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 type 1 diabetes is found unconscious with a blood glucose of 40 mg/dL. What is the nurse's priority intervention?

• A. Administer a 50% dextrose bolus intravenously.
• B. Administer glucagon intramuscularly.
• C. Provide oral glucose gel.
• D. Recheck the blood glucose level in 15 minutes.

Correct answer: A

Rationale: The correct answer is to administer a 50% dextrose bolus intravenously. In unconscious clients with hypoglycemia, IV dextrose rapidly raises the blood glucose level. Glucagon would be a slower option and is typically used if IV access is unavailable. Oral glucose gel is not appropriate for an unconscious client as it requires swallowing and may cause aspiration. Rechecking the blood glucose level in 15 minutes delays immediate treatment and could lead to further deterioration.

3. A young adult visits the clinic reporting symptoms associated with gastritis. Which information in the client's history is most important for the nurse to address in the teaching plan?

• A. Experiences occasional heartburn after eating spicy food
• B. Consumes 10 or more drinks of alcohol every weekend
• C. Reports frequent use of NSAIDs
• D. Has a history of peptic ulcers

Correct answer: B

Rationale: Excessive alcohol consumption is a major risk factor for gastritis and should be prioritized in the teaching plan. While spicy foods and NSAIDs can contribute to gastritis, alcohol consumption is the most significant factor that needs immediate lifestyle changes to prevent worsening of gastritis symptoms. Peptic ulcers, although relevant, are not as directly linked to exacerbating gastritis symptoms as alcohol consumption.

4. A client with a history of asthma reports using an albuterol inhaler more frequently than prescribed. Which action should the nurse take first?

• A. Notify the healthcare provider immediately
• B. Schedule a pulmonary function test
• C. Assess the client's respiratory status
• D. Instruct the client to decrease inhaler use

Correct answer: C

Rationale: Increased use of a rescue inhaler like albuterol may indicate worsening asthma symptoms. The nurse should first assess the client's respiratory status to determine the severity of the issue and the next steps in care. Option A is not the first action because assessing the client's condition should precede notifying the healthcare provider. Option B, scheduling a pulmonary function test, is not the priority as immediate assessment of the client's respiratory status is crucial. Instructing the client to decrease inhaler use should come after assessing the client's condition to ensure the appropriate intervention.

5. A teenager presents to the emergency department with palpitations after vaping at a party. The client is anxious, fearful, and hyperventilating. Which acid-base imbalance does the nurse anticipate the client developing?

• A. Metabolic alkalosis
• B. Respiratory alkalosis
• C. Respiratory acidosis
• D. Metabolic acidosis

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. Hyperventilation from anxiety or fear causes an excessive loss of CO2, leading to respiratory alkalosis. This shift in pH results from the rapid, shallow breathing that reduces the level of carbon dioxide in the blood. Respiratory acidosis would occur in cases of poor ventilation or CO2 retention, while metabolic acidosis/alkalosis relates to disturbances in bicarbonate, not breathing patterns. Therefore, in this case, the client's hyperventilation due to anxiety would likely result in respiratory alkalosis, making option B the correct choice.
