WCU PATHO 370 CHYU. WEEK 3 EXAM
2026/2027 | BRAND NEW ACTUAL EXAM
QUESTIONS WITH VERIFIED ANSWERS
A patient with pure left-sided heart failure is likely to exhibit
a. jugular vein distention.
b. pulmonary congestion with dyspnea.
c. peripheral edema.
d. hepatomegaly. - correct-answer-Pulmonary congestion with dyspnea
A middle-aged patient has a follow up visit for a recorded blood pressure of
162/96 mm Hg taken 3 weeks ago. The patient has nosignificant past medical
history and takes no medications, but smokes 1 1/2 packs of cigarettes per day,
drinks alcohol regularly,and exercises infrequently. The patient is about 40 lbs.
overweight and admits to a high-fat, high-calorie diet. At the office visittoday, the
patient's blood pressure is 150/92 mm Hg. What is the least appropriate
intervention for this patient at this time?
º Begin lifestyle modifications.
º Begin antihypertensive drug therapy.
º Recheck blood pressure in 4 to 6 weeks.
, Page |2
º Encourage smoking cessation. - correct-answer-Begin antihypertensive drug
therapy
ºAntihypertensive drug therapy is not the first intervention in a person with
modifiable risk factors.
Primary treatment for myocardial infarction (MI) is directed at
º protecting the heart from further ischemia.
º decreasing myocardial oxygen demands.
º reducing heart rate and blood pressure.
º activating the parasympathetic system. - correct-answer-Decreasing myocardial
oxygen demands
ºReducing oxygen demand may be effective in preserving myocardial muscle.
Once the cardiac muscle has been damaged, it is more important to preserve
remaining muscle and prevent further loss of the myocardium
A patient who reports dizziness and who has absent P waves, wide QRS
complexes, and a heart rate of 38 beats/minute on an ECG is most likely in which
rhythm?
º Ventricular escape rhythm
, Page |3
º Sinus bradycardia
º Third-degree heart block
º Junctional tachycardia - correct-answer-Ventricular escape rhythm
ºA ventricular escape rhythm originates in the Purkinje fibers, has a rate of 15 to
40 beats/minute, and is characterized by a wide QRS complex.
The majority of tachydysrhythmias are believed to occur because of
º triggered activity.
º enhanced automaticity.
º defective gap junctions.
º reentry mechanisms. - correct-answer-Reentry mechanisms
ºReentry is a complex process in which a cardiac impulse continues to depolarize
in a part of the heart after the main impulse has finished its path.
The prevalence of high blood pressure is higher in
º Non-Hispanic white adults.
º Mexican-American adults.
