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. What is considered fast breathing in a 13-month-old child if the respiratory rate (RR) exceeds which value?

• A. 40 breaths per minute
• B. 50 breaths per minute
• C. 60 breaths per minute
• D. 30 breaths per minute

Correct answer: C

Rationale: In the context of pediatric care, a respiratory rate of more than 60 breaths per minute in a child aged 13 months is considered fast breathing, hence option 'C' is correct. Options 'A', 'B', and 'D' are incorrect as they do not meet the specified criteria for fast breathing in a 13-month-old. Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, including monitoring respiratory rates, to ensure that interventions are appropriately targeted and outcomes are optimized.

3. A nurse is teaching a client who needs to increase their daily fluid intake. Which of the following foods has the highest percentage of water by weight?

• A. Yogurt
• B. Milk
• C. Lettuce
• D. Honey

Correct answer: C

Rationale: The correct answer is Lettuce. Lettuce has the highest percentage of water by weight among the options provided, making it an excellent choice to increase fluid intake. Yogurt and milk have some water content but are not as high in water percentage as lettuce. Honey, on the other hand, contains very little water and is not a good choice for increasing fluid intake.

4. Following bariatric surgery, a patient would initially be given what type of diet?

• A. regular diet
• B. pureed diet
• C. clear liquid diet
• D. soft diet

Correct answer: C

Rationale: A clear liquid diet is typically the first step after bariatric surgery to allow the stomach to heal and prevent complications.

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

• A. Gastric lipase
• B. Pepsin
• C. Mucus
• D. Intrinsic factor

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.
