Nursing Elites

1. Each of the following accurately describes aspects of the dietary reference intakes (DRIs) published by the Food and Nutrition Board of the Institute of Medicine (IOM) except one. Which one is the exception?

• A. The DRIs replace the older recommended daily allowances
• B. Current DRIs attempt to estimate required nutrients to improve long-term health
• C. DRIs specifically address individuals whose requirements are affected by a disease state
• D. The DRIs attempt to establish maximum safe levels of tolerance for nutrients

Correct answer: C

Rationale: The correct answer is C. DRIs are intended for the general population and do not specifically address disease states, which are managed with different clinical guidelines. Choice A is correct as DRIs have replaced the older recommended daily allowances. Choice B is correct as current DRIs aim to estimate the required nutrients for long-term health. Choice D is correct as DRIs also attempt to establish maximum safe levels of tolerance for nutrients.

2. This study, which is an in-depth study of one boy, is a:

• A. case study
• B. longitudinal study
• C. cross-sectional study
• D. evaluative study

Correct answer: A

Rationale: The correct answer is 'A: case study.' A case study involves an in-depth examination of a single individual, group, or event. In this scenario, focusing on one boy aligns with the definition of a case study. The other options are not applicable: B) A longitudinal study involves following subjects over a period of time, C) A cross-sectional study examines a population at a single point in time, and D) An evaluative study assesses the effectiveness of a program or intervention, which is not the focus of the given scenario.

3. A nurse is providing teaching to a group of parents of newborns who are planning to formula feed. Which of the following statements by a parent indicates a need for further teaching?

• A. "I will give formula to my baby at room temperature."
• B. "I will ensure my baby's feeds last 10 to 15 minutes."
• C. "I will burp my baby halfway through each feeding."
• D. "I will watch for signs my baby is full and stop the feeding."

Correct answer: B

Rationale: The correct answer is, "I will ensure my baby's feeds last 10 to 15 minutes." This statement indicates a need for further teaching because it suggests a strict time limit for feedings, which may not be appropriate for a newborn. Newborns should be allowed to feed as long as they want, typically around 20-30 minutes per breast if breastfeeding, or on-demand with formula. Choices A, C, and D demonstrate proper feeding practices such as feeding at room temperature, burping halfway through each feeding, and watching for signs of fullness to stop the feeding, which are all appropriate responses by a parent of a formula-fed newborn.

4. What is a major goal for home care nurses?

• A. Restoring maximum health function.
• B. Promoting the health of populations.
• C. Minimizing the progress of disease.
• D. Maintaining the health of populations.

Correct answer: A

Rationale: A major goal for home care nurses is restoring maximum health function. This involves helping patients achieve their highest level of health and independence, focusing on individualized care plans tailored to each patient's needs. Choice B, promoting the health of populations, is more aligned with public health nursing rather than home care nursing. Choice C, minimizing the progress of disease, is important but not as comprehensive as restoring maximum health function. Choice D, maintaining the health of populations, is more about preventive care at a population level rather than the individualized care provided by home care nurses.

5. Which bond is formed by a positively charged metal ion and negatively charged nonmetal ion?

• A. Ionic bond
• B. Covalent bond
• C. Functional group
• D. Metallic bond

Correct answer: A

Rationale: The correct answer is an ionic bond. An ionic bond is formed when a positively charged metal ion joins with a negatively charged nonmetal ion, resulting in a transfer of electrons. In contrast, a covalent bond involves sharing electrons between atoms rather than complete transfer. Functional groups are specific groups of atoms within molecules that determine the molecule's chemical properties. Metallic bonds occur between metal atoms where electrons are shared across a delocalized electron cloud.
