Misc PEM Q Book Flashcards
lab abnormality in hereditary angioedema
low C4
reasons to use VariZig
only for post-exposure ppx, but NOT once there is varicella infection
lab abnormalities in strep glomerulonephritis
low C3, nml C4.
if levels are normal, consider something else
non-ketotic hypoglycemia with metabolic acidosis should make you think of…
fatty acid oxidation disorder
classic lab findings in fatty acid oxidation disorder
non-ketotic hypoglycemia
anion gap formula
AG = Na - Cl - HCO3
calculated osmolarity
= 2 x Na + glucose/18 + BUN/2.8
Multi-casualty vs mass casualty event
multi-casualty = 5+ victims
mass casualty = strains the existing EMS system
what’s unique about the sterile pyuria of Kawasaki disease?
it is lymphocyte predominant
What can different levels of responders do: first responders? EMT-B? EMT-I? EMT-P?
1st responders: airway clearance, control blood loss, AED, CPR
EMT-B: assessment, spinal immobilization, BVM, defibrillation
EMT-I: pacing, cardioversion, IO, EKG, needle thoracostomy, advanced airway management
EMT-P: arrhythmias, advanced airway management, intubation, cricothyrotomy, meds, fluids
Best pressors for shock that is:
- cold
- warm
- normal BP
- epi
- norepi
- dopa
CXR findings (measurements) for RPA
prevertebral soft tissue swelling >7mm at C2 or 14mm at C6
Lab findings concerning for a pulmonary EXUDATE
WBC >10K glucose < 50% of serum protein > 50% of serum amylase > 200 LDH > 60% of serum pH < 7.0 (v. suggestive of empyema)
EKG findings in pericarditis
widespread ST elevation
PR depression
ST elevation in limb and precordial leads with concave elevations
Location for ____ nerve block at wrist:
1) ulnar
2) median
3) radial
1) ulnar - proximal ventral crease at ulnar styloid
2) median - medial tendon of flexor carpi radialis
3) radial - dorsal crease @ radial styloid
pressure readings associated with compartment syndrome
> 30 mmHg
Components of the pediatric trauma score
- size
- airway
- consciousness
- SBP
- fractures
- cutaneous
How do you determine size for:
- ET tube
- ET tube depth of insertion
- NG tube size
- chest tube size
- ET tube = age/4 + 4
- ET tube depth of insertion = ETT x 3
- NG tube size = ETT x2
- chest tube size = ETT x 4
