(1.0 point)Your 23-year-old patient presents with symptoms of dysuria, urinary frequency and urgency x 2 days. No other symptoms. She is sexually active with male partners (IUD for contraception) and has never had this before. You order a urine dip and the findings are significant for:Positive leukocytes (moderate)Trace nitritesYour next step includes:

(1.0 point)A patient with sciatica will usually report:

(1.0 point)Chronic cough is defined as a cough lasting longer than: 

What is the total area under the standard normal distribution curve?

The normal distribution is described by the mean and standard deviation. Increasing the value of the standard deviation will have what effect on the shape of the distribution?
