1. Patients maintained using peritoneal dialysis may gain weight because:
- A. their appetite is increased
- B. physical activity is limited
- C. they absorb glucose from the dialysate
- D. they absorb amino acids from the dialysate
Correct answer: C
Rationale: Glucose from the peritoneal dialysis solution can be absorbed into the bloodstream, leading to weight gain if not balanced with diet and activity.
2. During early tooth development, vitamin A deficiency leads to enamel hypoplasia and defective dentin formation. Because of its effect on soft tissues and bone, vitamin A contributes to normal spacing of teeth.
- A. Both statements are true.
- B. Both statements are false.
- C. The first statement is true; the second is false.
- D. The first statement is false; the second is true.
Correct answer: A
Rationale: Both statements are true. The effect of vitamin A on the growth of soft tissues and bones naturally extends to the teeth and surrounding structures. Enamel hypoplasia, involving defective enamel matrix and incomplete calcification of enamel and dentin, can be due to vitamin A deficiency. The effect of this vitamin upon surrounding bone directly affects spacing patterns of the teeth within the bone and dentition. Choice A is correct because both statements accurately describe the influence of vitamin A on tooth development. Choices B, C, and D are incorrect as they do not reflect the accuracy of the statements provided.
3. Where in the body are microvilli located, facilitating the absorption of most nutrients?
- A. Stomach
- B. Pancreas
- C. Large Intestine
- D. Small Intestine
Correct answer: D: Small Intestine
Rationale: The correct answer is D: Small Intestine. Microvilli are present in the small intestine, significantly increasing its surface area for efficient absorption of nutrients. The small intestine is the primary site for nutrient absorption in the body. The stomach (choice A) primarily functions to break down food with its acidic environment but is not where most nutrients are absorbed. The pancreas (choice B) produces enzymes to aid in digestion but does not directly absorb nutrients. The large intestine (choice C) mainly absorbs water and electrolytes from undigested food, rather than nutrients.
4. A patient is being discharged with a vitamin K deficiency. What food should the nurse recommend to the patient to include in their diet?
- A. Oranges
- B. Spinach
- C. Fish
- D. Nuts
Correct answer: B
Rationale: Spinach is an excellent source of vitamin K, which plays a vital role in blood clotting and bone health. Oranges, fish, and nuts do not contain significant amounts of vitamin K, making them less suitable choices to address a vitamin K deficiency. Therefore, the correct recommendation for a patient with a vitamin K deficiency would be to include spinach in their diet to help replenish this essential vitamin.
5. Which is the best description of a full-liquid diet?
- A. Most suitable for individuals with an ileostomy
- B. Suitable for individuals with lactose intolerance
- C. Contains low saturated fat and high fiber
- D. Provides adequate nutrients and is easily digested
Correct answer: D
Rationale: The correct answer is D because a full-liquid diet is designed to provide adequate nutrients while being easily digested. Choices A and B are incorrect because a full-liquid diet is not specifically tailored for individuals with an ileostomy or lactose intolerance. Choice C is also incorrect as it describes characteristics that are not defining features of a full-liquid diet.
