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. During a class on exercise for diabetic clients, a female client asks the nurse educator how often to exercise. The nurse educator advises the clients to exercise how often to meet the goals of planned exercise?

• A. At least once a week
• B. At least three times a week
• C. At least five times a week
• D. Every day

Correct answer: C

Rationale: Exercising at least five times a week is recommended to meet the goals of planned exercise for diabetic clients. This frequency helps in managing blood sugar levels effectively and improving overall health. Exercising once a week (Choice A) may not provide sufficient benefits or consistency required for diabetic clients. Exercising three times a week (Choice B) is better but may still fall short of the recommended frequency for optimal outcomes. Exercising every day (Choice D) may lead to burnout or overtraining if not properly balanced with rest days, which could be counterproductive for diabetic clients.

3. A client with hyperthyroidism is prescribed propranolol. The nurse understands that this medication is used to:

• A. Increase metabolism
• B. Reduce anxiety
• C. Decrease heart rate
• D. Increase blood pressure

Correct answer: C

Rationale: Propranolol is a beta-blocker commonly used in the management of hyperthyroidism. It works by blocking the effects of adrenaline, resulting in a decrease in heart rate and blood pressure. Choice A is incorrect because propranolol does not increase metabolism; instead, it may have a mild inhibitory effect. Choice B is incorrect as propranolol is not primarily used to reduce anxiety, although it may have some anxiolytic effects. Choice D is incorrect as propranolol actually decreases blood pressure by blocking the effects of adrenaline on the heart and blood vessels.

4. The client with type 2 DM is receiving dietary instructions from the nurse regarding the prescribed diabetic diet. The nurse determines that the client understands the instructions if the client states that:

• A. I need to skip meals if my blood glucose level is elevated.
• B. I need to eat a small meal or snack every 2 to 3 hours.
• C. I need to avoid using concentrated sweets in my diet.
• D. I need to eat a high-protein, low-carbohydrate diet.

Correct answer: C

Rationale: The correct answer is C: 'I need to avoid using concentrated sweets in my diet.' Clients with type 2 diabetes should avoid concentrated sweets as they can cause rapid spikes in blood glucose levels, which can be detrimental to their health. Option A is incorrect because skipping meals can lead to fluctuations in blood glucose levels. Option B is incorrect as it does not address the specific issue of avoiding concentrated sweets. Option D is incorrect because a high-protein, low-carbohydrate diet is not typically recommended as the primary approach for managing type 2 diabetes.

5. 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.
