The nurse notes that a client has ataxia. Which test does the nurse use to gain more information about this client's gait?

Choice A reason: A public health nurse is a nurse who works to improve the health and well-being of populations and communities, not specific workplaces. A public health nurse may focus on disease prevention, health promotion, environmental health, or emergency preparedness.

Choice B reason: A community nurse specialist is a nurse who has advanced education and training in a specific area of nursing practice, such as gerontology, oncology, or mental health. A community nurse specialist may work in various settings, such as hospitals, clinics, or schools, to provide specialized care and education to clients and families.

Choice C reason: A nurse clinician is a nurse who has expertise in clinical practice, research, and education. A nurse clinician may work in academic or clinical settings, such as universities, hospitals, or research centers, to develop and implement evidence-based practices and policies.

Choice D reason: An occupational health nurse is a nurse who works to protect and promote the health and safety of workers in various industries, such as manufacturing, mining, or construction. An occupational health nurse may provide services such as health assessment, injury prevention, emergency response, or wellness programs.

Choice A reason: Hypertension is a manifestation of increased intracranial pressure, as it reflects the body's attempt to maintain adequate cerebral perfusion pressure (CPP) and blood flow to the brain. CPP is the difference between the mean arterial pressure (MAP) and the intracranial pressure (ICP). When ICP rises, MAP must also rise to keep CPP constant and prevent cerebral ischemia. Hypertension is part of the Cushing's triad, which is a classic sign of increased ICP that also includes bradycardia and irregular respirations.

Choice B reason: Tinnitus is not a manifestation of increased intracranial pressure, as it does not affect the auditory system. Tinnitus is a ringing, buzzing, or hissing sound in the ears that can be caused by various factors, such as ear infections, noise exposure, medications, or aging. Tinnitus may be associated with other neurological conditions, such as Meniere's disease, acoustic neuroma, or multiple sclerosis, but not with increased ICP.

Choice C reason: Hypotension is not a manifestation of increased intracranial pressure, as it indicates a decrease in MAP and CPP, which can lead to cerebral ischemia and infarction. Hypotension can be caused by various factors, such as blood loss, dehydration, shock, or medications. Hypotension may worsen the outcome of increased ICP by reducing the oxygen and nutrient delivery to the brain.

Choice D reason: Tachycardia is not a manifestation of increased intracranial pressure, as it contradicts Cushing's triad. Tachycardia is an increase in heart rate that can be caused by various factors, such as anxiety, pain, fever, dehydration, or medications. Tachycardia may increase the oxygen demand and metabolic rate of the brain, which can exacerbate the effects of increased ICP.
