Barron's CCRN Cardiac questions with correct answers

The nurse is caring for a patient with acute inferior wall MI, post-coronary artery stent deployment. For optimal care of the patient, the nurse should: a) administer an analgesic for acute back pain b) Apply pressure dressing to groin c) Continuously monitor the patient in lead II d) Maintain the patient in a supine position CORRECT ANSWER Answer: C It is best practice to continuously monitor the patient status post PCI with stent, in the lead that was most abnormal during the acute occlusion. Lead II would most likely meet this criterion for the patient with an inferior wall MI. The remaining interventions are NOT indicated for the patient post PCI. The patient with aortic regurgitation will have which of the following on auscultation? a) Diastolic murmur, loudest at the 5th intercostal space, midclavicular b) Systolic murmur, loudest at the apex of the heart c) Diastolic murmur, loudest at the second intercostal space, right sternal border d) Systolic murmur, loudest at the base of the heart CORRECT ANSWER Answer: C Aortic insufficiency (regurgitation) is backflow of blood during the time the aortic valve should be closed. When is the aortic valve closed? During diastole — therefore it is a diastolic murmur. The aortic area of auscultation is at the base of the heart, second intercostal spac
