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?

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.

Correct Answer: B

Rationale: The correct intervention for a client with COPD is to encourage pursed-lip breathing. Pursed-lip breathing helps maintain airway patency by preventing the collapse of small airways during exhalation, improving breathing efficiency. Administering oxygen at 2 L/min via nasal cannula may be appropriate for some COPD patients but is not the priority intervention. Positioning the client in high Fowler's position may help improve breathing but is not as specific as pursed-lip breathing for COPD. Encouraging deep breathing and coughing may be beneficial in other respiratory conditions, but it is not the most effective intervention for COPD.

Correct Answer: A

Rationale: When educating a patient with hypertension about lifestyle modifications, reducing sodium intake is crucial as excess sodium can contribute to high blood pressure. While increasing physical activity is beneficial for overall health, it is not the primary lifestyle modification specifically targeted at hypertension. Quitting smoking and avoiding alcohol are important for general health but are not the first-line lifestyle modifications recommended for hypertension. Therefore, the correct answer is to reduce sodium intake.

Correct Answer: D

Rationale: All of the above options are essential in preventing deep vein thrombosis (DVT) in post-operative patients. Encouraging early ambulation helps prevent blood stasis in the lower extremities, reducing the risk of DVT. Administering anticoagulants can prevent blood clots from forming. Compression stockings promote blood flow, reducing the likelihood of clot formation. Each intervention plays a crucial role in DVT prevention, making the correct answer 'All of the above.' Choices A, B, and C are not exclusive of each other but rather work synergistically to provide comprehensive prevention against DVT.

Correct Answer: A

Rationale: The correct answer is to administer a bronchodilator. During an acute asthma attack, the priority is to open the airways and improve breathing. Bronchodilators are the first-line treatment for asthma attacks as they help dilate the bronchioles, allowing for better airflow. Monitoring oxygen saturation is important but not the priority when the patient is in distress. Placing the patient in a high Fowler's position can help with breathing but is not the initial priority. Calling for assistance can be done after initiating the appropriate treatment.
