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?

You are giving chest compressions for a child in cardiac arrest. What is the proper depth of compressions for a child?

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?

Which oxygen delivery system most reliably delivers a high (90% or greater) concentration of inspired oxygen to a 7-year-old child?

A 3-month-old infant is intubated for management of respiratory failure.  During transport, the infant develops bradycardia with a heart rate of 60/min, and the infants oxygen saturation decreases to 75%.  There are breath sounds on the right side, but no air entry is heard on the left side.  What is the most appropriate initial intervention?

What is the appropriate fluid bolus to administer for a child with hypovolemia shock with adequate myocardial function?

All these are unique attributes of a child airway except:

A 10-year-old child has a sudden witnessed cardaic arrest and recieves immediate bystander CPR and defibrillation within 3 minutes.  He had return of spontaneous circulation.  The child remains unresponsive and has an advanced airway in place.  There is no history of trauma or signs of shock.  What is the target range for oxygen saturation for this child? 

A 2-year-old was found submerged in a swimming pool.  She is unresponsive and not breathing, and is pulseless.  In addition to performing high-quality CPR and establishing vascular access, which of the following is the most appropriate intervention?

An alert 2-year-old with an increased work of breathing and pink color is being evaluated.  Heart rate is 110/min. and respiratory rate is 30/min.  What would best discribe this patient’s condition?
