1. What ECG change is associated with hyperkalemia?

• A. Flattened T waves
• B. ST depression
• C. Prominent U waves
• D. Elevated ST segments

Correct answer: B

Rationale: The correct ECG change associated with hyperkalemia is ST depression. Hyperkalemia typically presents with ECG changes such as peaked T waves, prolonged PR interval, widened QRS complex, and finally, ST segment depression. Flattened T waves are more commonly associated with hypokalemia. Prominent U waves are seen in hypokalemia as well. Elevated ST segments are not a typical ECG finding in hyperkalemia.

2. What should the healthcare provider do if a patient presents with chest pain and possible acute coronary syndrome?

• A. Administer sublingual nitroglycerin
• B. Administer aspirin
• C. Obtain cardiac enzymes
• D. Get IV access and auscultate heart sounds

Correct answer: A

Rationale: Administering sublingual nitroglycerin is the priority action in the treatment of chest pain in acute coronary syndrome. Nitroglycerin helps dilate blood vessels, improving blood flow to the heart and relieving chest pain. Aspirin can also be given to reduce clot formation, but nitroglycerin takes precedence in providing immediate relief. Obtaining cardiac enzymes and assessing heart sounds are important steps in the diagnostic process but do not address the immediate need to relieve chest pain and prevent cardiac tissue damage. Therefore, administering sublingual nitroglycerin is the most appropriate initial intervention for a patient presenting with chest pain and possible acute coronary syndrome.

3. A nurse is planning care for a client who has acute post-streptococcal glomerulonephritis. Which of the following interventions should the nurse include in the client's plan?

• A. Encourage a high-protein diet
• B. Increase the client's fluid intake
• C. Administer diuretics
• D. Weigh the client twice a week

Correct answer: C

Rationale: Administering diuretics is a crucial intervention for a client with acute post-streptococcal glomerulonephritis as it helps reduce edema by increasing urine output and managing symptoms of glomerulonephritis. Encouraging a high-protein diet (Choice A) is not recommended in this case because it can put additional stress on the kidneys. Increasing fluid intake (Choice B) may worsen edema in these clients. Weighing the client twice a week (Choice D) is important for monitoring fluid balance but is not as immediate and directly beneficial as administering diuretics.

4. What are the signs and symptoms of compartment syndrome?

• A. Unrelieved pain, pallor, and pulselessness
• B. Localized redness and swelling
• C. Fever and infection
• D. Loss of sensation in the affected area

Correct answer: A

Rationale: The signs and symptoms of compartment syndrome include unrelieved pain, pallor, and pulselessness. Unrelieved pain is a key characteristic, indicating tissue ischemia due to increased pressure within a closed anatomic space. Pallor results from compromised blood flow, and pulselessness indicates severe ischemia requiring immediate intervention. Choices B, C, and D are incorrect because localized redness and swelling, fever and infection, and loss of sensation are not specific signs of compartment syndrome. Therefore, the correct answer is A.

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

• A. Unrelieved pain, pallor, and pulselessness
• B. Fever and infection
• C. Localized redness and swelling
• D. Loss of sensation in the affected area

Correct answer: A

Rationale: In a patient with compartment syndrome, the classic signs include unrelieved pain, pallor, and pulselessness. These signs indicate compromised circulation and neurovascular function in the affected compartment. Fever and infection (Choice B) are not typical signs of compartment syndrome. Localized redness and swelling (Choice C) can be seen in other conditions like cellulitis but are not specific to compartment syndrome. Loss of sensation in the affected area (Choice D) may occur in some cases but is not as specific or consistent as unrelieved pain, pallor, and pulselessness in diagnosing compartment syndrome.
