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 being educated on lifestyle changes by a nurse. Which recommendation is the most important to reduce blood pressure?

• A. Increase water intake
• B. Avoid alcohol consumption
• C. Exercise regularly
• D. Reduce sodium intake

Correct answer: D

Rationale: Reducing sodium intake is crucial in managing hypertension as high sodium levels can lead to fluid retention and increased blood pressure. While increasing water intake is beneficial for overall health, reducing sodium has a more significant impact on blood pressure. Regular exercise is important for cardiovascular health but does not have as direct an impact on blood pressure as sodium reduction. Avoiding alcohol is also important, but in terms of managing blood pressure, reducing sodium intake takes precedence.

3. A client with a urinary tract infection (UTI) is prescribed ciprofloxacin. What client teaching is essential?

• A. Increase fluid intake to prevent crystalluria.
• B. Take the medication with meals to prevent GI upset.
• C. Avoid sunlight exposure while taking the medication.
• D. Report any changes in the color of urine.

Correct answer: A

Rationale: The correct answer is to increase fluid intake to prevent crystalluria, a potential side effect of ciprofloxacin. Crystalluria is the formation of crystals in the urine, which can be reduced by maintaining adequate hydration. Choice B is incorrect because ciprofloxacin can be taken with or without food. Choice C is incorrect as avoiding sunlight exposure is more relevant for medications that cause photosensitivity, not typically a concern with ciprofloxacin. Choice D is less essential than choice A because while reporting changes in urine color is important, preventing crystalluria through adequate fluid intake is a higher priority.

4. The nurse is assessing a client with rheumatoid arthritis who is taking a nonsteroidal anti-inflammatory drug (NSAID). Which laboratory value should the nurse monitor?

• A. Potassium
• B. Hemoglobin
• C. Serum creatinine
• D. White blood cell count

Correct answer: C

Rationale: When a client with rheumatoid arthritis is taking NSAIDs, the nurse should monitor serum creatinine levels. NSAIDs can potentially cause kidney damage, so monitoring creatinine levels helps assess for renal impairment. While monitoring hemoglobin, potassium, and white blood cell count may also be relevant in some cases, serum creatinine is the priority due to the risk of renal complications associated with NSAID use.

5. During an initial assessment, a healthcare provider notes that a client has elevated blood pressure. Which of the following findings is considered a major risk factor for coronary artery disease?

• A. Elevated HDL cholesterol
• B. Low LDL cholesterol
• C. Elevated blood pressure
• D. Low triglyceride levels

Correct answer: C

Rationale: Elevated blood pressure is a significant risk factor for coronary artery disease because it increases the strain on the arteries, leading to potential damage and a higher risk of developing coronary artery disease. Elevated HDL cholesterol (Choice A) is actually considered beneficial as it helps reduce the risk of heart disease. Low LDL cholesterol (Choice B) is also beneficial as high levels of LDL are associated with an increased risk of coronary artery disease. Low triglyceride levels (Choice D) are not typically considered a major risk factor for coronary artery disease.
