Nursing Elites

1. A nurse is reviewing the medical record of a client who has diabetes insipidus. Which of the following findings should the nurse expect?

• A. Bradycardia
• B. Polyuria
• C. Hypertension
• D. Weight loss

Correct answer: B

Rationale: Polyuria is the correct answer. Diabetes insipidus is characterized by the inability to concentrate urine, leading to excessive urination (polyuria) and thirst. Bradycardia (slow heart rate) is not typically associated with diabetes insipidus. While dehydration from the excessive urination can lead to hypotension rather than hypertension, and weight loss can occur due to fluid loss, the most specific and significant finding expected in diabetes insipidus is polyuria.

2. A nurse is caring for a client who has a prescription for digoxin. Which of the following laboratory values should the nurse monitor to identify an adverse effect of this medication?

• A. Potassium 3.5 mEq/L
• B. Sodium 140 mEq/L
• C. Calcium 9.5 mg/dL
• D. Magnesium 2.0 mEq/L

Correct answer: A

Rationale: The correct answer is A: Potassium 3.5 mEq/L. Digoxin can cause hypokalemia as an adverse effect. Monitoring potassium levels is crucial because low potassium levels can increase the risk of digoxin toxicity. Choices B, C, and D are incorrect as they are not directly associated with potential adverse effects of digoxin. Sodium levels are not typically affected by digoxin, calcium levels are not a primary concern with digoxin therapy, and magnesium levels are not the most important to monitor for digoxin adverse effects.

3. A client is receiving furosemide for heart failure. Which of the following findings should the nurse report to the provider?

• A. Weight loss of 0.5 kg (1.1 lb) in 24 hours.
• B. Heart rate of 68/min.
• C. Potassium level of 3.8 mEq/L.
• D. Urine output of 60 mL/hr.

Correct answer: B

Rationale: The correct answer is B. A heart rate of 68/min is lower than expected and should be reported as it may indicate digoxin toxicity. Choices A, C, and D are within normal limits for a client receiving furosemide for heart failure and do not require immediate reporting. Weight loss may be expected due to diuretic therapy, a potassium level of 3.8 mEq/L is within the normal range, and a urine output of 60 mL/hr indicates adequate renal perfusion.

4. A healthcare professional is reviewing the results of an ABG performed on a client with chronic emphysema. Which of the following results suggests the need for further treatment?

• A. PaO2 level of 89 mm Hg
• B. PaCO2 level of 55 mm Hg
• C. HCO3 level of 25 mEq/L
• D. pH level of 7.37

Correct answer: B

Rationale: The correct answer is B. A high PaCO2 level (55 mm Hg) in a client with chronic emphysema suggests respiratory acidosis, which requires further treatment. In chronic emphysema, impaired gas exchange leads to elevated carbon dioxide levels in the blood. Option A (PaO2 level of 89 mm Hg) is near the normal range and does not indicate immediate treatment. Option C (HCO3 level of 25 mEq/L) and option D (pH level of 7.37) are within normal limits and do not suggest the need for further treatment in this context.

5. A client has a new prescription for nitroglycerin sublingual tablets. Which of the following instructions should the nurse include?

• A. You should lie down before taking this medication.
• B. You should take this medication on an empty stomach.
• C. You should never take a double dose if you miss one.
• D. You should store this medication in its original container at room temperature.

Correct answer: A

Rationale: The correct instruction for a client prescribed nitroglycerin sublingual tablets is to lie down before taking the medication. Nitroglycerin can cause a sudden drop in blood pressure leading to dizziness or fainting, so taking the medication while lying down helps prevent falls. Choice B is incorrect because nitroglycerin is usually taken on an empty stomach to enhance its absorption. Choice C is incorrect as taking a double dose of nitroglycerin can lead to low blood pressure and other adverse effects. Choice D is incorrect as nitroglycerin sublingual tablets should be stored in their original container at room temperature away from light and moisture, not in the refrigerator.
