1. Which condition is a cause of acquired aortic regurgitation?
a. Congenital malformation
b. Rheumatic fever
c. Cardiac failure
d. Coronary artery disease (CAD) –

Correct Answer :Rheumatic fever. Rheumatic heart disease, bacterial endocarditis, syphilis, hypertension,
connective tissue disorders (e.g., Marfan syndrome, ankylosing spondylitis), appetite suppressing medications,
trauma, or atherosclerosis can cause acquired aortic regurgitation.
1. Which predominantly female valvular disorder is thought to have an autosomal dominant inheritance pattern,
as well as being associated with connective tissue disease?
a. Mitral valve prolapse
b. Tricuspid valve prolapse
c. Tricuspid stenosis
d. Aortic insufficiency –
Correct Answer :Mitral valve prolapse. Mitral valve prolapse tends to be most prevalent in young women.
Studies suggest an autosomal dominant and X-linked inheritance pattern. Because mitral valve prolapse often is
associated with other inherited connective tissue disorders (e.g., Marfan syndrome, Ehlers-Danlos syndrome,
osteogenesis imperfecta), it is thought to result from a genetic or environmental disruption of valvular
development during the fifth or sixth week of gestation.
1. A patient is diagnosed with pulmonary disease and elevated pulmonary vascular resistance. Which form of
heart failure may result from pulmonary disease and elevated pulmonary vascular resistance?
a. Right heart failure
b. Low-output failure
c. Left heart failure
d. High-output failure –
Correct Answer :Right heart failure. Right heart failure is defined as the inability of the right ventricle to provide
adequate blood flow into the pulmonary circulation at a normal central venous pressure. This condition is often a
result of pulmonary disease and the resulting elevated pulmonary vascular resistance.
1. In systolic heart failure, what effect does the renin-angiotensin-aldosterone system (RAAS) have on stroke
volume?
a. Increases preload and decreases afterload.
b. Increases preload and increases afterload.
P 2
, • NURS 6501EXAM 09/13/2026
c. Decreases preload and increases afterload.
d. Decreases preload and decreases afterload. –
Correct Answer :Increases preload and increases afterload. Activation of the RAAS not only causes an increase
in preload and afterload, but it also causes direct toxicity to the myocardium.
1. What is the cause of the dyspnea resulting from a thoracic aneurysm?
a. Pressure on surrounding organs
b. Formation of atherosclerotic lesions
c. Poor oxygenation
d. Impaired blood flow –
Correct Answer :Pressure on surrounding organs. Clinical manifestations depend on the location of the
aneurysm. Pressure of a thoracic aneurysm on surrounding organs cause symptoms of dysphagia (difficulty in
swallowing) and dyspnea (breathlessness).
1. Which statement is true concerning the cells' ability to synthesize cholesterol?
a. Cell production of cholesterol is affected by the aging process.
b. Cells produce cholesterol only when dietary fat intake is low.
c. Most body cells are capable of producing cholesterol.
d. Most cholesterol produced by the cells is converted to the low-density form. –
Correct Answer :C. Although cholesterol can easily be obtained from dietary fat intake, most body cells can also
manufacture cholesterol.
1. What is the trigger for angina pectoris?
a. Atherosclerotic lesions
b. Myocardial necrosis
c. Hyperlipidemia
d. Myocardial ischemia - Correct Answer :Myocardial ischemia. Angina pectoris is chest pain caused by
myocardial ischemia.

1. Individuals being effectively managed for type 2 diabetes mellitus often experience a healthy decline in blood
pressure as a result of what intervention?
a. Managed carbohydrate intake
b. Appropriate exercise
c. Insulin-sensitivity medication therapy
d. Introduction of minimal doses of insulin –
Correct Answer :C. Many people with type 2 diabetes mellitus, who are treated with drugs that increase insulin
sensitivity, experience a decline in their blood pressure without taking antihypertensive drugs.
1. Which statements are true regarding fatty streaks? (Select all that apply.)
a. Fatty streaks progressively damage vessel walls
b. Fatty streaks are capable of producing toxic oxygen radials.
c. When present, inflammatory changes occur to the vessel walls.
d. Oxidized low-density lipoproteins (LDLs) are involved in their formation.
e. Fatty streaks are formed by killer T cells filled with oxidized LDLs.
- Correct Answer :A, B, C, D. The oxidized LDLs penetrate the intima of the arterial wall and are engulfed by
macrophages. Macrophages filled with oxidized LDLs are called foam. Once these lipid-laden foam cells
accumulate in significant amounts, they form a lesion called a fatty streak. Once formed, fatty streaks produce
more toxic oxygen radicals and cause immunologic and inflammatory changes, resulting in progressive damage
to the vessel wall.
1. What are clinical manifestations of hypothyroidism?
a. Intolerance to heat, tachycardia, and weight loss
b. Oligomenorrhea, fatigue, and warm skin
c. Restlessness, increased appetite, and metrorrhagia
d. Constipation, decreased heart rate, and lethargy - Correct Answer :The lower levels of thyroid hormone result
in decreased energy metabolism, resulting in constipation, bradycardia, and lethargy, thus eliminating the
remaining options.
