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

• A. TRUE
• B. FALSE
• C.
• D.

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. The recommended treatment modality in clients with obsessive-compulsive disorder is:

• A. Psychotherapy
• B. Behavior therapy
• C. Aversion therapy
• D. Psychoanalysis

Correct answer: B

Rationale: The recommended treatment modality for clients with obsessive-compulsive disorder is Behavior Therapy, not Psychoanalysis. Behavior therapy, specifically exposure and response prevention, is considered the first-line treatment for OCD. This therapy focuses on changing the patterns of behavior that contribute to the disorder. Psychotherapy, although beneficial in some cases, is not as effective as behavior therapy for OCD. Aversion therapy involves associating a stimulus with a negative outcome to reduce the frequency of a specific behavior, which is not the primary approach for OCD.

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

• A. reduced salivary output
• B. increased gastrointestinal motility
• C. abnormal cortisol production
• D. increase in number of taste buds

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. Inadequate intake of vitamin A occurs in lower socioeconomic groups due to a lack of resources to purchase and consume vegetables and fruits.

• A. Both the statement and the reason are correct and related.
• B. Both the statement and the reason are correct but are not related.
• C. The statement is correct, but the reason is not correct.
• D. The statement is not correct, but the reason is correct.

Correct answer: A

Rationale: Both the statement and the reason are correct and related. Inadequate intake of vitamin A in lower socioeconomic groups is due to a lack of resources to purchase and consume vegetables and fruits. This is supported by the fact that the average intake in the United States meets the Recommended Dietary Allowance (RDA) for vitamin A intake, except in lower socioeconomic groups. These individuals often lack the financial means to buy, prepare, and eat a variety of fruits and vegetables, leading to deficiencies. It's important to note that because vitamin A can be stored in the liver, most adults have sufficient quantities to maintain health. Choices B, C, and D are incorrect because the statement and reason are both accurate and logically connected, as the lack of resources directly impacts the ability to obtain necessary sources of vitamin A.

5. Which of the following proteins is iron a component of, responsible for the transport of oxygen in the bloodstream?

• A. hemoglobin
• B. transferrin
• C. myoglobin
• D. hepcidin

Correct answer: A

Rationale: The correct answer is A: hemoglobin. Hemoglobin is the protein found in red blood cells that is responsible for carrying oxygen from the lungs to the rest of the body. Iron is a crucial component of hemoglobin, binding to oxygen and allowing for its transport. Choice B, transferrin, is involved in iron transport in the blood but not in oxygen transport. Choice C, myoglobin, is a protein found in muscle cells that stores oxygen for muscle use, not transportation in the bloodstream. Choice D, hepcidin, is a peptide hormone that regulates iron absorption in the intestines and iron distribution in the body, but it is not directly involved in oxygen transport.
