1. What is the digestive action of bile?
- A. It breaks down carbohydrates
- B. It breaks down proteins
- C. It breaks down lipids
- D. It aids in fat digestion
Correct answer: D
Rationale: Bile, which is produced by the liver and stored in the gallbladder, aids in the digestion of fats. It does this by emulsifying the fats, which makes them easier for the digestive enzymes, such as lipase, to break down. While choices A, B, and C could be seen as partially correct since fats are a type of lipid and the process of breaking down fats could be seen as breaking down lipids, the most accurate answer is D, as the primary function of bile is to aid in fat digestion, not the digestion of all types of lipids or the digestion of proteins or carbohydrates.
2. The following are all classes of nutrients except:
- A. protein
- B. fat
- C. carbs
- D. phytochemicals
Correct answer: D
Rationale: Phytochemicals are not considered a class of nutrients. While proteins, fats, and carbohydrates are essential macronutrients providing energy and structural support, phytochemicals are non-nutrient compounds found in plants that offer various health benefits but are not essential for sustaining life like the other three choices. Therefore, the correct answer is D.
3. Which of the following methods is the best method for determining nasogastric tube placement in the stomach?
- A. X-ray
- B. Observation of gastric aspirate
- C. Testing of pH of gastric aspirate
- D. Placement of external end of tube under water
Correct answer: A
Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
4. This quality is being demonstrated by a Nurse who raise the side rails of a confused and disoriented patient?
- A. Autonomy
- B. Responsibility
- C. Prudence
- D. Resourcefulness
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.
5. Which of the following proteins is iron a component of, responsible for the transport of oxygen in the bloodstream?
- A. hemoglobin
- B. transferrin
- C. myoglobin
- D. hepcidin
Correct answer: A
Rationale: The correct answer is A: hemoglobin. Hemoglobin is the protein found in red blood cells that is responsible for carrying oxygen from the lungs to the rest of the body. Iron is a crucial component of hemoglobin, binding to oxygen and allowing for its transport. Choice B, transferrin, is involved in iron transport in the blood but not in oxygen transport. Choice C, myoglobin, is a protein found in muscle cells that stores oxygen for muscle use, not transportation in the bloodstream. Choice D, hepcidin, is a peptide hormone that regulates iron absorption in the intestines and iron distribution in the body, but it is not directly involved in oxygen transport.
