. A 65-year-old patient presents to the emergency department with sudden numbness and weakness in the face, arm, and leg on one side of the body difficulty speaking, and severe headache with no known cause. Which of the following is the most likely diagnosis?
Stroke
Migraine
Hypoglycemia
Transient ischemic Attack (TIA)
The Correct Answer is A
A. Stroke: The sudden onset of one-sided weakness, numbness, difficulty speaking, and severe headache are classic symptoms of an acute stroke, where blood flow to part of the brain is interrupted, leading to neurological deficits.
B. Migraine: While migraines can cause headache and some neurological symptoms, they usually include visual disturbances, nausea, or photophobia rather than one-sided weakness and numbness.
C. Hypoglycemia: Hypoglycemia can cause confusion, weakness, and headache, but it typically lacks the focal neurological symptoms, like one-sided weakness and numbness.
D. Transient Ischemic Attack (TIA): A TIA can cause similar symptoms, but the deficits are usually transient and resolve within 24 hours without lasting neurological damage. Persistent symptoms are more indicative of a stroke.

Correct Answer is C
Explanation
A. Encourage the client to walk on the injured ankle to promote circulation. Weight-bearing activities should be avoided initially after a Grade II sprain to prevent further injury.
B. Immerse the ankle in warm water immediately after the injury. Ice, rather than warmth, is recommended immediately following an injury to reduce swelling and inflammation.
C. Apply ice to the affected ankle for the first 24-72 hours. Applying ice for 24-72 hours helps reduce swelling and pain by causing vasoconstriction and controlling inflammation in the acute phase.
D. Perform deep tissue massage on the injured area to reduce pain. Massaging a newly sprained ankle can aggravate inflammation and cause additional tissue damage.
Correct Answer is A
Explanation
A. Serum sodium levels: Desmopressin can lead to water retention and potentially hyponatremia. Monitoring serum sodium is crucial to prevent electrolyte imbalance.
B. Serum magnesium levels: Magnesium is not typically impacted by desmopressin treatment in central diabetes insipidus.
C. Serum potassium levels: Desmopressin does not generally affect potassium levels in patients with diabetes insipidus.
D. Serum calcium levels: Calcium levels are not directly influenced by desmopressin or diabetes insipidus.
