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 healthcare professional has just inserted an NG tube for a client who is to start enteral tube feedings. Which of the following actions should the healthcare professional take to verify tube placement?

A. Measure the tube length.
B. Obtain an abdominal x-ray.
C. Flush the tube with 20 mL of water.
D. Auscultate the client’s lungs.

Correct answer: B

Rationale: Obtaining an abdominal x-ray is the most accurate method to verify the correct placement of an NG tube. Measuring the tube length is not a reliable method to confirm placement as it may vary among individuals. Flushing the tube with water and auscultating the client's lungs are not definitive methods to ensure proper NG tube placement.

3. What physiological role does phosphorus play in the body?

A. Blood clotting, transmission of nerve impulses, muscle contraction, and relaxation
B. Calcium homeostasis, structural integrity of heart muscle
C. No known metabolic function, caries-preventing properties
D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance

Correct answer: D

Rationale: The correct answer is D. Phosphorus plays a crucial role in ATP energy release, the metabolism of fats, carbohydrates, and proteins, and regulation of acid-base balance. Choices A, B, and C are incorrect. Phosphorus is not directly involved in blood clotting, transmission of nerve impulses, muscle contraction, or calcium homeostasis. It also has known metabolic functions and is not associated with caries prevention.

4. A nurse is planning teaching for the parents of a toddler who follows a vegetarian diet. The nurse should plan to include which of the following foods as the best source of dietary protein for the child?

A. Soy milk
B. Peanut butter
C. Dried beans
D. Whole grains

Correct answer: C

Rationale: Dried beans are the best source of dietary protein for a toddler following a vegetarian diet. They are rich in protein and other essential nutrients. Soy milk, while a good source of protein, may not provide as much protein density as dried beans. Peanut butter is a good source of protein but may not be as protein-dense as dried beans. Whole grains are not as high in protein content compared to dried beans, making them a less optimal choice for meeting the toddler's protein needs.

5. Which medical problem is not generally associated with malnutrition?

A. incontinence
B. pressure sores
C. celiac disease
D. major surgery

Correct answer: A

Rationale: Incontinence is not typically associated with malnutrition, whereas conditions like pressure sores and celiac disease are directly linked to nutritional deficiencies and malabsorption.
