Nursing Elites

1. Which electrolyte imbalance is common in patients receiving diuretics?

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

Correct answer: A

Rationale: The correct answer is Hypokalemia. Diuretics, such as furosemide, commonly cause potassium loss in patients, leading to hypokalemia. This electrolyte imbalance should be closely monitored to prevent complications like cardiac arrhythmias. Hypercalcemia (Choice B) is not typically associated with diuretic use. Hyponatremia (Choice C) involves low sodium levels and can occur in conditions like syndrome of inappropriate antidiuretic hormone secretion (SIADH) but is not directly caused by diuretics. Hypermagnesemia (Choice D) is an excess of magnesium, usually not a common electrolyte imbalance induced by diuretics.

2. A client with heart failure at risk for pulmonary edema should receive which intervention to improve oxygenation?

• A. Place the client in a supine position.
• B. Encourage the client to increase fluid intake.
• C. Elevate the client's legs when in bed.
• D. Administer oxygen via non-rebreather mask.

Correct answer: D

Rationale: Administering oxygen via a non-rebreather mask is the appropriate intervention for a client at risk for pulmonary edema as it helps improve oxygenation by delivering a high concentration of oxygen. Placing the client in a supine position can exacerbate pulmonary edema by increasing venous return to the heart, leading to fluid overload. Encouraging increased fluid intake is contraindicated in clients with heart failure and at risk for pulmonary edema, as it can worsen fluid accumulation. Elevating the client's legs when in bed is more appropriate for clients with conditions such as venous insufficiency or edema in the lower extremities, not for pulmonary edema.

3. 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.

4. When should healthcare professionals perform hand hygiene?

• A. Before and after patient contact
• B. Before and after performing procedures
• C. After using the restroom
• D. After touching contaminated surfaces

Correct answer: A

Rationale: Healthcare professionals should perform hand hygiene before and after patient contact to prevent the spread of infections. While choices B, C, and D are also important times to practice hand hygiene, they are not as crucial as before and after patient contact because patient contact poses a higher risk of transmitting infections.

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.
