APEA EXAM CARDIO

Question 1: The lymphatic ducts drain into the: arterial system. venous system. Correct arteriovenous system. capillary bed. Incorrect Explanation: The lymphatic ducts drain into the venous system. Question 2: While auscultating the patient's heart, a medium, soft murmur is audible. It is pansystolic and heard loudest at the apex with radiation to the left axilla. These findings are consistent with: tricuspid regurgitation.mitral regurgitation. Correcta ventricular septal defect.an innocent murmur. Incorrect Explanation: Mitral regurgitation produces a pansystolic, harsh murmur heard loudest at the apex with radiation toward the left axilla. The intensity of the murmur can be soft or if there is an atrial thrill, it can be loud. With tricuspid regurgitation, the murmur is audible loudest at the left sternal border with radiation to the right sternal border, xiphoid area, or to the left midclavicular line. It produces a blowing sound and is pansystolic. The murmur of an uncomplicated ventricular septal defect has a high pitch and is usually heard throughout systole. An innocent murmur is heard loudest at mid systole near the second to fourth intercostal spaces between the left sternal border and the apex. It usually decreases or disappears when sitting. Question 3: Which of the following group of symptoms would be suggestive of an infant experiencing a congenital heart defect associated with a decreased pulmonary blood flow pattern? Tissue perfusion greater than 3 seconds, bluish colored skin, and poor feeding Correct Abnormal heart sounds, capillary refill less than 2 seconds, and oxygen saturation less than 95% Capillary refill less than 2 seconds, tissue perfusion less than 3 seconds, and oxygen saturation greater than 95% Poor feeding, audible heart murmur, and oxygen saturation greater than 95%
