Q

What are the classic signs for a urethral injury?

A

Look for blood at urethral meatus, high riding “blamable” prostate, or absence of palpable prostate. If signs of injury, perform retrograde urethrogram to rule out injury prior to Foley cather placement.

1-4 points in Eye Opening category of GCS
Spontaneous = 4 To voice = 3 To pain = 2 None = 1
26
1-5 points in Verbal Response category of GCS
``` Oriented = 5 Confused = 4 Inappropriate words = 3 Incomprehensible = 2 None = 1 ```
27
1-6 points in Motor response category of GCS
``` Obeys commands = 6 Localizes pain = 5 Withdraws from pain = 4 Flexion with pain = 3 Extension with pain = 2 None = 1 ```
28
While the head of an unconscious patient is turned, a patient's eyes follow the movement, rather than being fixed at a point in space. This is suggestive of which injuries?
Vestibular, cranial nerve, pontine, or medullary.
29
Important part of treatment in neck trauma (penetrating injury)
Prophylactic abx due to increased risk of contamination by oropharyngeal flora.
30
Anatomic differences in post-traumatic pregnant patient
IVC compression by uterus makes pregnant women more susceptiblle to poor CO following injury. Decreased risk of GI injury from lower and trauma because of superior displacement of bowel by the uterus (but greater risk of GI injury from upper abdominal or chest trauma)
31
Who gets examined first -- mother or fetus?
Mother
32
Describe superficial partial thickness burn
FIRST DEGREE. It is painful. There is erythema and BLISTERS. Capillary refill is INTACT.
33
Describe signs and symptoms of second degree burn
Painful with blisters. Does NOT blanch with pressure.
34
%BSA of palm
1%
35
What is unique to mgmt of electrical burn patients as compared to heat burn patients
Aggressive IVF to prevent myoglobinuria, renal failure n and acidosis in the face of muscle necrosis. High index of suspicion for compartment syndrome. Obtain an EKG and monitor for dysrhythmias.
36
When should a burn patient be transferred to a burn center
``` Full thickness burn >5% BSA Partial thickness >10% BSA Any burn to face, genitals, perineum, or major joints Circumferential burns Electrical or lightning injury Inhalation injury Fracture or other trauma assoc with burn Pre-existing medical problems (e.g. DM, sickle cell) or special psychosocial or rehab needs. ```
37
5 Common life threatening complications in pt with substantial burns
``` Hypovolemia -- > shock Sepsis due to PNA or pseudomonas Inhalation Cardiac dysrhythmia Renal failure ```
38
In heat stroke, what is the best method of cooling
Via evaporation, so continuous fanning and spraying of skin with lukewarm water
39
Treatment for black widow spider bite with mild skin reactions
Tetanus toxoid ppx
40
Treatment for black widow spider bite with necrotic center >2 cm
5-7 days corticosteroids
41
Abx if signs of infection in black widow spider bite
Erythromycin
42
How can we possibly reduce extent of local necrosis in black widow spider bite
Consider dapsone due to leukocyte inhibitory properties. But obviously r/o G6PD deficiency first due to risk of hemolytic anemia
43
If systemic symptoms after black widow spider bite ..
``` Calcium gluconate q2 hrs for muscle pain Benzos for AMS Steroids Nitrates for HTn Methocarbamol for muscle spasm Analgesia with acetaminophen +/- opioids Antivenom ideally within 30 min ```
44
Higher likelihood of infection after dog/cat bite if ..
``` Cat bite Eats wet food Presents >6-12 hrs post-bite Presents >12-24 hrs post-bite to face Immunocompromised host ```
45
When do pts get rabies ppx after animal bite
If animal cannot be observed for 10 days or if animal is suspected to be rapid
46
Abx choices for animal bites
Amp/sulbactam then Amox/clav Clinda + FQ Clinda + Bactrim DS
47
Anticholinergic sx and antidote
Hot as a hare, dry as a bone, red as a beet, blind as a bat (mydriasis, cycloplegia) and mad as a hatter, bloated as a toad, tachycardia, decreased or absent BS. Antidote: pralidoxime, atropine
48
S&S of organophosphate poisoning
Diarrhea, urination, miosis, bronchospasm, bradycardia, emesis and excitation of skeletal muscle, lacrimation, sweating, salivation, and abdominal cramping.
49
Describe phases of iron toxicity
GI phase 30 min - 6 hrs post ingestion Latent/stable phase 6-24 hrs post ingestion Shock and metabolic acidosis 6-72 hrs post ingestion Hepatotoxicity/hepatic necrosis 12-96 hrs post ingestion Bowel obstruction 2-8 wks post ingestion
50
Treatments tO NOT USE **** for ingestion of alkali plumbing liquid
Ipecac, a neutraliz agent which will improve nothing but amy result in thermal injury NG tube which may lead to perf or emesis of caustic
51
Surveillance EGD after ingestion of alkali plumbing liquid
Beginning 15-20 yrs after ingestion at interval of q1-3 yrs to evaluate for esophageal SCC
52
Almond scented breath
Cyanide poisoning
53
Ingestion can cause delayed onset parkinsons
Cyanide ingestion as basal ganglia is sensitive to cyanide
54
Accelerated junctional rhythm or bidirectional ventricular tachycardia suggests?
Digoxin toxicity until proven otherwise
55
Characteristic EKG changes in digoxin at therapeutic levels
Prolonged PR interval | "scooping" of ST segments
56
Most freq vital sign abnormality in digoxin toxicity
Bradycardia. Atrial tach with AV block is less common.
57
How do we indicate severity of digoxin toxicity?
Hyperkalemia.
58
When should hyperkalemia be treated in cases of dig toxicity?
Only if its causing EKG disturabnces. Avoid calcium which can worsen intracellular hyperkalemia.
59
Acid base disturbance in aspirin OD
Resp alkalosis from hyperventilation THEN a mixed res alkalosis and metabolic acidosis with elevated anion gap.
60
Why do pts that OD on aspirin often get tachypneic?
ASA stimulates medullary respiratory center
61
Why do pts that OD on aspirin often get hyperthermic?
ASA uncouples mitochondrial oxidative phosphorylation.
62
MCC of acute hemolytic transfusion reaction
ABO incompatibility
63
Treatment of chronic mesenteric iscehmia
Bypass, angioplasty
64
S&S of chronic mesenteric ischemia
"intestinal angina" Dull crampy post prandial epigastric pain within first hour after eating then subsiding over 2 hours Weight los d/t food aversion to avoid postprandial pain N/V early satiety Abdominal bruit in 50%
65
When is greatest risk for postop MI?
48 hours post op
66
What is recommended perioperatively for pts with known CAD?
Peri op beta blockers and telemetry monitoring
67
