A nurse is caring for a client who has dementia. Which of the following interventions should the nurse take to minimize the risk for injury for this client?

Correct Answer: A

Rationale: The correct answer is A: Using a bed exit alarm system. A bed exit alarm alerts staff when a client with dementia attempts to leave the bed, reducing the risk of falls. Choice B is incorrect because raising all four side rails can lead to restraint-related injuries and is not recommended. Choice C is incorrect as applying wrist restraints should be avoided due to the risk of injury and decreased mobility. Choice D is incorrect as dimming the lights in the client's room does not directly address the risk of injury associated with dementia.

Correct Answer: C

Rationale: The correct instruction for a client with left-leg weakness using a cane is to maintain two points of support on the floor at all times. This technique provides stability and support while walking. Choice A is incorrect because the cane should be used on the stronger side to support the weaker leg. Choice B is incorrect as advancing the cane and the strong leg together may not provide adequate support and balance. Choice D is incorrect as the distance to advance the cane with each step can vary depending on the individual's needs and abilities.

Correct Answer: B

Rationale: The correct answer is to irrigate the NG tube with sterile water. When a client with an NG tube attached to low suctioning becomes nauseated and there is a decrease in the flow of gastric secretions, it indicates a possible blockage in the tube. Irrigating the tube with sterile water can help clear the blockage, allowing for proper suctioning and relieving the client's nausea. Increasing the suction pressure (Choice A) can further worsen the issue by potentially causing harm to the client. Turning the client on their side (Choice C) may not address the underlying problem of tube blockage. Replacing the NG tube with a new one (Choice D) should only be considered if other interventions, like irrigation, fail to clear the blockage.

Correct Answer: A

Rationale: The correct teaching point for a client with left-leg weakness learning to use a cane is to maintain two points of support on the ground at all times. This ensures stability and helps prevent falls. Choice B, using the cane on the weak side of the body, may lead to imbalance and decreased support. Choice C, advancing the cane a specific distance with each step, is not as crucial as maintaining two points of support. Choice D, advancing the cane and the strong leg simultaneously, may also compromise stability and support for the weak leg.

Correct Answer: D

Rationale: The correct answer is to replace the NG tube with a new one. When a client with an NG tube experiences nausea and decreased gastric secretions, it indicates a possible problem with the tube itself. Replacing the tube ensures proper functioning and can alleviate the symptoms. Increasing the suction pressure (Choice A) can worsen the client's condition. Turning the client onto their side (Choice B) may be helpful in some situations but does not address the underlying issue. Irrigating the NG tube with sterile water (Choice C) is not the priority and may not resolve the problem.
