When teaching a mother about introducing solid foods to her child, which of the following indicates the earliest age at which this should be done?

Correct Answer: D

Rationale: Introducing solid foods to infants is an important milestone in their development, but it is crucial to do it at the right time to ensure their safety and proper growth. The correct answer is D) 4 months. At around 4 months of age, infants start showing signs of readiness for solid foods such as sitting up with support and displaying interest in what others are eating. Additionally, their digestive system is more developed by this age, making it easier for them to digest and absorb nutrients from solid foods. Option A) 1 month is too early to introduce solid foods as infants' digestive systems are not mature enough to handle anything other than breastmilk or formula. Option B) 2 months is also too early and can increase the risk of allergies and digestive issues. Option C) 3 months is still premature for introducing solids and may lead to choking hazards and nutritional imbalances. Educationally, it is important to provide parents with accurate information on the appropriate timing for introducing solid foods to prevent potential health risks and promote optimal growth and development in infants. By understanding the signs of readiness and following recommended guidelines, parents can ensure a smooth transition to solid foods for their child.

Correct Answer: C

Rationale: In pediatric respiratory distress, particularly in preterm neonates with respiratory distress syndrome (RDS), the preferred method of administering oxygen is nasal continuous positive airway pressure (CPAP). Rationale for choosing option C: 1. Nasal CPAP helps keep the airways open, improves oxygenation, and reduces the work of breathing in neonates with RDS. 2. It is less invasive compared to endotracheal intubation or mechanical ventilation, reducing the risk of complications such as ventilator-associated lung injury. 3. CPAP can be easily titrated to the neonate's respiratory needs, providing optimal respiratory support. Rationale for why others are incorrect: A) Oxygen hood: Less effective in providing consistent positive airway pressure and may not adequately support neonates with significant respiratory distress. B) Endotracheal intubation: Invasive procedure associated with risks of infection, airway trauma, and long-term respiratory issues in neonates. D) Mechanical ventilation: Should be considered if CPAP fails, as it is more invasive and associated with higher risks of complications, making it less preferred initially. Educational context: Understanding the appropriate respiratory interventions in pediatric patients is crucial for nurses caring for neonates with RDS. Knowing when to escalate or de-escalate respiratory support is vital in providing safe and effective care to this vulnerable population. Nasal CPAP is a valuable non-invasive tool that nurses should be familiar with, as it plays a key role in managing respiratory distress in preterm neonates.

Correct Answer: B

Rationale: In the context of nursing interventions for pediatric respiratory distress, the primary benefit of surfactant therapy in treating respiratory distress syndrome in preterm neonates is reducing surface tension in the alveoli, which is option B. Surfactant is a substance naturally produced in the lungs that helps reduce surface tension in the alveoli, preventing their collapse during exhalation and promoting lung compliance. In preterm neonates with respiratory distress syndrome, there is a deficiency of surfactant, leading to alveolar collapse and difficulty in breathing. By administering exogenous surfactant, healthcare providers can improve lung function by reducing surface tension, thereby preventing atelectasis and improving gas exchange. Option A, promoting lung growth, is not the primary benefit of surfactant therapy. While surfactant does support lung development by preventing alveolar collapse and promoting expansion, its primary function in this context is to reduce surface tension. Option C, improving oxygen uptake in the placenta, is incorrect as surfactant therapy directly impacts lung function and alveolar stability, not oxygen uptake in the placenta. Option D, decreasing blood pressure in the lungs, is also incorrect. Surfactant therapy primarily focuses on improving lung function and oxygenation by reducing surface tension in the alveoli, rather than directly affecting blood pressure in the lungs. Understanding the primary benefits and mechanisms of surfactant therapy in treating respiratory distress syndrome is crucial for nursing interventions in pediatric patients, especially preterm neonates, to provide effective and evidence-based care to improve respiratory outcomes.

Correct Answer: A

Rationale: In the scenario of a neonate experiencing a moderate to severe hypoxic episode after birth, the first-line treatment should be positive pressure ventilation (Option A). This intervention is crucial as it helps deliver oxygen to the infant's lungs and tissues, improving oxygenation and addressing the underlying cause of respiratory distress. Positive pressure ventilation is preferred over other options for several reasons. Endotracheal intubation (Option B) may be necessary if positive pressure ventilation is ineffective, but it is more invasive and carries risks of complications, making it a secondary choice. Chest compressions (Option C) are only indicated in cases of cardiac arrest, not primarily for respiratory distress. Oxygen therapy (Option D) alone may not provide sufficient support in cases of severe respiratory distress where ventilation is compromised. In an educational context, understanding the rationale behind the choice of positive pressure ventilation as the first-line treatment is essential for nurses caring for neonates in respiratory distress. It ensures timely and appropriate intervention to optimize outcomes and prevent further deterioration. Nurses must be competent in recognizing and managing respiratory distress in neonates to provide safe and effective care in critical situations.

Correct Answer: B

Rationale: In pediatric nursing, therapeutic play is a powerful tool to help children cope with medical procedures, express emotions, and promote healing. For a 4-year-old, imaginative play is crucial for emotional and cognitive development. Dress-up clothes best promote imaginative play among the options provided. Here's why: 1. **Correct Answer (B - Dress-up clothes):** Dress-up clothes allow a child to role-play different characters, scenarios, and professions, fostering creativity and imagination. Through this type of play, a child can express feelings, explore social roles, and make sense of their experiences in a safe and enjoyable way. 2. **Why Others Are Wrong:** - **A) Large blocks:** While blocks are great for building and fine motor skills, they do not specifically promote imaginative play as effectively as dress-up clothes. - **C) Wooden puzzle:** Puzzles are beneficial for problem-solving and cognitive skills but do not offer the same imaginative play opportunities as dress-up clothes. - **D) Big wheels:** While riding toys like big wheels can be fun and promote physical activity, they do not directly support imaginative play or emotional expression like dress-up clothes. 3. **Educational Context:** Understanding the developmental needs of children is essential in pediatric nursing. By providing appropriate toys for therapeutic play, nurses can support children in coping with stress, anxiety, and medical procedures. Encouraging imaginative play through tools like dress-up clothes can enhance a child's emotional well-being and overall hospital experience.
