A 4-year-old child is being treated for hypovolemic shock and has recieved a single fluid bolus of 20 mL/kg of normal saline.  On reevaluation the child remains anxious, with a heart rate of 140/min., a blood pressure of 84/54 mm Hg, and a capillary refill time of 4 seconds.  What describes this patients condition?

A 2-year old child present with a history of vomiting.  The initial impression reveals an unresponsive child with intermitant apnea and mottled color.  Heart rate is 166/min., respiratory rate is now being supported with bag-mask ventiation, capillary refill time is 5-6 seconds, and temperature is 102F (38.9C).  What is the best method of establishing immediate vascular access?

Big canines (B) is a dominant, autosomal trait in dogs. A male dog with big canines was crossed with a pure-breeding wild type b (normal) female dog. Of their progeny (F1) 1/2 had big canines and 1/2 were wild type. When two of those dogs with big canines (F1) were mated, their progeny (F2) contained 295 with big canines and 105 of the wild type. The geneticist’s hypothesis is that both of the F1 parent dogs crossed were heterozygous for b and B, so she thinks that the ratio of progeny of the second cross (F2) is 3:1. Is her hypothesis correct?
