1. Which of the following laboratory values should the nurse monitor in a client with Cushing's syndrome?

• A. Blood glucose levels
• B. Serum calcium levels
• C. Serum potassium levels
• D. Serum sodium levels

Correct answer: A

Rationale: The correct answer is A: Blood glucose levels. In Cushing's syndrome, there is excess cortisol in the body which leads to increased blood glucose levels due to its effect on glucose metabolism. Elevated blood glucose levels are a common finding in individuals with Cushing's syndrome. Monitoring blood glucose levels is crucial as it helps in assessing and managing hyperglycemia in these patients. Choice B, serum calcium levels, is not typically a priority in monitoring for Cushing's syndrome. While abnormalities in calcium levels can occur in some endocrine disorders, hypercalcemia is not a hallmark of Cushing's syndrome. Choice C, serum potassium levels, and Choice D, serum sodium levels, are not directly associated with Cushing's syndrome. While electrolyte imbalances can occur in various conditions, they are not specifically linked to Cushing's syndrome as blood glucose levels are.

2. Which of the following is true about effective leadership?

• A. Leadership traits can be learned through experience and reflection.
• B. Nurses can learn to become good leaders by acting as good leaders and reflecting on leadership qualities they have and those they can improve upon.
• C. Focus on leadership activities required for the day is essential for effective leadership.
• D. Taking advantage of every opportunity to be a leader is crucial, creating those opportunities as often as possible, especially after gaining experience as a nurse.

Correct answer: B

Rationale: Choice B is correct because nurses can develop effective leadership skills by actively engaging as good leaders and reflecting on their existing leadership qualities and areas for improvement. This process of self-assessment and continuous improvement is crucial in becoming a successful leader. Choice A is incorrect as leadership traits can be learned through experience and reflection rather than being impossible to acquire from a book. Choice C is incorrect as effective leadership involves focusing on long-term goals and strategies, not just daily activities. Choice D is incorrect because while seizing leadership opportunities is important, it should be done strategically and with a solid foundation of experience in nursing to ensure successful leadership outcomes.

3. An agitated, confused female client arrives in the emergency department. Her history includes type 1 diabetes mellitus, hypertension, and angina pectoris. Assessment reveals pallor, diaphoresis, headache, and intense hunger. A stat blood glucose sample measures 42 mg/dl, and the client is treated for an acute hypoglycemic reaction. After recovery, the nurse teaches the client to treat hypoglycemia by ingesting:

• A. 2 to 5 g of a simple carbohydrate.
• B. 10 to 15 g of a simple carbohydrate.
• C. 18 to 20 g of a simple carbohydrate.
• D. 25 to 30 g of a simple carbohydrate.

Correct answer: B

Rationale: The correct answer is B: 10 to 15 g of a simple carbohydrate. In the treatment of hypoglycemia, it is important to administer a specific amount of simple carbohydrates to raise blood glucose levels effectively without causing hyperglycemia. 10 to 15 g of simple carbohydrates, such as glucose tablets, fruit juice, or regular soft drinks, is recommended to rapidly increase blood sugar levels in clients experiencing hypoglycemia. Choices A, C, and D are incorrect as they either provide too little or too much glucose, which may not effectively treat the hypoglycemic episode or may lead to rebound hyperglycemia.

4. A client with hyperaldosteronism is at risk for which of the following electrolyte imbalances?

• A. Hyperkalemia
• B. Hyponatremia
• C. Hypokalemia
• D. Hypercalcemia

Correct answer: C

Rationale: In hyperaldosteronism, there is an excessive secretion of aldosterone, a hormone that promotes potassium excretion in the kidneys. This leads to low potassium levels in the blood, known as hypokalemia. Therefore, the correct answer is hypokalemia (Choice C). Hyperkalemia (Choice A) is the opposite condition, where there is high potassium levels in the blood and is not typically associated with hyperaldosteronism. Hyponatremia (Choice B) is a low sodium level, which is not directly related to aldosterone function. Hypercalcemia (Choice D) is an elevated calcium level and is not typically a direct result of hyperaldosteronism.

5. 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.
