Shock Ch. 10

Question 1

Signs of compensated shock (6)

Answer 1

1. slight tachy, 2. slight delayed cap refill, 3. subtle mental changes, VASOCONSTRICTION leading to 4. slight ^ in DBP, 5. Narrow PP

Question 2

Signs of early WARM septic shock (3)

Answer 2

1. bounding pulse, 2. flash cap refill < 1 sec. , 3. WIDENED PP

Memory aid: “WARM = Wide Open”
Vasocdialtion leads to increased blood lfow, leading to bounding pulse, fast cap refill and wide PP as the dilation decreases the DBP.

Question 3

Hypotensive decompensated shock signs ? (7)

Answer 3

1. ^ tachy, 2. tachypnea 2* acidosis, 3. 3rd spacing of fluid, 6. < mental status, 7. cyanosis/mottling, 8. < cap refill, 9. DIC

Question 4

neonate hypotension range

Answer 4

<60 mm Hg

Question 5

Infant hypotension range

Answer 5

<70 mm Hg

Question 6

Child 1-10 yo hypotension range

Answer 6

<70 + 2X age in years mm Hg

Question 7

Child >10 yo hypotension range

Answer 7

<90 mm Hg

Question 8

Irreversible shock signs

Answer 8

multi organ failure

Question 9

Two causes of a WIDENED PP?

Answer 9

Vasodilation casued by either 1. ^ ICP, or early septic shock

Question 10

One cause of a NARROW pulse pressure?

Answer 10

Vasoconstriction from hypovolemic shock

Question 11

What is preload?

Answer 11

The amount of blood returning to the heart.

Question 12

What is afterload?

Answer 12

The amount of resistance blood leaving the left ventricle must overcome to enter the peripheral circulation.

Question 13

How can tachycardia effect preload?

Answer 13

By reducing filling times

Question 14

What BP parameters indicate an increase in SVR?

Answer 14

A narrow pulse pressure and increased DBP
