Perfusion Exam Questions And Answers With Detailed Solutions 2024

Perfusion Exam Questions And Answers With Detailed Solutions 2024 Your patient is having a cardiac catheterization. What pulses do you want to assess before and after the procedure? - correct answer.If the cath. is going through the arm, you are going to want to assess the ulnar and radial pulses before and after. If the cath. is going through the leg, you are going to want to assess the femoral and the dorsal pedis, maybe even the posterial tibial. Your patient will need an arterial line. What assessment will you want to do? - correct answer.You would do an Allen test before the art. line insertion, and after you will want to assess the patient's distal neurovascular areas. Your patient is having a left total hip. What pulse assessments will you want to do pre and post op? - correct answer.Femoral and posterior tibial What is a pulse deficit? How do you assess for it? - correct answer.When your apical pulse is different from your radial pulse. You take the apical pulse and the radial pulse, if they are both different, then there's a pulse deficit. What is a pulse pressure? What does it mean? - correct answer.Systolic-Diastolic=PP. This represents the force the heart generates each time it contracts. What is orthostatic hypotension? What can cause it? - correct answer.A drop in blood pressure due to a sudden change of posture. It can be caused by taking antihypertensive medications, rapid fluid changes, beta-blockers, vasodilators, and several other medications. Normal Central Venous Pressure (CVP) - correct answer.2-6 mmHg Troponin test - correct answer.Proteins released when the heart muscle has been damaged. Should be less than 0.2 mcg/L CK-MB - correct answer.Creatine Kinase-Muscle Breakdown. High --> heart damage; Normal is less than 6% Myoglobin (Mb) - correct answer.Found in the blood when an injury occurs. Brain Natriuretic Peptide (BNP) - correct answer.<100 pg/mL; Produced by ventricular muscles in response to increased preload, which caused increased ventricular pressure. Abnormal results often correlate with a diagnosis of heart failure. A result of greater than 100 pg/mL is suggestive of heart failure. C-reactive protein (CRP) - correct answer.Blood test used to measure the level of inflammation in the body; may indicate conditions that lead to cardiovascular disease. Inflammation plays a role in the development and progression of atherosclerosis. It is also used to assess the likelihood of CVD. A person with a result of less than 1 mg has a low likelihood and a person with a result of greater than 3mg/L has a high likelihood. Homocysteine - correct answer.An amino acid that is linked to the development of atherosclerosis because it can damage the endothelial lining of arteries and promote thrombus formation. Chest X-Ray - correct answer.It is used to assess the size, contour, and position of the heart. It can also identify cardiac and peripheral calcifications. Cannot diagnose an acute MI. Electrocardiogram (ECG) - correct answer.Recording of the electrical changes that occur in the myocardium during a cardiac cycle. The 12-lead ECG is used to diagnose dysrhythmias, conduction abnormalities, and chamber enlargement, as well as myocardial ischemia, injury, or infarction. It can also suggest cardiac effects of electrolyte disturbances (high or low calcium and potassium levels) and the effects of antiarrhythmic medications. Exercise Stress Test - correct answer.A method of testing the ability of the heart to respond to stress by having the patient perform a carefully controlled amount of exercise. The test is finished when the achieved heart rate is met, or if the patient develops S/S of myocardial ischemia. Pharmacologic Stress Test - correct answer.Cardiovascular stress induced by meds when routine stress test is contraindicated or if patient is unable to complete the exercise stress test. Vasodilating drugs like Adenosine are used to mimic the effects of by maximally dilating the normal coronary arteries. It can last 1-3 hours. Echocardiogram - correct answer.Ultrasound of the heart; used to indicate wall motion abnormalities; good for visualizing valves or chambers; often done as outpatient or after patient is admitted; pericardial effusion. It can be
