HUBS1406 Kidneys practice test Questions With Complete
Solutions
A chemical that minimises changes in the pH of a body fluid by
releasing or binding hydrogen ions, depending on the conditions,
is known as a/an: Correct Answers buffer.
A glomerular filtration rate of 50 mls per minute would be
classified as: Correct Answers renal failure
A normal glomerular filtration rate (GFR) for healthy kidneys is:
Correct Answers 125 ml/minute
A patient is found to have artery disease which has led to the
partial blockage of both of her renal arteries, reducing blood
flow through the kidneys. The kidneys are still functioning
normally. Which of the following might be expected as a result
of this? Correct Answers Activation of the renin-angiotensin
system, leading to increased blood pressure
A patient produces large volumes of very dilute urine on a
continuing basis. This could be caused by: Correct Answers
abnormally low ADH secretion
A person has lost a lot of blood after cutting himself. Which of
the following would be likely to occur as a result of the blood
loss? Correct Answers Increased renin secretion
A person with chronic obstructive pulmonary disease is unable
to ventilate their lungs properly. Their kidneys are likely to
respond to this by: Correct Answers Both B and C awnser
, increasing excretion of hydrogen ions
retaining more bicarbonate ions
A person with chronic renal failure is likely to suffer from:
Correct Answers itchy skin
A person with chronic renal failure may have weak bones
because Correct Answers the effects of acidosis and
parathyroid hormone would combine to decrease the minerals in
bone
A person with kidney failure has difficulty excreting the acid
load created by their diet and metabolic processes. What
compensation would you expect to occur in this person? Correct
Answers Increased rate and depth of ventilation
drug that inhibits angiotensin converting enzyme (ACE) would
cause: Correct Answers less secretion of aldosterone.
Excess hydrogen ions are eliminated from the body largely by:
Correct Answers the kidneys.
he primary role of the carbonic-acid-bicarbonate buffer system
is to Correct Answers limit blood pH changes caused by acids.
How is the kidney involved in the maintenance of the
haematocrit? Correct Answers By the production of
erythropoietin
Hypoventilation would tend to result in: Correct Answers high
plasma CO2 levels and low pH
