Nursing Elites

1. A client with diabetes mellitus is receiving an oral antidiabetic medication. The nurse should monitor for which of the following adverse effects?

• A. Weight gain
• B. Hypoglycemia
• C. Hyperglycemia
• D. Bradycardia

Correct answer: B

Rationale: The correct answer is B: Hypoglycemia. When a client with diabetes mellitus is taking oral antidiabetic medication, the nurse should closely monitor for hypoglycemia, which is a common adverse effect. Hypoglycemia occurs when the blood sugar levels drop below normal range, leading to symptoms like confusion, shakiness, and sweating. Weight gain (Choice A) is not a typical adverse effect of oral antidiabetic medications. Hyperglycemia (Choice C) is the opposite of the desired effect of antidiabetic medications, which aim to lower blood sugar levels. Bradycardia (Choice D) is not directly associated with oral antidiabetic medications; it refers to a slow heart rate.

2. A male client is admitted for treatment of the syndrome of inappropriate antidiuretic hormone (SIADH). Which nursing intervention is appropriate?

• A. Infusing I.V. fluids rapidly as ordered
• B. Encouraging increased oral intake
• C. Restricting fluids
• D. Administering glucose-containing I.V. fluids as ordered

Correct answer: C

Rationale: The correct nursing intervention for a male client with SIADH is to restrict fluids. In SIADH, there is excess release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. Restricting fluids helps prevent further dilutional hyponatremia by reducing water intake. Infusing I.V. fluids rapidly (choice A) would worsen the condition by adding more fluids, encouraging increased oral intake (choice B) is contraindicated as it adds more fluids, and administering glucose-containing I.V. fluids (choice D) is not a standard treatment for SIADH.

3. 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.

4. Early this morning, a female client had a subtotal thyroidectomy. During evening rounds, Nurse Tina assesses the client, who now has nausea, a temperature of 105°F (40.5°C), tachycardia, and extreme restlessness. What is the most likely cause of these signs?

• A. Diabetic ketoacidosis
• B. Thyroid crisis
• C. Hypoglycemia
• D. Tetany

Correct answer: B

Rationale: The correct answer is B: Thyroid crisis. Thyroid crisis, also known as thyroid storm, is a life-threatening condition that can occur after a thyroidectomy. Symptoms include high fever, tachycardia, extreme restlessness, and other signs of severe hyperthyroidism. Diabetic ketoacidosis (choice A) is a complication of diabetes characterized by hyperglycemia, ketosis, and acidosis, not typically seen post-thyroidectomy. Hypoglycemia (choice C) is low blood sugar levels and would not present with the symptoms described. Tetany (choice D) is a condition of involuntary muscle spasms due to low calcium levels and is not directly related to the symptoms observed in this scenario.

5. A client with hyperthyroidism is prescribed methimazole. The nurse should instruct the client that the purpose of this medication is to:

• A. Decrease thyroid hormone production
• B. Increase thyroid hormone production
• C. Suppress the immune system
• D. Prevent thyroid storm

Correct answer: A

Rationale: The correct answer is A: Decrease thyroid hormone production. Methimazole works by inhibiting the synthesis of thyroid hormones, specifically by blocking the enzyme responsible for this process. By reducing the production of thyroid hormones, methimazole helps to normalize the elevated levels seen in hyperthyroidism. Choices B, C, and D are incorrect. Choice B, 'Increase thyroid hormone production,' is inaccurate as methimazole actually decreases thyroid hormone production. Choice C, 'Suppress the immune system,' is unrelated to the mechanism of action of methimazole. Choice D, 'Prevent thyroid storm,' is not the primary purpose of methimazole; while it may help prevent worsening of hyperthyroidism, its main action is to reduce thyroid hormone levels.
