1. An elderly man is hospitalized with a diagnosis of malnutrition three months following his wife's death. What risk factor for malnutrition does this scenario illustrate?

• A. A history of chronic illness
• B. Depression or social isolation
• C. Age
• D. Impaired mobility

Correct answer: B

Rationale: This scenario illustrates depression or social isolation as a risk factor for malnutrition. After the death of his wife, the elderly man may have experienced depression or social isolation, which can lead to decreased food intake and poor nutritional status. Although age, chronic illness, and impaired mobility can also contribute to malnutrition, they are not the primary factors described in this scenario. The history of chronic illness (Choice A) and impaired mobility (Choice D) were not mentioned in the scenario, and while age (Choice C) is a factor, it's not the main factor depicted in this case.

2. What percentage of body weight as fat does a woman with a healthy body composition typically average?

• A. 5%
• B. 15%
• C. 25%
• D. 35%

Correct answer: C

Rationale: A healthy body fat percentage for women typically ranges between 21% and 33%, with 25% being an average healthy body fat percentage. Choice A (5%) is too low for a healthy body fat percentage and is more in line with essential body fat levels. Choice B (15%) is also lower than the typical range for a healthy body fat percentage. Choice D (35%) is too high and would be considered high body fat for women.

3. Hypertrophic burn scars are caused by:

• A. exaggerated contraction
• B. random layering of collagen
• C. wound ischemia
• D. delayed epithelialization

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

4. When rickets occurs, how is the alveolar bone affected compared to other bones in the body?

• 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: A

Rationale: Both statements are true. When rickets occurs, the alveolar bone is affected similar to other bones in the body, with the trabeculae of the alveolar bone also weakening. In addition to damaged alveolar bone caused by vitamin D deficiency, dental changes include delayed dentition and small molars. The other choices are incorrect because both statements provided are accurate based on the effects of rickets on the alveolar bone.

5. Which is most likely to initiate periodontal disease?

• A. Nutrient deficiencies
• B. Nutrient excesses
• C. Nutrient imbalances
• D. Plaque biofilm

Correct answer: D

Rationale: Plaque biofilm is the primary initiator of periodontal disease, as it harbors bacteria that can lead to inflammation and destruction of the periodontal tissues.
