A shift to the right in the hemoglobin dissociation curve means that: the affinity of hemoglobin for O2 has decreased. the CO2 levels in the blood have decreased. the pH of the blood has increased. the hemoglobin protein has denatured. less O2 is released by hemoglobin to the body cells.

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.)
