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. Each statement is true regarding oral exposure to fermentable carbohydrates, except one. Which is the exception?
- A. Longer exposure leads to an increased risk of demineralization
- B. Longer exposure increases the opportunity for remineralization
- C. The Stephan curve illustrates pH changes within plaque after rinsing with a sugar solution
- D. The critical pH at which enamel decalcification occurs is 5.5 or less
Correct answer: B
Rationale: All the statements above are accurate about oral exposure to fermentable carbohydrates, except for option B. In fact, longer exposure to these carbohydrates decreases the opportunity for remineralization. This is because the process of demineralization, in which minerals are lost from the tooth enamel, is sped up by the presence of fermentable carbohydrates. The Stephan curve (option C) is a graph that demonstrates how the pH of dental plaque changes after a sugar rinse, usually dropping (becoming more acidic), which can lead to enamel decalcification. Option D is also accurate, as a pH of 5.5 or lower is the critical point at which enamel starts to decalcify.
3. You notice that Miss Kate, a bread vendor, receives and changes money, then holds the bread without washing her hands. As a nurse, what should you say to Miss Kate?
- A. Miss, don't touch the bread, I'll be the one to pick it up.
- B. Miss, please wash your hands before you pick up the bread.
- C. Miss, use a pick-up forceps when picking up the bread.
- D. Miss, your hands are dirty, I guess I'll try another bread shop.
Correct answer: B
Rationale: The correct answer is B, as it emphasizes the importance of hygiene in food handling, which is crucial to prevent the spread of germs and diseases. The other options do not address the root of the issue, which is the unhygienic handling of food. Option A avoids direct confrontation but does not educate the vendor on proper hygiene. Option C, although it suggests a hygienic method, may not be practical or available in all situations. Option D is an avoidance strategy rather than a way to address the problem.
4. Which statement indicates understanding of a low-fiber diet?
- A. I can cut up carrots and celery sticks for my lunch.
- B. I will eat a bran muffin for my mid-morning snack.
- C. I will have oatmeal with skim milk for my breakfast.
- D. I should choose canned peaches for my fruit serving.
Correct answer: D
Rationale: The correct answer is D because canned peaches are low in fiber compared to the other options provided. Option A contains high-fiber vegetables (carrots and celery), option B includes a bran muffin which is fiber-rich, and option C involves oatmeal which is also a good source of fiber. Therefore, choosing canned peaches aligns with a low-fiber diet.
5. While the client has a pulse oximeter on his fingertip, you notice that sunlight is shining on the area where the oximeter is. Your action will be to:
- A. Set and turn on the alarm of the oximeter
- B. Do nothing since there is no identified problem
- C. Cover the fingertip sensor with a towel or bedsheet
- D. Change the location of the sensor every four hours
Correct answer: B
Rationale: In this scenario, the correct action is to do nothing since there is no identified problem with the sunlight shining on the area where the oximeter is placed. The functionality of the oximeter is not affected by sunlight, so covering it or changing its location unnecessarily could disrupt the monitoring process. Setting the alarm or changing the sensor location every four hours is not indicated in this situation and may lead to unnecessary interventions. It's essential to assess the situation carefully and intervene only when necessary, ensuring that care provided is appropriate and effective.
