Nursing Elites

1. Which electrolyte imbalance is most concerning for a patient on loop diuretics?

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

Correct answer: A

Rationale: The correct answer is hypokalemia. Loop diuretics can cause potassium depletion leading to hypokalemia, which is particularly concerning as it can result in cardiac arrhythmias. Hyponatremia (choice B) is not typically associated with loop diuretics. Hyperkalemia (choice C) is less common in patients on loop diuretics. Hypercalcemia (choice D) is not a typical electrolyte imbalance associated with loop diuretics.

2. 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.

3. What is the appropriate action for a patient experiencing a severe allergic reaction?

• A. Administer epinephrine
• B. Administer antihistamines
• C. Administer corticosteroids
• D. Administer oxygen

Correct answer: A

Rationale: The correct answer is to administer epinephrine. Epinephrine is the first-line treatment for severe allergic reactions as it helps reverse the symptoms rapidly by constricting blood vessels, increasing heart rate, and opening airways. Antihistamines (Choice B) may help with mild allergic reactions but are not effective for severe cases. Corticosteroids (Choice C) are used to reduce inflammation and are typically not the first-line treatment for acute severe allergic reactions. Administering oxygen (Choice D) may be necessary to support breathing in severe cases, but epinephrine is the primary treatment to reverse the allergic reaction symptoms.

4. How should a healthcare professional respond to a patient who is experiencing confusion after surgery?

• A. Administer oxygen
• B. Reposition the patient
• C. Encourage deep breathing exercises
• D. Perform a neurological exam

Correct answer: A

Rationale: Administering oxygen is the most appropriate initial response to a patient experiencing confusion after surgery. Confusion can be a sign of hypoxia, which is inadequate oxygen supply to the brain. Administering oxygen helps ensure that the patient is getting enough oxygen, addressing a potential cause of the confusion. Repositioning the patient, encouraging deep breathing exercises, or performing a neurological exam may be necessary depending on the situation, but addressing potential hypoxia should be the priority in a confused post-operative patient.

5. A nurse is planning care for a client who has a new prescription for a peripheral intravenous (IV) catheter. Which of the following actions should the nurse take to prevent infection?

• A. Shave the hair at the insertion site.
• B. Cleanse the site with povidone-iodine.
• C. Wear sterile gloves when changing the dressing.
• D. Change the IV site every 48 to 72 hours.

Correct answer: D

Rationale: The correct action to prevent infection when caring for a client with a new peripheral IV catheter is to change the IV site every 48 to 72 hours. Shaving the hair at the insertion site can actually increase the risk of infection by causing microabrasions in the skin. While cleansing the site with povidone-iodine is important before insertion, it is not necessary to continue doing so once the IV is in place. Wearing sterile gloves when changing the dressing is crucial for maintaining aseptic technique but does not directly prevent infection related to the IV site itself.
