Drugs acting on the renal system
7.
Women tend to have more problems with bladder
infections than men because:
a.
women have
E. coli
in the urinary tract.
b.
women have a short urethra, making access to
the bladder easier for bacteria.
c.
the prostate gland secretes a substance that
protects men from bladder infections.
d.
women’s urine is more acidotic, encouraging the
growth of bladder bacteria.

Considering the metabolic functions of the kidneys,
renal failure would be expected to cause which of
the following?
a.
anaemia
b.
loss of calcium regulation
c.
urea buildup on the skin
d.
respiratory alkalosis
e.
metabolic acidosis
f.
changes in the function of blood cells
2.
During severe diarrhoea, there is a loss of water,
bicarbonate and sodium from the gastrointestinal
tract. Physiological compensation for this would
probably include which of the following?
a.
increased alveolar ventilation
b.
decreased hydrogen ion secretion by the renal
tubules
c.
decreased urinary excretion of sodium and water
d.
increased renin secretion
e.
increased hydrogen ion secretion by the renal
tubules
f.
increased ADH levels
3.
Maintenance of blood pressure is important in
maintaining the fragile nephrons. Reflex systems
that work to ensure blood flow to the kidneys
include:
a.
the renin–angiotensin system causing
vasoconstriction.
b.
baroreceptor monitoring of the renal artery.
c.
aldosterone release secondary to angiotensin
stimulation.
d.
ADH release in response to decreased blood
volume with increased osmolarity.
e.
release of erythropoietin.
f.
local response of the afferent arterioles.
