Nursing Elites

1. The healthcare provider prescribes diagnostic tests for a client with pneumonia identified on a chest X-ray. Which diagnostic test should the nurse review for implementation to guide the most therapeutic treatment of pneumonia?

• A. Sputum culture and sensitivity
• B. Blood cultures
• C. Arterial blood gases (ABG)
• D. Computerized tomography (CT) of the chest

Correct answer: A

Rationale: Sputum culture and sensitivity is the most appropriate diagnostic test for pneumonia as it helps in identifying the causative organism, which is crucial for guiding the selection of the most effective antibiotic therapy. Blood cultures (choice B) are more useful in identifying systemic infections rather than pneumonia specifically. Arterial blood gases (ABG) (choice C) are helpful in assessing oxygenation but do not directly aid in identifying the causative organism. Computerized tomography (CT) of the chest (choice D) is useful for evaluating structural abnormalities in the lungs but is not the initial test of choice for diagnosing pneumonia.

2. A client with gastroesophageal reflux disease (GERD) has been experiencing severe reflux during sleep. Which recommendation by the nurse is most effective to assist the client?

• A. Losing weight.
• B. Decreasing caffeine intake.
• C. Avoiding large meals.
• D. Raising the head of the bed on blocks.

Correct answer: D

Rationale: The correct answer is to raise the head of the bed on blocks (reverse Trendelenburg position). This elevation helps reduce reflux by using gravity to keep stomach contents from flowing back into the esophagus during sleep. Losing weight (Choice A) could be beneficial in managing GERD, but it may not be as effective for immediate relief during sleep. Decreasing caffeine intake (Choice B) and avoiding large meals (Choice C) are also valuable recommendations to manage GERD; however, they may not specifically address the issue of reflux during sleep as directly and effectively as elevating the head of the bed.

3. The nurse is caring for a patient whose serum sodium level is 140 mEq/L and serum potassium level is 5.4 mEq/L. The nurse will contact the patient’s provider to discuss an order for

• A. a low-potassium diet.
• B. intravenous sodium bicarbonate.
• C. Kayexalate and sorbitol.
• D. salt substitutes.

Correct answer: A

Rationale: In the scenario presented, the patient is experiencing mild hyperkalemia with a potassium level of 5.4 mEq/L. The appropriate intervention for mild hyperkalemia is a low-potassium diet to restrict potassium intake. This helps in managing and preventing further elevation of potassium levels. Intravenous sodium bicarbonate is not indicated as the patient's sodium level is normal at 140 mEq/L. Kayexalate, a cation-exchange resin, is typically used for severe hyperkalemia to promote potassium excretion. Salt substitutes, which often contain potassium chloride, should be avoided in patients with hyperkalemia as they can exacerbate the condition by increasing potassium levels further.

4. During CPR, when attempting to ventilate a client's lungs, the nurse notes that the chest is not moving. What action should the nurse take first?

• A. Use a laryngoscope to check for a foreign body lodged in the airway.
• B. Reposition the head to ensure that the airway is properly opened.
• C. Turn the client to the side and administer three back blows.
• D. Perform a finger sweep of the mouth to clear any obstructions.

Correct answer: B

Rationale: The most common reason for inadequate lung aeration during CPR is the incorrect positioning of the head, leading to airway obstruction. Therefore, the initial action should be to reposition the head to open the airway properly and attempt to ventilate again. Using a laryngoscope to check for foreign bodies in the airway (Choice A) is not the first step and could delay crucial interventions. Turning the client to the side and administering back blows (Choice C) is not indicated in this scenario as the focus is on ventilating the lungs. Performing a finger sweep of the mouth (Choice D) is not recommended as it may push obstructions further into the airway during CPR.

5. A client has just had a central line catheter placed that is specific for hemodialysis. What is the most appropriate action by the nurse?

• A. Use the catheter for the next laboratory blood draw.
• B. Monitor the central venous pressure through this line.
• C. Access the line for the next intravenous medication.
• D. Place a heparin or heparin/saline dwell after hemodialysis.

Correct answer: D

Rationale: The most appropriate action for the nurse after a central line catheter placement for hemodialysis is to place a heparin or heparin/saline dwell after hemodialysis treatment. This helps prevent clot formation in the line and maintain patency for future use. Using the catheter for blood draws is not recommended as it may increase the risk of infection. Monitoring central venous pressure is not indicated with this type of catheter. Accessing the line for medications is also not recommended to prevent complications and ensure the line is solely used for hemodialysis purposes.
