1. Which electrolyte imbalance is most concerning in a patient taking digoxin?

• A. Monitor potassium levels
• B. Monitor calcium levels
• C. Monitor sodium levels
• D. Monitor magnesium levels

Correct answer: A

Rationale: The correct answer is to monitor potassium levels. Patients taking digoxin are at risk of developing toxicity due to hypokalemia. Low potassium levels can potentiate the toxic effects of digoxin on the heart, leading to serious arrhythmias. Monitoring calcium levels (Choice B) is not the primary concern in patients taking digoxin. While calcium levels play a role in cardiac function, hypocalcemia is not directly associated with digoxin toxicity. Monitoring sodium levels (Choice C) is important for other conditions but is not the primary concern in a patient taking digoxin. Monitoring magnesium levels (Choice D) is also essential, but hypomagnesemia is not as directly linked to digoxin toxicity as hypokalemia.

2. A client has a central venous catheter. Which of the following actions should be taken to prevent an air embolism?

• A. Keep the catheter clamped when not in use
• B. Have the client perform the Valsalva maneuver while the catheter is removed
• C. Use a non-coring needle to access the catheter
• D. Flush the catheter with 0.9% sodium chloride every 24 hours

Correct answer: B

Rationale: The correct action to prevent an air embolism in a client with a central venous catheter is to have the client perform the Valsalva maneuver while the catheter is removed. This maneuver helps to close the airway and prevent air from entering the bloodstream. Keeping the catheter clamped at all times (Choice A) is not necessary and may lead to clot formation. Using a non-coring needle (Choice C) is important for accessing the catheter but does not specifically prevent air embolism. Flushing the catheter with 0.9% sodium chloride (Choice D) helps maintain patency but does not directly prevent air embolism.

3. A client with diabetes mellitus is being taught by a nurse on managing hypoglycemia. Which of the following instructions should the nurse include?

• A. Avoid consuming carbohydrate-rich foods.
• B. Consume 15 grams of a fast-acting carbohydrate.
• C. Drink a glass of water to raise blood glucose levels.
• D. Eat a snack before exercising to prevent hypoglycemia.

Correct answer: B

Rationale: The correct answer is B: Consume 15 grams of a fast-acting carbohydrate. Consuming 15 grams of a fast-acting carbohydrate, such as glucose tablets or juice, helps raise blood glucose levels quickly in cases of hypoglycemia. Choice A is incorrect because avoiding carbohydrate-rich foods during hypoglycemia can worsen the condition. Choice C is incorrect as drinking water does not effectively raise blood glucose levels. Choice D is incorrect as eating a snack before exercising is more related to preventing exercise-induced hypoglycemia, not managing hypoglycemia.

4. A nurse is caring for a client who is 3 days postoperative following a bowel resection. Which of the following findings should the nurse report to the provider?

• A. Heart rate of 80/min
• B. White blood cell count of 9,000/mm3
• C. Temperature of 37.8°C (100°F)
• D. Blood pressure of 118/78 mm Hg

Correct answer: C

Rationale: A temperature of 37.8°C (100°F) should be reported to the provider as it can indicate infection, a common postoperative complication. A normal heart rate of 80/min (Choice A), white blood cell count of 9,000/mm3 (Choice B), and blood pressure of 118/78 mm Hg (Choice D) are within normal ranges and do not necessarily indicate a complication postoperatively.

5. What is the best way to assess a patient's respiratory function after surgery?

• A. Check oxygen saturation
• B. Auscultate lung sounds
• C. Check for abnormal breath sounds
• D. Check skin color

Correct answer: A

Rationale: The correct answer is to check oxygen saturation. This is because checking oxygen saturation provides a direct measure of how well the patient is oxygenating post-surgery. It helps healthcare providers assess if the patient is receiving enough oxygen to meet their body's needs. Auscultating lung sounds (choice B) is important to assess respiratory function but may not provide an immediate indication of oxygenation status. Checking for abnormal breath sounds (choice C) is relevant but does not directly assess oxygenation levels. Checking skin color (choice D) can provide some information about oxygenation, but it is not as precise or direct as measuring oxygen saturation.
