An nurse is caring for a client who is postoperative following an open reduction internal fixation (ORIF) of a femur fracture. What is included in the evaluation of the neurovascular status of the client's affected extremity? (Select all that apply.)

Choice A reason: Obtaining a PAPR mask is not a step in preparing a sterile field. A PAPR mask is a powered airpurifying respirator that protects the wearer from airborne contaminants. It is not required for setting up a sterile field, unless the client has a highly infectious disease.

Choice B reason: Do not turn away from the sterile field is a step in preparing a sterile field. Turning away from the sterile field can contaminate the field or the items on it. The nurse should always face the sterile field and keep it in view.

Choice C reason: Add items to the sterile field by dropping them gently is a step in preparing a sterile field. Dropping items gently onto the sterile field prevents splashing or touching the field or the items. The nurse should open the sterile packages away from the field and drop the items close to the edge of the field.

Choice D reason: Covering the sterile field once it is set up is not a step in preparing a sterile field. Covering the sterile field can compromise its sterility and create moisture that can harbor microorganisms. The nurse should not cover the sterile field unless it is necessary to move it or store it for later use.

Choice E reason: Preparing the client before setting up the sterile field is a step in preparing a sterile field. Preparing the client involves explaining the procedure, obtaining consent, providing privacy, and positioning the client. The nurse should prepare the client before setting up the sterile field to avoid leaving the field unattended or exposing it to the client's body fluids.

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.
