What does the nurse explain that a ventricular septal defect will allow?

Correct Answer: A

Rationale: In pediatric nursing, understanding congenital heart defects like ventricular septal defects (VSDs) is crucial. A VSD allows blood to shunt left to right, causing increased pulmonary flow and no cyanosis. This is because the higher pressure in the left ventricle pushes oxygenated blood through the defect into the right ventricle and out to the pulmonary circulation. This shunting of blood does not cause cyanosis because oxygen-rich blood is still reaching the systemic circulation. Option B is incorrect because if blood were to shunt right to left, it would bypass the lungs, resulting in decreased pulmonary flow and cyanosis due to poorly oxygenated blood entering the systemic circulation. Option C is incorrect as VSDs typically result in a left-to-right shunt due to the pressure differences between the ventricles. Option D is also incorrect because a VSD does not directly affect the pressure in the left atrium. Educationally, understanding the hemodynamics of VSDs is crucial for nurses caring for pediatric patients with congenital heart defects. Recognizing the impact of VSDs on pulmonary blood flow and oxygenation helps nurses provide appropriate interventions and education to support optimal outcomes for these patients.

Correct Answer: D

Rationale: In caring for a child with a suspected myocardial infarction, the nurse needs to assess the Electrocardiogram (ECG) and heart sounds first (Option D) for several reasons. Firstly, an ECG provides direct information about the electrical conduction system of the heart, which is crucial in diagnosing a myocardial infarction. Changes in the ECG, such as ST-segment elevation or depression, can indicate myocardial damage. Additionally, assessing heart sounds can reveal abnormalities such as murmurs, which may indicate structural issues in the heart contributing to the myocardial infarction. Prompt evaluation of these parameters can guide immediate interventions and help prevent further damage to the heart. Regarding why the other options are incorrect: - Option A: While monitoring blood pressure and heart rate is important in cardiac assessment, they are secondary to directly assessing the heart's electrical activity and structural integrity in this situation. - Option B: Chest pain and anxiety levels are important to assess in a myocardial infarction scenario, but they are secondary to obtaining objective data through an ECG and heart sounds. - Option C: Oxygen saturation and respiratory rate are vital signs that should be monitored, but they do not provide direct information about the heart's condition during a suspected myocardial infarction. In an educational context, understanding the priority assessments in pediatric cardiovascular emergencies like myocardial infarction is essential for nurses to provide timely and effective care to pediatric patients. By prioritizing the assessment of the ECG and heart sounds, nurses can quickly identify and respond to life-threatening cardiac conditions in children, ultimately improving patient outcomes.

Correct Answer: C

Rationale: The most important intervention when caring for a child with cystic fibrosis hospitalized with a respiratory infection is to provide respiratory treatments and postural drainage (Option C). This intervention is crucial because cystic fibrosis is a genetic disorder that affects the respiratory system by causing thick, sticky mucus to build up in the lungs. Respiratory treatments, such as chest physiotherapy and postural drainage, help to mobilize and clear this mucus, improving ventilation and preventing complications like infections and respiratory distress. Administering prescribed antibiotics (Option A) is important in treating respiratory infections in cystic fibrosis, but it is not the most critical intervention. Increasing fluid intake to help thin mucus (Option B) is beneficial in cystic fibrosis management but may not be the priority during an acute respiratory infection when the focus is on clearing the airways. Encouraging high-calorie, high-protein meals (Option D) is essential in cystic fibrosis to support growth and nutrition but is not the priority during a respiratory infection when the child may have difficulty eating due to respiratory distress. Educationally, understanding the pathophysiology of cystic fibrosis and the rationale behind respiratory treatments is crucial for nurses caring for pediatric patients with this condition. Emphasizing the importance of timely and appropriate interventions during respiratory infections can help prevent complications and improve outcomes for children with cystic fibrosis.

Correct Answer: C

Rationale: In pediatric nursing, the management of rheumatic fever is crucial to prevent recurrent episodes and long-term complications. The correct answer, C) 5 years, is based on current guidelines for the prophylactic treatment of rheumatic fever with penicillin G. Children recovering from rheumatic fever should receive monthly injections of penicillin G for at least 5 years to prevent the recurrence of Group A Streptococcal infections, which can trigger rheumatic fever. Option A) 1 year is incorrect because this duration is too short to provide adequate protection against recurrent infections. Option B) 2 years is also insufficient as it may not cover the critical period of vulnerability for the child. Option D) 10 years is too long as guidelines recommend prophylaxis for 5 years in most cases. Educationally, understanding the rationale behind the duration of prophylactic treatment in rheumatic fever is essential for pediatric nurses to provide optimal care to these patients. By grasping the importance of long-term antibiotic prophylaxis, nurses can help prevent complications and improve the quality of life for children recovering from rheumatic fever.

Correct Answer: A

Rationale: In caring for an infant with congestive heart failure (CHF), modifying feeding techniques is crucial due to the child's weakness and fatigue. The correct answer, A) Feeding more frequently with smaller feedings, is appropriate because it helps prevent fatigue by providing adequate nutrition in smaller, more manageable quantities without overwhelming the infant's weakened cardiovascular system. Option B) Using a soft nipple with enlarged holes is incorrect because it may lead to rapid feeding, causing the infant to tire quickly and potentially exacerbate their CHF symptoms. Option C) Holding and cuddling the child during feeding, though important for emotional support, does not directly address the issue of modifying feeding techniques for weakness and fatigue. Option D) Substituting glucose water for formula is not recommended as it lacks essential nutrients needed for the infant's growth and development, which is especially crucial for a child with CHF. Educationally, understanding the rationale behind modifying feeding techniques in infants with CHF is vital for nurses caring for pediatric patients with complex cardiac conditions. It highlights the importance of individualized care to meet the specific needs of each child, ensuring optimal nutrition while managing their condition effectively. By selecting the appropriate feeding strategies, nurses can help improve outcomes and quality of life for infants with CHF.
