1. Which enzyme digests fiber in the large intestine?

• A. salivary amylase
• B. pancreatic amylase
• C. cellulase
• D. none of the above

Correct answer: D

Rationale: The correct answer is 'none of the above.' Human digestive enzymes like salivary amylase and pancreatic amylase cannot digest fiber. Instead, fiber is fermented by gut bacteria in the large intestine. Cellulase, which is an enzyme produced by some animals and microorganisms, can break down cellulose found in plants, but it is not a human digestive enzyme, making it an incorrect choice in this context.

2. _____ neutralizes stomach acid in the small intestine:

• A. saliva
• B. gastric mucus
• C. bicarbonate ions
• D. enzymes

Correct answer: C

Rationale: The correct answer is C: bicarbonate ions. Bicarbonate ions, secreted by the pancreas, neutralize the acidic chyme entering the small intestine from the stomach, creating a more suitable environment for digestive enzymes. Saliva (choice A) helps in the initial breakdown of food in the mouth, not in neutralizing stomach acid. Gastric mucus (choice B) protects the stomach lining from the acidic environment but does not neutralize the acid in the small intestine. Enzymes (choice D) facilitate chemical reactions in digestion but do not neutralize stomach acid.

3. One of the following statements is true with regards to the care of clients with depression:

• A. Only mentally ill persons commit suicide
• B. All depressed clients are considered potentially suicidal
• C. Most suicidal person gives no warning
• D. The chance of suicide lessens as depression lessens

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

4. Which of the following is not correct?

• A. energy density is a comparison of energy (kcals) content to the weight of food
• B. if a food product contains a 15% daily value of calcium, that product is said to be a low source of calcium
• C. MyPlate illustrates the 5 food groups
• D.

Correct answer: B

Rationale: A product with 15% Daily Value (DV) of calcium is considered a good source, not a low source. Typically, anything 10-19% DV is considered a good source.

5. During which phase of the therapeutic relationship should the nurse inform the patient about the termination of therapy?

• A. Pre-orientation
• B. Orientation
• C. Working
• D. Termination

Correct answer: D

Rationale: The correct answer is 'Termination'. This phase of the therapeutic relationship is when the nurse informs the patient about the conclusion of therapy. It is during this phase that the nurse and the patient review the goals and progress made and also discuss the upcoming termination. The other phases are not the appropriate times for discussing termination. 'Pre-orientation' is the phase before the nurse-patient relationship is established; 'Orientation' is when the nurse and patient get to know each other and set goals; and 'Working' is when these goals are pursued. Therefore, choices A, B, and C are incorrect.
