Question 1

What should your attitude be towards infants that are inconsolable?

Answer 1

They warrant immediate further treatment (31 RF)

Question 2

Compare a peds stroke volume to that of an adult?

Answer 2

Peds SV is fixed due to a lack of myocardial stretch so in order for CO to increase HR must increase in peds. (33)

Question 3

What are some physiologic causes of a higher respiratory rate in children?

Answer 3

A lack of tidal reserves and increased cellular o2 consumption. (33)

How much volume will be lost before a ped exhibits a decrease in blood pressure? (range as a percent)

Answer 4

25-50% of volume is lost (34 RF)

the bones are softer and more prone to bending. When fractures are present consider maltreatment of significant underlying injury (35RF)

What should you consider monitoring in ped with altered mental status?

Answer 15

Glucose. children have smaller glucose stores in the liver and increased glucose consumption by the brain. (36 RF)

Answer 23

Their parasympathetic nervous system is more pronounced and easier to stimulate (35)

Question 24

How might a nurse easily determine that the patient likely has a congenital heart defect?

Answer 24

POX Is measured on the RIGHT hand and compared to the foot. If the difference is more than 3% could indicate a CHD (35 P)
