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 group of clients about the risk factors for osteoporosis. Which of the following should the nurse include as a risk factor for osteoporosis?

A. Early menopause
B. History of falls
C. African American race
D. Obesity

Correct answer: A

Rationale: The correct answer is A: Early menopause. A client who goes into early menopause, from natural or surgical causes, is at a greater risk for developing osteoporosis due to the rapid drop in estrogen levels. Choice B, history of falls, is not a direct risk factor for osteoporosis but rather a risk for fractures related to osteoporosis. Choice C, African American race, is actually associated with a lower risk of osteoporosis. Choice D, obesity, is considered a protective factor against osteoporosis as excess weight can provide additional support to bones.

3. What signs indicate increased intracranial pressure (IICP)?

A. Restlessness, irritability, and confusion
B. Sudden onset of seizures
C. Bradycardia and altered pupil response
D. Loss of consciousness

Correct answer: A

Rationale: Restlessness, irritability, and confusion are early signs of increased intracranial pressure (IICP). These symptoms occur due to the brain's increased pressure within the skull. Sudden onset of seizures (Choice B) is not typically associated with increased intracranial pressure. Bradycardia and altered pupil response (Choice C) are signs of advanced or worsening IICP. Loss of consciousness (Choice D) is a late sign of increased intracranial pressure.

4. A nurse is caring for a client who has increased intracranial pressure (ICP). Which of the following interventions should the nurse implement?

A. Place several pillows behind the client's head
B. Place the client in a Sim's position
C. Keep the client's neck in a midline position
D. Maintain flexion of the client's hips at a 90° angle

Correct answer: C

Rationale: Keeping the client's neck in a midline position is crucial for managing increased intracranial pressure. This position helps optimize blood flow and minimizes the risk of further increasing ICP. Placing several pillows behind the client's head (Choice A) may inadvertently elevate the head, potentially worsening ICP. Placing the client in a Sim's position (Choice B) or maintaining flexion of the client's hips at a 90° angle (Choice D) are not directly related to managing increased ICP.

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

A. Unrelieved pain, pallor, and pulselessness
B. Localized swelling and numbness
C. Fever and infection
D. Weakness and fatigue

Correct answer: A

Rationale: In a patient with compartment syndrome, the key symptoms include unrelieved pain, pallor, and pulselessness. These symptoms indicate reduced circulation in the affected compartment. Choice B is incorrect as localized swelling and numbness are not typically associated with compartment syndrome. Choice C is incorrect as fever and infection are not primary symptoms of compartment syndrome. Choice D is incorrect as weakness and fatigue are not typically seen in compartment syndrome.
