ATI Nutrition Practice A
1. Which organ absorbs water and vitamin K and may be affected by ulcerative colitis?
- A. Stomach
- B. Pancreas
- C. Large intestine
- D. Small intestine
Correct answer: C
Rationale: The large intestine is the organ that is primarily responsible for the absorption of water and vitamin K in the human body. A disease like ulcerative colitis can disrupt these functions by causing inflammation and ulcers in the lining of the large intestine, leading to digestive issues. The stomach (Choice A) primarily functions to break down and digest food, not to absorb water and vitamins. The pancreas (Choice B) secretes enzymes to aid in digestion and hormones to regulate blood sugar, but does not absorb water and vitamins. The small intestine (Choice D) is primarily responsible for absorbing nutrients from digested food, but not specifically water and vitamin K. Therefore, these other choices are incorrect.
2. A nurse is caring for a client with a major burn injury and is receiving TPN. Which of the following lab tests is the priority for the nurse to use to confirm the client is receiving adequate nutrition?
- A. Iron
- B. Magnesium
- C. Folic acid
- D. Prealbumin
Correct answer: D
Rationale: Prealbumin is a sensitive indicator of protein status and nutrition, making it a priority for assessing nutritional adequacy in clients receiving TPN. Iron, magnesium, and folic acid levels are important for overall health but do not specifically indicate nutritional adequacy in the context of TPN administration.
3. A nurse is providing teaching to the parent of an infant about introducing solid foods. The nurse should recommend that which of the following foods be introduced first?
- A. Strained fruits
- B. Pureed meats
- C. Cooked egg whites
- D. Iron-fortified cereal
Correct answer: D
Rationale: When introducing solid foods to infants, it is recommended to start with iron-fortified cereal as it is easily digestible and a good source of iron, an important nutrient for infants around 6 months of age. Strained fruits are usually introduced later due to their natural sugars. Pureed meats can be introduced after iron-fortified cereals to provide additional protein and iron. Cooked egg whites should be avoided until the infant is at least one year old to reduce the risk of allergies.
4. A nurse is providing teaching to a client who has type 1 diabetes mellitus. Which of the following statements by the client indicates an understanding of the teaching?
- A. Albumin in my urine is an indication of normal kidney function.
- B. I will keep my HbA1c at five percent.
- C. I will have ketones in my urine if my blood glucose is maintained at 190 milligrams per deciliter.
- D. I will keep my blood glucose levels between 200 and 212 milligrams per deciliter.
Correct answer: B
Rationale: The correct answer is B. Maintaining an HbA1c level of 5 percent indicates good long-term blood glucose control and understanding of diabetes management. Choice A is incorrect because the presence of albumin in the urine (albuminuria) is actually an indication of kidney damage in diabetes. Choice C is incorrect as ketones in the urine are a sign of inadequate insulin and can occur when blood glucose levels are high, not at a specific level like 190 mg/dL. Choice D is also incorrect as the client should aim to keep blood glucose levels within a tighter range for better control, typically between 80-130 mg/dL before meals and less than 180 mg/dL after meals.
5. The substance that is most supportive of bones and teeth is:
- A. Hemoglobin
- B. Collagen
- C. Insulin
- D. Pepsin
Correct answer: B
Rationale: Collagen is a key structural protein in bones and teeth, providing support and strength.
