A couple of questions from exam yesterday structured in a different light. Qu on sleep credits - maximum length of sleep useful for sleep credits, I chose option of 16 hrs (wrong) as I remembered that number from text. Correct answer would have been 8 giving 16 sleep credits. Another was blue fingernails lips etc. the 2 feasible answers were hypoxia and CO poisoning. As blue fingernails are a sign of advanced hypoxia I figured that the better answer was CO poisoning as CO would prevent oxygen from attaching to Hb from the start. (wrong). Hope this helps.

Hi Peter, thanks for the feedback on the exam and congratulations on the pass - excellent :-)

Just to clarify, CO poisoning won't give you blue fingertips because the CO molecules bind with Haemoglobin producing carboxyhaemoglobin which has a bright red colour. Because of this, CO poisoning will be associated with red fingertips as well as all the other symptoms you're familiar with.
