The perioperative nurse is caring for a client who requires an umbilical hernia repair but who has a known family history of malignant hyperthermia. the client has been prescribed dantrolene 2.5 mg/kg iv one hour before surgery. the client weighs 121 lbs. the nurse reconstitutes a single-use vial as per the manufacture's instructions, yielding a solution with a concentration of 50 mg/ml. how many ml of the reconstituted dantrolene solution should the nurse add to the client's bag of intravenous fluid?

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

hope this .. .
