Nursing Elites

1. A client with a diagnosis of myocardial infarction (MI) is being treated. Which laboratory value would be most concerning?

• A. Troponin level of 0.5 ng/mL
• B. Creatine kinase-MB (CK-MB) of 5.0 ng/mL
• C. Serum potassium of 4.5 mEq/L
• D. Blood glucose of 180 mg/dL

Correct answer: A

Rationale: A troponin level of 0.5 ng/mL is elevated, indicating myocardial damage, making it the most concerning finding in a client with a myocardial infarction (MI). Troponin is a highly specific marker for cardiac muscle damage, and elevated levels suggest ongoing injury to the heart muscle. While Creatine kinase-MB (CK-MB) is also a cardiac enzyme, troponin is more specific and sensitive for myocardial damage. Serum potassium and blood glucose levels are important parameters to monitor in MI patients, but in this scenario, the elevated troponin level takes precedence as it directly reflects cardiac injury.

2. The healthcare professional is preparing to administer potassium chloride intravenously to a client with hypokalemia. Which action is most important?

• A. Monitor the client's respiratory rate
• B. Check the client's urine output
• C. Administer the potassium chloride as a rapid IV push
• D. Dilute the potassium chloride in an appropriate IV solution

Correct answer: D

Rationale: The correct answer is to dilute the potassium chloride in an appropriate IV solution. Potassium chloride should never be administered as a rapid IV push as it can lead to severe complications, including cardiac arrhythmias. Diluting the medication and administering it slowly helps reduce the risk of adverse effects. Monitoring the client's respiratory rate (Choice A) and checking urine output (Choice B) are important aspects of patient assessment but not the most crucial when administering potassium chloride. Administering potassium chloride as a rapid IV push (Choice C) is dangerous and can result in serious harm to the client.

3. A post-op nurse has an indwelling catheter in place for gravity drainage. The nurse notes that the client's urine bag has been empty for 2 hours. The first action the nurse should take is to:

• A. Check to see if the tubing is kinked.
• B. Increase the IV fluid rate.
• C. Check the catheter insertion site.
• D. Contact the healthcare provider.

Correct answer: A

Rationale: The correct action for the nurse to take when the urine bag has not filled for 2 hours is to check if the tubing is kinked. Kinks in the tubing can obstruct the flow of urine from the catheter, leading to decreased drainage. Increasing the IV fluid rate is not the appropriate initial action in this situation as the primary concern is with the catheter drainage. Checking the catheter insertion site would be secondary to ensuring proper drainage. Contacting the healthcare provider is not necessary as the issue can often be resolved by checking for simple tubing obstructions first.

4. A client is in the radiology department at 0900 when the prescription 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 LPN/LVN 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 morning.
• 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: The correct intervention is to give the missed dose at 1300 and adjust the schedule to administer daily at 1300. This approach ensures that the client receives the correct total daily dose of levofloxacin. Choice A is incorrect because contacting the healthcare provider and completing a medication variance form would not address the immediate need to administer the missed dose. Choice B is incorrect as administering the missed dose at 1300 and resuming the 0900 schedule the next morning would result in a missed dose for that day. Choice C is not the best course of action as notifying the charge nurse and completing an incident report should come after addressing the immediate need to administer the missed dose and adjusting the schedule for future doses.

5. A client who is postoperative is being taught how to use a flow-oriented incentive spirometer. Which of the following instructions should be included by the nurse?

• A. Cough deeply after each use.
• B. Take a deep breath and hold for 10 seconds.
• C. Breathe in slowly and deeply to raise the ball or piston.
• D. Exhale forcefully before using the spirometer.

Correct answer: C

Rationale: The correct technique for using a flow-oriented incentive spirometer involves breathing in slowly and deeply to raise the ball or piston. This action helps to expand the lungs and improve lung function. Option A is incorrect as coughing deeply after each use is not part of using the spirometer. Option B is incorrect as holding the breath for 10 seconds is not the correct instruction for using the spirometer. Option D is incorrect as exhaling forcefully before using the spirometer is not the appropriate step in using this device.
