Aclient with type 2 diabetes who requires insulin asks the nurse about having alcoholic beverages. which is the best response by the nurse? "alcohol is detoxified in the liver, so it is not a good idea for you to drink anything with alcohol." "if you have a drink, the blood glucose value may be elevated at bedtime, and you should skip having a snack." "if you are going to drink, it is best to consume alcohol on an empty stomach." "you can have one or two drinks a day as long as you have something to eat with them."

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
