Correct Answer is A
Explanation
Choice A rationale
Informing the client that the nurse is busy and will talk to him later is a professional and appropriate response. This approach acknowledges the client's need for attention while setting a clear boundary that respects the nurse's current responsibilities. It also provides a time frame for when the client can expect to receive attention, which can help reduce anxiety or agitation. This method promotes orderly and efficient care without compromising the needs of the newly admitted client.
Choice B rationale
Putting the client's behavior on extinction by not acknowledging it might seem effective, but it can lead to feelings of being ignored or dismissed. This approach is not therapeutic in a psychiatric setting, where clients often require validation and structured interactions. Ignoring a client's request can escalate the behavior or contribute to a sense of isolation. Therapeutic communication involves active listening and responding appropriately to all clients.
Choice C rationale
Introducing the client to the newly admitted client and asking him to join the conversation can be disruptive and inappropriate. This action may not address the urgency of the client's concern and can intrude on the privacy and focus needed for the newly admitted client. It is important to maintain a structured and private environment for admissions to ensure that the new client feels supported and understood.
Choice D rationale
Encouraging the client to go to the nurse's station and talk with another nurse may not be practical, especially if the other nurses are also occupied. This response can seem dismissive and may not adequately address the client's immediate concern. It is more effective to provide a clear time frame or alternative solution for when the client will receive attention. Proper delegation requires ensuring that the alternative option is available and can provide the necessary support.
Correct Answer is B
Explanation
Choice A rationale
Mixed berries are rich in antioxidants and nutrients, but they do not specifically provide the calcium and vitamin D necessary to support bone health in postmenopausal women, who are at increased risk for osteoporosis.
Choice B rationale
Low-fat yogurt is a good source of calcium and vitamin D, which are vital for maintaining bone density and preventing osteoporosis in postmenopausal women. These nutrients are crucial as estrogen levels drop, increasing the risk of bone loss.
Choice C rationale
Carrots are high in beta-carotene and fiber but do not significantly contribute to calcium and vitamin D intake. While beneficial for overall health, they are not the primary focus for bone health in postmenopausal women.
Choice D rationale
Beets offer various vitamins and minerals but lack substantial amounts of calcium and vitamin D. They are not emphasized for bone health in postmenopausal women, who need to prioritize nutrients that support bone density.
