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 nurse is performing CPR on an adult who went into cardiopulmonary arrest. Another nurse enters the room in response to the call. After checking the client's pulse and respirations, what should be the function of the second nurse?

• A. Relieve the nurse performing CPR
• B. Go get the code cart
• C. Participate with the compressions or breathing
• D. Validate the client's advanced directive

Correct answer: C

Rationale: The correct answer is C. The second nurse should assist with compressions or breathing to ensure the patient receives adequate care during CPR. This immediate intervention is crucial in maintaining blood circulation and oxygenation to vital organs. Choice A is incorrect because simply relieving the nurse performing CPR may lead to a delay in essential life-saving measures. Choice B is incorrect as the primary focus should be on providing direct assistance rather than fetching equipment. Choice D is incorrect as validating the client's advanced directive is not the priority in this emergency situation.

3. When a pediatric client is taking the beta-adrenergic blocking agent propranolol, what signs of overdose should the nurse instruct the parents to report?

• A. Seizures
• B. Increased respiratory rate
• C. Bradycardia
• D. Irritability

Correct answer: C

Rationale: When a pediatric client is taking propranolol, the nurse should instruct the parents to report signs of overdose, including bradycardia. Propranolol is a beta-blocker that can lead to dangerously slow heart rate as a sign of overdose. While increased respiratory rate, seizures, and irritability may occur in some cases, bradycardia is the most critical symptom indicating an overdose of this medication.

4. A client with chronic kidney disease is prescribed erythropoietin. What is the nurse's priority action?

• A. Monitor the client's hemoglobin and hematocrit.
• B. Monitor the client's blood pressure.
• C. Assess the client for signs of infection.
• D. Monitor the client for signs of bleeding.

Correct answer: A

Rationale: The correct answer is A: 'Monitor the client's hemoglobin and hematocrit.' When a client with chronic kidney disease is prescribed erythropoietin, the nurse's priority action is to monitor the client's hemoglobin and hematocrit. Erythropoietin stimulates red blood cell production, so monitoring these lab values helps evaluate the effectiveness of erythropoietin in treating anemia. Monitoring the client's blood pressure (choice B) is important but not the priority in this scenario. Assessing the client for signs of infection (choice C) is important but not the priority related to the prescription of erythropoietin. Monitoring the client for signs of bleeding (choice D) is relevant but not the priority action when erythropoietin is prescribed.

5. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who has been experiencing increasing shortness of breath. Which finding requires immediate intervention?

• A. A respiratory rate of 26 breaths per minute
• B. Use of accessory muscles for breathing
• C. Barrel chest appearance
• D. A pulse oximetry reading of 88%

Correct answer: D

Rationale: A pulse oximetry reading of 88% indicates hypoxemia, which requires immediate intervention to improve oxygenation. Hypoxemia can lead to serious complications if not addressed promptly. While a respiratory rate of 26 breaths per minute and the use of accessory muscles for breathing are concerning in COPD, they do not indicate an immediate life-threatening situation. Similarly, a barrel chest appearance is a common finding in COPD and does not require urgent intervention compared to the critical need to address hypoxemia.
