A nurse cares for a client who is recovering from a myocardial infarction. The client states, I will need to stop eating so much chili to keep that indigestion pain from returning. How should the nurse respond?

Correct Answer: C

Rationale: In this scenario, option C, "What do you understand about what happened to you?" is the correct response. This option allows the nurse to assess the client's understanding of their condition, which is crucial for effective patient education and self-management. By asking this question, the nurse can evaluate the client's knowledge, correct any misconceptions, and provide tailored education to prevent future issues. Option A is incorrect because it does not address the client's understanding of their condition but rather focuses on the nutritional aspect of chili consumption. While diet modifications may be necessary, it is essential to first assess the client's knowledge and beliefs. Option B is incorrect as it assumes the client needs an antacid without assessing their understanding of the underlying cause of indigestion. Prescribing medication without proper evaluation and education could lead to dependence and mask potential issues. Option D is also incorrect as it focuses on the timing of the symptoms rather than the client's comprehension of their condition. Understanding the client's perception and knowledge is fundamental to providing effective care in pediatric nursing cardiovascular disorders. In clinical practice, effective communication and patient education are key components of nursing care. By assessing the client's understanding, nurses can tailor education to meet individual needs, promote adherence to treatment plans, and improve health outcomes.

Correct Answer: D

Rationale: The ductus arteriosus allows blood to flow from the higher-pressure aorta to the lower-pressure pulmonary artery, causing a right-to-left shunt. If this is surgically closed, no additional oxygenated blood (from the aorta) will return to the lungs through the pulmonary artery. The aorta carries oxygenated blood to the systemic circulation. Because of the higher pressure in the aorta, blood is shunted into the pulmonary artery and the pulmonary circulation. Edema in the legs and feet is usually a sign of heart failure. This repair would not directly affect the edema. Increasing the oxygenation of blood would not interfere with the return of oxygenated blood to the lungs.

Correct Answer: C

Rationale: In pediatric nursing, understanding the clinical manifestations of systemic venous congestion in heart failure is crucial for early recognition and intervention. The correct answer is C) Peripheral edema. This is because systemic venous congestion leads to fluid accumulation in the interstitial spaces, particularly in the dependent areas like the lower extremities, resulting in peripheral edema. Option A) Tachypnea is more indicative of respiratory distress, commonly seen in heart failure due to pulmonary congestion rather than systemic venous congestion. Option B) Tachycardia can be a compensatory mechanism to maintain cardiac output in heart failure but is not a direct result of systemic venous congestion. Option D) Pale, cool extremities are more characteristic of reduced peripheral perfusion, which can occur in more advanced or severe stages of heart failure rather than systemic venous congestion. Educationally, teaching students to differentiate between various clinical manifestations of heart failure helps in accurate assessment and timely management of pediatric patients. Recognizing peripheral edema as a sign of systemic venous congestion aids in providing appropriate care and preventing complications associated with heart failure in children.

Correct Answer: B

Rationale: In pediatric nursing, understanding the signs of digoxin toxicity is crucial as it is a common medication used in the management of cardiovascular disorders in children. The correct answer is B) Vomiting. Digoxin toxicity can present with gastrointestinal symptoms like vomiting, which can be an early indicator of an overdose. A) Seizures are not a common sign of digoxin toxicity in children. This symptom is more likely to be associated with other medication overdoses or conditions. C) Bradypnea (slow breathing) is not a typical sign of digoxin toxicity. In contrast, digoxin toxicity is more likely to manifest with respiratory distress or other cardiac-related symptoms. D) Tachycardia (rapid heartbeat) is actually a common therapeutic effect of digoxin rather than a sign of toxicity. In cases of digoxin toxicity, bradycardia (slow heartbeat) is more commonly observed due to the drug's effects on the heart's conduction system. Educationally, it is essential for nurses and parents to be aware of the signs and symptoms of digoxin toxicity to ensure early detection and prompt intervention. Teaching parents about these signs empowers them to monitor their child's condition closely and seek medical help if they notice any concerning symptoms, ultimately contributing to the safe management of their child's cardiovascular disorder.

Correct Answer: B

Rationale: In the context of caring for a child with persistent hypoxia due to a cardiac defect, preventing dehydration is crucial to decrease the risk of cerebrovascular accidents (strokes). Here's the detailed rationale: Preventing dehydration is essential because hypoxia places additional stress on the heart, potentially leading to decreased cardiac output and impaired circulation. Dehydration can further exacerbate these issues by reducing blood volume, which in turn increases the risk of clot formation and potential cerebrovascular accidents. Minimizing seizures (option A) is important in managing certain neurological conditions but is not directly related to reducing the risk of strokes in this scenario. Promoting cardiac output (option C) is a vital aspect of managing cardiovascular disorders, but dehydration directly impacts stroke risk and should be addressed first. Similarly, reducing energy expenditure (option D) may be important in conserving energy for a child with a cardiac defect, but it does not directly address the risk of strokes associated with dehydration. Educationally, understanding the interconnectedness of various physiological systems in pediatric patients with cardiac defects is crucial. Nurses must prioritize interventions based on the immediate risks to the child's health, such as preventing dehydration to reduce the risk of potentially life-threatening cerebrovascular accidents. This case highlights the importance of holistic care and the impact of fluid balance on cardiovascular health in pediatric patients.
