WCU Pathophysiology Midterm Questions with
Detailed Verified Answers
A patient is diagnosed with heart failure with normal ejection fraction. This patient is
most likely characterized by a(n) Ans: elderly woman without a previous history of MI.
In which dysrhythmias should treatment be instituted immediately? Ans: Atrial
fibrillation with a ventricular rate of 220 beats/minute
Aortic regurgitation is associated with Ans: diastolic murmur.
Mitral stenosis is associated with Ans: a pressure gradient across the mitral valve.
First-degree heart block is characterized by Ans: prolonged PR interval.
Which blood pressure reading is considered to be indicative of prehypertension
according to the JNC-7 criteria? Ans: 128/82
Increased preload of the cardiac chambers may lead to which patient symptom? Ans:
Edema
Beta-blockers are advocated in the management of heart failure because they Ans:
reduce cardiac output.
Hypotension associated with neurogenic and anaphylactic shock is because of Ans:
peripheral pooling of blood.
While hospitalized, an elderly patient with a history of myocardial infarction was noted
to have high levels of low-density lipoproteins (LDLs). What is the significance of this
finding? Ans: Increased LDL levels are associated with increased risk of coronary
artery disease.
Hypertension is closely linked to Ans: obstructive sleep apnea.
