1. Risk factors that have been shown to contribute to age-related macular degeneration include _____.

• A. oxidative stress from sunlight
• B. iron-deficiency anemia
• C. decreased intake of phytochemicals
• D. vitamin B6 malabsorption

Correct answer: A

Rationale: The correct answer is A: oxidative stress from sunlight. Oxidative stress caused by exposure to sunlight is a significant risk factor for age-related macular degeneration. This condition can result in vision loss among older individuals. Choices B, C, and D are incorrect. Iron-deficiency anemia, decreased intake of phytochemicals, and vitamin B6 malabsorption are not established risk factors for age-related macular degeneration.

2. A nurse is providing discharge teaching about food choices to a client who has hypokalemia. Which of the following foods should the nurse identify as the best source of potassium?

• A. 1 cup grapes
• B. 1 cup shredded lettuce
• C. 1 cup cooked tomatoes
• D. 1 cup apple slices

Correct answer: C

Rationale: Cooked tomatoes are high in potassium, which is crucial for maintaining normal cell function, nerve transmission, and muscle contraction, making them a suitable choice for addressing hypokalemia. Grapes, shredded lettuce, and apple slices do not contain as much potassium as cooked tomatoes, so they are not the best choice for addressing hypokalemia.

3. he can be expected to:

• A. Profit from vocational training with moderate supervision
• B. Live successfully in the community
• C. Perform simple tasks in closely supervised settings
• D. Acquire academic skills of 6th grade level

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. Wernicke-Korsakoff syndrome is associated with which vitamin deficiency?

• A. Thiamine (B1)
• B. Riboflavin (B2)
• C. Niacin (B3)
• D. Pyridoxine (B6)

Correct answer: A

Rationale: Wernicke-Korsakoff syndrome is indeed associated with thiamine (vitamin B1) deficiency. This syndrome is commonly seen in individuals with chronic alcoholism due to poor diet and impaired thiamine absorption. Thiamine is essential for normal brain function and energy metabolism. Riboflavin (B2) deficiency can lead to symptoms like sore throat and swollen mucous membranes, not Wernicke-Korsakoff syndrome. Niacin (B3) deficiency causes pellagra, characterized by dermatitis, diarrhea, dementia, and death, but not Wernicke-Korsakoff syndrome. Pyridoxine (B6) deficiency can result in dermatitis, glossitis, and peripheral neuropathy, but it is not associated with Wernicke-Korsakoff syndrome.

5. What are the best food sources of magnesium?

• A. oils, bananas, and pork
• B. pizza, potatoes, and tomatoes
• C. milk, rice, and apples
• D. legumes, whole grains, and chocolate

Correct answer: D

Rationale: The correct answer is D: legumes, whole grains, and chocolate. These foods are rich sources of magnesium, an essential mineral that plays a role in over 300 biochemical reactions in the body. Choices A, B, and C do not contain as high levels of magnesium compared to legumes, whole grains, and chocolate.
