The nurse is taking a health history of a 6-week-old boy with a suspected cardiovascular disorder. Which response by the mother would lead the nurse to suspect that the child is experiencing heart failure?

"He gets sweaty when he eats." Explanation: Diaphoresis with nipple feeding indicates heart failure. Shortness of breath would suggest heart failure. Children with heart failure experience subtle signs that suggest that something is wrong. Children with heart failure often display subtle signs such as difficulty feeding.

An infant with poor feeding is suspected of having a congenital heart defect. The parents are asking why a chest x-ray is necessary in their infant. What is the best response from the nurse?

"It will determine if the heart is enlarged." Explanation: Chest x-rays= are performed to see if the heart is enlarged. This will determine if the heart muscle is increasing in size. EKG= Disturbances in heart conduction are detected by an EKG. Echocardiogram= Visualizing where blood is being shunted is through the echocardiogram. MRI= The image used to clarify the structures of the heart is the MRI.

The parents of a 5-year-old child with a cardiovascular disorder tell the nurse they don't understand why their child isn't gaining weight, "We make sure our child has 3 very nutritious meals every day." How should the nurse respond?

"It's great you are providing nutritious meals, but smaller frequent meals will tire your child less and promote weight gain." Explanation: Small, frequent feedings will reduce the amount of energy required to feed or eat and prevents overtiring the child. Questioning if the parents are making nutritious foods or foods the child likes does not address the issue of energy expenditure when eating 3 larger meals per day. Just stating that it is "hard to get your child to eat enough" also does not address the situation.

A child will be undergoing a Holter monitor test. Which statement by the mother indicates the need for further instruction?

"My child cannot have any thing to eat or drink after midnight the day of the test." Explanation: Ambulatory electrocardiographic monitoring (Holter) testing is an exam that spans approximately 24 hours. The test is done to review the activity of the heart. The individual is encouraged to follow their normal activities during the test. There is no need for the child to be NPO prior to or during the test.

The nurse is caring for a 7-year-old who is being discharged following surgery with a Gore® Helex device to repair an atrial septal defect. The parents of the child demonstrate understanding of the procedure with which statements? Select all that apply.

"We will be sure to not allow our child to ride a bicycle for at least 2 weeks." "We will be sure to monitor our child for any signs of infection and notify the doctor if we notice any." "We know how important our child's medications are so we will write out a schedule to be sure medications are taken as prescribed."

The nurse is caring for an infant with Down syndrome who has been diagnosed with atrioventricular canal defect. The parents ask the nurse, "Why do you not put oxygen on our baby more often when his lips and fingernails are blue?" What is the best response by the nurse?

"While it seems that oxygen would help, it actually worsens this condition. Treating the cause of the disease will help." Explanation: For children with congenital defects with increased pulmonary blood flow, oxygen supplementation is not helpful. Oxygen acts as a pulmonary vasodilator. If pulmonary dilation occurs, pulmonary blood flow is even greater, causing tachypnea, increasing lung fluid retention, and eventually causing a much greater problem with oxygenation; therefore, preventing the development of pulmonary disease via early surgical correction is essential. Although oxygen must be ordered by the physician and it isn't the best treatment, the nurse stating, "While it seems that oxygen would help, it actually makes the condition worse. Treating the cause of the disease will help" best answers the question while also showing empathy.

A nurse is examining a 10-year-old girl who has a heart murmur. On auscultation, the nurse finds that the murmur occurs only during systole, is short, and sounds soft and musical. When she has the girl stand, she can no longer hear the murmur on auscultation. Which statement should the nurse make to the girl's mother in response to these findings?

"Your daughter has an innocent heart murmur, which is nothing to worry about." Explanation: The symptoms described indicate an innocent heart murmur. Although innocent murmurs are of no consequence, parents need to be told when their child has one because this finding will undoubtedly be discovered again at a future health assessment or during a febrile illness, anxiety, or pregnancy. Activities need not be restricted when a child has an innocent murmur and the child requires no more frequent health appraisals than other children. If a murmur is present as the result of heart disease or a congenital disorder, it is an organic heart murmur. Reference:

A nurse is preparing to administer a prescribed dose of digoxin to an 6-month-old infant. After assessing the infant's apical pulse, the nurse decides to withhold the dose and notify the health care provider. The nurse bases this decision on which apical pulse rate?

80 beats/min Explanation: Prior to administering each dose of digoxin, the nurse would count the apical pulse for 1 full minute, noting rate, rhythm, and quality. The nurse would withhold the dose and notify the health care if the apical pulse is less than 60 in an adolescent, less than 90 in an infant.

Which nursing diagnosis would best apply to a child with rheumatic fever?

Activity intolerance related to inability of heart to sustain extra workload Explanation: Acute rheumatic fever affects the joints, central nervous system, skin, and soft tissue. It causes chronic, progressive damage to the heart and valves. Children with rheumatic fever need to reduce activity to relieve stress on the heart and joints during the course of the illness. Rheumatic fever does not produce cardiomegaly nor does it interfere with respirations or the ability to oxygenate the body. Children with rheumatic fever may develop chorea. These movements are involuntary and are not related to hyperexcitability.

A child is diagnosed with rheumatic fever. For which medication will the nurse educate the caregivers?

Aspirin Explanation: Medications used in the treatment of rheumatic fever include penicillin, salicylates (aspirin), and corticosteroids. Insulin would be given for diabetes and dilantin for seizure disorders. Antivirals are not relevant to the treatment of a bacterial infection.

Coarctation of the aorta demonstrates few symptoms in newborns. What is an important assessment to make on all newborns to help reveal this condition?

Assessing for the presence of femoral pulses **As a result, the blood pressure will be higher in the upper part of the body and decreased in the lower part of the body.** Explanation: Coarctation of the aorta is a defect where there is narrowing of the aorta, which is the largest vessel carrying oxygenated blood to the body. As a result of this narrowing, blood flow is impeded causing pressure to increase in the area proximal to the defect and decrease distal to the defect. As a result, the blood pressure will be higher in the upper part of the body and decreased in the lower part of the body. The pulses will be full or bounding in the upper part of the body and weak or absent in the lower part of the body. When assessing an infant with coarctation there may be weak or absent femoral pulses. There will also be differences in the blood pressure readings. These infants may or may not have a murmur and will be no more fussy than other babies.

A 5-year-old is being prepared for diagnostic cardiac catheterization, in which the catheter will be inserted in the right femoral vein. What intervention should the nurse take to prevent infection?

Avoid drawing a blood specimen from the right femoral vein before the procedure Explanation: Because the vessel site chosen for catheterization must not be infected at the time of catheterization (or obscured by a hematoma), never draw blood specimens from the projected catheterization entry site before the procedure (generally a femoral vein). The other interventions listed are performed for reasons other than prevention of infection. Children scheduled for the procedure are usually kept NPO for 2 to 4 hours beforehand to reduce the danger of vomiting and aspiration during the procedure. Be certain to record pedal pulses for a baseline assessment. The site for catheter insertion is locally anesthetized with EMLA cream or intradermal lidocaine.

What information would be included in the care plan of an infant in heart failure

Begin formulas with increased calories. Infants with heart failure need increased calories for growth. The infants are typically given smaller, more frequent feedings to decrease the amount given and to help conserve energy for feeding. They often are given a higher-calorie formula. The infant should be placed in an upright position or in a car seat to increase oxygenation. The infant should not have any pressure on the diaphragm while in this position. Vomiting is a sign of digoxin toxicity and this should be considered before administering.

The nurse is reviewing the laboratory test results of several children who have come to the clinic for evaluation. Which child would the nurse identify as having the least risk for hyperlipidemia?

Child A with a total cholesterol of 150 mg/dl and low-density lipoprotein (LDL) of 80 mg/dl. Explanation: ACCEPTABLE RANGE= Total cholesterol levels below 170 mg/dl and LDL levels less than 100 mg/dl are considered within the acceptable range. BORDERLINE= Total cholesterol levels between 170 and 199 mg/dl and LDL levels between 100 and 129 mg/dl are considered borderline. GREAT RISK= Total cholesterol levels greater than or equal to 200 mg/dl and LDL levels greater than or equal to 130 mg/dl are considered elevated and place this child at greatest risk.

The nurse is assessing the heart rate of a 6-month-old infant and determines it to be 82 beats/min. What action should the nurse take first?

Conduct a focused cardiovascular assessment. Explanation: The normal infant heart rate averages 90 to 160 beats/min. This infant's heart rate is low. The nurse should first conduct a focused cardiovascular assessment. After that is completed, the findings can be reported to the health care provider. Obtaining a health history can be beneficial, but with a low heart rate the nurse would want to know first if there are any other clinical signs indicating a problem or a reason for the heart rate. The heart rate should be reassessed, but not necessarily in a 5-minute window. The heart rate should be assessed via apical pulse for a full 60 seconds.

The nurse is administering medications to the child with congestive heart failure (CHF). Large doses of what medication are used initially in the treatment of CHF to attain a therapeutic level?

Digoxin Explanation: The use of large doses of digoxin at the beginning of therapy to build up the blood levels of the drug to a therapeutic level is known as digitalization. During the 24 hours digitalization is occurring, the child should be on a cardiac monitor and the nurse should monitor the PR interval and a decreased ventricular rate. The other listed medications are not administered in this manner. Albuterol is inhaled for asthma treatment and used primarily for exacerbations. Ferrous sulfate is give for iron-deficiency anemia, and spironolactone is a diuretic.

A nurse admits an infant with a possible diagnosis of congestive heart failure. Which signs or symptoms would the infant most likely be exhibiting?

Feeding problems The indications of CHF vary in children of different ages. Signs in the infant may be hard to detect because they are subtle, but in infants, feeding problems are often seen. In infants and older children, tachycardia is one of the first signs of CHF. In a child with CHF, tachypnea would be seen, not bradypnea. The heart beats faster in an attempt to increase blood flow. Failure to gain weight, weakness, and an enlarged liver and heart are other possible indicators of CHF but are not as common as tachycardia and may take longer to develop.

The nurse performs a cardiac assessment and notes a loud heart murmur with a precordial thrill. This murmur would be classified as a:

Grade IV: Explaination: Grade I= is soft and hard to hear. Grade II= is soft and easily heard. Grade III= is loud without thrill Grade IV= A heart murmur characterized as loud with a precordial thrill is classified as Grade IV.

The nurse in a pediatric cardiovascular clinic is talking with the father of a 5-year-old child who underwent cardiac surgery for a heart defect at the age of 3. The father reports that the child has been having increased shortness of breath, tires easily after playing, and has been gaining weight. The nurse is aware that the child is most likely demonstrating symptoms of which acquired cardiovascular disorder?

Heart failure Explanation: Infective endocarditis = would present with intermittent, unexplained low-grade fever, fatigue, anorexia, weight loss, or flu-like symptoms. cardiomyopathy= include respiratory distress, fatigue, poor growth (dilated), chest pain, dizziness, and syncope. Kawasaki Disease= Abdominal pain, joint pain, fever, irritability

On assessment immediately following cardiac surgery, which condition would the nurse expect to find in an infant?

Hypothermia Cardiac surgery is often performed under hypothermia to decrease the child's oxygen needs during surgery. The postoperative care nurse should assess the infant's vital signs continuously via monitoring. The temperature should be assessed at least once per hour until an optimal temperature is achieved. The infant would have received IV fluids during surgery so hypovolemia should not be the primary concern. The infant will be sleepy from anesthesia, not hyperexcited. Hypertension, if any, has been monitored throughout the surgery and controlled.

The nurse is educating an adolescent female at risk for hypertension. Which interventions will the nurse recommend? Select all that apply.

Increase hours of sleep. Avoid any smoking. Exercise on a daily basis. Maintain a healthy weight.

An 8-month-old infant has a ventricular septal defect. Which nursing diagnosis would best apply?

Ineffective tissue perfusion related to inefficiency of the heart as a pump Explanation: A ventricular septal defect permits blood to flow across an opening between the right and left ventricles. It results in increased pulmonary blood flow, but it does not cause cyanosis. The blood in the left ventricle, which flows back into the right ventricle, is already oxygenated. Anytime there is an opening between the heart's ventricles, the heart is not as effective as a pump because the pressure gradients are changed. A ventricular septal defect will not cause respiratory problems or problems with peripheral circulation.

A 6-year-old girl is diagnosed with pulmonary stenosis. The mother asks the nurse what the likely treatment for this condition will involve. What should the nurse tell the mother?

Insertion of a catheter with an uninflated balloon tip into the affected valve, followed by inflation of the balloon to break up adhesions Explanation: Balloon angioplasty by way of cardiac catheterization is the procedure of choice for pulmonary stenosis. With this procedure, a catheter with an uninflated balloon at its tip is inserted and passed through the heart into the stenosed valve. As the balloon is inflated, it breaks valve adhesions and relieves the stenosis. The other answers refer to interventions related to patent ductus arteriosus, not pulmonary stenosis.

A nurse is assessing the skin of a 12-year-old with suspected right ventricular heart failure. Where should the nurse expect to note edema in this child?

Lower extremities Explanation: Edema of the lower extremities is characteristic of right ventricular heart failure in older children. In infants, peripheral edema occurs first in the face, then the presacral region, and the extremities.

The nurse is auscultating heart sounds of a child with a mitral valve prolapse. The nurse should expect which assessment finding?

Mild to late ejection click at the apex Explanation: A mild to late ejection click at the apex is typical of a mitral valve prolapse. Abnormal splitting or intensifying of S2 sounds occurs in children with heart problems, not mitral valve prolapse. Clicks on the upper left sternal border are related to the pulmonary area.

A nurse is caring for a child with Kawasaki disease. Which assessment finding would the nurse expect to see?

Peeling hands and feet; fever Explanation: Kawasaki disease is an acute systemic vasculitis. Symptoms begin with very high fevers. One of the signs of Kawasaki disease is the peeling hands and feet and in perineal region. The child is usually tachycardic and laboratory values would indicate increased platelets and decreased hemoglobin. Another classic sign of Kawasaki is the strawberry tongue. The other symptoms are not necessarily characteristic of Kawasaki disease. The child should be evaluated if there are impalpable pulses because this could indicate a heart defect or some other serious illness.

The nurse is caring for a 6-year-old with a congenital heart defect. To best relieve a hypercyanotic spell, what action would be the priority?

Place the child in a knee-to-chest position. Explanation: The priority nursing action is to place the infant or child in a knee-to-chest position. Once the child has been placed in this position, the nurse should provide supplemental oxygen or administer medication as ordered. A calm, comforting approach should be used but is not the priority action. Once a child is placed in the knee-to-chest position, supplemental oxygen would be provided as ordered.

An infant with tetralogy of Fallot becomes cyanotic. Which nursing intervention would be the first priority?

Place the infant in the knee-chest position. Explanation: Placing the infant in the knee-chest position is the first priority when caring for an infant with tetralogy of Fallot. Starting IV fluids and preparing the child for surgery would not be necessary since it is known that the infant has a cyanotic birth defect. Raising the head of the bed would not be a priority since the infant needs to be placed in the knee-chest position.

When reviewing the record of a child with tetralogy of Fallot, what would the nurse expect to discover?

Polycythemia Explanation: Tetralogy of Fallot= is a congenital heart defect causing decreased pulmonary blood flow. This causes mild to severe oxygen desaturation. To compensate for the low blood oxygenation the kidneys produce erythropoietin to stimulate the bone marrow to make more red blood cells (RBCs). The increased amount of RBCs is known as polycythemia. This increased blood volume causes more workload on the heart. It also does not increase the amount of blood reaching the lungs so the child remains desaturated. Leukopenia, increased platelets, and anemia are not associated with tetralogy of Fallot.

Which collaborative actions will the nurse perform when caring for an infant with transposition of the great arteries scheduled for surgical repair of the defect? Select all that apply.

Provide education to the parents. Auscultate lung sounds frequently. Apply a continuous pulse oximeter. Keep oxygen saturation above 75%. Explanation: Collaborative interventions for an infant with transposition of the great arteries include providing education to parents in preparation for their infant's surgery; assessing pulse oximetry and auscultating lung sounds frequently to monitor for signs of increased pulmonary flow; and maintaining normal oxygen saturation for transposition of the great arteries at 75% to 85%. Administering indomethacin would cause closure of the ductus arteriosus, which would prevent mixing of blood.

A parent brings an infant in for poor feeding and listlessness. Which assessment data would most likely indicate a coarctation of the aorta?

Pulses weaker in lower extremities compared to upper extremities Explanation: With coarctation of the aorta there is a narrowing causing the blood flow to be impeded. This produces increased pressure in the areas proximal to the narrowing and a decrease in pressures distal to the narrowing. Thus, the infant would have decreased systemic circulation. The upper half of the body would have an increased B/P and be well perfused with strong pulses. The lower half of the body would have decreased B/P with poorer perfusion and weaker pulses. Coarctation is not a cyanotic defect. The cyanosis would be associated with tetralogy of Fallot.

Which nursing diagnosis will the nurse indicate as priority for the child following cardiac surgery for tetralogy of Fallot?

Risk for ineffective cardiopulmonary tissue perfusion Explanation: Nursing priority following cardiac surgery will focus on assessing for ineffective cardiopulmonary tissue perfusion. Monitoring for excess fluid volume, infection, and anxiety will be monitored after ensuring cardiopulmonary tissue perfusion is adequate.

A child with a cardiac structural defect is receiving oxygen therapy. In which position should the child be placed to promote optimal benefits?

Semi-Fowler Explanation: Due to the hemodynamic changes accompanying the underlying structural defect, oxygenation is key. Provide frequent ongoing assessment of the child's cardiopulmonary status. Assess airway patency and suction as needed. Position the child in the Fowler or semi-Fowler position to facilitate lung expansion.

A child with heart disease is receiving digoxin and a diuretic. Which laboratory test result would be most important for the nurse to monitor?

Serum potassium level Explanation: Children receiving diuretics should have serum potassium levels obtained because diuretics tend to deplete the body of potassium. This is even more important if the child is also receiving digoxin because low serum potassium levels potentiate or increase the effect of the drug. Serum sodium levels may be obtained in children with heart failure to ensure that an increased sodium level is not causing edema. The erythrocyte sedimentation rate identifies inflammation and is unrelated to the use of diuretics and digoxin. Oxygen saturation levels may be done to evaluate for hypoxemia, but these results would be unrelated to the use of digoxin and diuretics.

The nurse is teaching an in-service program to a group of nurses on the topic of children diagnosed with rheumatic fever. The nurses in the group make the following statements. Which statement is most accurate regarding the diagnosis of rheumatic fever?

Strep throat Rheumatic fever is precipitated by a streptococcal infection, such as strep throat, tonsillitis, scarlet fever, or pharyngitis, which may be undiagnosed or untreated. Rheumatic fever is a chronic disease of childhood, affecting the connective tissue of the heart, joints, lungs, and brain. There is no immunization to prevent rheumatic fever. The onset of rheumatic fever is often slow and subtle.

When caring for a child with a congenital heart defect, which assessment finding may be a sign the child is experiencing heart failure?

Tachycardia Why? Lets See... eart failure occurs when the heart has the inability to pump effectively to provide adequate blood, oxygen, and nutrients to the body's organs and tissues. Symptoms occur because of three factors. The neurohormonal influences cause symptoms of tachycardia, pallor, decreased urine output, sweating, hypertension, weight gain and edema. The symptoms seen from systolic dysfunction are dyspnea on exertion, increased work of breathing, and feeding difficulties. Diastolic influences produce hepatomegaly, jugular vein distention and periorbital edema.

A newborn has been diagnosed with a congenital heart disease. Which congenital heart disease is associated with cyanosis?

Tetralogy of Fallot Explanation: Tetralogy of Fallot is associated with cyanosis. The defects include ventricular septal defect (VSD), right ventricular hypertrophy, right outflow obstruction, and overriding aorta. Coarctation of aorta, pulmonary stenosis, and aortic stenosis are acyanotic heart diseases and are not associated with cyanosis.

When examining a child with congenital heart disease, an organ in the upper right quadrant of the abdomen can be palpated at 4 cm below the rib cage. What would most likely explain this assessment finding?

The liver size increases in right-sided heart failure. Explanation: The liver increases in size due to right-sided heart failure. This is one of the cardinal signs of congestive heart failure. The spleen is in the upper left quadrant of the abdomen and would increase in size under certain circumstances, but this is asking for the upper right quadrant information. There are certain medications that can affect the liver, but this would not be the most likely reason for hepatomegaly.

A nurse is interviewing a mother who is about to give birth. Which response would alert the nurse for a higher potential for a heart defect in the newborn?

The mother states she has lupus. Explanation: A health history should be obtained from the pregnant woman. This history should include having problems during birth of any previous children, frequent infections, chromosomal abnormalities, having a premature birth, having an autoimmune disease or taking long-term medications such as corticosteroids. Lupus= while pregnant could contribute to a congenital heart defect. Acetaminophen & sleeping= do not affect the newborn's potential for developing a heart defect. The seizure medication= can have an impact on the newborn having a heart defect, but not necessarily a history of seizures in the mother. A seizure in the mother would be more related to hypoxia in the newborn than a heart defect.

A nurse is caring for an infant who just had open-heart surgery and the parents are asking why there are wires coming out of the infant's chest. What is the best response by the nurse?

These wires are connected to the heart and will detect if your infant's heart gets out of rhythm. Following cardiac repair there is always a possibility of arrhythmias. The wires are placed and connected to an external pacemaker. This is done as a preventive measure and can be used if an arrhythmia occurs. Once it is felt the child is in no danger of an arrhythmia, the wires are removed. There is no set time period in which this occurs. The wires do not deliver ongoing electrical shocks to maintain rhythm. This would be done by a permanent pacemaker implanted under the skin. There is no measurement of fluid in the heart by wires. Any measurements would need to be performed by echocardiogram or cardiac catheterization.

A mother is asking for more information about her infant's patent ductus arteriosus (PDA). What would be included in the education?

This is caused by an opening that usually closes by 1 week of age. Explanation: A PDA is caused by an opening called the ductus arteriosus. A PDA usually closes by 1 week of age. If it does not close, the defect is usually fixed by a single surgery or during a cardiac catheterization procedure. IV fluids are not a routine intervention for the PDA. Most of the time a PDA occurs in premature infants.

A child with a congenital heart defect is getting an echocardiogram. How would the nurse describe this test to the parent?

This test will check how blood is flowing through the heart. Explanation: An echocardiogram (echo)= is a noninvasive ultrasound used to assess the heart wall thickness, the size of the heart chambers, the motion of the valves and septa, and the relationship of the great vessels to other cardiac structures. The test evaluates how blood is flowing through the heart and how effective the heart is in pumping. An echo does not check the electrical impulses. This would be done with an electrocardiogram.

A group of students are reviewing information about acute rheumatic fever. The students demonstrate a need for additional review when they identify what as a major Jones criterion?

arthralgia Arthralgia is considered a minor criterion. Carditis is a major criterion. Erythema marginatum is considered a major criterion. Subcutaneous nodules are considered a major criterion.

When a child is scheduled for a cardiac catheterization, an important health teaching point for parents is that the:

child will return with a bulky pressure dressing over the catheter insertion area. Explanation: Cardiac catheterization is typically performed with the child awake but using moderate sedation. Only under unusual circumstances will the child need general anesthesia. At the completion of the procedure a pressure dressing will be placed over the catheter insertion site. This is to prevent bleeding. The nurse will monitor this dressing every 15 minutes for the first hour and then every 30 minutes for the second hour. A cardiac catheterization is an invasive procedure and any procedure is frightening to children, especially if their parents are not with them. After the child is fully awake from the procedure the diet can resume.

After assessing a child, the nurse suspects coarctation of the aorta based on a finding of:

femoral pulse weaker than brachial pulse. Explanation: A femoral pulse that is weak or absent in comparison to the brachial pulse is associated with coarctation of the aorta. Bounding pulse is characteristic of patent ductus arteriosus or aortic regurgitation. A narrow or thread pulse is associated with heart failure or severe aortic stenosis. Hepatomegaly is a sign of right-sided heart failure.

The nurse is providing education to parents of a child with a blood pressure in the 90th percentile. What would be included in the intervention strategies?

he nurse would review the child's 24-hour diet recall. Explanation: With a child in the 90th percentile for blood pressure, diet and physical activity should be the main focus. Blood pressures should be measured but daily measurement is not necessary. Children are not routinely put on beta-blockers, and the child should be allowed to participate in sports if monitored.

The health care provider suspects an infant may have a ventricular septal defect. The parents ask the nurse what diagnostic tests the infant will need to have to determine this diagnosis. For what test(s) should the nurse provide education to the family? Select all that apply.

magnetic resonance imaging (MRI) echocardiogram cardiac catheterization A ventricular septal defect (VSD) is an abnormal opening between the right and left ventricles. MRI or echocardiogram with color-flow Doppler may reveal the opening as well as the extent of left-to-right shunting. These studies also may identify right ventricular hypertrophy and dilation of the pulmonary artery resulting from the increased blood flow. Cardiac catheterization may be used to evaluate the extent of blood flow being pumped to the pulmonary circulation and to evaluate hemodynamic pressures. Neither a CT nor stress test are used in the diagnosis of the VSD. A chest x-ray may also be used to determine if there is enlargement of the heart.

What would be the most important measure to implement for an infant who develops heart failure?

placing the infant in a semi-Fowler position Semi-Fowlers= Placing an infant with heart failure in a semi-Fowler position reduces the pressure of the abdominal contents against the chest and allows for better lung expansion. Supine= Keeping the infant supine would cause more pressure on the heart and lungs and increase the work of the heart and lungs Calories intake= Infants with heart disease need calories to grow. They are given formula or breast milk which is fortified with extra nutrients. Thus the infant can have an intake of the same amount of fluid but receive extra nutrients.
