Correct Answer
B. Cerebral shock
Explanation
Cerebral shock is not a symptom of a brain tumor. Personality and behavioral changes, lethargy, inability to function, and even having no symptoms can be associated with brain tumors. However, cerebral shock, which refers to a sudden disruption in brain function, is not typically linked to brain tumors.
4.
A brain tumor produces widespread dysfunction
Correct Answer
B. False
Explanation
localized dysfunstion related to location
5.
The cause of a brain tumour is....
Correct Answer
D. Unknown
Explanation
The cause of a brain tumor is unknown. This means that medical researchers and professionals have not been able to determine the exact reason or factors that lead to the development of brain tumors. Despite extensive research, no specific cause or risk factors have been identified, making it difficult to prevent or predict the occurrence of brain tumors.
6.
The signs and symptoms of a brain tumour vary and are determined by its location and how aggressive it is
Correct Answer
A. True
Explanation
The given statement is true. Brain tumors can cause a range of signs and symptoms depending on their location and aggressiveness. Common symptoms may include headaches, seizures, changes in vision, difficulty with balance or coordination, memory problems, and personality changes. The specific symptoms experienced can vary greatly from person to person. The severity and progression of symptoms also depend on the type and size of the tumor. Therefore, it is important to consider the individual characteristics of each tumor when assessing its signs and symptoms.
7.
Seizures, nausea and vomiting can be signs and symptoms of a brain tumour?
Correct Answer
A. True
Explanation
Seizures, nausea, and vomiting can indeed be signs and symptoms of a brain tumor. Seizures occur when there is abnormal electrical activity in the brain, which can be caused by a tumor. Nausea and vomiting can result from increased pressure within the skull due to the tumor or from the tumor affecting the part of the brain responsible for regulating nausea and vomiting. These symptoms can vary depending on the size and location of the tumor, but they are potential indicators of a brain tumor.
8.
Treatment for brain tumours would include all but.....
Correct Answer
D. Improve mobility
Explanation
The treatment for brain tumors focuses on various aspects such as radiation and chemotherapy to target and eliminate cancer cells, surgery to remove the tumor, and energy conservation to help manage symptoms and conserve energy. However, improving mobility is not directly related to treating brain tumors. The primary focus is to remove or control the tumor and maintain overall brain function. Therefore, improving mobility would not be considered a part of the treatment plan for brain tumors.
9.
According to the notes, a CVA is defined as all but.....
Correct Answer
C. Neurons are replaceable
Explanation
The given answer states that a CVA (Cerebrovascular accident) does not involve neurons being replaceable. This means that when a CVA occurs, the damage caused to the brain's neurons is not reversible or replaceable. This is an important distinction because the loss of neurons can lead to long-term consequences and impairments in brain function.
10.
An embolism is a gradual process that develops over time
Correct Answer
B. False
Explanation
An embolism is not a gradual process that develops over time. It is a sudden blockage of a blood vessel by an embolus, which is a detached clot, air bubble, or foreign material that travels through the bloodstream and gets lodged in a smaller blood vessel, causing a sudden obstruction. This can lead to serious medical conditions and requires immediate medical attention.
11.
Build up of material in an artery is called
Correct Answer
D. Occlusion
Explanation
The build-up of material in an artery is called occlusion. This refers to the blockage or narrowing of the artery, which can restrict or completely stop the flow of blood. This build-up can be due to various factors such as plaque formation, blood clots, or inflammation. If left untreated, occlusion can lead to serious health issues such as heart attacks or strokes.
12.
Sudden rupture of an aneurysm is called
Correct Answer
E. Intracranial hemorrhage
Explanation
The sudden rupture of an aneurysm refers to the bursting of a weakened blood vessel in the brain, leading to bleeding within the skull. This condition is known as intracranial hemorrhage. Thrombosis refers to the formation of a blood clot within a blood vessel, while embolism refers to the obstruction of a blood vessel by a traveling blood clot. Intracranial pressure refers to the pressure inside the skull, and aphasia refers to a language disorder. However, neither of these terms specifically describes the sudden rupture of an aneurysm.
13.
An intracranial haemorrhage effects a single area of the brain
Correct Answer
B. False
Explanation
effects the whole area
14.
Concerning an occlusion, embolism, and intracranial haemorrhage - the only one with a slow onset is the occlusion
Correct Answer
A. True
Explanation
An occlusion refers to the blockage or obstruction of a blood vessel, which can occur in various parts of the body including the brain. Unlike embolism and intracranial hemorrhage, which typically have sudden and rapid onsets, an occlusion usually develops gradually over time. This slow onset is attributed to the gradual buildup of plaque or other substances that narrow the blood vessel and eventually lead to its complete blockage. Therefore, the statement that the only one with a slow onset among occlusion, embolism, and intracranial hemorrhage is occlusion is true.
15.
The one that causes the most damage is
Correct Answer
C. Intracranial hemorrhage
Explanation
Intracranial hemorrhage refers to bleeding that occurs within the skull, specifically in the brain. This condition can cause significant damage because the accumulation of blood puts pressure on the brain tissue, leading to compression and disruption of normal brain function. Depending on the location and extent of the hemorrhage, it can result in various neurological symptoms, including severe headaches, loss of consciousness, paralysis, or even death. Prompt medical intervention is crucial to prevent further damage and potentially save the patient's life.
16.
The cause of a CVA includes all of these but....
Correct Answer
A. Low blood sugar
Explanation
Low blood sugar, also known as hypoglycemia, is not a cause of a CVA (cerebrovascular accident) or stroke. A CVA is typically caused by factors such as increased blood pressure, cardiac disorders, weak blood vessels, and embolism. Low blood sugar may cause symptoms such as dizziness or confusion, but it is not a direct cause of a CVA.
17.
Flaccid, no reflexes, hypotonic, can last for 6 weeks
Correct Answer
B. Cerebral shock
Explanation
Cerebral shock refers to a state of temporary paralysis and loss of reflexes due to a sudden disruption in the blood supply to the brain. This can result in flaccidity, hypotonia (low muscle tone), and can last for up to 6 weeks. This condition is typically caused by trauma or injury to the brain, such as a concussion or severe head injury. It is important to note that cerebral shock is a temporary condition and with proper medical care and rehabilitation, the individual can gradually regain their normal muscle tone and reflexes.
18.
Right CVA
Correct Answer
C. Impulsive
Explanation
The correct answer is "impulsive" because the given symptoms of problems with speech, irritability, right hemiplegia, and increased frustration levels are all associated with impulsivity. Impulsivity refers to acting without thinking or considering the consequences, which can manifest in speech difficulties, irritability, and impulsive movements due to right hemiplegia. Additionally, increased frustration levels can contribute to impulsive behavior. Therefore, "impulsive" is the most fitting explanation for the given symptoms.
19.
A left CVA includes only
Correct Answer
D. Irritable
Explanation
A left CVA, or left cerebrovascular accident, refers to a stroke that occurs in the left side of the brain. This can result in various neurological symptoms. Irritability is a common symptom associated with left CVA, as the stroke can affect the emotional regulation centers in the brain. The damage to the left side of the brain can lead to increased irritability and difficulty in controlling emotions. Other symptoms mentioned in the question, such as poor judgement, problems with spatial relationships, and left hemiplegia (paralysis on the left side of the body), may also be present in a left CVA, but the specific symptom mentioned in the answer is irritability.
20.
A right CVA includes all but
Correct Answer
B. Problems with speech
Explanation
A right CVA (cerebrovascular accident) refers to a stroke that occurs in the right side of the brain. This type of stroke can lead to various symptoms, including impulsive behavior, poor judgement, problems with spatial relationships, and left hemiplegia (paralysis or weakness on the left side of the body). However, problems with speech are not typically associated with a right CVA.
21.
Sensory impairment
Correct Answer
C. Both
Explanation
The correct answer is "both" because sensory impairment can occur in both left and right CVA (cerebrovascular accident) cases. A CVA, also known as a stroke, can affect different areas of the brain depending on whether it is a left or right hemisphere stroke. Sensory impairment refers to the loss or reduction of sensation, such as touch, temperature, or proprioception. Both left and right CVAs can result in sensory deficits, depending on the specific location and extent of the brain damage.
22.
Problems with speech
Correct Answer
A. Left CVA
Explanation
The correct answer is left CVA. CVA stands for cerebrovascular accident, which is commonly known as a stroke. A left CVA refers to a stroke that occurs in the left side of the brain. One of the common symptoms of a left CVA is problems with speech, such as difficulty speaking, slurred speech, or inability to find the right words. This occurs because the left side of the brain is responsible for language and speech production.
23.
Confusion
Correct Answer
C. Both
Explanation
The correct answer is both because the question is asking about the occurrence of confusion in both left CVA (cerebrovascular accident) and right CVA. This means that confusion can be a symptom or outcome of both left and right CVAs.
24.
Personality changes
Correct Answer
C. Both
Explanation
The correct answer is "both." This suggests that personality changes can occur in individuals who have experienced either a left CVA or a right CVA. A cerebrovascular accident (CVA), also known as a stroke, can cause damage to different areas of the brain depending on whether it occurs on the left or right side. Personality changes can manifest as alterations in behavior, mood, and cognition. Both left and right CVAs have the potential to impact these aspects of a person's personality, leading to changes in their overall demeanor and character.
25.
Problems with spatial relationships
Correct Answer
B. Right CVA
Explanation
Right CVA refers to a right cerebrovascular accident, which is a medical condition that occurs when there is a sudden disruption of blood supply to the brain, specifically in the right hemisphere. This can result in various neurological deficits, including problems with spatial relationships. Spatial relationships refer to the ability to perceive and understand the position, size, and distance between objects. Therefore, it is likely that a person with a right CVA may experience difficulties in perceiving and understanding spatial relationships.
26.
Contralateral muscle weakness or paralysis
Correct Answer
A. Anterior cerebral artery
Explanation
The anterior cerebral artery supplies blood to the frontal lobes and the medial surface of the brain. Damage to this artery can result in contralateral muscle weakness or paralysis, meaning that the weakness or paralysis will affect the opposite side of the body from where the damage occurred. This is because the motor pathways in the brain cross over to the opposite side of the body. Therefore, if there is damage to the anterior cerebral artery on the right side of the brain, it will result in weakness or paralysis on the left side of the body.
27.
Global apphasia
Correct Answer
B. Middle cerebral artery
Explanation
The middle cerebral artery is responsible for supplying blood to the lateral surface of the brain, including the areas involved in language processing. Global aphasia is a type of language disorder that affects all aspects of language production and comprehension. Since the middle cerebral artery supplies blood to the language areas of the brain, damage to this artery can result in global aphasia.
28.
Middle cerebral artery includes
Correct Answer
C. Contralateral paralysis and sensory loss of UE and body
Explanation
The middle cerebral artery is a major blood vessel in the brain that supplies blood to various areas, including the motor and sensory regions. When there is a blockage or damage to this artery, it can lead to contralateral paralysis and sensory loss of the upper extremities (UE) and the body. This means that the paralysis and sensory loss occur on the opposite side of the body from where the damage to the artery is located. This can result in difficulties with movement and sensation in the affected limbs and body. The other symptoms mentioned in the question, such as vision loss, sensory loss in the legs, and problems with problem-solving and verbal and motor responses, are not specifically associated with the middle cerebral artery.
29.
Which one does not belong concerning posterior cerebral artery
Correct Answer
B. Contralateral muscle weakness or paralysis
Explanation
The posterior cerebral artery supplies blood to the occipital lobe of the brain, which is responsible for vision. Therefore, the symptom that does not belong concerning the posterior cerebral artery is contralateral muscle weakness or paralysis. This symptom is more commonly associated with damage to the motor cortex or the corticospinal tract, which are supplied by other arteries.
30.
Loss of vision, aphasia, loss of pain and temperature sensation, loss of proprioception, cortical blindness, ataxia
Correct Answer
C. Posterior cerebral artery
Explanation
The symptoms listed, such as loss of vision, aphasia, loss of pain and temperature sensation, loss of proprioception, cortical blindness, and ataxia, are consistent with a stroke or damage to the posterior cerebral artery. The posterior cerebral artery supplies blood to the occipital lobe, which is responsible for vision, as well as other areas involved in language, sensation, and coordination. Damage to this artery can result in various neurological deficits, including those mentioned.
31.
Contralateral muscle weakness or paralysis, sensory loss in legs, confusion, lose the ability to problem solve, personality changes, delay in verbal and motor responses
Correct Answer
A. Anterior cerebral artery
Explanation
The symptoms described in the question, such as contralateral muscle weakness or paralysis, sensory loss in legs, confusion, and personality changes, are consistent with a stroke affecting the anterior cerebral artery. This artery supplies blood to the frontal lobes of the brain, which are responsible for motor control, sensory perception, and higher cognitive functions. Therefore, damage to this artery can result in the mentioned symptoms.
