A GP suspects that his young patient has cranial diabetes insipidus. This is a disorder in which the pituitary gland fails to release ADH when stimulated to do so. She is referred for a water deprivation test during which she is nil by mouth?

Blood 300/urine 100

1 of 6

You examine a patient and note he has lower leg pitting oedema. You also note that his blood albumin level is low. Which statement correctly describes the relationship between albumin and oedema?

A low albumin causes a decrease in oncotic pressure and water diffuses from the blood into the interstitial fluid
