WCU Patho 370 CHYU: Week 3
A patient has a history of falls, syncope, dizziness, and blurred vision. The patient's symptomology is most likely related to
º hypertension.º hypotension.º deep vein thrombosis.º angina (Ans- Hypotension
An example of an acyanotic heart defect is
º tetralogy of Fallot.º transposition of the great arteries.º ventricular septal defect.º all right-to-left shunt defects.(Ans- Ventricular septal defect
º In this condition, blood from the left ventricle leaks into the right ventricle because of a defect in the ventricular wall. This leakage causes extra pressure in the right ventricle resulting in pulmonary hypertension.
Cor pulmonale refers to
º bi-ventricular failure.º left ventricular hypertrophy secondary to lung disease.º right ventricular hypertrophy secondary to pulmonary hypertension.º right ventricular failure secondary to right ventricular infarction.(Ans- Right ventricular hypertrophy secondary to pulmonary hypertension
Low cardiac output to the kidneys stimulates the release of _____ from juxtaglomerular cells.
- / 2
º aldosterone º norepinephrine º angiotensinogen º renin (Ans- Renin
Which blood pressure reading is considered to be indicative of prehypertension according to the JNC-7 criteria?
º 118/78
º 128/82
º 140/88
º 138/94
(Ans- 128/82
In which dysrhythmias should treatment be instituted immediately?
º Asymptomatic sinus bradycardia at a heart rate of 50 beats/minute º Fever-induced tachycardia at 122 beats/minute º Premature atrial complexes occurring every 20 seconds º Atrial fibrillation with a ventricular rate of 220 beats/minute (Ans- Atrial fibrillation with a ventricular rate of 220 beats/minute
ºIt allows blood to become stagnant in the atria and may lead to formation of thrombi. This condition requires resuscitation because of the reduction in cardiac output
Which finding is indicative of orthostatic hypotension in a person with a supine blood pressure (BP) of 110/70 and a heart rate(HR) of 100?
º Sitting BP 88/60, HR 118 º Sitting BP 108/68, HR 102 º Sitting BP 110/78, HR 98 º Sitting BP 120/80, HR 100 (Ans- Sitting BP 88/60, HR 118
