Nursing Elites

1. What are the expected changes on an ECG for a patient with hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. ST elevation
• D. Wide QRS complexes

Correct answer: A

Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. Hypokalemia primarily manifests as flattened T waves on an ECG. While prominent U waves can be seen in hypokalemia, they are not as specific as flattened T waves. ST elevation is more commonly associated with conditions like myocardial infarction rather than hypokalemia. Wide QRS complexes are typically not a feature of hypokalemia on an ECG.

2. What is the priority nursing action when a patient with chest pain presents with possible acute coronary syndrome?

• A. Administer sublingual nitroglycerin
• B. Obtain IV access
• C. Check the patient's cardiac enzymes
• D. Administer aspirin

Correct answer: A

Rationale: The priority nursing action when a patient with chest pain presents with possible acute coronary syndrome is to administer sublingual nitroglycerin. Sublingual nitroglycerin helps dilate blood vessels, reducing cardiac workload, and improving blood supply to the heart muscle, thus relieving pain and enhancing blood flow to the heart. While obtaining IV access is important for administering medications and fluids, it is not the priority over addressing pain and improving blood flow. Checking the patient's cardiac enzymes is crucial for diagnosis and ongoing management but not the immediate priority when the patient is in pain. Administering aspirin is also a vital intervention in acute coronary syndrome, but in this scenario, it is not the priority action compared to providing immediate pain relief and enhancing blood flow to the heart.

3. A nurse is developing a plan of care for a client who will be placed in halo traction following surgical repair of the cervical spine. Which of the following interventions should the nurse include in the plan?

• A. Inspect the pin site every 4 hours
• B. Monitor the client's skin under the halo vest
• C. Ensure two personnel hold the halo device when repositioning the client
• D. Apply powder to the client's skin under the vest to decrease itching

Correct answer: B

Rationale: The correct answer is to monitor the client's skin under the halo vest. This is important to assess for signs of skin issues such as excessive sweating, redness, or blistering, which can lead to skin breakdown and infection. Choice A is incorrect because while inspecting the pin site is important, it should be done more frequently than every 4 hours. Choice C is incorrect as the halo device should be supported by the client's body weight, not personnel, when repositioning. Choice D is incorrect because applying powder frequently can increase the risk of skin irritation and infection.

4. What ECG changes are expected in hypokalemia?

• A. Flattened T waves on ECG
• B. Prominent U waves on ECG
• C. Widened QRS complexes on ECG
• D. ST elevation on ECG

Correct answer: A

Rationale: In hypokalemia, flattened T waves are a common ECG finding due to the decreased extracellular potassium affecting repolarization. Prominent U waves are typically seen in hypokalemia as well, but flattened T waves are the more specific and early ECG change. Widened QRS complexes are associated with hyperkalemia, not hypokalemia. ST elevation is often seen in conditions like myocardial infarction, pericarditis, or early repolarization syndrome, not specifically in hypokalemia.

5. What symptoms are expected in a patient with compartment syndrome?

• A. Unrelieved pain, pallor, and pulselessness
• B. Localized swelling and numbness
• C. Fever and infection
• D. Weakness and fatigue

Correct answer: A

Rationale: In a patient with compartment syndrome, the key symptoms include unrelieved pain, pallor, and pulselessness. These symptoms indicate reduced circulation in the affected compartment. Choice B is incorrect as localized swelling and numbness are not typically associated with compartment syndrome. Choice C is incorrect as fever and infection are not primary symptoms of compartment syndrome. Choice D is incorrect as weakness and fatigue are not typically seen in compartment syndrome.
