Nursing Elites

1. A client with a history of myocardial infarction (MI) is admitted with chest pain. Which laboratory test should the nurse expect to be ordered to determine if the client is experiencing another MI?

• A. Troponin
• B. Myoglobin
• C. CK-MB
• D. C-reactive protein

Correct answer: A

Rationale: Troponin is the most specific and sensitive laboratory test for detecting myocardial infarction (MI). It is released when there is damage to the heart muscle, making it a valuable marker for diagnosing another MI. Myoglobin and CK-MB can also be elevated in MI, but troponin is preferred due to its higher specificity. C-reactive protein is a marker of inflammation and not specific to MI.

2. A client is in the radiology department at 0900 when the prescription for levofloxacin (Levaquin) 500 mg IV q24h is scheduled to be administered. The client returns to the unit at 1300. What is the best intervention for the nurse to implement?

• A. Contact the healthcare provider and complete a medication variance form.
• B. Administer the Levaquin at 1300 and resume the 0900 schedule the next day.
• C. Notify the charge nurse and complete an incident report to explain the missed dose.
• D. Give the missed dose at 1300 and change the schedule to administer daily at 1300.

Correct answer: D

Rationale: To maintain a therapeutic level of medication, the nurse should administer the missed dose as soon as possible and adjust the administration schedule to prevent dangerously high levels of the drug in the bloodstream (D). It is important to document the reason for the delayed dose. Contacting the healthcare provider and completing a medication variance form (A) may cause unnecessary delays. Notifying the charge nurse and completing an incident report (C) should be done after addressing the immediate medication administration issue. Administering the medication at 1300 and resuming the 0900 schedule the next day (B) could lead to suboptimal therapeutic levels and potential complications.

3. An older adult who recently began self-administration of insulin calls the nurse daily to review the steps that should be taken when giving an injection. The nurse has assessed the client's skills during two previous office visits and knows that the client is capable of giving the daily injection. Which response by the nurse is likely to be most helpful in encouraging the client to assume total responsibility for the daily injections?

• A. I know you are capable of giving yourself the insulin.
• B. Giving yourself the injection seems to make you nervous.
• C. When I watched you give yourself the injection, you did it correctly.
• D. Tell me what you want me to do to help you give yourself the injection at home.

Correct answer: C

Rationale: Choice C is the correct answer because focusing on the client's demonstrated ability to self-administer the injection is likely to reinforce his level of competence without sounding punitive. By acknowledging the client's correct performance during the self-injection, the nurse can boost the client's confidence, encouraging him to assume total responsibility for the daily injections. Choices A, B, and D do not directly highlight the client's competence in self-administration, which may not be as effective in promoting independent self-care.

4. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which intervention should the nurse implement first?

• A. Administer regular insulin IV.
• B. Administer IV fluids at 250 ml/hr.
• C. Administer sodium bicarbonate IV push.
• D. Administer furosemide (Lasix) IV push.

Correct answer: A

Rationale: Administering regular insulin IV (A) is the initial intervention for a client with diabetic ketoacidosis (DKA) to rapidly reduce blood glucose levels. This is vital in reversing the ketosis and acidosis seen in DKA. Administering IV fluids (B) helps to correct dehydration and electrolyte imbalances. Administering sodium bicarbonate (C) and furosemide (D) may be necessary depending on the client's condition, but insulin administration takes precedence in the management of DKA.

5. The nurse is providing discharge teaching to a client with a new prescription for warfarin (Coumadin). Which dietary instruction should the nurse include?

• A. Avoid foods high in vitamin K
• B. Increase intake of leafy green vegetables
• C. Consume a consistent amount of foods high in potassium
• D. Limit intake of high-protein foods

Correct answer: A

Rationale: The correct dietary instruction for a client taking warfarin is to avoid foods high in vitamin K. Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors. Consuming foods high in vitamin K, such as leafy green vegetables, can antagonize the effects of warfarin, potentially leading to treatment inefficacy or fluctuations in anticoagulation levels. Therefore, clients on warfarin therapy should be advised to avoid foods high in vitamin K to maintain the effectiveness of the medication. Choices B, C, and D are incorrect because increasing leafy green vegetables (choice B) would introduce more vitamin K, consuming a consistent amount of foods high in potassium (choice C) is not directly related to warfarin therapy, and limiting high-protein foods (choice D) is not a specific concern for clients on warfarin therapy.
