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 has been receiving hydromorphone every six hours for four days. What assessment should the nurse prioritize?

• A. Increase the dosage of the medication.
• B. Auscultate bowel sounds.
• C. Monitor the client's blood pressure.
• D. Check the client's respiratory rate.

Correct answer: B

Rationale: The correct answer is B. Hydromorphone can cause constipation, a common side effect of opioids. Therefore, it is crucial to auscultate bowel sounds to monitor for signs of decreased gastrointestinal motility. Monitoring blood pressure (choice C) and respiratory rate (choice D) are important but not the priority in this scenario as constipation is a common issue with opioid use. Increasing the dosage of the medication (choice A) is not appropriate without assessing the client's bowel function first.

3. A male client with HIV on saquinavir and other antiretrovirals reports increased hunger and thirst but weight loss. Which action should the nurse take?

• A. Use a glucometer to assess capillary glucose.
• B. Explain to the client that an increased dose of medication is needed.
• C. Reassure the client that weight will improve as viral load decreases.
• D. Teach the client how to measure his weight accurately.

Correct answer: A

Rationale: Increased thirst and hunger while losing weight may indicate hyperglycemia, a common side effect of saquinavir and other antiretrovirals. Using a glucometer to assess capillary glucose levels is essential to evaluate for hyperglycemia. Choice B is incorrect because increasing the dose of medication without assessing blood glucose levels can be dangerous. Choice C is incorrect because weight loss may not necessarily improve with viral load reduction and doesn't address the immediate concern of hyperglycemia. Choice D is irrelevant to the presenting symptoms and should not be a priority over assessing for hyperglycemia.

4. A client receiving total parenteral nutrition (TPN) reports nausea and dizziness. What action should the nurse take first?

• A. Check the client's blood glucose level.
• B. Check the client's vital signs and blood pressure.
• C. Decrease the infusion rate of TPN.
• D. Administer antiemetic medication as prescribed.

Correct answer: B

Rationale: When a client receiving total parenteral nutrition (TPN) reports symptoms like nausea and dizziness, the first action the nurse should take is to check the client's vital signs and blood pressure. This assessment helps determine the client's overall stability and can provide crucial information to guide further interventions. Checking the blood glucose level (Choice A) may be relevant but is not the priority in this situation. Decreasing the infusion rate of TPN (Choice C) may be necessary but should be based on assessment findings. Administering antiemetic medication (Choice D) should not be the initial action without first assessing the client's vital signs.

5. A client with hyperkalemia is receiving insulin and glucose. Which laboratory value should the nurse monitor closely?

• A. Monitor the client's blood glucose level.
• B. Monitor the client's sodium level.
• C. Monitor the client's calcium level.
• D. Monitor the client's potassium level.

Correct answer: D

Rationale: The correct answer is to monitor the client's potassium level. When administering insulin and glucose in hyperkalemia, the aim is to shift potassium from the bloodstream into the cells, lowering elevated levels. Therefore, monitoring potassium levels closely is essential to prevent hypokalemia or further complications. Monitoring blood glucose levels (Choice A) is important but not the priority in this scenario. Monitoring sodium (Choice B) and calcium levels (Choice C) is not directly related to the treatment of hyperkalemia with insulin and glucose.
