Nursing Elites

1. When teaching a male client diagnosed with type 1 diabetes mellitus how diet and exercise affect insulin requirements, Nurse Joy should include which guideline?

• A. You'll need more insulin when you exercise or increase your food intake.
• B. You'll need less insulin when you exercise or reduce your food intake.
• C. You'll need less insulin when you increase your food intake.
• D. You'll need more insulin when you exercise or decrease your food intake.

Correct answer: B

Rationale: When a person with type 1 diabetes exercises, it typically lowers blood glucose levels. As a result, insulin needs are reduced when exercise or food intake is decreased. Choice A is incorrect because more insulin is not typically needed when exercise or food intake is increased. Choice C is incorrect because increasing food intake would generally require more insulin to cover the additional glucose from the food. Choice D is incorrect as decreasing food intake usually leads to a lower need for insulin.

2. Following a unilateral adrenalectomy, Nurse Betty would assess for hyperkalemia indicated by which of the following signs?

• A. Muscle weakness
• B. Tremors
• C. Diaphoresis
• D. Constipation

Correct answer: A

Rationale: Muscle weakness is a classic manifestation of hyperkalemia, an elevated level of potassium in the blood. After an adrenalectomy, where one adrenal gland is removed, there may be a risk of hyperkalemia due to altered hormone regulation. Tremors (Choice B) are not typically associated with hyperkalemia but may be seen in conditions like hypocalcemia. Diaphoresis (Choice C) and constipation (Choice D) are not specific indicators of hyperkalemia. Diaphoresis is excessive sweating and constipation is a common gastrointestinal issue, neither directly related to potassium imbalances.

3. 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.

4. 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.

5. The client with newly diagnosed diabetes mellitus is receiving education from the nurse on managing blood glucose levels. Which statement indicates a need for further teaching?

• A. I will monitor my blood glucose levels regularly.
• B. I can eat whatever I want as long as I take my medication.
• C. I should exercise regularly to help control my blood sugar.
• D. I will rotate my injection sites to avoid tissue damage.

Correct answer: B

Rationale: Choice B indicates a need for further teaching because it suggests that the client can eat whatever they want as long as they take their medication, which is incorrect. Clients with diabetes mellitus need to follow a healthy and balanced diet in addition to taking their medication to effectively manage blood glucose levels. Choices A, C, and D are correct statements for managing diabetes. Monitoring blood glucose levels regularly, engaging in regular exercise to help control blood sugar, and rotating injection sites to avoid tissue damage are all important aspects of diabetes management.
