What are two of the mechanisms from which a clot or thrombus arises and causes ischemic stroke?
Choose two answers
Oral anticoagulation Hypertension
Anoxic encephalopathy
Carotid stenosis
Atrial fibrillation
Glutamate toxicity
Correct Answer : C,D
A. Oral anticoagulation is a treatment to prevent clots and reduce the risk of ischemic stroke, not a mechanism that causes a clot to form.
B. Anoxic encephalopathy is brain damage due to a lack of oxygen, which can be a result of stroke but is not a cause of thrombus formation.
C. Carotid stenosis or the narrowing of the carotid arteries, can lead to the formation of clots that may travel to the brain and cause an ischemic stroke.
D. Atrial fibrillation is a heart rhythm disorder that can lead to the formation of blood clots in the heart. These clots can then travel to the brain and cause an ischemic stroke.
E. Glutamate toxicity refers to neuronal damage caused by excessive glutamate but is not a mechanism that leads to clot formation or ischemic stroke.

Correct Answer is C
Explanation
A. It is the one for which capillary membranes become extra permeable during inflammation, allowing certain proteins to move to tissues. This describes the interstitial fluid, not the intracellular fluid (ICF). During inflammation, the capillary membranes allow proteins to move into the tissues, which is part of the extracellular fluid (ECF) compartment.
B. It is located within the bloodstream. This describes the intravascular fluid, which is a part of the extracellular fluid (ECF) compartment, not the intracellular fluid (ICF).
C. It is located inside the cells. The intracellular fluid (ICF) is the fluid contained within the cells of the body, making up about two-thirds of the total body water.
D. It is the one containing hormones intended to balance red blood cell count. Hormones related to red blood cell production, such as erythropoietin, are not specific to the intracellular fluid compartment. This statement does not accurately describe the ICF.
Correct Answer is ["A","B","D"]
Explanation
A. Presence of fat embolisms: Fat embolisms can occur after fractures, particularly of long bones, and must be considered as they can lead to serious complications such as respiratory distress.
B. Pulse strength (0/4 to 4/4): Assessing pulse strength is crucial in musculoskeletal trauma to evaluate circulation and ensure there is no compromise to blood flow to the affected limb.
C. Age: While age can influence the healing process and susceptibility to injury, it is not a direct indicator of musculoskeletal trauma severity.
D. Circulation (capillary refill less than three seconds): Capillary refill time is a key assessment to evaluate circulation and the potential impact of musculoskeletal trauma on blood flow.
E. Potassium levels: Potassium levels are not directly related to musculoskeletal trauma assessment.
F. Level of vitamin D: Vitamin D levels do not provide immediate information relevant to acute musculoskeletal trauma.
