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. The nurse is caring for a 24-month-old toddler who has sensory sensitivity, difficulty engaging in social interactions, and has not yet spoken two-word phrases. Which assessment should the nurse administer?

• A. Peabody Picture Vocabulary Test
• B. The Modified Checklist for Autism in Toddlers (M-CHAT)
• C. Wechsler Preschool and Primary Scale of Intelligence
• D. Denver Developmental Screening Test

Correct answer: B

Rationale: The Modified Checklist for Autism in Toddlers (M-CHAT) is specifically designed to screen for autism spectrum disorders in young children. It is appropriate for this child, given the signs of social and communication delays. The Peabody Picture Vocabulary Test (Choice A) assesses receptive vocabulary and may not capture the social and communication aspects seen in autism. The Wechsler Preschool and Primary Scale of Intelligence (Choice C) measures cognitive ability and may not address the social and communication delays. The Denver Developmental Screening Test (Choice D) is a broad developmental assessment tool, but the M-CHAT is more specific to screening for autism in this case.

3. A client with bipolar disorder is prescribed lithium. What should the nurse teach the client about lithium toxicity?

• A. Take the medication with meals to prevent gastrointestinal upset.
• B. Report any symptoms of nausea, vomiting, or diarrhea.
• C. Monitor lithium levels regularly and maintain hydration.
• D. Avoid taking nonsteroidal anti-inflammatory drugs (NSAIDs) while on lithium.

Correct answer: D

Rationale: The correct answer is D. Clients taking lithium should avoid NSAIDs as they can increase lithium levels leading to toxicity. It is essential to monitor lithium levels regularly and maintain hydration to prevent toxicity. Reporting symptoms like nausea, vomiting, or diarrhea is important, but the key teaching point regarding lithium toxicity is to avoid NSAIDs.

4. After administering a proton pump inhibitor, which action should the nurse take to evaluate the effectiveness of the medication?

• A. Monitor gastrointestinal pain
• B. Ask the client about pain levels
• C. Check the client's vital signs
• D. Assess for signs of bleeding

Correct answer: B

Rationale: The correct answer is to ask the client about pain levels. Proton pump inhibitors (PPIs) work by reducing stomach acid to alleviate gastrointestinal pain. By inquiring about the client's pain experience, the nurse can directly assess the effectiveness of the medication. Monitoring bowel movements (Choice A) is not directly related to evaluating the effectiveness of a PPI. Checking vital signs (Choice C) may not reflect the medication's effectiveness in reducing stomach acid. Assessing for signs of bleeding (Choice D) is important but not the most direct way to evaluate the effectiveness of a PPI.

5. A client with congestive heart failure is prescribed digoxin. What symptom indicates digoxin toxicity?

• A. Monitor for muscle weakness and fatigue.
• B. Monitor for increased appetite and weight gain.
• C. Monitor for nausea and vomiting.
• D. Monitor for blurred vision or seeing yellow halos around objects.

Correct answer: D

Rationale: Corrected Rationale: Blurred vision or seeing yellow halos around objects are signs of digoxin toxicity, which can be life-threatening. These symptoms indicate an overdose of digoxin, requiring immediate medical attention. Muscle weakness and fatigue (Choice A) are not typically associated with digoxin toxicity. Increased appetite and weight gain (Choice B) are not indicative of digoxin toxicity either. Nausea and vomiting (Choice C) are common side effects of digoxin but are not specific signs of toxicity. Therefore, the correct answer is to monitor for blurred vision or seeing yellow halos around objects.
