Nursing Elites

1. A nurse is caring for a client who has chronic kidney disease and a serum potassium level of 6.5 mEq/L. Which of the following actions should the nurse take?

• A. Administer sodium bicarbonate
• B. Administer sodium polystyrene sulfonate
• C. Administer calcium gluconate
• D. Administer calcium carbonate

Correct answer: B

Rationale: The correct action for the nurse to take is to administer sodium polystyrene sulfonate. This medication promotes potassium excretion and helps lower serum potassium levels in clients with hyperkalemia, which is indicated by a high potassium level. Sodium bicarbonate (choice A) is not used to treat hyperkalemia. Calcium gluconate (choice C) and calcium carbonate (choice D) are used to manage hyperkalemia by stabilizing cell membranes but are not the initial treatment choice for lowering potassium levels.

2. A nurse is caring for a client who has a chest tube. Which of the following actions should the nurse take?

• A. Clamp the chest tube for 15 minutes every 2 hours.
• B. Empty the drainage collection chamber when it is half full.
• C. Keep the drainage system below the level of the client's chest.
• D. Strip the chest tube every 2 hours to maintain patency.

Correct answer: C

Rationale: The correct action the nurse should take when caring for a client with a chest tube is to keep the drainage system below the level of the client's chest. This positioning helps prevent fluid from flowing back into the pleural space, ensuring proper drainage and effective functioning of the chest tube. Clamping the chest tube intermittently or stripping it frequently can lead to complications and should be avoided. Emptying the drainage collection chamber at specific intervals may vary based on institutional protocols, but it should be done when it is no more than two-thirds full to prevent backflow and maintain accurate monitoring of drainage output.

3. A patient is receiving radiation therapy. Which of the following skin care instructions should the nurse provide?

• A. Apply a heating pad to the radiation site.
• B. Use scented lotions to moisturize the skin.
• C. Keep the radiation site covered with a bandage.
• D. Wear loose clothing over the radiation site.

Correct answer: D

Rationale: Correct Answer: The nurse should instruct the patient to wear loose clothing over the radiation site. This helps prevent skin irritation and promotes healing by reducing friction and irritation on the treated area.\nChoice A is incorrect because applying a heating pad can further irritate the skin that is already sensitive due to radiation therapy.\nChoice B is incorrect because scented lotions may contain ingredients that could further irritate the skin.\nChoice C is incorrect because covering the radiation site with a bandage can trap moisture and lead to skin breakdown, increasing the risk of infection.

4. How should bleeding in a patient on warfarin be monitored?

• A. Monitor INR levels
• B. Monitor hemoglobin levels
• C. Monitor potassium levels
• D. Monitor platelet count

Correct answer: A

Rationale: The correct answer is to monitor INR levels. INR levels are the most critical indicator for monitoring bleeding risk in patients on warfarin. INR stands for International Normalized Ratio and specifically measures the clotting tendency of the blood. Monitoring hemoglobin levels, potassium levels, or platelet count are not as directly relevant to assessing bleeding risk in patients on warfarin.

5. A healthcare provider is reviewing laboratory results for a client who has diabetes mellitus. Which of the following tests is an indicator of long-term blood glucose control?

• A. Fasting blood glucose
• B. Glycosylated hemoglobin (HbA1c)
• C. Random blood glucose
• D. Postprandial blood glucose

Correct answer: B

Rationale: The correct answer is B, Glycosylated hemoglobin (HbA1c). HbA1c provides a measure of long-term blood glucose control over the past 2-3 months. This test reflects the average blood glucose levels during this period, making it a valuable tool in managing diabetes. Choices A, C, and D are not indicators of long-term blood glucose control. Fasting blood glucose measures the current glucose level after a period of not eating, random blood glucose provides a snapshot of the current glucose level, and postprandial blood glucose measures the glucose level after a meal.
