Phil used a chemical solution to indicate the presence of carbon dioxide in the water. When the solution is put into water it turns green. As carbon dioxide is added to the water and chemical solution it will turn yellow. Predict which tubes in Phil's experiment will be yellow after 24 hours?

Anurse is preparing to administer ampicillin 500 mg in 50 ml of dextrose 5% in water (d5w) to infuse over 15 min. the drop factor of the manual iv tubing is 10 gtt/ml. the nurse should set the manual iv infusion to deliver how many gtt/min? (round the answer to the nearest whole number. use a leading zero if it applies. do not use a trailing zero.)
