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. The client with hyperthyroidism is receiving propylthiouracil (PTU). The nurse should monitor for which of the following potential side effects?

• A. Leukopenia
• B. Hyperglycemia
• C. Hypertension
• D. Weight gain

Correct answer: A

Rationale: The correct answer is A: Leukopenia. Propylthiouracil can lead to bone marrow suppression, resulting in leukopenia. Monitoring white blood cell counts is crucial to detect this potential side effect early. Choice B, hyperglycemia, is not typically associated with propylthiouracil use. Choice C, hypertension, is not a common side effect of propylthiouracil. Choice D, weight gain, is also not a typical side effect of propylthiouracil therapy.

3. A client with Graves' disease is prescribed propranolol. The nurse understands that the purpose of this medication is to:

• A. Treat the underlying cause of the disease
• B. Reduce thyroid hormone production
• C. Alleviate symptoms such as tachycardia and tremors
• D. Increase energy levels

Correct answer: C

Rationale: The correct answer is C: Alleviate symptoms such as tachycardia and tremors. Propranolol is a beta-blocker that helps manage symptoms like tachycardia (fast heart rate) and tremors in patients with Graves' disease. Choice A is incorrect because propranolol does not address the underlying cause of Graves' disease, which is autoimmune in nature. Choice B is incorrect because propranolol does not directly reduce thyroid hormone production; it mainly targets the symptoms. Choice D is incorrect because while propranolol may help with symptoms like tachycardia, it is not intended to increase energy levels.

4. A client with diabetes mellitus is scheduled for surgery. The nurse should prioritize which of the following preoperative actions?

• A. Administer a full dose of insulin before surgery
• B. Hold all oral hypoglycemic agents the day before surgery
• C. Monitor blood glucose levels closely before surgery
• D. Instruct the client to avoid all fluids the morning of surgery

Correct answer: C

Rationale: Monitoring blood glucose levels closely before surgery is the priority for a client with diabetes mellitus. This allows for early detection of any abnormalities and helps prevent hypo- or hyperglycemia complications that can arise during the perioperative period. Option A is incorrect because insulin dosing should be individualized based on the client's current blood glucose levels and the surgical plan. Option B is incorrect as abruptly holding oral hypoglycemic agents can lead to uncontrolled blood glucose levels. Option D is incorrect as adequate fluid intake is important for the client's hydration status and overall well-being before surgery.

5. The healthcare provider is assessing a client with hypothyroidism. Which of the following symptoms would the provider expect to find?

• A. Weight loss
• B. Heat intolerance
• C. Bradycardia
• D. Diarrhea

Correct answer: C

Rationale: Bradycardia is a common symptom of hypothyroidism because the condition leads to a decreased metabolic rate. Weight loss (Choice A) is more commonly associated with hyperthyroidism, where the metabolic rate is increased. Heat intolerance (Choice B) is also more indicative of hyperthyroidism due to increased sensitivity to heat. Diarrhea (Choice D) is not a typical symptom of hypothyroidism; rather, constipation is more common due to the slow-down of the digestive system.
