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: A

Rationale: The correct answer is to administer oxygen. In a patient experiencing respiratory distress, the primary concern is ensuring an adequate oxygen supply to the body. By administering oxygen, you can help improve oxygenation, which is crucial for the patient's overall well-being. Assessing airway patency is important but administering oxygen takes precedence as it directly addresses the oxygenation concern. Monitoring oxygen saturation is also essential, but the immediate action should be to provide oxygen. Calling for assistance can be important but is not the first priority when dealing with a patient in respiratory distress.

Correct Answer: C

Rationale: The correct action for the nurse to take when maintaining droplet precautions for a client with meningitis is to wear a surgical mask within 3 feet of the client. This is essential to prevent the transmission of meningitis via respiratory droplets. Choice A is incorrect because wearing a gown is not specifically required for droplet precautions. Choice B suggests maintaining a distance of 6 feet, which is more applicable to airborne precautions, not droplet precautions. Choice D is incorrect as gloves should be removed and disposed of properly, but it is not related to droplet precautions specifically.

Correct Answer: B

Rationale: Performing fundal massage is the priority action in this scenario. Fundal massage helps contract the uterus, which is essential in reducing excessive lochia postpartum. Administering oxytocin may be indicated later, but fundal massage should be the initial intervention to address the issue. Administering IV fluids may not directly address the cause of excessive lochia, and calling the provider should come after implementing immediate nursing interventions.

Correct Answer: A

Rationale: The correct answer is to administer potassium-wasting diuretics. Hyperkalemia, which is high potassium levels, is managed by promoting the excretion of potassium from the body. Potassium-wasting diuretics help the kidneys eliminate excess potassium. Encouraging a low-potassium diet (choice B) is important for long-term management but not the immediate intervention for hyperkalemia. Administering potassium supplements (choice C) would worsen the condition by further increasing potassium levels. Administering IV fluids (choice D) may help with hydration but does not directly address the high potassium levels characteristic of hyperkalemia.
