1. What is the function of villi and microvilli in the GI tract?
- A. produce bile
- B. kill bacteria
- C. produce vitamin K
- D. increase the surface area for absorption
Correct answer: D
Rationale: Villi and microvilli in the GI tract serve to increase the surface area of the small intestine, aiding in the absorption of nutrients into the bloodstream. Choices A, B, and C are incorrect as villi and microvilli are primarily involved in enhancing absorption, not in producing bile, killing bacteria, or producing vitamin K.
2. A nurse in a long-term care facility is developing strategies to promote increased food intake for an older adult client. Which of the following interventions should the nurse implement?
- A. Offer sugar substitutes to increase the client’s appetite.
- B. Provide opportunities to eat three large meals per day.
- C. Provide entertainment while the client is eating.
- D. Offer finger foods at mealtime.
Correct answer: D
Rationale: The correct intervention for promoting increased food intake for an older adult client is to offer finger foods at mealtime. Finger foods are easier for older adults to manage, making eating less cumbersome and more enjoyable, which can help increase overall food intake. Providing sugar substitutes (Choice A) may not necessarily increase appetite and could have negative health effects. Eating three large meals per day (Choice B) may be overwhelming and not suitable for older adults who may prefer smaller, more frequent meals. While providing entertainment (Choice C) during meals can be beneficial in some cases, it may not directly contribute to increased food intake as effectively as offering finger foods.
3. Which of the following statements are correct?
- A. Lipids are transported in the blood as lipoproteins, which are clusters of lipids associated with proteins.
- B. In type II diabetes, the pancreas produces insulin, but cells are resistant to this signal.
- C. The glycemic index classifies foods based on their potential to raise blood glucose levels.
- D. All of the above
Correct answer: D
Rationale: Option A is correct because lipoproteins indeed transport lipids in the blood. They are complexes of lipids and proteins that transport water-insoluble lipids through the blood. Option B is correct as it accurately describes the condition of type II diabetes where the pancreas can produce insulin, but the cells are resistant to its signal, causing an ineffective regulation of blood sugar. Option C is also correct because the glycemic index is indeed a classification system for foods based on their potential to raise blood glucose levels. High glycemic index foods raise blood glucose levels faster than low glycemic index foods. Hence, all the statements are correct, making option D the correct answer.
4. What is the first step in decontamination?
- A. Immediately applying a chemical decontamination foam to the area of contamination
- B. Thoroughly washing and rinsing the patient with soap and water
- C. Immediately applying personal protective equipment
- D. Removing the patient's clothing and jewelry, then rinsing the patient with water
Correct answer: D
Rationale: The correct first step in decontamination is to remove the patient's clothing and jewelry to prevent further exposure and then rinse the patient with water. This helps to eliminate any contaminants on the patient's body. Choice A is incorrect because applying a chemical decontamination foam should come after removing clothing. Choice B is incorrect as washing and rinsing the patient should follow the removal of clothing. Choice C is incorrect as personal protective equipment should be worn by the individual performing the decontamination, not applied to the patient.
5. What is the primary food safety concern for a patient undergoing chemotherapy?
- A. Possible food allergy reactions
- B. Possible food-drug interactions
- C. Possible pesticide residue
- D. Potential risk of foodborne illness
Correct answer: D
Rationale: The correct answer is D: Potential risk of foodborne illness. Patients undergoing chemotherapy have compromised immune systems, making them more susceptible to foodborne illnesses. Chemotherapy can reduce the count of white blood cells, which impairs the body's ability to fight off infections from bacteria or other pathogens that might be present in food. Therefore, the prevention of foodborne illnesses is a critical concern for these patients. Choices A, B, and C, while they represent valid concerns for food safety in general, are not the primary concern for patients undergoing chemotherapy. These patients are at a heightened risk of experiencing severe complications from foodborne illnesses, making it a more significant concern than potential food allergies, food-drug interactions, or pesticide residues.
