Nursing Elites

1. What are the expected ECG changes in hypokalemia?

• A. Flattened T waves
• B. ST elevation
• C. Wide QRS complex
• D. Tall T waves

Correct answer: A

Rationale: Flattened T waves are the most common ECG change seen in patients with hypokalemia. Hypokalemia leads to a decrease in serum potassium levels, affecting the repolarization phase of the cardiac action potential. This results in T wave flattening or inversion. ST elevation is typically seen in conditions like myocardial infarction, not in hypokalemia. Wide QRS complex is more associated with hyperkalemia than hypokalemia. Tall T waves are often seen in hyperkalemia, not hypokalemia.

2. What is the preferred treatment for a patient with unstable angina admitted with chest pain?

• A. Administer sublingual nitroglycerin
• B. Establish IV access
• C. Auscultate heart sounds
• D. Obtain cardiac enzymes

Correct answer: A

Rationale: The correct answer is to administer sublingual nitroglycerin. Nitroglycerin helps vasodilate coronary arteries, improving blood flow to the heart, relieving chest pain, and preventing cardiac tissue damage. Establishing IV access (choice B) is important but not the preferred initial treatment for unstable angina with chest pain. Auscultating heart sounds (choice C) and obtaining cardiac enzymes (choice D) are relevant assessments but do not address the immediate symptomatic relief needed for a patient with unstable angina and chest pain.

3. What is the expected finding in a patient with compartment syndrome?

• A. Unrelieved pain, pallor, and pulselessness
• B. Localized swelling and redness
• C. Numbness and tingling
• D. Fever and infection

Correct answer: A

Rationale: In a patient with compartment syndrome, the expected finding includes unrelieved pain, pallor, and pulselessness. These are classic signs of compartment syndrome and indicate compromised blood flow and tissue perfusion, necessitating urgent intervention. Choices B, C, and D are incorrect because localized swelling and redness, numbness and tingling, as well as fever and infection, are not typical findings associated with compartment syndrome.

4. A nurse is reviewing the medical record of a client who has unstable angina. Which of the following findings should the nurse report to the provider?

• A. Breath sounds
• B. Temperature
• C. Blood pressure
• D. Creatine kinase

Correct answer: A

Rationale: The correct answer is A: Breath sounds. When caring for a client with unstable angina, changes in breath sounds could indicate left ventricular failure and pulmonary edema due to decreased cardiac output and reduced cardiac perfusion. Reporting any abnormalities in breath sounds promptly to the provider is crucial to prevent further complications. Choices B, C, and D are not directly related to the immediate management of unstable angina. Temperature, blood pressure, and creatine kinase levels are important parameters to monitor but are not the priority in this situation.

5. 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.
