A nurse is assessing a child who has a ventricular septal defect. Which of the following findings should the nurse expect? A. Diastolic murmur B. Murmur at the left sternal border C. Cyanosis that increases with crying D. Widened pulse pressure

B. Murmur at the left sternal border A ventricular septal defect (a hole in the septal wall between the ventricles) is an acyanotic heart defect. A systolic murmur can be heard best at the lower left sternal border. The sound is transmitted in the direction of blood flow, so any backflow of blood from the left to the right ventricle through the septal defect is best heard in this area. Incorrect Answers: A. A diastolic murmur is an expected finding in a child who has an atrial septal defect. C. Cyanosis that increases with crying is an expected finding in a child who has an atrioventricular canal defect. D. Widened pulse pressure is an expected finding in a child who has patent ductus arteriosus.

A nurse is providing teaching to the guardian of a child who has Kawasaki disease. Which of the following statements by the guardian indicates an understanding of the teaching? (Select all that apply.) A. "My child will likely be irritable for the next few weeks." B. "I will notify my child's doctor if the skin on her hands or feet begins to peel." C. "I will ensure my child does not receive any live vaccines for at least 18 months." D. "I will keep a record of my child's temperature until she has no fever for several days." E. "My child will have joint stiffness primarily at the end of the day."

Correct Answers: A. "My child will likely be irritable for the next few weeks." C. "I will ensure my child does not receive any live vaccines for at least 18 months." D. "I will keep a record of my child's temperature until she has no fever for several days" - diagnosed with Kawasaki disease will likely be irritable for up to 2 months. - Kawasaki disease receives high doses of gamma globulin during the initial phase, which might result in the inability to produce adequate antibodies in response to a live vaccine; therefore, these vaccines should be delayed for 11 months. **temperature of this child who has Kawasaki disease should be recorded until she has been afebrile for several days. Incorrect Answers: B. Peeling of the skin of the hands and feet is expected for a child who has Kawasaki disease. The peeling does not cause any pain and usually occurs between the second and third week. There is no need to report this manifestation to the child's provider. E. A child who has Kawasaki disease will likely have joint stiffness and arthritis-related symptoms for several weeks. The joint stiffness is typically worse during cold weather and in the morning.

A nurse is caring for a child who has tetralogy of Fallot. Which of the following laboratory values should the nurse expect to find? A. Platelet count of 20,000/mm^3 B. WBC 4,000/mm^3 C. Thyroid stimulating hormone 7.0 microunts/mL D. RBC 6.8 million/uL

D. RBC 6.8 million/uL A child who has tetralogy of Fallot experiences cyanosis; therefore, the body responds by increasing RBC production (polycythemia) in an attempt to supply oxygen to all body parts. Incorrect Answers: A. A platelet count of 20,000/mm^3 is below the expected range. A child who has tetralogy of Fallot will not have a decreased platelet count. B. A WBC count of 4,000/mm^3 is below the expected reference range. A child who has tetralogy of Fallot will not have neutropenia. C. This hormone level is above the expected reference range. A child who has tetralogy of Fallot will not have changes in thyroid function levels.

A nurse is teaching the parents of a child who has rheumatic fever. Which of the following statements by a parent indicates an understanding of the teaching? A. "My child may take aspirin for his joint pain." B. "My child will need a blood transfusion prior to discharge." C. "I will need to wear a gown when I'm in my child's room." D. "I will apply lotion to my child's peeling hands."

A. "My child may take aspirin for his joint pain." Children who have rheumatic fever may take salicylates (aspirin) to control the inflammatory process that occurs in the joints. Incorrect Answers: B. A child who has rheumatic fever does not require blood transfusions since there is no blood loss from this disorder. C. A child who has rheumatic fever only needs standard isolation precautions. Rheumatic fever is an immune response that occurs after an infection with group Aß-hemolytic streptococci. D. Kawasaki disease causes peeling hands, but rheumatic fever does not.

An 18-month-old toddler who has Kawasaki disease (KD). The child is receiving intravenous immune globulin (IVIG). The guardian asks the nurse to administer the child's scheduled measles, mumps, and rubella (MMR) vaccine before discharge. Which of the following responses should the nurse provide? A. "Your child will not be able to receive the MMR vaccine for at least 3 months after discharge." B. "I cannot administer routine vaccines to children while they are in the hospital." C. "Your child can receive the MMR vaccine once his fever is gone." D. "I can administer the measles and rubella vaccines, but I cannot administer the mumps vaccine."

A. "Your child will not be able to receive the MMR vaccine for at least 3 months after discharge." The nurse should explain to the guardian that IVIG given for the treatment of KD contains antibodies that can interfere with the action of live-virus vaccines like MMR. The MMR immunization should be postponed for 3 to 6 months. Incorrect Answers: B. The toddler cannot receive the vaccine while in the hospital because the antibodies in the IVIG can interfere with the action of the MMR vaccine. However, hospitalization is not the reason for the immunization delay. C. The toddler will not be able to receive the MMR vaccine for a minimum of 3 months after completion of IVIG treatment, as the antibodies in the IVIG can interfere with the action of the MMR vaccine. D. These 3 vaccines are preferably given together as a single vaccine. The MMR vaccine contains live viruses, and the antibodies of the IVIG can interfere with the action of the vaccine.

A nurse is caring for a 4-month-old infant who has tetralogy of Fallot and experiences a hypercyanotic spell. Which of the following actions should the nurse take? A. Place the infant in knee-chest position • B. Begin CPR • C. Prepare to intubate the infant • D. Administer IV adenosine

A. Place the infant in knee-chest position The nurse should identify that a hypercyanotic spell occurs when a vascular spasm reduces pulmonary blood flow and forces blood to shunt from the right ventricle to the left ventricle through the ventricular septal defect. The nurse should place the infant in a knee-chest position to increase systemic vascular resistance, which will help force more blood through the pulmonary artery. Incorrect Answers: B. The nurse should identify that a hypercyanotic spell is a temporary period of hypoxia that can occur in response to crying, feeding, or straining during a bowel movement. The nurse should not initiate CPR because the infant is still breathing and has a pulse. C. The nurse should administer 100% oxygen via facemask to treat the hypoxia that occurs during a hypercyanotic spell. D. The nurse should not administer adenosine to an infant experiencing a hypercyanotic spell. Adenosine is an antiarrhythmic used in the treatment of supraventricular tachycardia.

A nurse is caring for a group of infants with congenital heart defects. For which of the following defects should the nurse expect to observe cyanosis? • A. Transposition of the great arteries • B. Ventricular septal defect • C. Coarctation of the aorta • D. Patent ductus arteriosus

A. Transposition of the great arteries An infant who has transposition of the great arteries will have severe cyanosis because reversal of the anatomical position of the aorta and pulmonary artery allows venous blood to enter the systemic circulation without oxygenation. Incorrect Answers: B. An infant who has a ventricular septal defect (a hole in the septal wall between the ventricles) can have increased pulmonary vascular resistance but is unlikely to have cyanosis because oxygenation of the blood remains adequate for systemic circulation. C. An infant who has coarctation of the aorta (constricted segment of the aorta that obstructs blood flow to the body) is unlikely to have cyanosis. Even though the left ventricle must generate higher than normal pressures for adequate stroke volume, oxygenation of the blood remains adequate for the systemic circulation. D. An infant who has a patent ductus arteriosus will have a blood vessel connecting the pulmonary artery to the aorta. The infant can have increased pulmonary vascular resistance, but oxygenation of the blood remains adequate for systemic circulation.

A nurse is assessing a 2-month-old infant who has a ventricular septal defect. Which of the following findings should the nurse report to the provider? A. Weight gain of 1.8 kg (4 lb) B. rate of 125/min C. Soft, flat fontanel D. Systemic murmur

A. Weight gain of 1.8 kg (4 lb) A 4 lb weight gain indicates increased fluid and worsening of the child's heart failure; therefore, the nurse should report this finding to the provider. Incorrect Answers: B. A heart rate of 125/min is an expected finding in a 2-month-old infant. C. A soft, flat fontanel is an expected finding in a 2-month-old infant. D. A systemic murmur is an expected finding in an infant who has a ventricular septal defect.

What teaching should parents of a child with Kawasaki Disease be given on its management?

Avoid contact sports for the child, limit strenuous activity, and monitor cardiac

A nurse is planning care for an infant who has heart failure. Which of the following interventions should the nurse include in the plan to meet the nutritional needs of the infant? (Select all that apply.) A. Offer the infant a feeding every 2 hr B. Allow 30 min to complete each feeding C. Gradually increase the caloric density of the formula D. Position the infant semi-upright during feedings E. Provide gavage feeding if respiratory rate exceeds 80/min

B. Allow 30 min to complete each feeding C. Gradually increase the caloric density of the formula D. Position the infant semi-upright during feedings E. Provide gavage feeding if respiratory rate exceeds 80/min The nurse should allow 30 minutes for each feeding. This length of feeding allows adequate intake without causing the infant to get overly fatigued or to lose needed rest time before the next feeding. The nurse should plan to provide the infant with a formula that has increased caloric density. An infant who has heart failure has an increased metabolic rate due to impaired cardiac function. Adding expressed breast milk or enteral nutrition formula or oil to the formula provides the infant with increased calories in a decreased volume of feeding. The nurse should gradually increase the caloric density of the feeding by 2 kcal/oz/day to promote infant tolerance and decrease the risk of diarrhea. The nurse should plan to hold the infant in a semi-upright position during feedings to promote maximum chest expansion and decrease the risk of respiratory distress. The nurse should plan to withhold oral feedings and provide gavage feedings if the infant shows indications of stress or fatigue. An infant who has a respiratory rate of 80/min to 100/min has tachypnea, which is an indicator of infant stress.

What is an important factor in pediatric heart history assessment?

How the baby feeds. Also color (ever turned blue), tiring/sweating/breathing fast or heavy, cough, weight gain or unable to gain weight, exercise intolerance in older children, syncope/dizziness, increased # of respiratory infection

What does it indicate if a child has turned blue?

Potential cyanosis.

What are diuretics commonly prescribed for?

Treating pulmonary and peripheral edema.
