You can determine a pulse deficit by counting the: Apical and radial pulses at the same time, then finding the difference between the two Apical pulse first, then the radial pulse, and subtracting to find the difference between the two Apical pulse and the femoral pulse at the same time and finding the difference between the two Radial pulse first, then counting the femoral pulse, and subtracting to find the difference between the two Apical and radial pulses at the same time, then findin...

-95% of cases are essential hypertension -Secondary cause workup: renal disease, renal stenosis, aortic coarctation, hyperaldosteronism from tumor or hyperplasia, Cushing’s, pheochromocytoma, OSA -May hear S4 from forceful atrial contraction 03 Apex, S4, LLD, B3 JNC- 7 classifications and initial treatment of HTN -Pre-HTN is 120/80 to 139/89  lifestyle changes -HTN stage I is 140/90 to 159/99  thiazide (or loop if renal pt) -HTN stage II is >160/>100  thiazide + 2nd ...

Surgery EOR Exam [PAEA Blueprint] Questions with 100% correct answers _______is the most important anesthetic complication. Anesthesia causes an uncontrolled increase in skeletal muscle oxidative metabolism, which overwhelms the body's capacity to supply oxygen, remove CO2, and regulative body temperature. ANS-Malignant hyperthermia If patient is hyperkalemic (normal range 3.8-5.0), how should you treat the patient? ANS-treat with glucose/insulin, and calcium +/-bicarb _______is the reve...

EKG correct answers records the electrical activity of the heart and can identify an abnormal cardiac rhythm and sometimes cardiac muscle damage Stress test correct answers Monitors cardiac activity while exercising or after medications are given to increase the heart rate. it detect whether there is a change in rhythm or signs of cardiac ischemia echocardiogram correct answers an ultrasound of the heart to evaluate contractility and valve function. Can be done through the chest wall or tr...
