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. An adolescent states, “I want to be a doctor or a lawyer when I grow up because I like taking care of people.” Which Eriksonian challenge is the adolescent attempting?

• A. Identity vs. role diffusion
• B. Trust vs. mistrust
• C. Industry vs. inferiority
• D. Autonomy vs. shame and doubt

Correct answer: A

Rationale: The correct answer is A: Identity vs. role diffusion. During adolescence, individuals face the challenge of forming a cohesive sense of self and identity. In this scenario, the adolescent's desire to become a doctor or lawyer reflects the exploration of potential roles and career paths, indicating an attempt to establish a clear identity. Choices B, C, and D are incorrect. Trust vs. mistrust is a challenge experienced in infancy, industry vs. inferiority is relevant to the school-age period, and autonomy vs. shame and doubt is associated with the toddler stage, not adolescence.

3. Ongoing fluid losses can overwhelm the child’s ability to compensate, resulting in shock. What early clinical sign precedes shock?

• A. Tachycardia
• B. Slow respirations
• C. Warm, flushed skin
• D. Decreased blood pressure

Correct answer: A

Rationale: Tachycardia is an early sign of shock as the body tries to maintain cardiac output in the face of declining circulatory volume. Blood pressure often remains normal until late in the progression, at which point decompensated shock is occurring.

4. The nurse is planning a teaching session to adolescents about deaths by unintentional injuries. Which should the nurse include in the session with regard to deaths caused by injuries?

• A. More deaths occur in males
• B. More deaths occur in females
• C. The pattern of deaths does not vary according to age and sex
• D. The pattern of deaths does not vary widely among different ethnic groups

Correct answer: A

Rationale: More deaths due to unintentional injuries occur in males, which may be due to higher risk-taking behaviors.

5. Which parental statement indicates correct understanding of information presented regarding the prevention of iron deficiency anemia in infants?

• A. "We will add green leafy vegetables to our child’s low-iron formula."
• B. "We will discontinue the use of vitamin C supplements by 6 months of age."
• C. "We will begin an iron-fortified infant cereal at 4 to 6 months of age."
• D. "We will introduce cow’s milk by 6 months of age."

Correct answer: C

Rationale: The correct answer is C. Introducing iron-fortified cereal between 4 to 6 months of age is a recommended practice to prevent iron deficiency anemia in infants. Iron-fortified infant cereals are a good source of iron for infants. Choices A and B are incorrect because adding green leafy vegetables to low-iron formula and discontinuing vitamin C supplements do not directly address the prevention of iron deficiency anemia. Choice D is incorrect because cow's milk should be avoided before 12 months of age as it is low in iron and can lead to intestinal blood loss, increasing the risk of iron deficiency anemia.
