A nurse is caring for a client with a closed skull injury who has an intracranial pressure (ICP) reading consistently over 20 mmHg, According to the MonroeKellie Doctrine, If Intracranial pressure continues to Increase, what will occur? Select All that Apply.
A. Fracture of the skull
Fracture of the skull is not a consequence of increased ICP, but rather a possible cause of it. A fracture can allow blood or cerebrospinal fluid (CSF) to leak into the cranial cavity and increase the pressure inside the skull. This is an incorrect choice.
B. Ischemia
Ischemia is a condition where the blood supply to a tissue or organ is reduced or blocked, resulting in oxygen deprivation and tissue damage or death. Increased ICP can cause ischemia by compressing blood vessels and reducing cerebral perfusion pressure (CPP), which is the difference between mean arterial pressure (MAP) and ICP. CPP must be maintained above 60mmHg to ensure adequate blood flow to the brain. This is a correct choice.
C. Hypotension
Hypotension is a condition where the blood pressure is abnormally low, which can impair organ function and perfusion. Increased ICP can cause hypotension by stimulating the vagus nerve, which slows down the heart rate and lowers the cardiac output and MAP. This reduces the CPP and increases the risk of ischemia. This is a correct choice.
D. Hyperventilation
Hyperventilation is a condition where the breathing rate and depth are increased, resulting in lower levels of carbon dioxide (CO2) in the blood. Increased ICP can cause hyperventilation by stimulating the respiratory center in the brainstem, which tries to lower the CO2 levels and increase the pH of the blood. This causes cerebral vasoconstriction and reduces ICP temporarily, but also reduces CPP and increases the risk of ischemia. This is a correct choice.
E. Increase in Glasgow Coma Score

A nurse is providing education to a group of older adults about the risk of stroke. Which selections made by the group indicate an understanding of the teaching? Select All that Apply (Select All that Apply.)
A. Changes in face, arm movement, or speech could indicate signs of a stroke.
Changes in face, arm movement, or speech could indicate signs of a stroke. This is a correct choice. These are some of the common signs of a stroke that can be detected using the FAST acronym (Face drooping, Arm weakness, Speech difficulty, Time to call 911). Recognizing these signs and seeking immediate medical attention can improve the chances of survival and recovery from a stroke.
B. Hypotension, dehydration, and age are risk factors for stroke.
Hypotension, dehydration, and age are risk factors for stroke. This is an incorrect choice.Hypotension (low blood pressure) is not a risk factor for stroke; rather, hypertension (high blood pressure) is one of the major risk factors for stroke. Dehydration can cause hypotension, which can lead to dizziness and fainting, but not necessarily stroke. Age is a nonmodifiable risk factor for stroke, meaning that it cannot be changed or prevented. Older adults have a higher risk of stroke than younger adults, but this does not mean that younger adults are immune to stroke.
C. Everyone should take lowdose aspirin to reduce stroke risks
Everyone should take lowdose aspirin to reduce stroke risks. This is an incorrect choice.Aspirin is a medication that can prevent blood clots from forming and reduce the risk of ischemic stroke (caused by a blocked artery in the brain). However, aspirin is not suitable for everyone and can have side effects such as bleeding and stomach ulcers. Aspirin should only be taken under the guidance of a health care provider who can weigh the benefits and risks for eachindividual.
D. Annual endarterectomy screening exams are essential.
Annual endarterectomy screening exams are essential. This is an incorrect choice.Endarterectomy is a surgical procedure that removes plaque from the carotid arteries (the main arteries that supply blood to the brain). This can prevent or treat carotid artery disease, which is a risk factor for ischemic stroke. However, endarterectomy is not a screening exam; it is aninvasive treatment that has its own risks and complications. Endarterectomy is only recommended for people who have severe narrowing of the carotid arteries or who have had symptoms of a transient ischemic attack (TIA) or minor stroke.
E. Avoiding excess sodium, limiting alcohol, and exercising regularly decrease risks for
A nurse is monitoring the vitals of a client who has a traumatic brain injury. Which of the following indicate that the client is in stage 3 of increased Intracranial pressure? Select all that apply
(Select All that Apply.)
A. asystole
Asystole is incorrect because it is a cardiac arrest, not a sign of increased intracranial pressure (ICP).
B. hypotension
Hypotension is correct because it indicates that the brain is losing its ability to regulate blood pressure due to increased ICP.
C. widening pulse pressure
Widening pulse pressure is correct because it reflects the difference between systolic and diastolic blood pressure, which increases as the brain tries to maintain cerebral perfusion despite increased ICP.
D. bradycardia and bounding pulse
Bradycardia and bounding pulse are correct because they are signs of Cushing's triad, a classic manifestation of increased ICP that results from increased vagal stimulation and decreased sympathetic activity.
E. uneven breathing
A nurse in the emergency room is assessing a client who was brought in following a seizure. The nurse suspects the client may have meningococcal meningitis. Assessment findings include nuchal rigidity and a petechial rash. After Implementing droplet precautions, which of the following actions should the nurse initiate next?
A. Complete a vascular assessment.
Although meningococcal meningitis can lead to complications such as septicemia, which affects vascular status, assessing cranial nerves is more immediately pertinent. Identifying neurological deficits can provide crucial information about the extent and location of meningitis-related brain involvement.
B. Assess the cranial nerves
Meningococcal meningitis can affect the central nervous system, leading to cranial nerve involvement. Assessing the cranial nerves helps to identify any neurological deficits early, which is crucial for guiding treatment and monitoring progression.
C. Decrease environmental stimuli.
While this is important for managing a patient with meningitis to prevent further neurological irritation, it is not as immediate a priority as assessing cranial nerve function to detect any neurological impairment.
D. Administer an antipyretic.
Fever management is important, but it is not the next immediate priority after initiating droplet precautions. Assessing cranial nerves provides vital information about the patient's neurological status, which directly impacts immediate clinical decisions.
