Q

CNS symptoms during anaphylactic shock

Study These Flashcards
A

  • LOC changes
  • seizures
  • headache
19
Q

amount of epinephrine to give for children 8-25kg

Study These Flashcards
A

0.15mg (EpiPen Jr.)

20
Q

amount of epinephrine to give for children > 25kg

Study These Flashcards
A

0.3mg (EpiPen)

21
Q

amount of epinephrine to give (first like rescue med)

Study These Flashcards
A

0.01 mg/kg to 0.3 mg/kg

22
Q

type of shock that causes massive vasodilation and capillary leakage
(maldistribution of blood)

23
Q

signs of septic shock

Study These Flashcards
A

fever, high WBCs

24
Q

type of shock that may appear like hypovolemic shock, but the cause is different (mechanical)
–there is a road block

Study These Flashcards
A

obstructive shock

25
4 types of obstructive shock
1. tension pneumothorax 2. cardiac tamponade 3. pulmonary embolism 4. congenital heart lesion
26
tension pneumothorax
(type of obstructive shock) -build up of air/fluid/blood and causes compression of lungs
27
cardiac tamponade
(type of obstructive shock) - buildup and causes compression of lungs, but it is PULLING around the heart - result of trauma, cardiac surgeries
28
pulmonary embolism
(type of obstructive shock) -blockage (restricting blood's ability to go to the lungs)
29
congenital heart lesion
(type of obstructive shock) - the heart is restructured (looks very different) - actual blockages and things are not running correctly
30
s/s of compensated shock
- apprehension - irritability - normal BP - narrowing pulse pressure - thirsty - pale - decreased urine output - mild tachycardia - decreasing peripheral perfusion
31
s/s of uncompensated shock | hypotensive
- chills/fever - increased vasodilation - may have warm extremities initially - tachypnea - oliguria - cool, pale extremities - change in LOC - tissue hypoxia leading to organ death - metabolic acidosis - DIC (disseminated intravascular coagulation)
32
treatment/intervention to improve oxygenation and ventilation
- administer O2 as ordered - intubation (lung rest) - check blood gasses (oxygenation status) - oxygen saturation - PH monitoring
33
treatment/intervention to improve heart function
- vasopressors--> produces vasoconstriction | - inotropes--> helps heart stimulate and strengthen heart contractions (Epinephrine, calcium, etc.)
34
treatment/interventions for fluid administration:
- isotonic crystalloid (NS or LR) - bolus at 20ml/kg over 5-20 min - blood products - colloids (albumin) - FFP to correct coagulopathies
35
what is toxic shock sydrome caused by?
staphylococcus bacteria
36
what product has a well-known association with TSS?
tampons
37
ways to get toxic shock syndrome
- sinusitis - pneumonia - catheter infections - skin infections - wound infections - nasal packing - contraceptive diaphragms - IUDs
38
what will TSS look like?
- sudden temp of 38.9 (102 F) or higher - vomiting and diarrhea - macular erythroderma (red rash) - hypotension - late sign is desquamation of palms
39
identify the shock: a patient presents with hypotension, rapid pulse and respirations, and x-ray shows a large pulmonary embolism
obstructive
40
identify the shock: a child has suffered a tragic amputation and rescue personnel are having a difficult time stopping the bleeding
hypovolemic
41
identify the shock: margo was in a house fire and was burned over 70% of her body
hypovolemic
42
identify the shock: jeremy took a bite of his friend's PB&J. his lips immediately began to swell and his breathing became labored
anaphylactic
43
identify the shock: kate is post-op from a AVSD surgery. she was doing fine, but started to look pale and the ECG monitor showed SVT
cardiogenic
