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. A nurse is teaching a client about using a continuous positive airway pressure (CPAP) device to treat obstructive sleep apnea. Which of the following information should the nurse include in the teaching?

• A. It delivers a preset amount of inspiratory pressure throughout the breathing cycle
• B. It has a continuous adjustment feature that changes the airway pressure throughout the cycle
• C. It delivers a preset amount of airway pressure throughout the breathing cycle
• D. It delivers positive pressure at the end of each breath

Correct answer: C

Rationale: The correct answer is C because a CPAP device delivers a preset amount of positive airway pressure continuously throughout all inspiration and expiration cycles. Choice A is incorrect because CPAP does not deliver inspiratory pressure at the beginning of each breath; it provides continuous positive pressure. Choice B is incorrect because CPAP typically delivers a constant pressure rather than having a feature that changes pressure throughout the cycle. Choice D is incorrect as CPAP does not deliver positive pressure specifically at the end of each breath; it maintains a consistent pressure throughout the breathing cycle.

3. What are the expected signs of compartment syndrome?

• A. Unrelieved pain, pallor, and pulselessness
• B. Fever, swelling, and redness
• C. Muscle cramps and weakness
• D. Redness and itching

Correct answer: A

Rationale: The correct answer is A: Unrelieved pain, pallor, and pulselessness. Compartment syndrome is characterized by increased pressure within a muscle compartment, leading to inadequate blood supply. This results in severe pain that is unrelieved by rest or medication, pallor due to compromised blood flow, and pulselessness as a late sign of severe ischemia. Choices B, C, and D are incorrect. Fever, swelling, and redness are not typical signs of compartment syndrome. Muscle cramps and weakness may occur due to other conditions, but they are not primary indicators of compartment syndrome. Redness and itching are also not commonly associated with compartment syndrome.

4. 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.

5. A patient reports abdominal cramping during an enema administration. What action should the nurse take?

• A. Increase the flow of the enema
• B. Lower the height of the enema solution container
• C. Stop the enema procedure
• D. Remove the enema tubing

Correct answer: B

Rationale: When a patient experiences abdominal cramping during an enema administration, the nurse should lower the height of the enema solution container. Lowering the container helps to relieve cramping by slowing the flow of the solution, making it more comfortable for the patient. Increasing the flow (Choice A) would exacerbate the cramping. Stopping the procedure (Choice C) may not be necessary if adjusting the height resolves the issue. Removing the enema tubing (Choice D) is not the initial action indicated for cramping; adjusting the height is the more appropriate intervention.
