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.

What is the primary nursing action for a patient experiencing continuous bubbling in the chest tube water seal chamber?
- A. Tighten the connections of the chest tube system
- B. Clamp the chest tube
- C. Continue monitoring the chest tube
- D. Replace the chest tube system
Correct Answer: A
Rationale: The correct answer is to tighten the connections of the chest tube system. Continuous bubbling in the chest tube water seal chamber indicates an air leak. By tightening the connections of the chest tube system, the nurse can often resolve the issue by ensuring there are no loose connections allowing air to enter. Clamping the chest tube or replacing the chest tube system are not appropriate actions in this situation. Clamping the tube can cause a dangerous buildup of pressure, while replacing the system should only be considered if tightening the connections does not resolve the air leak.
What is the priority intervention for a patient with unstable angina?
- A. Administer nitroglycerin
- B. Establish IV access
- C. Auscultate heart sounds
- D. Administer aspirin
Correct Answer: A
Rationale: The correct answer is to administer nitroglycerin. Nitroglycerin is the priority intervention for a patient with unstable angina as it helps dilate blood vessels, improve blood flow to the heart, relieve chest pain, and prevent further cardiac damage. Establishing IV access (choice B) may be important but is not the priority over administering nitroglycerin in this scenario. Auscultating heart sounds (choice C) and administering aspirin (choice D) are also important aspects of managing unstable angina, but they are not the immediate priority intervention when a patient is experiencing chest pain.
What should the nurse do if a patient experiences abdominal cramping during enema administration?
- A. Lower the height of the solution container
- B. Increase the flow of the enema solution
- C. Stop the procedure and remove the tubing
- D. Continue the enema at a slower rate
Correct Answer: A
Rationale: When a patient experiences abdominal cramping during enema administration, the nurse should lower the height of the solution container. This adjustment can help alleviate the cramping by reducing the speed and pressure of the solution entering the colon. Increasing the flow of the enema solution (Choice B) can exacerbate the cramping. Stopping the procedure and removing the tubing (Choice C) may be necessary in extreme cases but is not the initial step. Continuing the enema at a slower rate (Choice D) may not effectively address the cramping, making it less optimal than lowering the height of the solution container.
What ECG changes are expected in a patient with hypokalemia?
- A. Flattened T waves
- B. Prominent U waves
- C. Widened QRS complexes
- D. Tall T waves
Correct Answer: A
Rationale: Flattened T waves are an early indicator of hypokalemia on an ECG. Hypokalemia primarily presents with flattened T waves, not prominent U waves, widened QRS complexes, or tall T waves. Prominent U waves are associated with hypokalemia only in severe cases. Widened QRS complexes are more indicative of hyperkalemia, while tall T waves are seen in hyperkalemia as well.
A client has a Transient Ischemic Attack (TIA). What should the nurse teach?
- A. Avoid eating within 3 hours of bedtime
- B. Consume liquids between meals
- C. Eat large meals to increase caloric intake
- D. Avoid liquids to prevent aspiration
Correct Answer: A
Rationale: The correct answer is A: Avoid eating within 3 hours of bedtime. For a client with a Transient Ischemic Attack (TIA), it is crucial to avoid eating within 3 hours of bedtime to reduce reflux that can worsen symptoms. Choice B is incorrect because consuming liquids between meals is not specifically related to managing TIA. Choice C is incorrect as eating large meals may not be recommended, especially if the client needs to watch their caloric intake. Choice D is incorrect because avoiding liquids entirely can lead to dehydration and is not a standard recommendation for TIA management.
