A 5-year-old child with a ventricular septal defect (VSD) is scheduled for cardiac catheterization. The parents ask the nurse why this test is being done. While formulating a reply, what does the nurse recall is the function of the test?

Cardiac catheterization visualizes the exact location of the ventricular septal defect; also it measures pulmonary pressures. A murmur can be heard with a stethoscope placed at the left lower sternal border. Cardiomegaly and ventricular hypertrophy are both demonstrated on electrocardiography and echocardiography.

A 3-year-old child with the diagnosis of tetralogy of Fallot is brought to the United States by a charitable organization for cardiac surgery. What should the nurse expect when conducting an admission assessment of the child?

Hypoxia leads to poor peripheral circulation; clubbing occurs as a result of additional capillary development and tissue hypertrophy of the fingertips. A fever is not expected unless the child has an infection or is dehydrated; the data do not indicate this. The child's respiratory rate will be increased, not decreased. The child's problems are related to decreased oxygenation, not to a clotting deficiency.

arterial switch corrective for TGA aorta and pulmonary arteries are transected and reattached to the opposite stumps, coronary arteries are moved to a new aorta area

Jatene

A child with a congenital heart defect has a cardiac catheterization. What is an essential element of nursing care after this procedure?

Monitoring the extremity distal to the insertion site for changes in temperature and color should indicate the presence or absence of a clot; comparing pedal pulses of both extremities may reveal clot formation that disrupts circulation. The child is kept in bed at least 6 hours after the procedure. Fluids may be given as soon as tolerated. Pulses, not blood pressure, must be checked for quality and symmetry.

corrective for TGA when a VSD and severe PS is present the aortic root is translocated from the RV, w/ attached coronary vessels to the LV after reconstructing the L and R outflow tracts and patching the VSD

Nikaidoh

A child returns to his room after left-side cardiac catheterization. What is involved in the postprocedure nursing care?

Postprocedure hemorrhage, a life-threatening complication after cardiac catheterization, is possible because arterial blood is under pressure and the catheter has entered an artery. Rest will be encouraged; flexion of the insertion site should be avoided to prevent disturbance of the clot. Comparing blood pressures in the two extremities is unnecessary; the pulse distal to the catheterization insertion site is monitored. The blood pressure will not be unstable unless a problem develops; fluid intake should be encouraged.

S&S of nasopharyngitis

A nurse is caring for a child with a cardiac malformation associated with left-to-right shunting. What does the nurse consider the major characteristic of this type of congenital disorder?

With a left-to-right shunt, blood flows through a defect in the ventricular wall of the heart and is shunted from the higher pressure left side to the lower pressure right side. The increased blood flow from the right ventricle results in an increased blood flow to the lungs. Polycythemia and an increased hematocrit are not common in children with a left-to-right shunt. Severe growth retardation is not common in children with a left-to-right shunt. Clubbing is a more common finding in children with a right-to-left shunt.

What common finding can the nurse identify in most children with symptomatic cardiac malformations?

Children with cardiac malformations often require more energy to fulfill the activities of daily living; decreased oxygen utilization and increased energy output in the developing child result in a slow growth rate. Mental retardation is not a common finding in children with congenital heart disease. Cardiac anomalies are more often a result of prenatal, rather than genetic, factors. Clubbing is not characteristic of most children with cardiac anomalies, only of those with more severe hypoxia.

A nurse is reviewing the clinical records of infants and children with cardiac disorders in whom heart failure developed. What does the nurse identify as the last sign of heart failure?

Heart failure is characterized by a decrease in blood flow to the kidneys, causing sodium and water reabsorption and resulting in peripheral edema. The peripheral edema indicates severe cardiac decompensation. Tachypnea and tachycardia constitute an early attempt by the body to compensate for decreased cardiac output. Periorbital edema occurs most noticeably in children with acute poststreptococcal glomerulonephritis, not heart failure.

A 1-year-old child has a congenital cardiac malformation that causes right-to-left shunting of blood through the heart. What clinical finding should the nurse expect?

Polycythemia, reflected in an increased hematocrit reading, is a direct attempt by the body to compensate for the decrease in oxygen to all body cells caused by the mixture of oxygenated and deoxygenated circulating blood. Proteinuria is not a characteristic of heart malformations that cause right-to-left shunting of blood; nor is edema. An absence of pedal pulses is characteristic of coarctation of the aorta, an obstructive malformation.

A toddler undergoes cardiac catheterization as part of a diagnostic workup for pulmonic stenosis. In which part of the cardiovascular system should the nurse expect an increase in pressure?

Pulmonic stenosis increases resistance to blood flow, causing right ventricular hypertrophy; with right ventricular failure there is an increase in pressure on the right side of the heart. Pressure in the left side of the heart is decreased with pulmonic stenosis. Pressure in the pulmonary vein is decreased with pulmonic stenosis. Pressure in the pulmonary artery is decreased with pulmonic stenosis.

The nurse notes asystole on the cardiac monitor. Which action should the nurse take immediately?

Pulse should be immediately assessed because a lead or electrode coming off may mimic this dysrhythmia. Asystole is characterized by complete cessation of electrical activity. A flat baseline is seen, without any evidence of P, QRS, or T waveforms. A pulse is absent, and there is no cardiac output; cardiac arrest has occurred. Once confirmed, Basic Life Support (BLS) and Advanced Cardiovascular Life Support (ACLS) protocols are initiated for asystole. Defibrillation is part of the ACLS protocol for ventricular fibrillation.

A cardiac catheterization is performed on an infant. After the procedure, the leg used for the catheter insertion site becomes mottled. What is the best action by the nurse?

Some mottling is expected because of circulatory disruption and arterial spasm. Further assessment (e.g., palpation of the pedal pulse) is performed to rule out arterial occlusion. Elevation of the leg is contraindicated; elevation may induce bleeding from the puncture site. A blanket will interfere with inspection. Other observations should be made before the primary healthcare provider is notified.

A nurse teaches the parents of an infant with a cardiac defect how to detect impending heart failure. What should the parents be taught to identify as an early sign?

Tachycardia results from sympathetic stimulation in the setting of heart failure; it is the body's attempt to increase cardiac output and increase oxygen supply to the body's cells. The respirations will increase, not decrease, when heart failure occurs. Distended neck veins occur only in adults when heart failure has progressed to systemic congestion. Urinary output is decreased as a result of sodium and water retention.

A 3-month-old infant with tetralogy of Fallot is admitted for a diagnostic workup in preparation for corrective surgery. The morning after cardiac catheterization the infant suddenly becomes cyanotic and begins breathing rapidly. In what position should the nurse immediately place the infant?

The infant is experiencing a hypercyanotic ("tet" spell) episode caused by a sudden decrease in pulmonary blood flow and an increase in right-to-left shunting. It usually occurs after increased activity. The knee-chest position decreases venous return from the legs, which increases systemic vascular resistance, thereby increasing pulmonary blood flow. The supine and lateral positions increase venous return, which exacerbates the problem. Although the semi-Fowler position is recommended for infants with cardiac disease, it is not adequate for an infant experiencing a tet spell.

A child being treated with cardiac drugs developed vomiting, bradycardia, anorexia, and dysrhythmias. Which drug toxicity is responsible for these symptoms?

digoxin Digoxin helps improve pumping efficacy of the heart, but overdose can cause toxicity leading to nausea, vomiting, bradycardia, anorexia, and dysrhythmias. The side effects of nesiritide may include effects like headache, insomnia, and hypotension. Dobutamine does not cause nausea or vomiting but may cause hypertension and hypotension. Spironolactone may cause edema.

A client at 28 weeks' gestation with previously diagnosed mitral valve stenosis is being evaluated in the clinic. Which sign or symptom indicates that the client is experiencing cardiac difficulties?

syncope on exertion syncope on exertion is a definitive sign of cardiac decompensation; cardiac output is not meeting cellular oxygen needs. Systolic murmur may occur in a healthy pregnant woman because of the displacement of the heart, caused by the enlarging uterus that shifts the contents of the thoracic cavity and the increased blood volume and cardiac output. Heart palpitations and a displaced apical pulse both may occur in a healthy pregnant woman because of displacement of the heart caused by enlargement of the uterus that shifts the contents of the thoracic cavity, and the increased blood volume and cardiac output.

Based on the assessment of a full-term infant, the nurse suspects a cardiac anomaly. Which clinical manifestation does the nurse identify that indicates a cardiac anomaly?

A discrepancy in blood pressures from the arms to the legs indicates arterial stenosis caused by coarctation of the aorta. Projectile vomiting commonly results from pyloric stenosis; it is not of cardiac origin and does not occur immediately after birth. An irregular respiratory rhythm is common and expected in the healthy newborn. Hyperreflexia of the extremities may be indicative of a neurologic, not cardiac, problem.
