Which of the following interventions should the nurse prioritize for a client with dementia who is at risk of falls?

Correct Answer: B

Rationale: The correct answer is B. Using a bed exit alarm system is a non-restrictive intervention that alerts staff when the client tries to leave the bed, promoting safety and preventing falls. Choice A is incorrect because using restraints can have adverse effects and should be avoided whenever possible. Choice C is not the priority for a client at risk of falls due to dementia as it may increase the risk of falls without proper supervision. Choice D is also not recommended as raising all four side rails can lead to restraint and should be used cautiously, if at all. Therefore, the best option is to use a bed exit alarm system to ensure the client's safety while allowing some freedom of movement.

Correct Answer: B

Rationale: Myxedema is characterized by a decreased metabolic rate, leading to manifestations such as decreased temperature. Therefore, the correct assessment finding expected with myxedema is a decreased temperature. Choices A, C, and D are incorrect because myxedema typically presents with a decreased pulse rate, not an increased pulse rate, absence of fine tremors (which are more common in hyperthyroidism), and weight gain rather than weight loss.

Correct Answer: C

Rationale: The most important nursing action when administering IV potassium is to administer it slowly and dilute it in IV fluids. This approach helps prevent irritation and hyperkalemia. Monitoring for decreased urine output (Choice A) is important but not as critical as ensuring the safe administration of IV potassium. Administering potassium via IV push (Choice B) is unsafe and can lead to adverse effects. Ensuring the client drinks water before administration (Choice D) is not directly related to the safe administration of IV potassium.

Correct Answer: B

Rationale: The correct first action when irrigating a wound is to cleanse the wound from the center outward. This method helps remove debris and pathogens effectively, reducing the risk of infection. Choice A is incorrect because wearing sterile gloves should be done before starting the wound irrigation but is not the first action in the process. Choice C is incorrect as applying a warm compress is not the initial step in wound irrigation. Choice D is also incorrect as using a syringe to irrigate the wound comes after cleansing the wound.

Correct Answer: A

Rationale: The correct answer is to ensure the blood is compatible with the recipient's blood type. This is crucial to prevent transfusion reactions, which can be life-threatening. Choice B is incorrect because warming blood to body temperature is not a standard practice and may lead to hemolysis. Choice C is incorrect as blood products are carefully screened for clots before distribution. Choice D is incorrect because it is not necessary for the recipient to eat before a blood transfusion.
