1. Glucagon is a hormone released into the bloodstream in response to high blood sugar. It helps to lower blood glucose after a meal.

Correct answer: B

Rationale: Glucagon is released in response to low blood sugar and raises blood glucose levels by stimulating the release of glucose from liver stores, not lowering it.

2. Which enzyme is most essential for hydrolyzing large protein molecules?

Correct answer: B

Rationale: Pepsin, choice B, is the correct answer as it is a proteolytic enzyme that is essential for the breakdown of large protein molecules in the stomach. Gastric lipase, choice A, is incorrect because it primarily targets fats, not proteins, hence it is not involved in protein hydrolysis. Mucus, choice C, is incorrect as it serves to protect the stomach lining from acidic gastric juices and does not play a direct role in protein digestion. Intrinsic factor, choice D, is incorrect as it is vital for the absorption of Vitamin B12 in the small intestine and doesn't participate in the process of hydrolyzing proteins.

3. What describes a common physical change of aging that can affect an older adult's nutrition?

Correct answer: A

Rationale: Reduced salivary output is a common physical change in aging. This can affect an older adult's nutrition by impacting chewing, swallowing, and taste perception. The decrease in saliva production can make it harder to chew and swallow food effectively, affecting the overall eating experience. Additionally, saliva plays a role in taste perception, so a reduction in salivary output can lead to alterations in how food tastes, potentially impacting an individual's appetite and food choices. Increased gastrointestinal motility (choice B) is not typically associated with aging and would not directly affect nutrition. Abnormal cortisol production (choice C) is related to hormonal changes and is not a common physical change of aging that affects nutrition. An increase in the number of taste buds (choice D) is not a typical change associated with aging and would not have a significant impact on an older adult's nutrition.

4. A client at risk for iron-deficiency anemia is being taught by a nurse about optimizing dietary intake of iron. The nurse should explain that which of the following sources of iron is easiest for the body to absorb?

Correct answer: C

Rationale: The correct answer is 'Chicken.' Chicken contains heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based sources like spinach, cantaloupe, and lentils. Heme iron, as present in chicken, is more bioavailable and is better absorbed by the body, making it an excellent source of iron for individuals at risk of iron-deficiency anemia. Spinach, cantaloupe, and lentils contain non-heme iron, which is not as efficiently absorbed as heme iron.

5. Data analysis is to be done and the nurse researcher wants to include variability. These include the following EXCEPT:

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
