Nursing Elites

1. The nurse is caring for a client with a suspected myocardial infarction (MI). Which laboratory test result is most indicative of a recent MI?

• A. Elevated troponin levels
• B. Increased white blood cell count
• C. Increased lactate dehydrogenase (LDH)
• D. Elevated C-reactive protein (CRP)

Correct answer: A

Rationale: Elevated troponin levels are the most specific and sensitive indicator of myocardial infarction. Troponin levels increase within hours of an MI and remain elevated for several days. White blood cell count, lactate dehydrogenase (LDH), and C-reactive protein (CRP) are not specific markers for MI. An increased white blood cell count may indicate inflammation or infection, increased LDH levels can be seen in various conditions like liver disease or muscle injury, and elevated CRP is a general marker of inflammation rather than specific to MI.

2. A client receiving lactulose for hepatic encephalopathy needs evaluation. Which assessment should the nurse prioritize?

• A. Percussion of the abdomen.
• B. Blood glucose level.
• C. Serum electrolytes.
• D. Level of consciousness.

Correct answer: D

Rationale: The correct answer is D: Level of consciousness. When managing hepatic encephalopathy with lactulose, monitoring the client's level of consciousness is crucial as it is a key indicator of the therapeutic response to lactulose in reducing ammonia levels. Changes in consciousness can reflect the effectiveness of treatment and the progression of hepatic encephalopathy. Option A, percussion of the abdomen, is not directly related to evaluating the response to lactulose. Option B, blood glucose level, is important but not the priority in this context. Option C, serum electrolytes, while significant in liver disease, do not directly assess the impact of lactulose therapy on hepatic encephalopathy.

3. A 17-year-old adolescent reports flu-like symptoms and is brought to the emergency room. What intervention should the nurse implement first?

• A. Assess the client's temperature.
• B. Place a mask on the client.
• C. Obtain a chest X-ray per protocol.
• D. Determine the client's blood pressure.

Correct answer: B

Rationale: The correct answer is to place a mask on the client. This intervention is crucial in preventing the spread of infections like the flu, especially in a healthcare setting where the risk of transmission is high. Assessing the client's temperature (Choice A) can be important but is not the priority in this situation. Obtaining a chest X-ray (Choice C) and determining the client's blood pressure (Choice D) are not the immediate interventions needed for a 17-year-old reporting flu-like symptoms.

4. While changing a client's chest tube dressing, the nurse notes a cracking sensation when gentle pressure is applied to the skin at the insertion site. What is the best action for the nurse to take?

• A. Apply a pressure dressing around the chest tube site.
• B. Administer an oral antihistamine.
• C. Assess for allergies to topical cleaning agents.
• D. Measure the area of swelling and crackling.

Correct answer: D

Rationale: When a nurse observes crepitus around a chest tube site, it could indicate subcutaneous emphysema, a potentially serious condition where air gets trapped under the skin. Measuring the area of swelling and crackling is important as it helps monitor the progression of subcutaneous emphysema. Applying a pressure dressing (choice A) might not address the underlying cause and could potentially worsen the condition. Administering an oral antihistamine (choice B) is not indicated for crepitus at a chest tube site. Assessing for allergies to topical cleaning agents (choice C) is important but not the immediate priority when crepitus is observed.

5. A client is diagnosed with tuberculosis and is placed on isoniazid (INH) and rifampin (Rifadin). The nurse should emphasize the importance of

• A. Daily use of a bronchodilator
• B. The importance of taking medication as prescribed
• C. Decreasing salt intake
• D. Avoidance of direct sunlight

Correct answer: B

Rationale: The correct answer is B: The importance of taking medication as prescribed. In the treatment of tuberculosis, adherence to the prescribed medication regimen is crucial to effectively manage the infection and prevent the development of drug resistance. Choices A, C, and D are incorrect because bronchodilators, salt intake, and sunlight exposure are not directly related to the treatment of tuberculosis with isoniazid and rifampin.
