엔���렉스 NCLEX 아동(Child Health) 전범위 정리본

Atrial septal defect (ASD); 심실중격결손
; an abnormal opening between the right and left atria(좌우 심실 사이 비정상적 개구), allowing blood from the higher pressure left atrium to flow into the lower pressure right atrium(더 높은 압력의 좌심방=>더 낮은 압력의 우심방)***.
; 비청색증형 acyanotic congenital heart defects; ∵blood flows from the high-pressure left side (oxygenated blood) to the low-pressure right side. (산소화된 좌측->우측으로 흐름)

*s/s; hear a murmur. ; The flow of blood between the two chambers causes a vibration that is heard as a murmur  on auscultation.  ASD has a characteristic systolic murmur with a second heart sound(쾅) that is split(쪼개다).  Some clients may also have a diastolic murmur. 
#오답:Cyanosis(청색증형); Tetralogy of Fallot and hypoplastic left heart syndrome(좌심형성부전증후군).
#오답: Muffled(약한,덮인) heart tones: that are heard after surgical intervention are concerning for cardiac tamponade.
#오답: Weak lower and strong upper extremity pulses; are present in coarctation of the aorta(대동맥협착), not in ASD.
