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.

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: B

Rationale: Irritability is an early sign that suctioning is necessary to clear the airway in a client with a tracheostomy. When secretions build up in the tracheostomy tube, the client may become irritable due to the discomfort and the compromised airway. Bradycardia, confusion, and hypotension are not typically early signs that suctioning is required. Bradycardia may occur if the airway becomes severely compromised, confusion may be a late sign of hypoxia, and hypotension is not directly related to the need for suctioning in a client with a tracheostomy.

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: A

Rationale: The correct answer is to maintain a patent airway and monitor for infection. These are crucial nursing interventions for patients with tracheostomies to ensure adequate oxygenation and prevent complications. Suctioning airway secretions and providing humidified oxygen can be part of the care plan but are not as essential as maintaining a patent airway. Educating the patient on self-care and tracheostomy cleaning is important for long-term management but is not as immediate as ensuring a patent airway and monitoring for infection. Changing tracheostomy ties daily is a specific task related to tracheostomy care but is not as critical as ensuring the airway is clear and infection-free.
