Correct Answer: D

Rationale: All of these interventions are crucial in reducing the risk of falls in elderly patients. Encouraging the use of assistive devices helps provide support and stability, clearing walkways minimizes tripping hazards, and ensuring proper lighting enhances visibility and reduces the chances of falls. Therefore, choosing 'All of the above' is the most appropriate answer as each intervention plays a significant role in fall prevention.

Correct Answer: D

Rationale: The correct answer is D. Absent bowel sounds are concerning as they indicate potential complications such as ileus, which is a risk after abdominal surgery. The absence of bowel sounds can suggest decreased or absent intestinal motility, which may lead to complications if not addressed promptly. The nurse should notify the provider immediately to assess the situation and intervene accordingly. Choices A and B are common postoperative occurrences and do not necessarily warrant immediate provider notification. Choice C, vomiting, while concerning, may be a common postoperative symptom; however, absent bowel sounds are a more critical finding that requires prompt attention.

Correct Answer: B

Rationale: Irritability is indeed an early sign that a tracheostomy client may require suctioning. When a tracheostomy client becomes irritable, it can indicate that there is a need for suctioning to clear the airway. Bradycardia (choice A) refers to a slow heart rate and is not typically a direct indication for suctioning. Hypotension (choice C) indicates low blood pressure and is not specifically related to the need for suctioning. Decreased respiratory rate (choice D) can be a sign of respiratory distress, but irritability is a more direct and early indication of the need for suctioning in a tracheostomy client.

Correct Answer: B

Rationale: The correct intervention for a client with dementia at risk of falls is to use a bed exit alarm to notify staff when the client tries to leave the bed. This intervention helps prevent falls while still allowing some freedom of movement. Choice A is incorrect because using restraints can lead to complications and is considered a form of restraint which should be avoided. Choice C is not suitable for a client at high risk of falls due to dementia as it may increase the risk of falls. Choice D is not recommended as raising all four side rails can be considered a form of physical restraint and may not be the best approach to prevent falls in a client with dementia.

Correct Answer: D

Rationale: The LPN should question the assignment of replacing the PCA pump cartridge and tubing as it is outside the LPN's scope of practice. LPNs are not trained to handle tasks related to PCA pumps, which involve medication administration and monitoring that are typically within the RN's responsibilities. Assisting a postop client with an incentive spirometer (Choice A), collecting a clean catch urine specimen (Choice B), and providing nasopharyngeal suctioning for a client with pneumonia (Choice C) are all tasks that fall within the LPN's scope of practice and do not require questioning by the LPN.
