Nursing Elites

1. What is the most critical physiologic change required of newborns at birth?

• A. Transition from fetal to neonatal breathing
• B. Body temperature maintenance
• C. Stabilization of fluid and electrolytes
• D. Closure of fetal shunts in the heart

Correct answer: A

Rationale: The correct answer is A: Transition from fetal to neonatal breathing. The onset of breathing is the most immediate and critical physiologic change required for the transition to extrauterine life. Factors that interfere with this normal transition increase fetal asphyxia, which is a condition of hypoxemia, hypercapnia, and acidosis. While body temperature maintenance, stabilization of fluid and electrolytes, and closure of fetal shunts in the heart are crucial changes in the transition to extrauterine life, breathing and the exchange of oxygen for carbon dioxide must take precedence as they are essential for newborn survival.

2. Which food should be introduced first to a 6-month-old infant?

• A. Fruits
• B. Eggs
• C. Vegetables
• D. Meat

Correct answer: C

Rationale: Vegetables, particularly pureed ones, are often recommended as a first solid food for infants because they are easy to digest and less likely to cause allergies. Fruits can be introduced later due to their natural sweetness, while eggs and meat are typically introduced after fruits and vegetables as they may pose a higher risk of allergies.

3. What is the best age to introduce solid food into an infant’s diet?

• A. 2 to 3 months
• B. 4 to 6 months
• C. When birth weight has tripled
• D. When tooth eruption has started

Correct answer: B

Rationale: The introduction of solid foods is recommended at 4 to 6 months when the infant's digestive system is more developed and ready for solids.

4. When the nurse interviews an adolescent, which is especially important?

• A. Focus the discussion on the peer group
• B. Allow an opportunity to express feelings
• C. Use the same type of language as the adolescent
• D. Emphasize that confidentiality will always be maintained

Correct answer: B

Rationale: Allowing adolescents to express their feelings helps them feel heard and supported, which is crucial for effective communication.

5. 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.
