The nurse is preparing to administer medications to a client with osteoarthritis. What is the purpose of the medications?

Choice A reason: Ischemia is a cause of a pressure ulcer, because it means reduced blood flow to the tissues, which can lead to tissue hypoxia, necrosis, and ulceration. Ischemia can result from factors such as compression, friction, shear, or vascular disease.

Choice B reason: Immobility is a cause of a pressure ulcer, because it means prolonged pressure on the bony prominences, which can impair blood flow and cause ischemia, tissue damage, and ulceration. Immobility can result from factors such as paralysis, injury, illness, or sedation.

Choice C reason: Poor nutrition is a cause of a pressure ulcer, because it means inadequate intake or absorption of nutrients, such as protein, calories, vitamins, and minerals, which are essential for tissue repair and wound healing. Poor nutrition can result from factors such as anorexia, malabsorption, or poverty.

Choice D reason: Moisture is a cause of a pressure ulcer, because it means excessive wetness or dampness of the skin, which can weaken the skin barrier, increase the risk of infection, and delay wound healing. Moisture can result from factors such as incontinence, perspiration, or wound drainage.

Choice E reason: Adequate perfusion is not a cause of a pressure ulcer, but rather a protective factor. Adequate perfusion means sufficient blood flow to the tissues, which can prevent ischemia, tissue damage, and ulceration. Adequate perfusion can be promoted by factors such as regular repositioning, pressure relief, and exercise.

Choice A reason: Calling the chaplain for support is not the priority nursing intervention for a client who speaks only Spanish. The chaplain may not be able to communicate with the client or understand their needs. This choice does not address the language barrier or the client's reason for admission.

Choice B reason: Verifying the reason for admission is an important nursing intervention, but it is not the priority for a client who speaks only Spanish. The nurse cannot verify the reason for admission without communicating with the client or their family. This choice does not address the language barrier or the client's safety.

Choice C reason: Requesting a medical interpreter is the priority nursing intervention for a client who speaks only Spanish. The medical interpreter can facilitate communication between the nurse and the client, and help the nurse assess the client's condition, reason for admission, and needs. This choice addresses the language barrier and the client's safety.

Choice D reason: Giving the client a tour of the unit is not the priority nursing intervention for a client who speaks only Spanish. The client may not understand the tour or the information given by the nurse. This choice does not address the language barrier or the client's reason for admission.
