Q

What does KE= 1/2 mvsquared mean in layman’s terms?

If mass doubles, energy doubles, when velocity doubles, energy is quadrupled.

2
Q

How many impacts are involved in an MVA?

A
  1. First, car hits something. Second, a persons body hits the inside of the car. Third, the internal organs impact the body.
3
Q

4
Q

A

Solid organs like the liver.

5
Q

What organs does the primary blast injuries affect?

A

Air filled organs like the lungs.

6
Q

What type of blast injuries cause the most fatalities?

A

Secondary, which include fragment injuries and implements.

7
Q

What type of injury is considered a tertiary blast injury?

A

When the body is thrown against an object, fractures such as the pelvis are likely to occur.

8
Q

Name the cardiovascular changes that may occur during pregnancy that may affect resuscitation.

A

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.

9
Q

What are some respiratory changes that may affect the Tx of a pregnant woman.

A

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.

10
Q

Name some hematologic changes affecting the Tx of a pregnant woman.

A

Plasma volume volume increases 30-50% by the 13th week. risk of thromboembolism and DIC increases.

11
Q

What are some gastrointestinal changes affecting the Tx of a pregnant woman.

A

Abdominal organs displaced, abdominal palpation less reliable, bowel sounds less audible, emptying time prolonged, more gastric secretions make reflux/aspiration more likely.

12
Q

Name some renal changes affecting the Tx of a pregnant woman.

A

Increased frequency, increased risk of UTI due to stasis.

13
Q

Name some musculoskeletal changes affecting the Tx of the pregnant Pt.

A

Sacral ligaments soften and relax. unsteady gait due to widening pelvis/abdomen.

14
Q

What accounts for most trauma among pregnant women?

A

Falls and blunt trauma.

15
Q

What equipment is needed to prepare for the pregnant trauma Pt?

A

Fetal monitor, emergency delivery pack, infant warmer.

16
Q

If your pregnant trauma Pt has retractions, what would you do?

A

Apply oxygen at 15L via non-rebreather mask.

17
Q

How would you treat a suspected case of supine hypotension syndrome who presents on a backboard?

A

Tilt the backboard at least 15 degrees with a hip wedge, or manually displace the uterus to the side.

18
Q

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?

A

Open airway with jaw thrust, insert OPA, ventilate via bag mask, prepare to intubate, request head CT, consider OG tube.

19
Q

What are the steps to confirming correct ETT placement?

A

Bilateral breath sounds, bilateral chest rise and fall, no gurgling over epigastrium, attach carbon dioxide detector and check level after 5-6 breaths.

20
Q

What are the weight ranges for classifying an individual as underweight/normal weight/overweight/obese?

A

BMI

21
Q

What type of MVA/injuries are more prevelant to bariatric patients?

A

More fatalities with frontal crashes. Pt more prone to head/thoracic/abdominal/extremity injury/fracture.

22
Q

When dosing analgesic meds for the bariatric Pt, is actual weight or ideal weight used to determine dosing?

A

Ideal body weight.

23
Q

What are 2 quick ways to check clear nasal drainage for the presence of CSF?

A

Place a drop on gauze and look for a halo, and test for glucose.
