Q

Rules for lightning

A

-wait at least 30
minutes after the last sound of thunder or lightning
flash before resuming an activity or returning out-
doors
-By
the time the flash-to-bang count approaches 30 seconds (or
is less than 30 seconds), all individuals should already be
inside or should immediately seek a safe structure or
location

Q

What is the flash-to-bang method?

A

the observer begins counting when a lightning flash is sighted.
Counting is stopped when the associated bang (thunder) is
heard. Divide this count by 5 to determine the distance to
the lightning flash (in miles). For example, a flash-to-bang
count of 30 seconds equates to a distance of 6 miles

Q

Describe axillary nerve and axillary nerve injury

A

The Axillary nerve winds around the surgical neck of the humerus after passing to the posterior aspect of the arm through the quadrangular space. A traction injury can occur with a traumatic anterior dislocation. (about 30% experience mostly mild neuropraxic lesions with less than 5% experiencing significant damage.
Weakness in shoulder abduction and external rotation along with decreased sensation over the lateral side of the proximal part of the arm. The patient may have already recovered full neurological function at 4 weeks.

Q

Describe zygomatic fracture

A

The zygomatic bone is the second most commonly fractured structure in the face. Common cause is usually blunt trauma to the cheek. Signs and symptoms include numbness to the cheek, infraorbital region and upper teeth on the injured side; eyelid swelling; inability to close mouth properly; swelling and ecchymosis, flattened cheekbone.

Q

What imaging modality is most appropriate for use with an athlete with acute concussive symptoms?

A

A CT scan is indicated if a focal injury such as an acute subdural or epidural bleed is suspected; this study easily demonstrates acute blood collection and skull fracture.  While this would be a rarity, if is the image of choice in this population.

Typically none

51
Q

DOMS symptoms

A

-dull, diffuse pain and tenderness;
-stiffness;
-swelling;
-decreased strength of the exercised muscle.
These signs and symptoms typically last 1 to 4 days after the exercise bout.

52
Q

What causes Acute Exertional rhabdomyolysis

A

caused by a skeletal muscle injury that results in the release of myoglobin and other cellular contents into the circulatory system

53
Q

Describe Trigeminal Nerve

A

fifth cranial nerve (CN V) and the largest of the cranial nerves. Its primary function is to provide sensory innervation to the face and is divided into three main branches. The different branches are the ophthalmic (V1), maxillary (V2), and mandibular (V3) nerves

54
Q

Describe Facial Nerve

A

7th cranial nerve and
- control facial movement and expression.
-involved in taste to the anterior 2/3 of the tongue and producing tears (lacrimal gland)

55
Q

What should people with sickle cell trait avoid?

A

people with sickle cell disease should be active, but intense activities that cause you to become seriously out of breath are best avoided. avoid alcohol and smoking – alcohol can cause you to become dehydrated and smoking can trigger a serious lung condition called acute chest syndrome.

56
Q

Symptoms of acute exertion rhabdomyolysis

A

-Muscle aches and pains out of proportion with the amount of exercise.
-Muscle cramping, swelling, and/or weakness.
-Stiffness and decreased range of motion.
-Rapid heart rate.
-Nausea or vomiting.
-Headache.
-Confusion and disorientation.
-Tea or Coca-Cola colored urine.
-intense workout (particularly with eccentrics),
–bilateral pain,
-marked point tenderness.

57
Q

Acute exertion rhabdomyolysis prevention

A

-hydration, drinking plenty of fluids especially in preparation for exercise. By consuming plenty of fluids, it will dilute the concentration of myoglobin to aid the kidney in clearing the bloodstream
-heat acclimatization

58
Q

What is the recommended mode and frequency of exercise for individuals with Type I and II diabetes?

A

Patients with diabetes mellitus should have 5 or more days (a minimum of 150 minutes) of aerobic exercise weekly and 3 days of resistance training weekly. Evidence for optimal frequency continues to evolve.
recent studies show that resistance exercise improves insulin sensitivity similar to that of aerobic exercise

59
Q

Sickle Cell Collapse presentation:

A

-often occurs within the first half hour onfield, as during initial windsprints.
Core temperature is not greatly elevated.
-The athlete initially will still be conscious and able to talk
-complains of muscular pain, however this is not to be confused with muscle cramping.
Exertional sickling is a medical emergency and requires immediate treatment.
TREATMENT administration of oxygen (151 pm) is the gold standard, as well as calling 911 if vital signs are declining

60
Q

Primary source of articular cartilage

A

Type 2

61
Q

What test is best to test anterior drawer of ACL?

A

anterior bundle test: Performing this test at 90 degrees of knee flexion will stress the anteriomedialbundle, which is most taut in this range.

62
Q

most common type of arrhythmia preceding death

A

V fib

63
Q

Sickle Cell Trait treatment

A

Stopping when athlete has cramping, fatigue, or dyspnea

64
Q

Signs of Sickle Cell Trait Collapse

A

Exercise collapse with sickle cell
most common w/all-out exertion
Often occurs within 30 min of workout

Collapse is medical emergency, administer O2 if necessary

65
Q

How athlete with Marfan;s managed?

A

Echo every 6 months monitor size of aorta, preventing complications such as decreasing BP to
prevent enlargement of aorta
No collision sports or strenuous exercises ex. NO weight lifting

66
Q

What does Marfan’s syndrome affect

A

Disorder of connective tissue
aortic arch dilation (can rupture
aorta)
