Answer:
exposure A quantity used to express external ionizing radiation, or to indicate presence of radionuclides or radiation affecting individuals or populations (for example, “exposure” to radionuclides in the environment). gray (Gy) The SI unit of absorbed dose. 1 Gy equals an absorbed dose of 1 J/kg (100 rad).
Explanation:
Answer: The next most appropriate step would be a LUMBAR PUNCTURE.
Explanation:
A LUMBAR PUNCTURE is a medical procedure that is usually carried out by a trained health personnel. It is a procedure that is carried out in the lumbar region of the spinal cord to access and obtain the cerebrospinal fluid which is used for further diagnosis of an underlying disease or illness.
A LUMBAR PUNCTURE is often adviced when the symptoms of a disease is related to the central nervous system. From the symptoms observed from the 19-year-old woman at the emergency department which includes:
--> generalized headache which is increasing in intensity,
--> blurred vision,
--> intermittent diplopia,
--> vague dizziness.
--> bilateral papilledema and
--> normal MRI of the brain.
Since the MRI of the brain is normal, the most appropriate step to be taken by the health care provider is a lumbar puncture which enables a direct access to the cerebrospinal fluid. This would help to rule out an elevated intracranial pressure which may be the cause of the generalized headache which is increasing in intensity.
Studies show that a 1% increase in dietary saturated fatty acids will raise the risk of heart disease by 2%.
Saturated fatty acid :
A saturated fatty acid is a type of fatty acid that lacks unsaturated linkages between carbon atoms. This type of fatty acid is saturated because it no longer has any double bonds, which prevents it from absorbing any more hydrogen. Animal fats frequently contain saturated fatty acids.
In the worldwide, cardiovascular disease (CVD) is the leading cause of death and disability. Additionally, a poor diet is a major CVD risk factor. Therefore, changes in diet may help to considerably lower the occurrence of CVD. It is well known that saturated fatty acids (SFA) raise LDL cholesterol, a major risk factor for cardiovascular disease.
