1. 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.

2. What ECG changes are seen with hyperkalemia?

A. Flattened T waves
B. Elevated ST segments
C. Prominent U waves
D. Widened QRS complex

Correct answer: A

Rationale: Flattened T waves are an early ECG sign of hyperkalemia. Hyperkalemia affects the repolarization phase of the cardiac action potential, leading to changes such as peaked T waves, prolonged PR interval, widened QRS complex, and ultimately sine wave pattern. Elevated ST segments, prominent U waves, and widened QRS complex are not typically associated with hyperkalemia, making choices B, C, and D incorrect.

3. What medication should be given first to a patient experiencing wheezing and coughing due to an allergic reaction?

A. Albuterol 3 ml via nebulizer
B. Cromolyn via nebulizer
C. Aminophylline IV
D. Methylprednisolone 100 mg IV

Correct answer: A

Rationale: The correct answer is Albuterol 3 ml via nebulizer. Albuterol is a bronchodilator that helps relieve wheezing and coughing by opening up the airways, making it the first-line treatment for allergic reactions presenting with these symptoms. Cromolyn and aminophylline are not typically used as first-line treatments for acute allergic reactions with wheezing and coughing. Methylprednisolone, a corticosteroid, may be beneficial for inflammation in the setting of an allergic reaction but is not the initial medication of choice to address wheezing and coughing.

4. What is the preferred electrical intervention for a patient with ventricular tachycardia with a pulse?

A. Synchronized cardioversion
B. Defibrillation
C. Pacing
D. Medication administration

Correct answer: A

Rationale: The correct answer is A: Synchronized cardioversion. In ventricular tachycardia with a pulse, synchronized cardioversion is the preferred electrical intervention. Synchronized cardioversion is used to treat tachyarrhythmias where there is a pulse present. Defibrillation (choice B) is used in emergencies for pulseless ventricular tachycardia or ventricular fibrillation. Pacing (choice C) is more suitable for bradycardias or certain conduction abnormalities. Medication administration (choice D) may be used in stable cases or as an adjunct to other treatments, but synchronized cardioversion is the primary intervention for ventricular tachycardia with a pulse.

5. When caring for a patient with hypokalemia, what should the nurse monitor for?

A. Monitor for muscle weakness
B. Check for cardiac dysrhythmias
C. Monitor for bradycardia
D. Monitor for seizures

Correct answer: A

Rationale: Corrected Answer: Muscle weakness is a common sign of hypokalemia. The nurse should monitor for muscle weakness as potassium plays a crucial role in muscle function. Choices B, C, and D are incorrect because although hypokalemia can lead to cardiac dysrhythmias, bradycardia, and even seizures in severe cases, muscle weakness is a more common and specific sign directly related to potassium levels.
