Choice A rationale: The nurse should prepare to administer tissue plasminogen activator (tPA). This medication is used to dissolve blood clots that have formed in the blood vessels of the brain. The client’s CT scan shows a large area of decreased attenuation in the left hemisphere, which is indicative of a stroke. The administration of tPA is time-sensitive and should be initiated as soon as possible after the onset of symptoms if there is no evidence of hemorrhage on the CT scan.

Choice B rationale: Positioning the client on his right side is not necessarily beneficial in this situation. The client is experiencing symptoms of a stroke, and positioning will not alleviate these symptoms. It is more important to focus on interventions that can potentially reverse the effects of the stroke, such as the administration of tPA.

Choice C rationale: There is no indication that the client requires a bolus of 50% dextrose. The client’s blood glucose levels are within normal limits, and hypoglycemia is not a concern at this time. Administering a bolus of 50% dextrose without indication could potentially lead to hyperglycemia.

Choice D rationale: The nurse should anticipate the need for endotracheal intubation. The client’s condition is deteriorating, and he is now unresponsive to verbal stimuli and only responds to painful stimuli. This indicates a decreased level of consciousness, which can compromise the client’s airway. Endotracheal intubation may be necessary to protect the client’s airway and ensure adequate ventilation.

Choice E rationale: The nurse should prepare to administer antihypertensive medication. The client’s blood pressure is significantly elevated, which can further exacerbate the damage caused by a stroke. Antihypertensive medication can help to lower the client’s blood pressure and reduce the risk of further complications.

Choice F rationale: The nurse should use a calm and reassuring approach when interacting with the client. This can help to reduce anxiety and promote a sense of safety. It is important to remember that the client may be scared and confused due to his symptoms, and a calm and reassuring approach can help to alleviate these feelings.

Choice G rationale: Restricting all fluids and sodium intake is not indicated in this situation. While fluid and sodium balance is important in stroke patients, there is no indication that the client is fluid overloaded or has a condition that would require sodium restriction. Furthermore, the client has been prescribed IV fluids, indicating that fluid restriction is not appropriate at this time.

Choice A rationale
Osmotic cerebral edema is a condition where water moves from the blood vessels into the brain due to changes in the concentration of particles in the blood. However, this is not the primary cause of cerebral edema in meningitis.
Choice B rationale

While inflammation can contribute to cerebral edema, it is not specific to the brain and does not affect the brain the most. In meningitis, the inflammation is primarily in the meninges, the membranes that cover the brain, and not the whole body.
Choice C rationale
Cerebrospinal fluid (CSF) does flow from the intraventricular space to the interstitial area of the brain, but this is a normal process and does not cause cerebral edema. In meningitis, the inflammation of the meninges can disrupt the normal flow and absorption of CSF, leading to an accumulation of fluid and increased intracranial pressure.
Choice D rationale
In meningitis, the inflammation and immune response to the infection can lead to an increase in the permeability of the blood-brain barrier. This allows fluid and immune cells to enter the brain tissue, leading to cerebral edema. Additionally, the by-products of the pathogen that causes meningitis can directly damage the brain tissue and contribute to the edema.

Choice A rationale
Cancer pain is usually associated with the growth of a tumor or the side effects of cancer treatment. Phantom limb pain is not related to cancer.
Choice B rationale
Phantom limb pain is considered a type of neuropathic pain. This is because it is associated with nerve damage or malfunctioning nerves in the area where the limb was amputated.
Choice C rationale
Chronic pain is a broad term that refers to any pain that lasts for more than 12 weeks. While phantom limb pain can become chronic, this term does not specifically describe the type of pain experienced in phantom limb syndrome.
Choice D rationale
Acute pain is a type of pain that comes on suddenly and has a specific cause, usually related to tissue damage. Phantom limb pain is not considered acute pain because it is not related to new tissue damage.

Choice A rationale
While a stiff neck can be a symptom of a cerebral aneurysm, it is not a definitive sign. A stiff neck is more commonly associated with conditions like meningitis.
Choice B rationale
Most cerebral aneurysms do not cause symptoms until they rupture or become very large. Therefore, a person with a cerebral aneurysm typically will have no symptoms.
Choice C rationale
Seizures can occur if a cerebral aneurysm ruptures and causes bleeding in the brain. However, seizures are not a common symptom of unruptured cerebral aneurysms.
Choice D rationale
Nausea and vomiting can occur if a cerebral aneurysm ruptures and causes a sudden increase in intracranial pressure. However, these are not typical symptoms of an unruptured cerebral aneurysm.

Choice A rationale
While emotional disorders and acute pain can occur after a traumatic brain injury (TBI), they are not considered secondary conditions. These are more immediate and direct results of the injury.
Choice B rationale
Loss of sensation and cognition difficulties are common secondary conditions that can develop after a TBI. These can be due to damage to specific areas of the brain during the injury.
Choice C rationale
Body dysmorphia and neurofibrillary tangles are not typically associated with TBI. Body dysmorphia is a psychological disorder, and neurofibrillary tangles are associated with neurodegenerative diseases like Alzheimer’s.
Choice D rationale
Decreased appetite and a lack of sleep can occur after a TBI, but they are more likely to be symptoms rather than secondary conditions. Secondary conditions are typically more long- term and are a result of changes in the brain after the injury.

Choice A rationale
While improved rehabilitation outcomes and temporary behavior changes can occur after a neurological injury, they are not typically considered psychosocial changes. Psychosocial changes often involve alterations in the way individuals perceive, interact with, and navigate their social environments.
Choice B rationale
Improved mood stability and temper control are not typically associated with the aftermath of a neurological injury. In fact, individuals may experience mood swings, irritability, and difficulties with emotional regulation.
Choice C rationale
Changes to social cognition and challenges to inhibitory control are indeed possible psychosocial changes a client might have after sustaining a neurological injury. Social cognition involves understanding and interpreting social cues, which can be affected by brain injury.
Challenges to inhibitory control can lead to impulsive behavior and difficulties in social situations.
Choice D rationale
While a sense of purpose, improved motivation, and stable relationships can be part of a successful recovery process, they are not typically direct outcomes of a neurological injury. In

fact, relationships may be strained and motivation can be affected due to the physical and emotional challenges associated with such an injury.

Choice A rationale
While a CT angiogram can indeed reveal fractures within the skull or spine, this is not its primary purpose in the context of a subarachnoid hemorrhage. The main goal is to visualize the blood vessels in the brain.
Choice B rationale
A CT angiogram does not primarily reveal overproduction of cerebrospinal fluid (CSF). It is used to visualize the blood vessels in the brain.
Choice C rationale
While a CT angiogram can show areas of edema within the brain tissue, this is not its main purpose in the context of a subarachnoid hemorrhage. The primary goal is to visualize the blood vessels in the brain.

Choice D rationale
A CT angiogram can indeed reveal decreased blood flow related to vasospasm in the context of a subarachnoid hemorrhage. Vasospasm is a condition in which blood vessels spasm, leading to vasoconstriction. This can reduce blood flow to the brain, which can be visualized on a CT angiogram.

Choice A rationale
A patient reporting a burning sensation is a subjective sign of pain. It relies on the patient’s personal experience and verbal report.
Choice B rationale
A patient grimacing when they move is an objective sign of pain. It is observable and does not rely on the patient’s verbal report.
Choice C rationale

A patient rating their pain as an 8 on a scale of 0 to 10 is a subjective sign of pain. It relies on the patient’s personal experience and verbal report.
Choice D rationale
A patient stating the pain is located in their abdomen is a subjective sign of pain. It relies on the patient’s personal experience and verbal report.

Choice A rationale
Cushing’s Triad, which includes bradycardia (low heart rate), irregular respiration, and widened pulse pressure, is a nervous system response that could prevent brainstem ischemia. Brainstem ischemia is a condition where there is insufficient blood flow to the brainstem, which can lead to cell death.
Choice B rationale

While tachycardia (high heart rate) is a serious condition, it is not typically prevented by Cushing’s Triad.
Choice C rationale
Agonal breathing, which is characterized by gasping, labored breathing, particularly when lying flat, is not typically prevented by Cushing’s Triad.
Choice D rationale
Chest pain is not typically prevented by Cushing’s Triad. Cushing’s Triad is a response to increased intracranial pressure, not a cardiac condition.

Choice A rationale
Nicardipine is a calcium channel blocker used to treat high blood pressure. While it can be used in the management of subarachnoid hemorrhage, it is not primarily used to decrease intracranial pressure.
Choice B rationale

Dopamine is a type of medication used to treat certain conditions such as low blood pressure, heart failure, and Parkinson’s disease. It is not typically used to decrease intracranial pressure in the context of a subarachnoid hemorrhage.
Choice C rationale
Mannitol is a type of medication that is used to decrease intracranial pressure. It works by drawing fluid out of the brain to help reduce swelling.
Choice D rationale
Phenytoin is a medication used to control seizures. While it can be used in the management of subarachnoid hemorrhage, it is not primarily used to decrease intracranial pressure. Migraine Explore
