Which of the following is correct about shock in child?

Which of the following is correct about
shock in child?
a) Tachycardia is a very sensitive indicator of depletion of
intravascular volume
b) Mottling of extremities is seen in early shock
c) Confusion, stupor and coma are early signs
d) Respiratory rate is more sensitive than heart rate as an
indicator of early shock
Correct Answer - A
Answer- A. Tachycardia is a very sensitive indicator of
depletion of intravascular volume
Hypovolemic shock in children may have following stages : -
i) Early compensated
Immediately after hypovolemia, body tries to maintain the BP to
maintain adequate perfusion to vital organs through a compensatory
mechanisms.
An increase in heart rate (Tachycardia) is the earliest and most
sensitive indicator for intravascular volume reduction
ii) Late uncompensated
If shock state continues or the compensatory mechanisms are not
enough to maintain the metabolic needs of the tissue, the shock,
goes into uncompensated phase.
