1. Causes of acute renal failure include:

• A. chronic renal failure
• B. uncontrolled diabetes mellitus
• C. recurrent urinary tract infections
• D. severe injury such as extensive burns

Correct answer: D

Rationale: The correct answer is D. Severe injuries, like extensive burns, can cause acute renal failure due to shock, reduced blood flow to the kidneys, and tissue damage. Choices A, B, and C are incorrect because chronic renal failure, uncontrolled diabetes mellitus, and recurrent urinary tract infections are more likely to contribute to chronic kidney disease rather than acute renal failure.

2. Because of increasing cases of fluorosis, low levels of fluoride are added to commercial infant formula. Breast milk provides low levels of fluoride.

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: D

Rationale: The first statement is false; fluoride is not added to infant formulas due to the risk of fluorosis. The second statement is true; breast milk contains low levels of fluoride.

3. Which biomolecule is responsible for the storage and transfer of genetic information?

• A. Carbohydrates
• B. Proteins
• C. Lipids
• D. Nucleic acids

Correct answer: D

Rationale: Nucleic acids, such as DNA and RNA, are the biomolecules responsible for storing and transferring genetic information within cells. Carbohydrates, proteins, and lipids do not have this specific function. Carbohydrates are mainly used for energy storage, structural support, and cellular communication. Proteins are involved in various cellular functions such as enzymatic reactions, structural support, and signaling. Lipids play roles in energy storage, cell membrane structure, and signaling.

4. A client needs to increase his protein intake and enjoys certain foods. Which of the following foods should the nurse recommend as the best source of protein among these suggestions?

• A. Yams
• B. Eggs
• C. Chicken
• D. Peanuts

Correct answer: C

Rationale: Chicken is the best source of protein among the options provided. It is a lean source of protein and contains essential amino acids needed for the body. Eggs are also a good source of protein, but chicken typically contains more protein per serving compared to eggs. Peanuts are a good source of plant-based protein, but chicken provides a higher amount of protein and is usually leaner. Yams, while nutritious, are not a significant source of protein compared to chicken, eggs, or peanuts.

5. 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.
