Online Modules Flashcards
What does KE= 1/2 mvsquared mean in layman’s terms?
If mass doubles, energy doubles, when velocity doubles, energy is quadrupled.
How many impacts are involved in an MVA?
- First, car hits something. Second, a persons body hits the inside of the car. Third, the internal organs impact the body.
What is cavitation?
Separation of tissue due to sound or hydraulic waves.
Which organs are more prone to damage due to cavitation?
Solid organs like the liver.
What organs does the primary blast injuries affect?
Air filled organs like the lungs.
What type of blast injuries cause the most fatalities?
Secondary, which include fragment injuries and implements.
What type of injury is considered a tertiary blast injury?
When the body is thrown against an object, fractures such as the pelvis are likely to occur.
Name the cardiovascular changes that may occur during pregnancy that may affect resuscitation.
Blood volume increases, which increases tolerance to blood loss, HR increases 10-20 BPM, after 20 weeks supine hypotension may occur, vasodilation occurs, which may make a Pt in shock appear warm/dry.
What are some respiratory changes that may affect the Tx of a pregnant woman.
O2 consumption increases, RR increases, risk of nasopharyngeal bleeding increases, which increases risk of upper airway obstruction, chest tube placement needs to be higher due to higher diaphragm.
Name some hematologic changes affecting the Tx of a pregnant woman.
Plasma volume volume increases 30-50% by the 13th week. risk of thromboembolism and DIC increases.
What are some gastrointestinal changes affecting the Tx of a pregnant woman.
Abdominal organs displaced, abdominal palpation less reliable, bowel sounds less audible, emptying time prolonged, more gastric secretions make reflux/aspiration more likely.
Name some renal changes affecting the Tx of a pregnant woman.
Increased frequency, increased risk of UTI due to stasis.
Name some musculoskeletal changes affecting the Tx of the pregnant Pt.
Sacral ligaments soften and relax. unsteady gait due to widening pelvis/abdomen.
What accounts for most trauma among pregnant women?
Falls and blunt trauma.
What equipment is needed to prepare for the pregnant trauma Pt?
Fetal monitor, emergency delivery pack, infant warmer.
If your pregnant trauma Pt has retractions, what would you do?
Apply oxygen at 15L via non-rebreather mask.
How would you treat a suspected case of supine hypotension syndrome who presents on a backboard?
Tilt the backboard at least 15 degrees with a hip wedge, or manually displace the uterus to the side.
If your pregnant Pt with a glasgow score of 15 suddenly drops to a 7,with snoring respiration’s, what are the interventions you should take?
Open airway with jaw thrust, insert OPA, ventilate via bag mask, prepare to intubate, request head CT, consider OG tube.
What are the steps to confirming correct ETT placement?
Bilateral breath sounds, bilateral chest rise and fall, no gurgling over epigastrium, attach carbon dioxide detector and check level after 5-6 breaths.
What are the weight ranges for classifying an individual as underweight/normal weight/overweight/obese?
BMI
What type of MVA/injuries are more prevelant to bariatric patients?
More fatalities with frontal crashes. Pt more prone to head/thoracic/abdominal/extremity injury/fracture.
When dosing analgesic meds for the bariatric Pt, is actual weight or ideal weight used to determine dosing?
Ideal body weight.
What are 2 quick ways to check clear nasal drainage for the presence of CSF?
Place a drop on gauze and look for a halo, and test for glucose.
