Nursing Elites

1. Which parameter correlates best with measurements of total muscle mass?

• A. Height
• B. Weight
• C. Skinfold thickness
• D. Upper arm circumference

Correct answer: D

Rationale: Upper arm circumference correlates best with total muscle mass because it includes both muscle and fat components, making it a reliable indicator of muscle mass.

2. Which condition is often associated with a "ground-glass" appearance on a chest x-ray in neonates?

• A. Pneumonia
• B. Respiratory distress syndrome
• C. Bronchopulmonary dysplasia
• D. Congenital diaphragmatic hernia

Correct answer: B

Rationale: The correct answer is B, Respiratory distress syndrome. Respiratory distress syndrome often presents with a "ground-glass" appearance on a chest x-ray in neonates due to surfactant deficiency. Choice A, Pneumonia, typically appears as patchy infiltrates on chest x-ray. Choice C, Bronchopulmonary dysplasia, is characterized by hyperinflation and fibrosis, not a ground-glass appearance. Choice D, Congenital diaphragmatic hernia, usually shows mediastinal shift and bowel loops in the chest cavity on x-ray, not a ground-glass appearance.

3. Which inpatient pediatric patient would not be able to go to the playroom due to their physical condition?

• A. A 4-year-old with chickenpox
• B. A 12-year-old with a fractured femur
• C. A 7-year-old with new-onset diabetes mellitus
• D. A 10-year-old postoperative appendectomy

Correct answer: A

Rationale: The correct answer is A. A child with chickenpox should not go to the playroom due to being contagious, as the virus can easily spread to other children. Children with fractures (choice B), new-onset diabetes mellitus (choice C), or postoperative appendectomy (choice D) do not pose a risk of spreading an infectious disease, so they can safely go to the playroom.

4. The nurse is assessing a 3-year-old African American child whose height and weight are at the 20th percentile on the growth chart. What should the nurse recognize?

• A. The data suggest the child requires nutritional intervention
• B. The NCHS charts are accurate for U.S. African American children
• C. A correction factor is used for nonwhite ethnic groups
• D. No assessment can be made until several measurements are plotted over time

Correct answer: B

Rationale: The NCHS growth charts serve as reference guides for all racial or ethnic groups, including African American children. The 20th percentile for height and weight does not indicate nutritional failure but provides a reference point for ongoing assessment. Choice A is incorrect because being at the 20th percentile does not automatically imply the need for nutritional intervention. Choice C is incorrect as there is no correction factor specifically used for nonwhite ethnic groups in this context. Choice D is incorrect as a single measurement at the 20th percentile can provide valuable information for assessment.

5. The educator is teaching about the process of physical growth and development. Which of these describes the directional pattern from head to tail?

• A. Cephalodistal
• B. Cephalocaudal
• C. Proximodistal
• D. Proximocaudal

Correct answer: B

Rationale: Cephalocaudal development is the correct term that describes the directional pattern of growth from head to tail. This means that the head and upper body parts develop before the lower parts. Choice A, 'Cephalodistal,' refers to growth from the center of the body outward, not head to tail. Choice C, 'Proximodistal,' describes growth from the center of the body towards the extremities, not specifically from head to tail. Choice D, 'Proximocaudal,' is not a recognized term in the context of physical growth and development.
