Nursing Elites

1. A nurse is caring for a client in preterm labor who is receiving magnesium sulfate. Which of the following is an indication of magnesium toxicity?

• A. Blood glucose of 160 mg/dL
• B. Urine output of 20 mL/hour
• C. Systolic BP of 140 mm Hg
• D. Respiratory rate of 20/min

Correct answer: B

Rationale: The correct answer is B: Urine output of 20 mL/hour. Urine output below 30 mL/hour is a sign of magnesium toxicity due to the risk of accumulation in the body. Choices A, C, and D are not indicative of magnesium toxicity. Elevated blood glucose, systolic blood pressure, and normal respiratory rate are not specific signs of magnesium toxicity.

2. A nurse is caring for a client receiving corticosteroids. Which of the following should the nurse monitor?

• A. Blood glucose levels
• B. Blood pressure
• C. Serum potassium levels
• D. Both A and B

Correct answer: D

Rationale: When a client is receiving corticosteroids, the nurse should monitor both blood glucose levels and blood pressure. Corticosteroids can elevate blood glucose levels, leading to hyperglycemia, and may cause hypertension. Monitoring these parameters is essential to detect and address any potential adverse effects promptly. While monitoring serum potassium levels is important in some situations, it is not a primary concern when caring for a client receiving corticosteroids. Therefore, choices A and B are the most appropriate options for monitoring in this scenario, making option D the correct answer.

3. A nurse is assessing a client for signs of heart failure. Which of the following findings should the nurse monitor?

• A. Decreased heart rate
• B. Peripheral edema
• C. Increased energy levels
• D. Hyperglycemia

Correct answer: B

Rationale: The correct answer is B: Peripheral edema. Peripheral edema, the accumulation of fluid causing swelling in the extremities, is a classic sign of heart failure due to fluid overload. This occurs because the heart's reduced pumping efficiency leads to fluid backup in the circulatory system. Choices A, C, and D are incorrect. Decreased heart rate is not typically associated with heart failure; instead, tachycardia or an increased heart rate may be observed. Increased energy levels are not an expected finding in heart failure, as this condition often causes fatigue and weakness. Hyperglycemia is not a direct sign of heart failure; however, it can be present in individuals with uncontrolled diabetes or as a result of certain treatments, but it is not a specific indicator of heart failure.

4. A nurse is caring for a client who is hyperventilating and has the following ABG results: pH 7.50, PaCO2 29 mm Hg, and HCO3- 25 mEq/L. The nurse should recognize that the client has which of the following acid-base imbalances?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. In this scenario, the client is hyperventilating, leading to excessive elimination of carbon dioxide. As a result, the PaCO2 decreases, causing a decrease in hydrogen ion concentration and an increase in pH, resulting in respiratory alkalosis. Choice A, Respiratory acidosis, is incorrect because the ABG results show a low PaCO2, not an elevated one. Choices C and D, Metabolic acidosis and Metabolic alkalosis, do not align with the ABG results provided, which point towards a respiratory, not metabolic, imbalance.

5. A nurse is preparing to administer a dose of insulin. Which of the following should the nurse do first?

• A. Check the expiration date
• B. Verify the client's blood glucose level
• C. Obtain the client's weight
• D. Assess for signs of hypoglycemia

Correct answer: B

Rationale: The correct answer is to verify the client's blood glucose level first before administering insulin. This step is crucial to determine the appropriate dose of insulin based on the client's current blood glucose level. Checking the expiration date (Choice A) is important but not the first step in this scenario. Obtaining the client's weight (Choice C) is not directly related to the immediate administration of insulin. Assessing for signs of hypoglycemia (Choice D) should be done after administering insulin to monitor for potential side effects or adverse reactions.
