NR228/NR 228 Exam 1 V2 | Nutrition, Health &
Wellness Q&A with Rationale | Chamberlain
University
1. A nurse is conducting a community health seminar on health literacy. Which definition
should the nurse provide to explain this concept effectively?
A. The ability to memorize medical terminology and drug names
B. The skill required to perform self-injections and wound care
C. The capacity to obtain, process, and understand basic health information
D. The educational level attained by a healthcare professional
Correct Answer: C
Explanation: Health literacy involves the ability of individuals to access and interpret
health information to make informed decisions. It is a critical component in ensuring
patient safety and adherence to treatment plans. Nurses must assess a patient’s literacy
level to tailor education effectively.
2. A patient is recovering from a stroke and is participating in physical therapy to regain
mobility. The nurse identifies this as which level of prevention?
A. Primary prevention
B. Secondary prevention
C. Quaternary prevention
,D. Tertiary prevention
Correct Answer: D
Explanation: Tertiary prevention focuses on rehabilitation and minimizing the effects of a
long-term disease or injury. It aims to improve the quality of life and reduce disability after
a diagnosis is made. Physical therapy after a stroke is a classic example of this level of care.
3. When calculating the caloric intake of a meal, the nurse knows that which macronutrient
provides the highest energy density per gram?
A. Carbohydrates
B. Lipids
C. Alcohol
D. Proteins
Correct Answer: B
Explanation: Lipids, or fats, provide 9 kilocalories per gram, making them the most
energy-dense macronutrient. In contrast, carbohydrates and proteins provide only 4
kilocalories per gram. This information is vital for weight management and nutritional
counseling.
4. A client is confused about the difference between Recommended Dietary Allowances
(RDA) and Adequate Intake (AI). Which explanation by the nurse is correct?
A. AI is only applicable to vitamins, while RDA is for minerals
, B. RDA is the maximum amount of a nutrient that is safe to consume
C. AI is used when there is insufficient evidence to establish an RDA
D. RDA is based on subjective data, while AI is based on clinical trials
Correct Answer: C
Explanation: The Adequate Intake (AI) is used as a goal for nutrient intake when scientific
data are insufficient to determine an RDA. Both are components of the Dietary Reference
Intakes (DRIs) used to plan and assess diets. The RDA is based on solid experimental
evidence to meet the needs of nearly all healthy individuals.
5. During the assessment of a middle-aged client, the nurse notes a diet high in refined
sugars. The nurse should explain that these are classified as:
A. Complex carbohydrates
B. Polysaccharides
C. Insoluble fibers
D. Simple carbohydrates
Correct Answer: D
Explanation: Simple carbohydrates consist of monosaccharides and disaccharides that are
quickly absorbed by the body. They often provide ‘empty calories’ without significant fiber
or vitamins. Excess consumption of simple sugars is linked to various metabolic health
issues.
