Test 33/34 Flashcards
Stages of nuclear blast
- Blinding light flash
- Fireball or thermal pulse
- Blast itself, in which atmosphere expands
- Electromagnetic pulse
- Fallout (majority in first 24-48 hours)
3 clinical ranges of radiation exposure
- Subclinical
- Clinical-sublethal
- Lethal
Nausea and vomiting at what time frame in radiation if lethal dose
Less than 1 hour
Perimortem C section incision
Pubis to umbilicus
Can extend to xiphoid if needed
Tx for eviscerated bowl
Cover with sterile saline soaked dressing and cover with dry occlusive dressing
do not attempt to clean or put back in
Most likely devices to not accommodate bariatric patients
Immobilization devices and traction splints
ETCO2 in asthmatic that is concerning? What does it suggest
Normal or above normal - sign of respiratory failure
HF acid binds to what
Intracellular calcium and magnesium
HF acid lab abnormalities
Hypocalcemia
Hypomagnesemia
Hyperkalemia
Huber needle is needed to access what
Chemo port
Quarantine after anthrax exposure?
Not needed - human to human transmission is rare
Minimum flow for jet ventilation
50 lpm
Where should tip of IABP be on CXR
2nd and 3rd intercostal spaces
Placed 1-2 cm distal to beginning of subclavian artery
What to do when lots of bystanders around causing problem
Call law
Standard equipment for what procedure doesn’t work in bariatric patients
Needle decompression
Class A bioterrorism agents
Anthrax
Botulism
Yersinia pestos
Smallpox
Tularemia
Viral hemhorragic fevers (flavor virus, ebola, Marburg)
Leading causes of death in LVAD patients
- Heart failure
- Infection
- Stroke
- Device malfunction (rare)
Decontamination for gas or vapor exposure
Removal from site should be sufficient
4 forms of botulism
Foodborne
Wound
Intestinal
Inhalation
Transport position for umbilical cord prolapse
Knee to chest position or in steep trendelenburg position to aid in reducing pressure on the cord
SARS transmission
Initially large drops and later by indirect contact
Avoid Nitro for 48 hours with what drug
Tadalafil
Why is tap water less preferred for eye irrigation
It may force corrosive substances into the cornea and worsen outcomes due to its relative hypotonicity to the eye itself
Why is Sodium Nitrite contraindicated when there is CN and CO poisoning
Induces methemoglobinemia, further reducing oxygen carrying capacity
Most infectious forms of body fluid
CSF
Synovial fluid
Pleural fluid
Pericardial fluid
Amniotic fluid
Blood
Risk factors for umbilical cord prolapse
- Abnormal presentation of the fetus
- Lack of prenatal care
- Twins (2nd born twin)
- Gestational diabetes
More likely to cause respiratory depression: IN vs PR midazolam
PR
Diphenhydramines MOA
H1 antagonist
No effect on histamine release
Longest peak effect of prehospital sedatives
Lorazepam (60-90 minutes)
Guidelines for activities in radioactive zones based on radiation level
5 rem - all activities
10 rem - protect major property, save lives, protect large populations
25 rem - only saving lives/protecting large populations
First line treatment in pregnant patient with V-tach and pulse
- Lidocaine
- Procainamide
