A nurse is monitoring a client receiving an infusion of IV magnesium sulfate. Which of the following findings would indicate to the nurse that the client is experiencing hypermagnesemia?

Hypertension and headache

Tachycardia and tachypnea

Depressed deep tendon reflexes

Positive Trousseau's sign

Answer and Explanation

The Correct Answer is C

A. Hypertension and headache are not typical signs of hypermagnesemia. These symptoms are more commonly associated with conditions like hypertension or intracranial pressure.
B. Tachycardia and tachypnea are not characteristic of hypermagnesemia. In fact, hypermagnesemia typically causes bradycardia and hypoventilation due to the depressant effect of magnesium on the cardiovascular and respiratory systems.
C. Depressed deep tendon reflexes are a classic sign of hypermagnesemia. Magnesium sulfate acts as a central nervous system depressant, and elevated magnesium levels can impair neuromuscular function, leading to reduced reflexes.
D. Positive Trousseau's sign is indicative of hypocalcemia, not hypermagnesemia. It is a sign of low calcium levels, where a blood pressure cuff inflated above systolic pressure for 3 minutes causes muscle spasms in the hand and forearm.

Correct Answer is ["75"]

Explanation

Total volume: 1800 mL
Infusion time: 24 hours
Calculation: 1800 mL / 24 hours = 75 mL/hour

Therefore, the IV pump should be set to deliver 75 mL/hr.

A. Inverted P wave B. Wide QRS C. Elevated ST segment D. Flattened T wave

Correct Answer is D

Explanation

A. An inverted P wave is not typically associated with hypokalemia but may indicate other conduction abnormalities such as atrial ectopic rhythms.
B. A wide QRS complex is more commonly associated with hyperkalemia rather than hypokalemia. It may also indicate other conduction delays or ventricular issues.
C. An elevated ST segment suggests myocardial injury or pericarditis, not hypokalemia.
D. A flattened T wave is a hallmark of hypokalemia. Low potassium levels affect the repolarization phase of the cardiac cycle, leading to T wave flattening or inversion and, in severe cases, the presence of a U wave.
