An electrolyte is a mineral or salt dissolved in the body. (Write True or False)
True
False
The Correct Answer is A
Choice A reason: This is correct because an electrolyte is a substance that dissociates into ions when dissolved in water, and can conduct electricity. Some examples of electrolytes in the body are sodium, potassium, calcium, chloride, and bicarbonate.
Choice B reason: This is incorrect because an electrolyte is not a solid or a gas, but a dissolved substance. Electrolytes are essential for maintaining fluid balance, nerve impulses, muscle contractions, and acid-base balance in the body.

Correct Answer is B
Explanation
Choice A reason: This is incorrect because 120 to 140 mEq/L is a low range for serum sodium, which indicates hyponatremia. Hyponatremia can cause confusion, lethargy, seizures, and coma.
Choice B reason: This is correct because 135 to 145 mEq/L is the normal range of serum sodium in adults. Sodium is essential for fluid balance, nerve transmission, and muscle contraction.
Choice C reason: This is incorrect because 150 to 160 mEq/L is a high range for serum sodium, which indicates hypernatremia. Hypernatremia can cause thirst, dry mouth, agitation, and convulsions.
Choice D reason: This is incorrect because 165 to 175 mEq/L is a very high range for serum sodium, which indicates severe hypernatremia. Severe hypernatremia can cause irreversible brain damage and death.
