Correct Answer: B

Rationale: The correct answer is B. The recent administration of opioid analgesics increases the risk for falls due to potential side effects such as sedation and dizziness. Choice A, a recent serum hemoglobin level of 16 g/dL, is not directly related to the risk for falls. Choice C, stooped posture with an unsteady gait, may indicate an existing risk but does not directly reflect the need to include 'Risk for falls' in the care plan. Choice D, expressed feelings of depression, is important to address but is not directly associated with the risk for falls.

Correct Answer: A

Rationale: Bruises on the arms in various stages of healing should be identified as a potential indication of abuse in an older adult. These bruises may suggest physical harm or neglect, which are concerning signs of abuse. Recent weight gain (Choice B) is not typically associated with abuse and can have various causes, such as dietary changes or health conditions. Complaints of joint pain (Choice C) are more likely related to musculoskeletal issues rather than abuse. Frequent visits to different providers (Choice D) could indicate seeking multiple opinions or healthcare needs and do not necessarily point to abuse.

Correct Answer: B

Rationale: To calculate the correct rate of infusion, divide the total volume by the total time: 250 ml / 4 hours = 62.5 ml/hour, which is rounded up to 63 ml/hour. This rate ensures the proper administration of the KCl over the 4-hour period. Choice A (13 ml/hour) is incorrect as it does not match the calculated rate. Choices C (80 ml/hour) and D (125 ml/hour) are also incorrect as they do not correspond to the calculated rate needed for the specified time frame.

Correct Answer: A

Rationale: The correct action when inserting an NG tube is to help the client take sips of water. This helps facilitate the insertion of the tube by promoting swallowing and passage through the esophagus. Asking the client to swallow assists in guiding the tube into the stomach. Inserting the tube without asking the client to swallow may lead to incorrect placement or discomfort. Advancing the tube continuously without pausing can cause the tube to coil in the esophagus, leading to complications. Using a large-bore tube for insertion is unnecessary and may increase the risk of injury or discomfort for the client.

Correct Answer: C

Rationale: Providing the client with washcloths to fold is a non-restrictive intervention that can help distract and engage the client, potentially reducing the need for restraints. This action promotes a therapeutic and calming environment for the confused client. Placing the client in a room away from the nurses' station (Choice A) may not address the underlying issue of confusion and agitation. Limiting the client's visitors (Choice B) may not directly assist in managing the client's behavior. Closing the door of the client's room (Choice D) does not actively engage the client in a therapeutic intervention to address the behavior.
