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 diabetes mellitus is experiencing diabetic ketoacidosis (DKA). What laboratory result should the nurse monitor closely?

• A. White blood cell count of 15,000.
• B. Blood glucose level of 320 mg/dL.
• C. Sodium level of 145 mEq/L.
• D. Serum creatinine level of 1.0 mg/dL.

Correct answer: B

Rationale: A blood glucose level of 320 mg/dL indicates the need for insulin to manage diabetic ketoacidosis.

3. The nurse is assessing a client with a history of schizophrenia who reports feeling sedated after starting a new antipsychotic medication. Which intervention is most appropriate?

• A. Reassure the client that sedation will subside with continued use
• B. Instruct the client to take the medication at bedtime
• C. Teach the client to take the medication with food
• D. Consult the healthcare provider to reduce the dosage

Correct answer: B

Rationale: Instructing the client to take the medication at bedtime is the most appropriate intervention. Taking antipsychotic medications at bedtime can help reduce the impact of sedation on the client's daily activities. This approach allows the client to sleep through the sedative effects. Choice A is incorrect because just reassuring the client may not address the immediate issue of sedation. Choice C is incorrect as taking the medication with food does not directly address the sedation concern. Choice D is not the first-line intervention; adjusting the dosage should be done by the healthcare provider after assessing the client's response to the medication.

4. A client with a history of chronic kidney disease presents with increased swelling and shortness of breath. What is the nurse's priority action?

• A. Administer oxygen at 2 liters per nasal cannula.
• B. Administer a diuretic as prescribed.
• C. Monitor the client's vital signs.
• D. Reposition the client to improve lung expansion.

Correct answer: B

Rationale: The correct answer is to administer a diuretic as prescribed. In a client with chronic kidney disease experiencing increased swelling and shortness of breath, the priority action is to address fluid retention. Administering a diuretic helps reduce fluid overload, alleviate symptoms, and prevent complications associated with fluid buildup. Option A is not the priority in this situation as addressing fluid retention takes precedence over providing oxygen. While monitoring vital signs is important, it is secondary to addressing the underlying cause of symptoms. Repositioning the client may help with comfort but does not directly address the fluid overload seen in chronic kidney disease.

5. A client with a tracheostomy develops copious, thick secretions. What is the nurse's priority action?

• A. Increase the client's fluid intake.
• B. Perform tracheal suctioning.
• C. Administer a mucolytic agent.
• D. Increase the humidity of the oxygen source.

Correct answer: D

Rationale: The correct answer is to increase the humidity of the oxygen source. This action helps thin thick secretions, making them easier to clear from the tracheostomy tube. Increasing fluid intake (Choice A) can be beneficial in some cases but addressing humidity is more specific to managing thick secretions in a client with a tracheostomy. Tracheal suctioning (Choice B) should be done after attempting to thin the secretions with increased humidity. Administering a mucolytic agent (Choice C) is a possible intervention but typically comes after addressing humidity and before resorting to suctioning to avoid unnecessary invasiveness.
