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 with hypertension is prescribed hydrochlorothiazide. What teaching should the nurse provide?

• A. Take the medication in the morning to avoid frequent urination at night.
• B. Increase fluid intake to prevent dehydration.
• C. Avoid potassium-rich foods, such as bananas and oranges.
• D. Monitor the client’s potassium levels weekly.

Correct answer: B

Rationale: The correct teaching for a client prescribed hydrochlorothiazide is to increase fluid intake to prevent dehydration. Hydrochlorothiazide is a diuretic that can lead to fluid loss and electrolyte imbalances, so adequate fluid intake is crucial. Choice A is incorrect because hydrochlorothiazide is typically taken in the morning to avoid nighttime urination. Choice C is incorrect as potassium-rich foods should not be avoided but monitored, as hydrochlorothiazide can cause potassium loss. Choice D is incorrect as potassium levels should be monitored regularly, but not necessarily weekly, unless indicated by the healthcare provider.

3. The nurse is providing discharge instructions to a client who has had a stroke. Which intervention should the nurse recommend to prevent aspiration during meals?

• A. Encourage the client to take large bites of food
• B. Advise the client to eat quickly to prevent fatigue
• C. Offer the client thin liquids with meals
• D. Instruct the client to sit upright while eating

Correct answer: D

Rationale: Instructing the client to sit upright while eating is crucial to prevent aspiration in stroke clients. This position helps in safe swallowing and reduces the risk of food or liquid entering the airway. Encouraging the client to take large bites of food (Choice A) can increase the risk of choking and aspiration. Advising the client to eat quickly (Choice B) may lead to fatigue and compromise safe swallowing. Offering thin liquids (Choice C) can also increase the risk of aspiration in stroke clients, as thicker liquids are usually recommended to prevent aspiration.

4. A client with a head injury reports severe nausea. What is the nurse's priority action?

• A. Administer anti-nausea medication as prescribed.
• B. Prepare the client for a CT scan.
• C. Elevate the head of the bed and provide an emesis basin.
• D. Notify the healthcare provider immediately.

Correct answer: D

Rationale: Severe nausea in a client with a head injury may be a sign of increased intracranial pressure. The nurse should notify the healthcare provider immediately to ensure timely intervention, as increased pressure can lead to further complications such as brain herniation. Administering anti-nausea medication or preparing for a CT scan may delay necessary treatment for the underlying cause of the nausea, which could be related to the head injury. Elevating the head of the bed and providing an emesis basin may help manage symptoms but should not be the priority over addressing the potential increase in intracranial pressure.

5. The nurse reviews the diagnostic tests prescribed for a client with a positive skin test. Which subjective findings reported by the client support the diagnosis of tuberculosis?

• A. Mucopurulent cough and night sweats
• B. Fatigue and headache
• C. Persistent cough and weight gain
• D. Weight loss and fever

Correct answer: A

Rationale: A mucopurulent cough and night sweats are hallmark signs of active tuberculosis. These symptoms are key indicators of TB as the combination of a productive cough with night sweats is highly suggestive of the disease. Fatigue and headache (choice B) are nonspecific symptoms that can occur in many conditions and are not specific to TB. Persistent cough and weight gain (choice C) are not typical findings in tuberculosis. Weight loss and fever (choice D) can be present in TB, but the specific combination of mucopurulent cough and night sweats is more specific to the diagnosis.
