Nursing Elites

1. 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.

2. A client with hypothyroidism is at risk for which of the following complications?

• A. Thyroid storm
• B. Myxedema coma
• C. Cushing's syndrome
• D. Diabetic ketoacidosis

Correct answer: B

Rationale: Myxedema coma is a severe, life-threatening complication that can occur in individuals with untreated or inadequately treated hypothyroidism. It is characterized by extreme hypothyroidism leading to decreased mental status, hypothermia, bradycardia, and respiratory depression. Thyroid storm (Choice A) is a severe complication of hyperthyroidism, not hypothyroidism. Cushing's syndrome (Choice C) results from prolonged exposure to high levels of cortisol, not related to hypothyroidism. Diabetic ketoacidosis (Choice D) is a complication of uncontrolled diabetes, not directly associated with hypothyroidism.

3. A client is taking NPH insulin daily every morning. The nurse instructs the client that the most likely time for a hypoglycemic reaction to occur is:

• A. 2-4 hours after administration
• B. 6-14 hours after administration
• C. 16-18 hours after administration
• D. 18-24 hours after administration

Correct answer: B

Rationale: The correct answer is B: 6-14 hours after administration. NPH insulin has an onset of action within 1-2 hours, a peak action at 6-14 hours, and a duration of action of 16-24 hours. The peak action period, which is when the risk of hypoglycemia is highest, falls between 6-14 hours after administration. Choices A, C, and D are incorrect because they do not align with the typical action profile of NPH insulin.

4. A client with hypothyroidism is being treated with levothyroxine. Which of the following symptoms would indicate that the client may be receiving too much medication?

• A. Bradycardia
• B. Weight gain
• C. Tachycardia
• D. Cold intolerance

Correct answer: C

Rationale: Tachycardia is a sign of excessive thyroid hormone replacement. Levothyroxine is used to treat hypothyroidism by supplementing thyroid hormone levels. If a client with hypothyroidism experiences symptoms of tachycardia, it suggests that they may be receiving an excessive amount of levothyroxine, causing hyperthyroidism. Bradycardia (Choice A) is more commonly associated with hypothyroidism, not excessive levothyroxine. Weight gain (Choice B) and cold intolerance (Choice D) are also typical symptoms of hypothyroidism and would not typically indicate overmedication.

5. 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

Rationale: The correct instruction when taking metformin (Glucophage) is to take the medication with meals. Taking metformin with meals helps to reduce gastrointestinal side effects and improve absorption. 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.
