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.
The urine volume would enhance if ADH was not added to the collecting duct. This is because the ADH works on the collecting ducts where the increase permeability for water is improved, so less water is perspired into the urine, so urine evolves more concentrated.
<h3>What happens to urine volume when ADH advances?</h3>
- ADH improves the permeability to water of the distal serpentine tubule and collecting duct, which is normally impervious to water. This effect causes heightened water reabsorption and retention and reduces the volume of urine produced comparable to its ion content.
- In SIADH, the body is unable to subdue the secretion of ADH, conducting to insufficient water excretion and reduced urine output. Normally, when water is ingested, serum tonicity and osmolality reduction, and ADH are quelled, resulting in an output of dilute (less concentrated) urine.
- A hormone that allows blood vessels narrow and helps the kidneys control the portion of water and salt in the body. This enables the control of blood pressure and the quantity of urine that is made. Antidiuretic hormone is made by a portion of the brain called the hypothalamus and is perspired into the blood by the pituitary gland.

An AED is in use and has indicated that a shock is needed, the second rescuer should start compressions immediately after delivering the shock to the individual.
<h3>What is CPR?</h3>
This is referred to as Cardiopulmonary resuscitation and is an emergency lifesaving technique performed when the heart stops beating.This include series of compressions and artificial ventilation so as to ensure the brain functions are preserved.
In the case where an automated external defibrillator (AED) is used and indicates a shock is needed, it is best to give it immediately.
This should then be followed by compressions from the second rescuer which is therefore the reason why it was chosen as the correct choice.
