Nursing Elites

1. A patient with a pleural effusion is scheduled for a thoracentesis. Which action should the nurse take to prepare the patient for the procedure?

• A. Start a peripheral IV line to administer any necessary sedative drugs.
• B. Position the patient sitting upright on the edge of the bed and leaning forward.
• C. Obtain a collection device to hold a reasonable amount of pleural fluid for extraction.
• D. Remove the water pitcher and remind the patient not to eat or drink anything for 6 hours.

Correct answer: B

Rationale: The correct action for the nurse to take in preparing a patient for a thoracentesis is to position the patient sitting upright on the edge of the bed and leaning forward. This position helps fluid accumulate at the lung bases, making it easier to locate and remove. Sedation is not usually required for a thoracentesis, so starting an IV line for sedative drugs is unnecessary. Additionally, there are no restrictions on oral intake before the procedure since the patient is not sedated or unconscious. A large collection device to hold 2 to 3 liters of pleural fluid at one time is excessive as usually only 1000 to 1200 mL of pleural fluid is removed to avoid complications like hypotension, hypoxemia, or pulmonary edema. Therefore, the correct choice is to position the patient upright for the procedure.

2. Which oxygen delivery system would provide the highest concentrations of oxygen to the client?

• A. Venturi mask
• B. Partial rebreather mask
• C. Non-rebreather mask
• D. Simple face mask

Correct answer: C

Rationale: The correct answer is the non-rebreather mask. This oxygen delivery system has a one-way valve that prevents exhaled air from entering the reservoir bag and one or more valves covering the air holes on the face mask itself to prevent the inhalation of room air but allow exhalation of air. When a tight seal is achieved around the mask, up to 100% of oxygen is available. Choice A, the Venturi mask, delivers precise oxygen concentrations but not as high as the non-rebreather mask. Choice B, the partial rebreather mask, allows the client to rebreathe some exhaled air, resulting in lower oxygen concentrations than the non-rebreather mask. Choice D, the simple face mask, delivers low to moderate oxygen concentrations and is not designed to provide the highest concentrations like the non-rebreather mask.

3. Following mitral valve replacement surgery, a client develops PVCs. The healthcare provider orders a bolus of Lidocaine followed by a continuous Lidocaine infusion at a rate of 2 mg/minute. The IV solution contains 2 grams of Lidocaine in 500 mL of D5W. The infusion pump delivers 60 microdrops/mL. What rate would deliver 4 mg of Lidocaine per minute?

• A. 60 microdrops/minute
• B. 20 microdrops/minute
• C. 30 microdrops/minute
• D. 40 microdrops/minute

Correct answer: A

Rationale: To calculate the rate needed to deliver 4 mg/minute of Lidocaine, first, convert 2 grams to milligrams: 2 grams = 2000 mg. Then, set up a ratio between the total amount of Lidocaine (2000 mg) and the total volume of IV solution (500 mL): 2000 mg / 500 mL = 4 mg / x mL. Solving for x, x = 1 mL. Since the infusion pump delivers 60 microdrops per mL, multiplying by 60 microdrops/mL gives the correct rate of 60 microdrops/minute. This rate ensures the desired 4 mg of Lidocaine is delivered per minute. Choices B, C, and D are incorrect as they do not align with the accurate calculation based on the provided information.

4. A patient has acute bronchitis with a nonproductive cough and wheezes. Which topic should the nurse plan to include in the teaching plan?

• A. Purpose of antibiotic therapy
• B. Ways to limit oral fluid intake
• C. Appropriate use of cough suppressants
• D. Safety concerns with home oxygen therapy

Correct answer: C

Rationale: In acute bronchitis, which is often viral, cough suppressants can help manage the symptoms of a nonproductive cough. Antibiotics are not typically used in acute bronchitis unless there are systemic symptoms indicating a bacterial infection. Limiting oral fluid intake is not recommended; in fact, maintaining adequate hydration is important. Safety concerns with home oxygen therapy may not be directly relevant to the management of acute bronchitis.

5. The nurse is caring for a client with a serum potassium level of 3.5 mEq/L. The client is placed on a cardiac monitor and receives 40 mEq potassium chloride in 1000 ml of 5% dextrose in water IV. Which of the following EKG patterns indicates to the nurse that the infusions should be discontinued?

• A. Narrowed QRS complex
• B. Shortened "PR"? interval
• C. Tall peaked "T"? waves
• D. Prominent "U"? waves

Correct answer: C

Rationale: A tall peaked T wave is a characteristic EKG pattern associated with hyperkalemia. Hyperkalemia refers to high levels of potassium in the blood, which can lead to cardiac arrhythmias and other serious complications. Tall peaked T waves are a red flag for potential cardiac issues and can indicate the need to discontinue potassium infusions. The other choices, such as narrowed QRS complex, shortened "PR"? interval, and prominent "U"? waves, are not typically associated with hyperkalemia. Therefore, recognizing tall peaked T waves is crucial for the nurse to take prompt action in managing the client's condition.
