A healthcare provider caring for a client with severe malnutrition reviews the laboratory results and notes a magnesium level of 1.0 mg/dL. Which electrocardiographic change would the healthcare provider expect to note based on the magnesium level?
- A. Prominent U waves
- B. Prolonged PR interval
- C. Depressed ST segment
- D. Widened QRS complexes
Correct Answer: C
Rationale: A magnesium level of 1.0 mg/dL can cause a depressed ST segment on the ECG. Magnesium deficiency commonly leads to ST segment depression on an electrocardiogram. Prominent U waves are associated with hypokalemia, prolonged PR interval is seen in conditions like first-degree heart block, and widened QRS complexes are typically related to conditions affecting the conduction system of the heart, such as bundle branch blocks.

- A. Bananas

A client with type 2 DM is prescribed metformin (Glucophage). The nurse should include which instruction when teaching the client about this medication?
- A. Take the medication with meals.
- B. Take the medication on an empty stomach.
- C. Avoid taking the medication if you miss a meal.
- D. Take the medication before bedtime.
Correct Answer: A

Choice B is incorrect because taking metformin on an empty stomach can increase the risk of gastrointestinal side effects. Choice C is incorrect because missing a meal does not mean the medication should be avoided; the client should still take it with the next meal. Choice D is incorrect because there is no specific recommendation to take metformin before bedtime.
