Nursing Elites

1. The healthcare provider is monitoring a client with diabetic ketoacidosis (DKA). Which of the following laboratory findings would be expected?

• A. Decreased blood glucose levels
• B. Decreased urine ketones
• C. Increased serum bicarbonate
• D. Increased anion gap

Correct answer: D

Rationale: In diabetic ketoacidosis (DKA), there is an excess of ketone bodies produced due to the breakdown of fatty acids for energy, leading to metabolic acidosis. An increased anion gap is a characteristic laboratory finding in DKA. The increased anion gap is a result of the accumulation of ketoacids and lactic acid in the blood, contributing to metabolic acidosis. Therefore, the correct answer is an increased anion gap. Choices A, B, and C are incorrect because in DKA, blood glucose levels are typically elevated, urine ketones are increased due to the breakdown of fatty acids, and serum bicarbonate is usually decreased as it is consumed in an attempt to buffer the acidosis.

2. The nurse is caring for a client with congestive heart failure. On assessment, the nurse notes that the client is dyspneic and that crackles are audible on auscultation. The nurse suspects excess fluid volume. What additional signs would the nurse expect to note in this client if excess fluid volume is present?

• A. Weight loss
• B. Flat neck and hand veins
• C. An increase in blood pressure
• D. A decreased central venous pressure (CVP)

Correct answer: C

Rationale: An increase in blood pressure is a common sign of fluid volume excess in clients with congestive heart failure due to the increased amount of fluid in the vascular system. Weight loss (Choice A) is not typically associated with fluid volume excess. Flat neck and hand veins (Choice B) are signs of fluid volume deficit, not excess. A decreased central venous pressure (CVP) (Choice D) is not expected in a client with fluid volume excess.

3. The client with newly diagnosed diabetes mellitus is being taught about managing blood glucose levels. Which statement indicates a need for further teaching?

• A. I will rotate my insulin injection sites to avoid tissue damage.
• B. I will monitor my blood glucose levels before each meal.
• C. I can eat unlimited fruit as it is healthy.
• D. I should carry a fast-acting carbohydrate with me at all times.

Correct answer: C

Rationale: Choice C indicates a need for further teaching because stating 'I can eat unlimited fruit as it is healthy' is incorrect. While fruits are healthy, they also contain natural sugars that can affect blood glucose levels. Portion control is crucial to managing blood glucose levels effectively. Choices A, B, and D demonstrate correct understanding. Rotating insulin injection sites helps prevent tissue damage, monitoring blood glucose levels before meals aids in managing diabetes effectively, and carrying a fast-acting carbohydrate is essential to treat hypoglycemia promptly.

4. Dr. Kennedy prescribes glipizide (Glucotrol), an oral antidiabetic agent, for a male client with type 2 diabetes mellitus who has been having trouble controlling the blood glucose level through diet and exercise. Which medication instruction should the nurse provide?

• A. Be sure to take glipizide 30 minutes before meals.
• B. Glipizide may cause a low serum sodium level, so make sure you have your sodium level checked monthly.
• C. You won't need to check your blood glucose level after you start taking glipizide.
• D. Take glipizide after a meal to prevent heartburn.

Correct answer: A

Rationale: Glipizide should be taken 30 minutes before meals to maximize its glucose-lowering effect.

5. 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.
