kidneys will be excreting more acid to compensate for the high arterial carbon dioxide level.

Premature babies may deveop great difficulty breathing immediately after birth, and have to make huge
efforts to breathe - a condition known as infant respiratory distress syndrome. If this occurred, they
would be given a particular drug via a breathing tube. What would this drug do? - Correct Answer It
would reduce the surface tension in the alveoli of the lungs, allowing the babies to inflate their lungs
more easily
Soft bones (osteomalacia) and rickets can be a problem in people who keep their entire skin surface
covered most of the time, for example, muslim women who wear a burka. Why would this be? - Correct
Answer Bones rely on their calcium content to make them hard, and calcium absorption into the body is
dependent on the active form of vitamin D. Vitamin D is converted to an active form by the action of
sunlight on the skin. If the skin does not get any sunlight on it, then this process will not occur, and bones
will become soft.
The glucose tolerance test is used to diagnose diabetes. The test involves giving the subject a glucose
drink, and then monitoring the blood level of glucose at intervals afterwards. How does this test show
whether a person has diabetes or not? - Correct Answer In a healthy person, the blood glucose level
should rise rapidly after drinking the glucose drink, but should drop to pre-test levels within 2 hours, as
insulin will have caused the removal of glucose from the blood stream into cells.
Urine dipsticks are a quick and easy way to check for a range of substances in the urine. If the dipstick

results suggest something is not quite right.
