| Term | Definition |
|---|---|
| What procedure uses high-frequency sound waves obtained by a transducer to produce an image of cardiac structures? | Echocardiography uses high-frequency sound waves. The child must lie completely still. |
| After a patient returns from cardiac catheterization, the nurse notes that the pulse distal to the catheter insertion site is weaker (+1). The most appropriate nursing intervention is to | document the findings and continue to monitor.The pulse distal to the catheter insertion site may be weaker for the first few hours after catheterization. It should gradually increase in strength. The extremity is kept straight and immobile |
| Surgical repair for patent ductus arteriosus (PDA) is done to prevent the complication of | D. Correct increased pulmonary vascular congestion. A PDA allows blood to flow from the aorta (high pressure) to the pulmonary artery (low pressure). If the PDA stays open, increased pulmonary vascular congestion can occur. |
| A PDA involves a | left-to-right shunt of blood. |
| What is considered a mixed cardiac defect? | D. Correct Transposition of the great arteries Transposition of the great arteries allows the mixing of both oxygenated and unoxygenated blood in the heart |
| Pulmonic stenosis is classified as | an obstructive defect. |
| Patent ductus arteriosus is classified as . | a defect with increased pulmonary blood flow |
| Atrial septal defect is classified as | a defect with increased pulmonary blood flow. |
| What is an early sign of congestive heart failure that the nurse should recognize? | A. Correct Tachypnea Tachypnea is one of the early signs of congestive heart failure that should be identified. Tachycardia at rest, dyspnea, retractions, and activity intolerance are other physical signs and symptoms. |
| The nurse is preparing to give digoxin (Lanoxin) to a 9-month-old infant. The nurse checks the dose; 4 mL of the drug is to be drawn up. the most appropriate action by the nurse is | A. Correct do not draw-up dose; suspect dosage error. Digoxin is often prescribed in micrograms. Rarely is more than 1 mL administered to an infant. |
| What is an important nursing responsibility when a dysrhythmia is suspected? | Correct Count the apical pulse for 1 full minute, and compare the rate with the radial pulse rate. This is the nurse's first action. If a dysrhythmia is occurring, the radial pulse rate may be lower than the apical pulse rate. |
| The primary therapy for secondary hypertension in children is | D. Correct treatment of underlying cause. |
| What should the nurse recognize as an early clinical sign of compensated shock in a child? | D. Correct Apprehensiveness Apprehensiveness is indicative of compensated shock. |
| Confusion is indicative of | uncompensated shock. |
| Hypotension is a symptom of | irreversible shock. |
| diagnosis of rheumatic fever is being ruled out for a child. Which lab test(s) is/are the most reliable? | C.CorrectAntistreptolysin-O titer (ASO) titer The most reliable and best standardized lab for antistreptococcal antibodies is an Antistreptolysin-O (ASO) titer |
