Which of the following best describes Chvostek's sign assessment?
Assessing a client's blood pressure using a sphygmomanometer.
Assessing a client's muscle contractions by tapping on the facial nerve.
Assessing a client's heart rate using a stethoscope.
Assessing a client's respiratory rate using a pulse oximeter.
The Correct Answer is B
A. Assessing blood pressure with a sphygmomanometer is unrelated to Chvostek's sign, which specifically evaluates neuromuscular excitability.
B. Chvostek's sign is assessed by tapping the facial nerve near the cheekbone. A positive response, such as twitching of the facial muscles, indicates hypocalcemia or neuromuscular irritability.
C. Assessing heart rate with a stethoscope does not involve evaluating neuromuscular function or calcium levels.
D. Monitoring respiratory rate with a pulse oximeter is unrelated to Chvostek's sign and does not assess neuromuscular excitability.

Correct Answer is ["125"]
Explanation
· Total volume: 250 mL
· Infusion time: 2 hours
· Calculation: 250 mL / 2 hours = 125 mL/hour
Correct Answer is C
Explanation
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.
