Which assessment finding is most indicative of hypernatremia?

Ascending muscle weakness

Muscle tetany and hyperreflexia

Poor turgor and dry mucous membranes

Bradycardia and hypotension

Answer and Explanation

The Correct Answer is C

A. Ascending muscle weakness is more characteristic of hypokalemia (low potassium levels) rather than hypernatremia.
B. Muscle tetany and hyperreflexia are typically seen in hypocalcemia (low calcium levels) or hypomagnesemia (low magnesium levels), not hypernatremia.
C. Hypernatremia (high sodium levels) commonly causes dehydration, which results in poor skin turgor and dry mucous membranes. This is a key clinical sign of hypernatremia.
D. Bradycardia and hypotension are more commonly associated with hypovolemia (low blood volume) or hypotension, but they are not specific to hypernatremia.

Correct Answer is B

Explanation

A. Flushed skin is typically associated with fever or infection, not with hyponatremia (low sodium levels).
B. Confusion is a common symptom of hyponatremia, especially when sodium levels drop significantly. The low sodium level affects brain function, leading to confusion, altered mental status, and even seizures in severe cases.
C. Extreme thirst is more commonly seen in hypernatremia (high sodium levels) as the body attempts to correct the imbalance by stimulating thirst.
D. Fever is not a direct consequence of hyponatremia but could be associated with an underlying infection or other conditions.

Correct Answer is ["125"]

Explanation

Determine the infusion time: The total dose is 40 mEq, and it's being infused at a rate of 10 mEq/hr.
Therefore, the total infusion time is 40 mEq / 10 mEq/hr = 4 hours.
Calculate the infusion rate in mL/hr: The total volume is 500 mL, and the infusion time is 4 hours.
So, the infusion rate is 500 mL / 4 hours = 125 mL/hr.
