Nursing Elites

1. What is the most important action for preventing infection in a client with a central venous catheter?

• A. Changing the catheter dressing every 72 hours.
• B. Flushing the catheter with heparin solution daily.
• C. Ensuring the catheter is clamped when not in use.
• D. Maintaining sterile technique when handling the catheter.

Correct answer: D

Rationale: Maintaining sterile technique when handling a central venous catheter is crucial in preventing infections. This action helps minimize the introduction of pathogens into the catheter site, reducing the risk of contamination and subsequent infection. Changing the catheter dressing every 72 hours, while important, does not directly address the prevention of infection at the insertion site. Flushing the catheter with heparin solution daily helps prevent occlusion but does not primarily focus on infection prevention. Ensuring the catheter is clamped when not in use is essential for preventing air embolism but does not directly relate to infection control.

2. While auscultating the anterior chest of a newly admitted patient, what would the nurse expect to hear?

• A. Normal breathing sounds
• B. Wheezing
• C. Crackles
• D. Stridor

Correct answer: A

Rationale: When auscultating the chest, normal breathing sounds are expected in a healthy individual. Wheezing is a high-pitched whistling sound that indicates narrowed airways and is often heard in conditions like asthma. Crackles are fine, crackling sounds heard on inspiration or expiration and are associated with conditions like pneumonia or heart failure. Stridor is a high-pitched, harsh sound heard during inspiration due to upper airway obstruction. Therefore, choices B, C, and D indicate abnormal respiratory findings, while choice A signifies normal breathing sounds.

3. The healthcare provider prescribes the diuretic metolazone (Zaroxolyn) 7.5 mg PO. Zaroxolyn is available in 5 mg tablets. How much should the LPN/LVN plan to administer?

• A. 1/2 tablet.
• B. 1 tablet.
• C. 1 1/2 tablets.
• D. 2 tablets.

Correct answer: C

Rationale: To administer 7.5 mg of metolazone (Zaroxolyn), the LPN/LVN should plan to give 1 1/2 tablets since each tablet contains 5 mg. Choice A (1/2 tablet) would not provide the full prescribed dose. Choice B (1 tablet) would only deliver 5 mg, which is less than the prescribed dose. Choice D (2 tablets) would exceed the prescribed dose, resulting in 10 mg instead of the required 7.5 mg. Therefore, the correct answer is to administer 1 1/2 tablets to achieve the prescribed 7.5 mg.

4. A client is receiving a blood transfusion. The client reports flank pain, and the nurse notes reddish-brown urine in the client's urinary catheter bag. The nurse recognizes these manifestations as which of the following types of transfusion reactions?

• A. Hemolytic
• B. Allergic
• C. Febrile
• D. Transfusion-related acute lung injury (TRALI)

Correct answer: A

Rationale: The correct answer is A: Hemolytic. Hemolytic reactions can lead to flank pain and hemoglobinuria, as the body breaks down the transfused red blood cells. In hemolytic reactions, the immune system attacks and destroys the transfused red blood cells, causing the release of hemoglobin into the bloodstream and urine. This results in reddish-brown urine, indicating hemoglobinuria. Allergic reactions typically present with symptoms like itching, hives, or rash. Febrile reactions are characterized by fever, chills, and rigors. TRALI is a rare but serious transfusion reaction that manifests as acute respiratory distress following a transfusion, not flank pain and hemoglobinuria.

5. Before starting an intensive exercise program, what instruction is most important for the nurse to provide to the client?

• A. Be sure to have a complete physical examination before beginning your planned exercise program.
• B. Be careful that the exercise program doesn't simply add to your stress level, making you want to eat more.
• C. Increased exercise helps to reduce stress, so you may not need to spend money on a stress management class.
• D. Make sure to monitor your weight loss regularly to provide a sense of accomplishment and motivation.

Correct answer: A

Rationale: Before starting an intensive exercise program, it is crucial for the client to have a complete physical examination. This examination ensures that the client is physically fit to engage in such activities and helps in identifying any underlying health issues that could be exacerbated by the exercise regimen. Choice B is incorrect because it focuses on stress levels related to eating habits rather than the importance of a physical examination for safety. Choice C is incorrect as exercise and stress management classes can complement each other rather than being mutually exclusive. Choice D is incorrect as monitoring weight loss, while important, is not as critical as ensuring the client's physical readiness for the exercise program.
