The physician orders risperidone (Risperdal) for a client with Alzheimer's disease. The nurse anticipates administering this medication to help decrease which of the following behaviors?

Correct Answer: C

Rationale: The correct answer is C: Agitation and assaultiveness. Risperidone is commonly prescribed for clients with Alzheimer's disease to reduce symptoms of agitation and aggressive behavior. This medication helps in managing challenging behaviors often seen in individuals with Alzheimer's. Choice A, sleep disturbances, is incorrect as risperidone is not primarily indicated for treating sleep issues in Alzheimer's patients. Choice B, concomitant depression, is also incorrect as risperidone is not the first-line treatment for depression in Alzheimer's disease. Choice D, confusion and withdrawal, is incorrect as risperidone does not directly target these symptoms in Alzheimer's patients.

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: Upon noticing phlebitis at the IV site, the nurse should remove the IV catheter and restart it in another location. Phlebitis is inflammation of the vein, and leaving the IV catheter in place can lead to further complications such as infection. Applying a cold compress (Choice A) may provide temporary relief but does not address the underlying issue. Notifying the provider immediately (Choice B) is important, but the immediate action to prevent complications is to remove the IV catheter. Monitoring the site for signs of infection (Choice D) is necessary, but the priority action is to remove and reinsert the IV catheter to prevent worsening of the phlebitis.

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.
