Pediatric Cardiovascular Nursing Questions Questions
Question 1 of 5
In which of the following valve lesions, Dimensionless Index (DI) is used as an echocardiographic parameter to assess the severity of the lesion?
Correct Answer: A
Rationale: The correct answer is A) Aortic stenosis. The Dimensionless Index (DI) is used as an echocardiographic parameter to assess the severity of aortic stenosis. DI is calculated by dividing the LVET (left ventricular ejection time) by the LVET + VET (valve ejection time). In aortic stenosis, DI helps in determining the degree of obstruction in the aortic valve and the pressure gradient across the valve. Option B) Aortic regurgitation is incorrect because DI is not typically used to assess the severity of aortic regurgitation. In aortic regurgitation, parameters like regurgitant volume and regurgitant fraction are more commonly utilized. Option C) Mitral regurgitation is incorrect because DI is not a standard parameter for evaluating the severity of mitral regurgitation. Parameters such as regurgitant volume, regurgitant fraction, and EROA (effective regurgitant orifice area) are more commonly employed. Option D) Mitral stenosis is incorrect as DI is not a commonly used parameter to assess the severity of mitral stenosis. In mitral stenosis, parameters like mitral valve area, mean diastolic pressure gradient, and pulmonary artery pressure are usually considered. Understanding the appropriate echocardiographic parameters for different valve lesions is crucial in pediatric cardiovascular nursing. It helps in accurately assessing the severity of the valve lesion, guiding treatment decisions, and monitoring the effectiveness of interventions. Mastering these concepts is essential for providing quality care to pediatric patients with cardiovascular conditions.
Question 2 of 5
The parent of a 1-year-old child with tetralogy of Fallot asks the nurse, “Why do my child’s fingertips look like that?” On what understanding does the nurse base a response?
Correct Answer: D
Rationale: In this scenario, the correct answer is D) Clubbing occurs as a result of chronic hypoxia. Clubbing refers to the bulbous enlargement of the fingertips and nails due to chronic hypoxia. In tetralogy of Fallot, there is a right-to-left shunting of blood, leading to decreased oxygenation of the blood. This chronic hypoxia triggers a series of physiological responses, one of which is clubbing. Option A) Clubbing does not occur due to untreated congestive heart failure in this case, but rather due to chronic hypoxia. Option B) Clubbing is not a result of left-to-right shunting of blood, but rather right-to-left shunting in tetralogy of Fallot. Option C) While clubbing can be associated with decreased cardiac output, in this case, it is primarily due to chronic hypoxia. Educationally, understanding the association between clubbing and chronic hypoxia in pediatric cardiovascular conditions like tetralogy of Fallot is crucial for nurses caring for these patients. Recognizing clubbing can prompt further investigation and appropriate interventions to address the underlying hypoxia, thereby improving patient outcomes.
Question 3 of 5
A client with a productive cough has obtained a sputum specimen for culture as instructed. What is the best initial nursing action?
Correct Answer: B
Rationale: In the context of pediatric cardiovascular nursing and pharmacology, it is essential to prioritize evidence-based nursing actions to ensure optimal patient outcomes. In this scenario, the best initial nursing action is option B: Observe the color, consistency, and amount of sputum. This choice is correct because it allows the nurse to gather crucial information about the sputum, which can provide insights into the type of infection present and guide appropriate treatment. Option A, administering the first dose of antibiotic therapy, is incorrect as it is crucial to wait for the results of the sputum culture before starting specific antibiotic treatment to ensure targeted therapy. Jumping to antibiotic administration without proper assessment can lead to inappropriate treatment and potential resistance. Option C, encouraging the client to consume warm liquids, is not the priority at this stage. While hydration is important, assessing the sputum takes precedence to determine the underlying cause of the cough. Option D, sending the specimen to the lab for analysis, is a necessary step but not the initial action. First, a visual assessment of the sputum can provide immediate information that may influence the decision to send the specimen and guide the laboratory analysis effectively. Educationally, this question highlights the importance of thorough assessment and evidence-based practice in pediatric nursing. It emphasizes the significance of data collection before initiating treatment interventions, especially in scenarios involving infectious processes where tailored therapy is crucial for positive patient outcomes.
Question 4 of 5
A client with a history of asthma and bronchitis arrives at the clinic with shortness of breath, productive cough with thickened tenacious mucous, and the inability to walk up a flight of stairs without experiencing breathlessness. Which action is most important for the nurse to instruct the client about self-care?
Correct Answer: A
Rationale: The correct answer is A) Increase the daily intake of oral fluids to liquefy secretions. In a client with asthma and bronchitis presenting with shortness of breath and thickened mucous, increasing oral fluid intake helps to thin out the mucus, making it easier to expel. This self-care measure can improve breathing and decrease the feeling of breathlessness. Option B) Avoid crowded enclosed areas to reduce pathogen exposure is incorrect as it does not directly address the client's current symptoms of shortness of breath and thickened mucous. While reducing exposure to pathogens is important for respiratory health, it is not the most immediate intervention needed in this case. Option C) Call the clinic if undesirable side effects of medications occur is also incorrect as the client's current symptoms are related to the thickened mucous and breathlessness, not necessarily medication side effects. This option does not address the client's immediate needs. Option D) Teach anxiety reduction methods for feelings of suffocation is incorrect as the client's symptoms are primarily due to the physical manifestations of asthma and bronchitis, rather than anxiety. While anxiety may exacerbate symptoms, addressing it alone will not directly improve the client's breathing difficulty and thickened mucous. In an educational context, it is essential for nurses to understand the rationale behind self-care instructions for clients with respiratory conditions. Teaching clients about the importance of increasing oral fluid intake can empower them to take an active role in managing their symptoms and improving their quality of life. By explaining the physiological reasons behind this recommendation, nurses can help clients make informed decisions about their self-care practices.
Question 5 of 5
A client with cholelithiasis has a gallstone lodged in the common bile duct and is unable to eat or drink without becoming nauseated and vomiting. Which finding should the nurse report to the healthcare provider.
Correct Answer: C
Rationale: In this scenario, the correct answer is C) Yellow sclera. Yellow sclera is indicative of jaundice, a common manifestation of common bile duct obstruction. When the common bile duct is obstructed by a gallstone, bilirubin cannot be excreted properly, leading to jaundice. This finding is significant as it suggests a worsening condition that requires prompt medical attention to prevent further complications. Belching (option A) and flatulence (option D) are common gastrointestinal symptoms that may occur due to various reasons, including dietary factors or digestive issues. These symptoms, while uncomfortable, are not specific indicators of a common bile duct obstruction in this context. Amber urine (option B) can be a normal finding and may indicate dehydration rather than a direct consequence of the common bile duct obstruction. It is not a primary concern in this situation where the focus should be on identifying signs of worsening obstruction. In an educational context, understanding the clinical manifestations of common bile duct obstruction in patients with cholelithiasis is crucial for nurses caring for such patients. Recognizing these signs early can help in timely intervention and prevention of complications. Nurses must be able to prioritize and report significant findings to healthcare providers promptly to ensure appropriate management and patient safety.
