Asterile urine specimen for culture and sensitivity has been ordered for a client who has an indwelling urinary catheter. how should the nurse obtain this specimen? collect a urine specimen from the collection bag first thing in the morning, or a few hours after the client receives a diuretic. empty the collection bag, wait 30 minutes, and then collect the contents of the collection bag. discontinue the indwelling catheter and insert an intermittent catheter to obtain the sterile specimen. withdraw several milliliters of urine from the port on the collection tubing, using a syringe and needle.

Zoe decided to measure the hand length of each of her classmates. first she marked a line across each student's wrist and lined up a ruler from this mark to the top of the middle finger to measure the length. then she recorded the measurements in the table below. marla did this the same way for each classmate, and then zoe used this ruler to measure each straight line and record the data below. this data is invalid. what is the most likely reason why it is invalid? the ruler is marked in centimeters, but zoe recorded data in inches. the range of lengths is too wide, so zoe must have misread the ruler. marla’s complicated measuring procedure was overly confusing. marla could have been inconsistent while drawing outlines of fingers.

Suppose that on a small island off the coast of scotland, 32 percent of the population has blue eyes, which means that these individuals must be homozygous for the blue eye color gene (bb). the only other eye color found on the island is brown, and individuals that are homozygous for the brown eye color gene (bb) or heterozygous (bb) will have brown eyes because brown is the dominant gene. assume this population is in hardy-weinberg equilibrium. if 100 babies are born next year, how many of these would you expect to have brown eyes and be heterozygous? a. 58 b. 49 c. 29 d. 43
