1. 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.
2. Which nursing diagnosis has nutritional implications?
- A. impaired dentition
- B. disruption of gas exchange
- C. self-esteem disturbance
- D. sleep pattern disturbance
Correct answer: A
Rationale: Impaired dentition affects a patient's ability to chew and consume a variety of foods, leading to potential nutritional deficiencies and malnutrition.
3. A nurse is caring for a client who has a body mass index (BMI) of 30. Four weeks after nutritional counseling, which of the following evaluation findings indicates the plan of care was followed?
- A. BMI of 25
- B. Weight gain of 1.8 kg
- C. BMI of 33
- D. Weight loss of 2.7 kg
Correct answer: D
Rationale: A weight loss of 2.7 kg in four weeks indicates effective adherence to a nutritional plan aimed at reducing body mass index (BMI), moving towards a healthier weight. Choices A, B, and C are incorrect because a decrease in weight, as shown in choice D, is the desired outcome when managing a client with a BMI of 30 to reach a healthier range.
4. Uric acid kidney stones are most commonly associated with what condition?
- A. diabetes
- B. hypercalcemia
- C. gout
- D. diarrhea
Correct answer: C
Rationale: Gout is a condition characterized by high levels of uric acid, which can lead to the formation of uric acid kidney stones due to the crystallization of uric acid in the kidneys.
5. Which group is least susceptible to insufficient intake of protein?
- A. The elderly
- B. Individuals with low income
- C. Adults participating in endurance exercise
- D. Patients who are chronically ill
Correct answer: C
Rationale: Adults who participate in endurance exercise are typically more aware of their nutritional needs and have higher protein intake compared to other groups. The rationale behind why the other choices are incorrect is as follows: A: The elderly are often at a higher risk of insufficient protein intake due to various factors such as reduced appetite, dental issues, and decreased muscle mass. B: Individuals with low income may struggle to afford protein-rich foods, making them more susceptible to insufficient protein intake. D: Patients who are chronically ill may have specific dietary restrictions or challenges that can lead to inadequate protein consumption.
