Nursing Elites

1. A nurse is reviewing the laboratory results of a client who has Cushing's disease. The nurse should expect an increase in which of the following laboratory values?

• A. Serum glucose level
• B. Serum potassium level
• C. Serum calcium level
• D. Serum sodium level

Correct answer: A

Rationale: The correct answer is A: Serum glucose level. In Cushing's disease, there is increased cortisol production, leading to elevated blood glucose levels. This occurs due to the role of cortisol in promoting gluconeogenesis and insulin resistance. Choices B, C, and D are incorrect because Cushing's disease is not typically associated with alterations in serum potassium, calcium, or sodium levels.

2. A nurse is providing teaching to a client who has a new diagnosis of hypertension. Which of the following dietary recommendations should the nurse include?

• A. Limit sodium intake to 4 grams per day.
• B. Limit protein intake to 80 grams per day.
• C. Limit saturated fat intake to 7% of daily calories.
• D. Limit fluid intake to 1,500 mL per day.

Correct answer: C

Rationale: The correct answer is to limit saturated fat intake to 7% of daily calories. This recommendation is crucial for clients with hypertension to lower cholesterol levels and promote heart health. Choice A, limiting sodium intake to 4 grams per day, is important for hypertension but not the best recommendation compared to limiting saturated fats. Choice B, limiting protein intake to 80 grams per day, is not a primary dietary concern for hypertension. Choice D, limiting fluid intake to 1,500 mL per day, is not a standard recommendation for hypertension management.

3. A nurse is caring for a client who is receiving total parenteral nutrition (TPN). Which of the following laboratory values indicates the TPN is effective?

• A. Albumin 3.5 g/dL
• B. Hemoglobin 8 g/dL
• C. WBC count 15,000/mm3
• D. Blood glucose 110 mg/dL

Correct answer: D

Rationale: The correct answer is D. A blood glucose level of 110 mg/dL indicates that the TPN is effective in maintaining normal glucose levels. Hemoglobin level (choice B) is related to anemia and not directly indicative of TPN effectiveness. Albumin level (choice A) is a marker of nutritional status over a longer term and may not reflect immediate TPN effectiveness. White blood cell count (choice C) is related to infection or inflammation and is not a direct indicator of TPN effectiveness.

4. 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.

5. A nurse is caring for a client who has a pulmonary embolism. Which of the following findings indicates the effectiveness of the treatment?

• A. A chest x-ray reveals increased density in all lung fields.
• B. The client reports feeling less anxious.
• C. Diminished breath sounds are auscultated bilaterally.
• D. ABG results include pH 7.48, PaO2 77 mm Hg, and PaCO2 47 mm Hg.

Correct answer: B

Rationale: The correct answer is B. In a client with a pulmonary embolism, improvement in anxiety levels can indicate the effectiveness of treatment as it suggests better oxygenation and perfusion. Choices A, C, and D do not directly reflect the effectiveness of treatment for a pulmonary embolism. Increased density in all lung fields on a chest x-ray may indicate worsening of the condition, diminished breath sounds suggest impaired lung function, and ABG results with a pH of 7.48, PaO2 of 77 mm Hg, and PaCO2 of 47 mm Hg do not specifically indicate treatment effectiveness for a pulmonary embolism.
