Which of the following is recommended therapy for a CVT?
A) anticoagulation therapy
B) antiplatelet therapy
C) immunosuppression
D) steroids

D
Mannitol is given to increase serum osmality and lower cerebral edema. This is
considered first-line treatment for an increased ICP. CSF drainage may be used if
ICP remains elevated following administrations of the osmotic diuretic.
Phenobarbital coma and mild hyperventilation are considered third-tier
interventions
, A
CVT is a thrombosis and is managed with anticoagulation therapy (heparin,
LMWH, Warfarin-Coumadin) even if hemorrhage is present on CT scan.
Antiplatelet therapy is not as effective as anticoagulation therapy in managing
a venous thrombus. Immunosuppression and steroids are not recommended
therapy for CVT
B
Maintaining glucose btwn 140-180mg/dL prevents potential complications of
hyperglycemia and hypoglycemia. Strict glycemic control of 80-120mg/dL or
maintaining <130mg/dL is not recommended d/t the potential hypoglycemia
episodes. Allowing BG to increase to 250mg/dL before treatment can increase
ischemic injury
A
Rhabdomyolysis is a potential complication of a statin. Other potential
complications include cardiomyopathy, HA, and elevated liver enzymes. Increased
bleeding is a potential complication not Venous thrombosis. N/V and AKI are not
considered complications of statins

Where in the brain are the dural sinuses located?
A) epidural space
B) subdural space
,C) subarachnoid space
D) subpial space

B
The L hemisphere is usually the dominant hemisphere responsible for
communication. It contains the Broca speech center and Wernicke's area in the
majority of the population. L hemispheric strokes are more likely to involve a loss of
communication or aphasia

bleeding is a potential complication not Venous thrombosis. N/V and AKI are not
considered complications of statins
B
The subdural space is located btwn the dura mater and the arachnoid layer.
The venous sinuses are located in the subdural space. The CSF circulates in the
subarachnoid space, and the epidural is a potential space with arterial supply.
There is not a subpial space.
D
The recommendation to reduce the hypertension RF of a stroke in a non-diabetic
hypertensive pt is to maintain BP <140/90. A BP too low in a chronic hypertensive pt
can cause hypoperfusion to the brain. Diabetic pts may have the goal to maintain
their BP <130/80 d/t their associated major RF for strokes.

A pt is brought to the ER after falling on the pier and hitting his head.
He is currently on ASA, furosemide (lasix) and captopril (Capoten).
Upon admission, he complains of a HA and dizziness. Within 15mins of
being in ED he becomes unresponsive. Which of the following
interventions is the priority of care.
A) intubate and ventilate pt
B) Obtain a stat CT scan
C) Administer mannitol
D) Insert ICP monitor

A
The anterior cerebral artery supplies blood to the medial portion of the frontal
lobe. A portion of the motor strip controls the LE while the MCA supplies blood to
the portion that controls the upper extremities and face. The PCA supplies blood to
the occipital lobe and basilar artery to the brain stem.
B
An INR 2-3 (goal 2.5) is recommended for primary prevention of cardioembolic
stroke in afib when treated with warfarin. Higher INR (3.5-4.2) in secondary stroke
