Correct Answer: B

Rationale: Using a bed exit alarm is the best intervention to prevent injury in a client with dementia at risk of falling. This device alerts staff when the client attempts to leave the bed, allowing for timely assistance and reducing the risk of falls. Placing the client in a room close to the nurses' station may help with supervision but does not provide immediate alerts like a bed exit alarm. Encouraging family members to stay with the client at all times may not be feasible, and raising all four side rails can lead to restraint issues and is not recommended unless necessary for the client's safety.

Correct Answer: A

Rationale: The correct answer is A: Administer antiemetic medication before meals. When a client receiving chemotherapy reports nausea and vomiting, administering antiemetic medication before meals is a priority intervention to help reduce nausea associated with chemotherapy. This proactive approach can prevent or minimize the symptoms, improving the client's quality of life during treatment. Choice B is incorrect because while encouraging the client to eat small, frequent meals can be helpful, administering antiemetic medication is the priority to address the immediate symptoms. Choice C is incorrect as avoiding eating during treatment may lead to nutritional deficits, and choice D is incorrect because providing cold beverages during meals may not effectively address the nausea and vomiting symptoms.

Correct Answer: C

Rationale: The correct instruction is to apply the prosthesis immediately upon waking each day. This helps the client adjust to and maintain mobility. Choice A is incorrect because wearing the prosthesis for only 2 hours at a time may not be sufficient for proper adjustment. Choice B is incorrect as removing the prosthesis every other day is not a standard practice and may hinder the client's mobility. Choice D is incorrect because elevating the stump for 24 hours after applying the prosthesis is unnecessary and not a recommended practice.

Correct Answer: C

Rationale: The correct answer is to monitor the client's fluid and electrolyte levels. When caring for a client with dehydration, it is crucial to assess and monitor their fluid and electrolyte status to guide appropriate interventions. Administering antiemetics may help with nausea but does not address the underlying issue of dehydration. Encouraging the client to drink oral rehydration solutions is beneficial but may not be the immediate priority if the client is severely dehydrated. Administering intravenous fluids may be necessary based on the assessment of fluid and electrolyte levels, making monitoring these levels the priority intervention.

Correct Answer: A

Rationale: The correct answer is A: Immobility and oral contraceptive use. Immobility and oral contraceptive use are significant risk factors for deep vein thrombosis (DVT). Immobility leads to blood stasis, increasing the risk of clot formation, while oral contraceptive use can promote hypercoagulability. Prevention strategies for DVT include promoting mobility to enhance blood circulation and using anticoagulants to prevent clot formation. Choices B, C, and D are incorrect. While pregnancy and smoking can increase the risk of DVT, they are not the specific factors mentioned in the question. Similarly, obesity and varicose veins, as well as hypertension and high cholesterol, are not the primary risk factors associated with DVT.
