MULTIPLE CHOICE
1. Activation of parasympathetic nerves to the bladder will cause
a. bladder contraction.
b. bladder relaxation.
c. sphincter contraction.
d. urine reflux.
ANS: A
Stimulation of the parasympathetic nerves to the bladder will cause bladder contraction. Stimulation of the sympathetic nerves to
the bladder will cause bladder relaxation and allow for storage of urine. Stimulation of the parasympathetic nerves to the bladder
will cause bladder, not sphincter, contraction. Stimulation of the parasympathetic nerves to the bladder does not cause urine reflux.
REF: Pgs. 610-611
2. Urinary retention with consistent or intermittent dribbling of urine is called
a. mixed incontinence.
b. enuresis.
c. stress incontinence.
d. overflow incontinence.
ANS: D
Urinary retention with consistent or intermittent dribbling of urine is called overflow incontinence. Mixed incontinence is a
combination of both stress and urge incontinence. Enuresis is incontinence while asleep. Stress incontinence is involuntary loss of
urine due to increases in intra-abdominal pressure.
REF: Pg. 612
3. Detrusor muscle overactivity can be improved by administration of
a. alpha-receptor agonists.
b. botulinum toxin.
c. cholinergic agents.
d. nonsteroidal antiinflammatory agents.
ANS: B
Detrusor muscle overactivity can be improved by administration of botulinum toxin. Alpha-receptor agonists will not treat detrusor
muscle overactivity. Anticholinergic drugs will treat this condition. NSAIDS are for pain, inflammation, and fever.
REF: Pg. 613
4. The direct cause of stress incontinence is
a. the effect of aging.
b. pelvic muscle weakness.
c. neurologic conditions.
d. detrusor muscle overactivity.
ANS: B
The primary cause of stress incontinence is loss of pelvic muscles and/or fascial support of the bladder and urethra. Although aging
weakens the pelvic muscles, it is not the direct cause of stress incontinence. Neurologic conditions cause neurogenic bladder which
can lead to incontinence but this is not the same as stress incontinence. Overactivity of the detrusor muscle leads to urge
incontinence.
REF: Pg. 612
5. Which group is at the highest risk for urinary tract infection?
a. Infants and children
b. Sexually active women
c. Adult males
d. Patients taking diuretics
ANS: B
Sexually active women are at the highest risk for urinary tract infection. Infants and children, adult males, and patients taking
diuretics are not at the highest risk for urinary tract infection.
