Nursing Elites

1. A client with a diagnosis of diabetic ketoacidosis (DKA) is being treated in the ER. Which finding would a nurse expect to note as confirming this diagnosis?

• A. Elevated blood glucose level and a low plasma bicarbonate
• B. Decreased urine output
• C. Increased respirations and an increase in pH
• D. Comatose state

Correct answer: A

Rationale: The correct answer is A: Elevated blood glucose level and a low plasma bicarbonate. Diabetic ketoacidosis (DKA) is characterized by hyperglycemia, ketosis, and metabolic acidosis, reflected by a low plasma bicarbonate. Elevated blood glucose levels are a hallmark of DKA due to the body's inability to use glucose properly. Choices B, C, and D are incorrect. Decreased urine output is not a specific finding associated with DKA. Increased respirations and an increase in pH are not typical in DKA; in fact, respiratory compensation for the metabolic acidosis in DKA leads to Kussmaul breathing (deep, rapid breathing). A comatose state may occur in severe cases of DKA but is not a confirming finding for the diagnosis.

2. What is the mechanism of action of corticotropin (Acthar) when prescribed as replacement therapy for a male client who has undergone surgical removal of a pituitary tumor?

• A. It decreases cyclic adenosine monophosphate (cAMP) production and affects the metabolic rate of target organs.
• B. It interacts with plasma membrane receptors to inhibit enzymatic actions.
• C. It interacts with plasma membrane receptors to produce enzymatic actions that affect protein, fat, and carbohydrate metabolism.
• D. It regulates the threshold for water reabsorption in the kidneys.

Correct answer: C

Rationale: Corticotropin (ACTH) stimulates the adrenal cortex to secrete cortisol and other hormones, affecting protein, fat, and carbohydrate metabolism. Choice A is incorrect because corticotropin does not decrease cAMP production; instead, it stimulates enzymatic actions. Choice B is incorrect because corticotropin does not inhibit enzymatic actions but rather produces enzymatic actions. Choice D is incorrect because corticotropin's mechanism of action does not involve regulating the threshold for water reabsorption in the kidneys.

3. A client with Addison's disease is receiving corticosteroid therapy. The nurse should monitor the client for which of the following potential side effects?

• A. Hypoglycemia
• B. Hypertension
• C. Weight loss
• D. Hyperkalemia

Correct answer: B

Rationale: When a client with Addison's disease is receiving corticosteroid therapy, the nurse should monitor for hypertension as a potential side effect. Corticosteroids can lead to hypertension by causing fluid retention and increased blood volume. Hypoglycemia (Choice A) is not a common side effect of corticosteroid therapy; instead, hyperglycemia is more likely. Weight loss (Choice C) is not a typical side effect of corticosteroid therapy; in fact, weight gain is more common due to fluid retention and increased appetite. Hyperkalemia (Choice D) is a potential side effect of Addison's disease itself due to adrenal insufficiency, but it is not directly caused by corticosteroid therapy.

4. A healthcare professional is monitoring a client newly diagnosed with DM for signs of complications. Which sign or symptom, if exhibited in the client, indicates that the client is at risk for chronic complications of diabetes if blood glucose levels are not adequately managed?

• A. Polyuria
• B. Diaphoresis
• C. Pedal edema
• D. Proteinuria

Correct answer: D

Rationale: Proteinuria is the correct answer because it indicates kidney damage, which is a common complication of uncontrolled diabetes. Elevated blood glucose levels over time can damage the kidneys, leading to proteinuria. Polyuria (excessive urination) is a symptom of diabetes but does not specifically indicate a risk for chronic complications. Diaphoresis (excessive sweating) and pedal edema (swelling of the lower limbs) are not direct indicators of chronic complications related to uncontrolled diabetes.

5. The nurse is caring for a client with hyperaldosteronism. Which of the following laboratory results would the nurse expect?

• A. Hypokalemia
• B. Hypernatremia
• C. Hyperkalemia
• D. Hypocalcemia

Correct answer: A

Rationale: In hyperaldosteronism, there is an excess of aldosterone production, leading to increased sodium retention and potassium excretion by the kidneys. This results in hypokalemia (low potassium levels). Therefore, the correct answer is hypokalemia (Choice A). Hypernatremia (Choice B) is an incorrect choice as hyperaldosteronism primarily affects potassium and not sodium levels. Hyperkalemia (Choice C) is also incorrect because hyperaldosteronism causes potassium excretion, leading to low levels. Hypocalcemia (Choice D) is not typically associated with hyperaldosteronism; instead, it is more related to conditions affecting calcium regulation.
