C

Rationale: The correct answer is C: pepsin. Pepsin is an enzyme produced in the stomach that helps break down proteins into peptides. It works in a highly acidic environment, denaturing proteins. Amylase (A) breaks down carbohydrates, lipase (B) breaks down fats, and maltase (D) breaks down maltose into glucose. Pepsin is specifically designed to target proteins, making it the correct choice.

Which nursing action is appropriate when coaching obese adults enrolled in a behavior modification program?

  • A. Having the adults write down the caloric intake of each meal
  • B. Asking the adults about situations that tend to increase appetite
  • C. Suggesting that the adults plan rewards, such as sugarless candy, for achieving their goals
  • D. Encouraging the adults to eat small amounts frequently rather than having scheduled meals Name: ID: A
Correct Answer: B

Rationale: The correct answer is B because asking about situations that tend to increase appetite helps identify triggers for overeating, aiding in behavior modification. This approach targets the root cause of overeating.
A is incorrect as focusing solely on caloric intake may not address emotional or situational triggers for overeating.
C is incorrect as suggesting rewards like sugarless candy may not address the underlying behaviors contributing to obesity.
D is incorrect as eating small amounts frequently may not address the behavioral and psychological aspects of overeating.

A nurse is caring for a client who has peptic ulcer disease. The nurse should monitor the client for which of the following findings as an indication of gastrointestinal perforation?

  • A. Hyperactive bowel sounds
  • B. Sudden abdominal pain
  • C. Increased blood pressure
  • D. Bradycardia
Correct Answer: B

Rationale: The correct answer is B: Sudden abdominal pain. Gastrointestinal perforation is a serious complication of peptic ulcer disease. Sudden abdominal pain is a key indicator as perforation can lead to leakage of stomach contents into the abdominal cavity causing severe pain. Hyperactive bowel sounds (A) are more indicative of bowel obstruction. Increased blood pressure (C) can occur due to pain or stress but is not specific to gastrointestinal perforation. Bradycardia (D) is not typically associated with gastrointestinal perforation.

Which of the following is true about the liver?

  • A. It produces digestive enzymes.
  • B. It stores bile.
  • C. It detoxifies drugs and alcohol.
  • D. It produces insulin.
Correct Answer: C

Rationale: The correct answer is C: The liver detoxifies drugs and alcohol. The liver contains enzymes that break down harmful substances, helping to remove toxins from the body. This process is essential for maintaining overall health.

Choice A is incorrect because the pancreas, not the liver, produces digestive enzymes. Choice B is also incorrect because the gallbladder, not the liver, stores bile. Choice D is incorrect because the pancreas, not the liver, produces insulin to regulate blood sugar levels.
