The nurse is performing an assessment on a child and notes the presence of Koplik’s spots. In which communicable disease are Koplik’s spots present?

This is because a patent ductus arteriosus is a congenital heart defect that involves a defect in which the fetal shunt between the aorta and the pulmonary artery fails to close. This causes a continuous machinery-like murmur that can be heard on auscultation.

Choice A is wrong because pulmonary stenosis is a narrowing of the pulmonary valve or artery that obstructs blood flow to the lungs. It causes a systolic ejection murmur that is best heard at the upper left sternal border.

Choice C is wrong because the ventricular septal defect is a hole in the wall between the ventricles that allows blood to flow from the left to the right side of the heart. It causes a loud, harsh holosystolic murmur that is best heard at the left lower sternal border.

Choice D is wrong because coarctation of the aorta is a narrowing of the aorta that reduces blood flow to the lower body. It causes a systolic murmur that radiates to the back and weak or absent femoral pulses.

The parents should notify the physician if the infant has a temperature above 37.7° C (100° F), new frequent coughing, or turning blue or bluer

than normal. These are signs of infection, respiratory distress, or cyanosis, which could indicate complications after cardiac surgery.

Choice A is wrong because a respiratory rate of 36 breaths/minute at rest is within the normal range for an infant.

Choice B is wrong because an appetite slowly increasing is a positive sign of recovery and does not require immediate attention.
