1. How should a healthcare professional care for a patient with a stage 2 pressure ulcer?

A. Clean the area with normal saline
B. Apply antibiotic ointment
C. Use a hydrocolloid dressing
D. Change the dressing daily

Correct answer: C

Rationale: Using a hydrocolloid dressing is the appropriate care for a stage 2 pressure ulcer because it provides a moist healing environment, promotes healing, and helps to prevent infection. Cleaning the area with normal saline (Choice A) is important but not the primary treatment for a stage 2 pressure ulcer. Applying antibiotic ointment (Choice B) may not be necessary unless there is a sign of infection. Changing the dressing daily (Choice D) may disrupt the healing process and is not recommended unless the dressing is soiled or compromised.

2. Which lab value should be monitored for a patient on warfarin therapy?

A. Monitor INR
B. Monitor potassium levels
C. Monitor platelet count
D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor INR for a patient on warfarin therapy. INR monitoring is crucial as it helps assess the therapeutic effectiveness and safety of warfarin. INR stands for International Normalized Ratio, and it measures the blood's ability to clot. Monitoring potassium levels (Choice B) is not specific to warfarin therapy. Monitoring platelet count (Choice C) is important but not the primary lab value for assessing warfarin therapy. Monitoring sodium levels (Choice D) is not directly related to warfarin therapy.

3. Which electrolyte imbalance is most concerning for a patient on furosemide?

A. Hypokalemia
B. Hyponatremia
C. Hyperkalemia
D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is hypokalemia. Furosemide, a loop diuretic, can lead to potassium loss through increased urinary excretion, making hypokalemia the most concerning electrolyte imbalance. Hyponatremia (Choice B) is not typically associated with furosemide use. Hyperkalemia (Choice C) is less likely due to furosemide's potassium-wasting effect. Hypercalcemia (Choice D) is not a common electrolyte imbalance seen with furosemide.

4. A nurse is caring for a client who is experiencing dysphagia. Which of the following interventions should the nurse implement?

A. Administer thickened liquids.
B. Provide small bites of food.
C. Encourage the client to eat quickly to avoid fatigue.
D. Have the client lie supine after meals.

Correct answer: A

Rationale: The correct intervention for a client with dysphagia is to administer thickened liquids. Thickened liquids help prevent aspiration, which is a common risk for clients with swallowing difficulties. Providing small bites of food (choice B) can help, but the priority is to modify the liquid consistency. Encouraging the client to eat quickly (choice C) is not recommended as it may increase the risk of aspiration and fatigue. Having the client lie supine after meals (choice D) can actually increase the risk of aspiration, especially in clients with dysphagia.

5. 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.
