An 18-month-old with a myelomeningocele is undergoing a cardiac catheterization. The mother expresses concern about the use of dye in the procedure. The child does not have any allergies. In addition to an iodine allergy, which other allergy should the nurse bring to the attention of the catheterization staff?

Correct Answer: B

Rationale: In this scenario, the correct answer is B) Latex. The rationale for this lies in the fact that children with myelomeningocele, a neural tube defect, are at increased risk for latex allergy. Latex is commonly found in medical equipment, including catheters, and exposure can lead to allergic reactions ranging from mild irritation to severe anaphylaxis. Option A) Soy, Option C) Penicillin, and Option D) Dairy are incorrect choices in this context. While allergies to these substances are possible in pediatric patients, they are not specifically associated with myelomeningocele or cardiac catheterization procedures. Educationally, it is crucial for nurses caring for pediatric patients with myelomeningocele to be aware of the increased risk of latex allergy and take appropriate precautions to prevent exposure. This knowledge ensures the safety and well-being of the child during invasive procedures like cardiac catheterization. Additionally, understanding the specific risks and considerations for this patient population enhances the nurse's ability to provide high-quality, individualized care.

Correct Answer: B

Rationale: In this scenario, the correct answer is B) Lipid profile. The rationale behind this recommendation is to assess the child's risk factors for cardiovascular disorders due to family history. A lipid profile measures the levels of cholesterol and triglycerides in the blood, which are important indicators of cardiovascular health. Children with a family history of premature cardiovascular disease are at higher risk, and early detection through lipid profiling can help in implementing preventive measures such as lifestyle modifications and potential pharmacological interventions. Option A) Electrocardiogram (ECG) is not the most appropriate choice in this situation because it primarily provides information about the electrical activity of the heart. While an ECG can be useful in specific cardiac conditions, it is not the primary screening tool for assessing cardiovascular risk in a child with a family history of myocardial infarction. Option C) Echocardiogram is a diagnostic tool that uses sound waves to create images of the heart structure and function. While echocardiography is valuable in evaluating congenital heart defects or specific cardiac abnormalities, it is not typically indicated as an initial screening test in this context. Option D) Cardiac catheterization is an invasive procedure used to diagnose and treat certain heart conditions by inserting a catheter into the heart's blood vessels. It is an aggressive approach that is not warranted as a routine screening test for a toddler with a family history of myocardial infarction. In an educational context, understanding the rationale behind choosing the appropriate diagnostic tests based on clinical scenarios is crucial for nurses and healthcare professionals. It helps in developing critical thinking skills and evidence-based practice, ensuring that patient care is individualized and effective. By grasping the significance of early risk assessment and preventive strategies in pediatric cardiovascular health, nurses can contribute to promoting long-term well-being in children at risk.

Correct Answer: B

Rationale: The correct answer is B) Your baby's defect is small and will likely close on its own by 1 year of age. This response is the best because it reflects the current understanding of ventricular septal defects (VSDs) in pediatric patients. In infants, small VSDs often close spontaneously as the child grows, reducing the need for surgical intervention. This information is crucial for parents to understand to alleviate unnecessary anxiety and concern about their baby's condition. Option A) It is always helpful to get a second opinion about any serious condition like this. While seeking a second opinion is generally a good practice in medical decision-making, in this case, it may not address the specific nature of VSDs in infants and could potentially lead to unnecessary procedures or interventions. Option C) It is common for physicians to wait until an infant develops respiratory distress before they do the surgery. This statement is incorrect as waiting for the development of respiratory distress in an infant with a small VSD is not a recommended approach. Surgical intervention is typically not the first-line treatment for small VSDs in infants. Option D) With a small defect like this, they wait until the child is 10 years old to do the surgery. This option is incorrect as it provides misinformation about the appropriate timing for surgical intervention in cases of small VSDs in infants. Waiting until the child is 10 years old for surgery is not aligned with current medical guidelines for managing VSDs in pediatric patients. Educational Context: Educating parents about the natural course of VSDs in infants is essential for promoting informed decision-making and reducing unnecessary anxiety. Providing accurate information about the expected outcomes and management strategies for small VSDs helps parents feel empowered and involved in their child's care. It is crucial for nurses to have a solid understanding of pediatric cardiovascular disorders like VSDs to effectively communicate with parents and support them in navigating their child's healthcare journey.

Correct Answer: C

Rationale: In the context of pediatric cardiovascular disorders like congestive heart failure (CHF), adherence to treatment is crucial for optimal management. Option C, 50th percentile height and weight for age, indicates that the parent is following the prescribed treatment. Children with CHF may have poor growth due to the condition, so achieving the 50th percentile suggests that the treatment is effective in supporting growth and development. Option A, a heart rate of 56 beats per minute, may not necessarily indicate treatment adherence as it could be within the normal range for a 7-year-old. Elevated red blood cell count (Option B) may be a sign of chronic hypoxia, which is common in CHF, but it does not directly indicate treatment adherence. Option D, urine output of 0.5 cc/kg/hr, is important in assessing kidney function in CHF, but it does not specifically reflect treatment compliance by the parent. Educationally, understanding these assessment parameters helps nurses and healthcare providers evaluate treatment effectiveness in pediatric patients with CHF. Monitoring growth parameters like height and weight can provide valuable insights into the overall management of the condition and guide treatment adjustments if needed.

Correct Answer: A

Rationale: In congestive heart failure (CHF), hypoxemia occurs due to inadequate oxygen delivery to tissues. This triggers compensatory mechanisms, such as increased erythropoietin production, leading to polycythemia (option A). Polycythemia is the body's response to hypoxemia, aiming to increase oxygen-carrying capacity. Clubbing may also develop due to chronic hypoxemia. Option B, anemia and barrel chest, are not typical physiological changes seen in response to hypoxemia in CHF. Anemia is more commonly associated with conditions like chronic kidney disease or nutritional deficiencies. Barrel chest is a physical finding seen in conditions like chronic obstructive pulmonary disease (COPD) due to air trapping. Option C, increased white blood cells and low platelets, are not direct consequences of hypoxemia in CHF. Elevated white blood cells may indicate infection or inflammation, while low platelets can occur in conditions like immune thrombocytopenia. Option D, elevated erythrocyte sedimentation rate and peripheral edema, are not specific changes related to hypoxemia in CHF. Elevated erythrocyte sedimentation rate is a nonspecific marker of inflammation, while peripheral edema is more commonly associated with fluid retention in CHF. Understanding the physiological responses to hypoxemia in CHF is crucial for nurses caring for pediatric patients with cardiovascular disorders. Recognizing these changes helps in early identification of complications and appropriate management to optimize patient outcomes.
