Coronary artery perfusion is dependent upon: A. Diastolic pressure B. Systolic pressure C. Afterload D. SVR A. Diastolic pressure Rationale: Diastolic pressure in the aortic root is higher than left ventricular end diastolic pressure (LVEDP) (the pressure exerted on the ventricular muscle at the end of diastole when the ventricle is full). This enables blood to flow from a higher pressure through open arteries to a lower pressure. This pressure gradient is known as coronary artery perfusi...

During the 48 hours after a myocardial infarction (MI), a nurse should assign the highest priority to monitoring the patient for what complication? Dysrhythmias Anxiety and fear Metabolic acidosis Medication side effects - Answer Dysrhythmias The nurse must be most alert for dysrhythmias, which may signal another MI or impending complications. The nurse should also be alert for increased anxiety, which may cause pain and lead to a secondary infarction. Anxiety and fear are...

AACN CSC (CSC) Practice Test 2023-2024 Questions & Answers. Graded A+ You are caring for a patient with an intra-aortic balloon pump and note blood in the tubing. Your initial action should be: A. Stop the balloon pump and notify the physician. B. Administer 100% oxygen to help displace the helium and notify the physician C. Leave the IABP running and notify the physician. D. Purge the IABP manually to clear the blood from the tubing. A. Blood in the IABP tubing indicates a balloon rupture ...

platelet -platelet plug (white clot) is effective for small injuries -ordinarily, platelets do not react with endothelium; BUT in the presence of injury, platelets become activated and actually change shape and appearance CORRECT ANSWER-the smallest of blood cells, made in bone marrow; 200 billion produced per day, greater than 1 trillion circulating at all times; white, live 7-10 days activated platelets--> secrete ADP--> activation of COX pathway--> phospholipase 2 mediated-->...

CMC AACN EXAM 2024 WITH COMPLETE SOLUTIONS While caring for a patient with an IABP at 3:1, the nurse notes: A. decreasing urine output as well as increasing BUN and CR levels; the nurse should increase timing to 2:1 B. absent pulses in the proximal extremity; the nurse should apply pressure at the insertion site. C. blood in the IABP tubing; the nurse should disconnect the balloon catheter from the IABP. D. blood oozing from the insertion site; the nurse should anticipate the need for a...

The nurse is caring for a patient who is receiving IV furosemide and morphine for the treatment of acute decompensated heart failure (ADHF) with severe orthopnea. Which clinical finding is the best indicator that the treatment has been effective? a. Weight loss of 2 lb in 24 hours b. Hourly urine output greater than 60 mL c. Reduced dyspnea with the head of bed at 30 degrees d. Patient denies experiencing chest pain or chest pressure - Reduced dyspnea with the head of bed at 30 degrees W...

Cardiac PCCN Test questions and answers already passed Coronary artery perfusion is dependent upon: A. Diastolic pressure B. Systolic pressure C. Afterload D. SVR A. Diastolic pressure Rationale: Diastolic pressure in the aortic root is higher than left ventricular end diastolic pressure (LVEDP) (the pressure exerted on the ventricular muscle at the end of diastole when the ventricle is full). This enables blood to flow from a higher pressure through open arteries to a lower pre...
