1. Which of the following converts starch to disaccharides, and this reaction occurs in the _____?
- A. pancreatic amylases, small intestine
- B. brush border enzymes, small intestine
- C. luminal enzymes, large intestine
- D. pancreatic amylases, pancreas
Correct answer: A
Rationale: The correct answer is A. Pancreatic amylases break down starch into disaccharides in the small intestine. This process occurs in the small intestine, not the large intestine or pancreas. Brush border enzymes act on disaccharides to break them down into monosaccharides, while luminal enzymes are not specifically involved in the conversion of starch to disaccharides.
2. The nurse knows that after receiving the blood from the blood bank, it should be administered within:
- A. 1 hour
- B. 2 hours
- C. 4 hours
- D. 6 hours
Correct answer: D
Rationale: Blood transfusions need to be administered promptly after receiving the blood from the blood bank to ensure patient safety and effectiveness. Waiting too long can lead to complications such as bacterial growth in the blood product, which can be harmful when infused. Administering the blood within 6 hours is crucial to prevent such risks. Choices A, B, and C are incorrect because waiting for 1, 2, or 4 hours respectively can increase the likelihood of complications associated with delayed transfusion.
3. Reducing the amount of trans fat in the diet is an effective method of decreasing the risk of CHD. Which food is most likely a source of trans fat?
- A. hot dogs
- B. whole milk
- C. fatty fish
- D. potato chips
Correct answer: D
Rationale: The correct answer is D: potato chips. Potato chips, especially when fried in hydrogenated oils, are a common source of trans fats, which are linked to an increased risk of coronary heart disease (CHD). Hot dogs (choice A) can also contain trans fats if made with processed meats and added fats. Whole milk (choice B) and fatty fish (choice C) do not typically contain trans fats, making them less likely sources compared to potato chips.
4. A nurse is providing teaching to a group of older adults about sources of complete and incomplete protein. Which of the following foods should the nurse include as a complete protein?
- A. Yogurt
- B. Fresh vegetables
- C. Nuts
- D. Dried Beans
Correct answer: A
Rationale: Yogurt is the correct answer as it is a complete protein source, containing all nine essential amino acids. Fresh vegetables, nuts, and dried beans are incomplete protein sources as they lack one or more essential amino acids required by the body.
5. A nurse is preparing to administer a gavage feeding via a nasogastric tube to a preterm newborn who is receiving supplemental oxygen. Which of the following actions should the nurse take?
- A. Stabilize the tube with tape to the newborn’s cheek.
- B. Remove supplemental oxygen during the feeding.
- C. Measure the stomach aspirate prior to the feeding.
- D. Place the newborn on their left side for 30 minutes after the feeding.
Correct answer: C
Rationale: Measuring the stomach aspirate prior to the feeding is crucial to ensure the correct placement and function of the nasogastric tube. This step helps prevent complications such as aspiration or improper feeding. Choice A is incorrect as stabilizing the tube with tape to the newborn’s cheek can cause discomfort and skin irritation. Choice B is incorrect because removing supplemental oxygen during the feeding may compromise the newborn's respiratory status. Choice D is incorrect because placing the newborn on their left side for 30 minutes after the feeding is not a standard practice and is unnecessary for administering gavage feeding.
