.
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.
c. Decreases preload and increases afterload.
d. Decreases preload and decreases afterload. - correct answer ANS: B
Activation of the RAAS not only causes an increase in preload and afterload, but it also
causes direct toxicity to the myocardium. This selection is the only option that
accurately identifies the effect that the RAAS has on stroke volume in this situation.
What factors contribute to the development of orthostatic hypotension? (Select all that
apply.)
a. Altered body chemistry
b. Drug action of certain antihypertensive agents
c. Prolonged immobility
d. Effects of aging on postural reflexes
e. Any condition that produces volume overload - correct answer ANS: A, B, C, D
Orthostatic hypotension may be acute or chronic. Acute orthostatic hypotension
(temporary type) may result from (1) altered body chemistry, (2) drug action (e.g.,
antihypertensives, antidepressants), (3) prolonged immobility caused by illness, (4)
starvation, (5) physical exhaustion, (6) any condition that produces volume depletion

(e.g., massive diuresis, potassium or sodium depletion), and (7) venous pooling (e.g.,
pregnancy, extensive varicosities of the lower extremities). Older adults are
susceptible to this type of orthostatic hypotension, in which postural reflexes are
slowed as part of the aging process
Which assessment findings are clinical manifestations of aortic stenosis? (Select all
that apply.)
a. Jugular vein distention
b. Bounding pulses
c. Hypotension
d. Angina
e. Syncope - correct answer ANS: D, E
The classic manifestations of aortic stenosis are angina, syncope, and heart failure.
None of the other options are associated with aortic stenosis.
Which statement best describes cystic fibrosis?
a. Obstructive airway disease characterized by reversible airflow obstruction,
bronchial hyperreactivity, and inflammation
b. Respiratory disease characterized by severe hypoxemia, decreased pulmonary
compliance, and diffuse densities on chest x-ray imaging
c. Pulmonary disorder involving an abnormal expression of a protein-producing
viscous mucus that obstructs the airways, pancreas, sweat ducts, and vas deferens
d. Pulmonary disorder characterized by atelectasis and increased pulmonary
resistance as a result of a surfactant deficiency - correct answer ANS: C
