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. Parents of a newborn with ambiguous genitalia want to know how long they will have to wait to know whether they have a boy or a girl. The nurse answers the parents based on what knowledge?

• A. Chromosome analysis will be complete in 7 days.
• B. A physical examination will be able to provide a definitive answer.
• C. Additional laboratory testing is necessary to assign the correct gender.
• D. Gender assignment involves collaboration between the parents and a multidisciplinary team.

Correct answer: D

Rationale: Gender assignment in cases of ambiguous genitalia is a complex process that requires a multidisciplinary approach, including genetic, endocrinological, and psychological evaluations. The decision should be made collaboratively with the parents.

3. Which immunization is typically administered at birth?

• A. Hepatitis B
• B. DTaP
• C. MMR
• D. Varicella

Correct answer: A

Rationale: The correct answer is A, Hepatitis B. The Hepatitis B vaccine is usually given at birth to protect against hepatitis B, a virus that can lead to chronic liver disease and liver cancer. This vaccination is crucial for newborns, especially those born to mothers who are carriers of hepatitis B. Choices B, C, and D are incorrect because DTaP (B), MMR (C), and Varicella (D) vaccines are not typically administered at birth. DTaP is given in a series starting at 2 months, MMR is usually given around 12-15 months, and Varicella is given between 12-15 months of age.

4. A child with pyloric stenosis is having excessive vomiting. The nurse should assess for what potential complication?

• A. Hyperkalemia
• B. Hyperchloremia
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: D

Rationale: Excessive vomiting in pyloric stenosis leads to the loss of stomach acid (hydrochloric acid), resulting in metabolic alkalosis, not hyperkalemia, hyperchloremia, or metabolic acidosis. Metabolic alkalosis is characterized by a higher pH level in the blood due to the loss of acid and a relative increase in bicarbonate. Hyperkalemia is an elevated level of potassium in the blood and is not directly related to excessive vomiting in pyloric stenosis. Hyperchloremia is an excess of chloride in the blood, which is not typically associated with this condition. Metabolic acidosis is a condition characterized by a lower pH level in the blood, caused by an excess of acid or a loss of bicarbonate, which is not the typical complication seen in pyloric stenosis with excessive vomiting.

5. What information should be given to the parents of a 12-month-old child regarding appropriate play activities for this age?

• A. Give large push-pull toys for kinetic stimulation
• B. Place a cradle gym across the crib to help develop fine motor skills
• C. Provide the child with finger paints to enhance fine motor skills
• D. Provide a stick horse to develop gross motor coordination

Correct answer: A

Rationale: Large push-pull toys are suitable for a 12-month-old as they encourage gross motor skills and physical activity, which are crucial for their development at this age.
