17
Q

Third spacing

A

Fluid going into interstitial spaces

18
Q

Sepsis treatment

A

Reverse vasodilation
Remove cause
Maintain tissue perfusion

19
Q

Fluid resuscitation

A

Crystalloid fluids: NS and LR

20
Q

Levophed

A

Norepinephrine vassoconstrictor

21
Q

Lactate levels

A

Normal is 0.5-2.4

22
Q

Neurogenic shock

A

Loss of sympathetic tone resulting in dilation.

Temporary associated with spinal cord injury

23
Q

Treatment of neurogenic shock

A

Drugs to improve vasomotor tone
Reverse vasodilation
Maintain tissue perfusion

24
Q

Fluids with neurogenic shock

A

Be cautious with fluid use. Opt to use vasoconstrictors instead.

25
Q

Dopamine

A

Vasoconstrictor treats bradycardia

26
Q

Anaphylactic shock

A

Result of allergic reaction. Causes respiratory distress. Can be life threatening.

27
Q

Treatment of anaphylactic shock

A

MAINTAIN AIRWAY BY WHATEVER MEANS NECESSARY

28
Q

Epinephrine

A

Drug of choice of anaphylaxis. Bronchodilator counteracts histamine response

29
Q

Corticosteroids

A

Use in anaphylaxis to decrease inflammation
