441. A child with rheumatic fever will be arriving in the nursing unit for admission. On admission assessment, the nurse should ask the parents which question to elicit assessment information specific to the development of rheumatic fever? 1."Has the child complained of back pain?" 2."Has the child complained of headaches?" 3."Has the child had any nausea or vomiting?" 4."Did the child have a sore throat or fever within the last 2 months?"

4. Rheumatic fever is an inflammatory autoimmune disease that affects the connective tissues of the heart, joints, skin (subcutaneous tissues), blood vessels, and central nervous system. Rheumatic fever characteristically manifests 2 to 6 weeks after an untreated or partially treated group A β-hemolytic streptococcal infection of the upper respiratory tract. Initially, the nurse determines whether the child had a sore throat or an unexplained fever within the past 2 months. Options 1, 2, and 3 are unrelated to rheumatic fever.

438. The nurse is closely monitoring the intake and output of an infant with heart failure who is receiving diuretic therapy. The nurse should use which most appropriate method to assess the urine output? 1.Weighing the diapers 2.Inserting a Foley catheter 3.Comparing intake with output 4.Measuring the amount of water added to formula

1. Heart failure is the inability of the heart to pump a sufficient amount of blood to meet the oxygen and metabolic needs of the body. The most appropriate method for assessing urine output in an infant receiving diuretic therapy is to weigh the diapers. Comparing intake with output would not provide an accurate measure of urine output. Measuring the amount of water added to formula is unrelated to the amount of output. Although Foley catheter drainage is most accurate in determining output, it is not the most appropriate method in an infant and places the infant at risk for infection.

440. The nurse has provided home care instructions to the parents of a child who is being discharged after cardiac surgery. Which statement made by the parents indicates a need for further instructions? 1."A balance of rest and exercise is important." 2."I can apply lotion or powder to the incision if it is itchy." 3."Activities in which my child could fall need to be avoided for 2 to 4 weeks." 4."Large crowds of people need to be avoided for at least 2 weeks after surgery."

2. The mother should be instructed that lotions and powders should not be applied to the incision site after cardiac surgery. Lotions and powders can irritate the surrounding skin, which could lead to skin breakdown and subsequent infection of the incision site. Options 1, 3, and 4 are accurate instructions regarding home care after cardiac surgery.

439. The clinic nurse reviews the record of a child just seen by a health care provider and diagnosed with suspected aortic stenosis. The nurse expects to note documentation of which clinical manifestation specifically found in this disorder? 1.Pallor 2.Hyperactivity 3.Exercise intolerance 4.Gastrointestinal disturbances

3. Aortic stenosis is a narrowing or stricture of the aortic valve, causing resistance to blood flow in the left ventricle, decreased cardiac output, left ventricular hypertrophy, and pulmonary vascular congestion. A child with aortic stenosis shows signs of exercise intolerance, chest pain, and dizziness when standing for long periods. Pallor may be noted, but is not specific to this type of disorder alone. Options 2 and 4 are not related to this disorder.

Assessment findings of an infant admitted to the hospital reveal a machinery-like murmur on auscultation of the heart and signs of heart failure. The nurse reviews congenital cardiac anomalies and identifies the infant's condition as which disorder? Refer to figure (the circled area) to determine the condition. 1.Aortic stenosis 2.Atrial septal defect 3.Patent ductus arteriosus 4.Ventricular septal defect

3. A patent ductus arteriosus is failure of the fetal ductus arteriosus (artery connecting the aorta and the pulmonary artery) to close. A characteristic machinery-like murmur is present, and the infant may show signs of heart failure. Aortic stenosis is a narrowing or stricture of the aortic valve. Atrial septal defect is an abnormal opening between the atria. Ventricular septal defect is an abnormal opening between the right and left ventricles.

434. The nurse is monitoring an infant with congenital heart disease closely for signs of heart failure (HF). The nurse should assess the infant for which early sign of HF? 1.Pallor 2.Cough 3.Tachycardia 4.Slow and shallow breathing

3. Heart failure (HF) is the inability of the heart to pump a sufficient amount of blood to meet the oxygen and metabolic needs of the body. The early signs of HF include tachycardia, tachypnea, profuse scalp sweating, fatigue and irritability, sudden weight gain, and respiratory distress. A cough may occur in HF as a result of mucosal swelling and irritation, but is not an early sign. Pallor may be noted in an infant with HF, but is not an early sign.

436. On assessment of a child admitted with a diagnosis of acute-stage Kawasaki disease, the nurse expects to note which clinical manifestation of the acute stage of the disease? 1.Cracked lips 2.Normal appearance 3.Conjunctival hyperemia 4.Desquamation of the skin

3. Kawasaki disease, also known as mucocutaneous lymph node syndrome, is an acute systemic inflammatory illness. In the acute stage, the child has a fever, conjunctival hyperemia, red throat, swollen hands, rash, and enlargement of the cervical lymph nodes. In the subacute stage, cracking lips and fissures, desquamation of the skin on the tips of the fingers and toes, joint pain, cardiac manifestations, and thrombocytosis occur. In the convalescent stage, the child appears normal, but signs of inflammation may be present.

437. The nurse provides home care instructions to the parents of a child with heart failure regarding the procedure for administration of digoxin (Lanoxin). Which statement made by the parent indicates the need for further instruction? 1."I will not mix the medication with food." 2."I will take my child's pulse before administering the medication." 3."If more than one dose is missed, I will call the health care provider." 4."If my child vomits after medication administration, I will repeat the dose."

4. Digoxin is a cardiac glycoside. The parents need to be instructed that if the child vomits after digoxin is administered, they are not to repeat the dose. Options 1, 2, and 3 are accurate instructions regarding the administration of this medication. In addition, the parents should be instructed that if a dose is missed and is not identified until 4 hours later, the dose should not be administered.

435. The nurse reviews the laboratory results for a child with a suspected diagnosis of rheumatic fever, knowing that which laboratory study would assist in confirming the diagnosis? 1.Immunoglobulin 2.Red blood cell count 3.White blood cell count 4.Anti-streptolysin O titer

4. Rheumatic fever is an inflammatory autoimmune disease that affects the connective tissues of the heart, joints, skin (subcutaneous tissues), blood vessels, and central nervous system. A diagnosis of rheumatic fever is confirmed by the presence of two major manifestations or one major and two minor manifestations from the Jones criteria. In addition, evidence of a recent streptococcal infection is confirmed by a positive anti-streptolysin O titer, Streptozyme assay, or anti-DNase B assay. Options 1, 2, and 3 would not help to confirm the diagnosis of rheumatic fever.

442. A health care provider has prescribed oxygen as needed for an infant with heart failure. In which situation should the nurse administer the oxygen to the infant? 1.During sleep 2.When changing the infant's diapers 3.When the mother is holding the infant 4.When drawing blood for electrolyte level testing

4. Heart failure (HF) is the inability of the heart to pump a sufficient amount of blood to meet the oxygen and metabolic needs of the body. Crying exhausts the limited energy supply, increases the workload of the heart, and increases the oxygen demands. Oxygen administration may be prescribed for stressful periods, especially during bouts of crying or invasive procedures. Options 1, 2, and 3 are not likely to produce crying in the infant.
