The registered nurse anesthetist has administered a small dose of nondepolarizing neuromuscular junction (nmj) blocker before administering succinylcholine. what outcome most clearly indicates therapeutic effect of this action?

Administering a small dose of nondepolarizing NMJ blocker prior to succinylcholine introduction has the immediate effect of lessening the potency of succinylcholine and requiring a higher dosage to have the desired effect. This technique, called precurarization, is used to lessen post-treatment muscle pain that is a common after effect of succinylcholine, due to the muscular fasciculations (muscle twitches) that occur during the Phase 1 block. This muscle pain occurs most frequently in those that may have a larger muscle mass (i.e. younger and healthier adults) and shows up in atypical places, such as the diaphragm, intercostal muscles and between the scapulae.

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait.
