ATI PN Comprehensive Predictor
1. A nurse is caring for a client who is postoperative following hip replacement surgery. Which of the following actions should the nurse take to prevent dislocation of the prosthesis?
- A. Cross the client's legs at the knees
- B. Maintain the client's legs in a neutral position
- C. Avoid placing a pillow under the client's knees
- D. Elevate the client's legs
Correct answer: C
Rationale: The correct action to prevent dislocation of the prosthesis after hip replacement surgery is to avoid placing a pillow under the client's knees. Placing a pillow can cause hip adduction, leading to dislocation. Crossing the client's legs at the knees and elevating the client's legs can also increase the risk of hip dislocation. Maintaining the client's legs in a neutral position is important to prevent complications.
2. What are the primary causes of respiratory acidosis?
- A. Hypoventilation and lung disease
- B. Hyperventilation and pneumonia
- C. Increased oxygen saturation and tachypnea
- D. Dehydration and hypoxia
Correct answer: A
Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.
3. What is the priority nursing action for a dehydrated client who needs fluids?
- A. Administer antiemetics to prevent vomiting
- B. Monitor electrolyte levels frequently
- C. Administer oral rehydration solutions
- D. Insert an NG tube for fluid administration
Correct answer: B
Rationale: The correct answer is to monitor electrolyte levels frequently. When a client is dehydrated and needs fluids, it is essential to monitor electrolyte levels to prevent complications such as electrolyte imbalances. Administering antiemetics to prevent vomiting (Choice A) may be necessary but is not the priority when addressing dehydration. Administering oral rehydration solutions (Choice C) can be beneficial, but monitoring electrolyte levels takes precedence to ensure proper hydration. Inserting an NG tube for fluid administration (Choice D) is invasive and not typically the first-line approach for managing dehydration.
4. A client diagnosed with dementia wanders the halls of the locked nursing unit during the day. To ensure the client's safety while walking in the halls, the nurse should do which of the following?
- A. Administer PRN haloperidol (Haldol) to decrease the need to walk
- B. Assess the client's gait for steadiness
- C. Restrain the client in a geriatric chair
- D. Administer PRN lorazepam (Ativan) to provide sedation
Correct answer: B
Rationale: Assessing the client's gait for steadiness is the most appropriate action to ensure the safety of a client with dementia while walking. This allows the nurse to identify any issues that may increase the risk of falls or accidents. Administering PRN haloperidol or lorazepam is not indicated as the first-line approach in managing wandering behavior and can have adverse effects like increased risk of falls, confusion, or oversedation. Restraint use should be avoided whenever possible, as it can lead to physical and psychological harm to the client.
5. What are the nursing interventions for a patient with hypokalemia?
- A. Administer potassium supplements and monitor ECG
- B. Provide a high-sodium diet and monitor for hypertension
- C. Monitor for muscle weakness and provide dietary education
- D. Administer diuretics and provide oral fluids
Correct answer: A
Rationale: The correct intervention for a patient with hypokalemia is to administer potassium supplements and monitor the ECG. Potassium supplements help correct the low potassium levels in the body, while ECG monitoring is essential to detect any cardiac arrhythmias associated with hypokalemia. Choice B is incorrect because a high-sodium diet would worsen hypokalemia by further depleting potassium levels. Choice C is incorrect as it only focuses on monitoring symptoms and providing dietary education, but does not address the immediate need to correct potassium levels. Choice D is also incorrect as administering diuretics would exacerbate hypokalemia by increasing potassium loss.
