The portion of a tooth which lies within the mandible socket is called the _____.
- A. dentin
- B. crown
- C. root
- D. cementum
Correct Answer: C
Rationale: The correct answer is C: root. The root of a tooth is the portion that lies within the mandible socket, anchoring the tooth in place. The root helps support the tooth and allows for the transfer of nutrients. Dentin (A) is the hard tissue beneath the enamel, crown (B) is the visible part of the tooth above the gumline, and cementum (D) covers the root surface but is not the portion within the mandible socket.

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.
Cholesterol that is required to produce steroids and bile salts is carried in
- A. micelles.
- B. chylomicrons.
- C. low-density lipoproteins (LDL).
- D. high-density lipoproteins (HDL).
Correct Answer: C
Rationale: The correct answer is C: low-density lipoproteins (LDL). LDL carries cholesterol to tissues where it is needed for steroid synthesis and bile salt production. LDL is known as the "bad" cholesterol transporter because high levels can lead to plaque buildup in arteries. Micelles (A) are small lipid droplets in the intestine, chylomicrons (B) transport dietary fats, and HDL (D) is known as the "good" cholesterol transporter that helps remove excess cholesterol from the bloodstream.

Where does most nutrient absorption occur?
- A. Stomach
- B. Small intestine
- C. Large intestine
- D. Mouth
Correct Answer: B
Rationale: The correct answer is B: Small intestine. The small intestine is where most nutrient absorption occurs due to its large surface area, specialized villi, and microvilli that increase absorption efficiency. Digestive enzymes and bile are also secreted here to further break down nutrients. Stomach (A) primarily aids in digestion, not absorption. Large intestine (C) mainly absorbs water and electrolytes, not nutrients. Mouth (D) begins the digestion process by mechanical breakdown and some enzyme release, but minimal absorption occurs here.
