What are the causes of a pressure ulcer? (Select all that apply.)
Ischemia
Immobility
Poor nutrition
Moisture
Adequate perfusion
Correct Answer : A,B,C,D
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.

Correct Answer is D
Explanation
Choice A reason: Allowing the client to sleep to build up stamina is not the priority intervention, because it does not address the psychosocial needs of the client. Sleeping is a physiological need, not a psychosocial need. Sleeping may help the client recover physically, but it does not help the client cope emotionally or socially with the isolation.
Choice B reason: Maintaining a sixfoot distance from the client is not the priority intervention, because it does not enhance the psychosocial needs of the client. Maintaining a sixfoot distance from the client is a safety measure, not a psychosocial intervention. Maintaining a sixfoot distance from the client may help prevent the transmission of infection, but it does not help the client feel less lonely or isolated.
Choice C reason: Providing a timeframe for the isolation is not the priority intervention, because it does not enhance the psychosocial needs of the client. Providing a timeframe for the isolation is an informational intervention, not a psychosocial intervention. Providing a timeframe for the isolation may help the client understand the rationale and duration of the precautions, but it does not help the client feel more engaged or supported.
Choice D reason: Providing the client with diversional activities is the priority intervention, because it enhances the psychosocial needs of the client. Providing the client with diversional activities is a psychosocial intervention, not a physiological, safety, or informational intervention. Providing the client with diversional activities may help the client feel more entertained, stimulated, and connected with others, which can reduce the negative effects of isolation.
Correct Answer is D
Explanation
Choice A reason: Postponing daily bed bath is not appropriate for reducing the risk of a friction and shear injury. Bed bath is a hygiene measure that helps to keep the skin clean and dry and prevent infection. Friction and shear are caused by the rubbing and pulling of the skin against the bed surface, not by the bed bath itself.
Choice B reason: Elevating the client’s head of the bed to 45 degrees is not appropriate for reducing the risk of a friction and shear injury. In fact, this may increase the risk as the client may slide down the bed due to gravity and cause more friction and shear on the skin. The head of the bed should be kept at the lowest possible angle, preferably less than 30 degrees, unless contraindicated by the client’s condition.
Choice C reason: Caregiver independently slides the client up in bed is not appropriate for reducing the risk of a friction and shear injury. This may cause more damage to the skin as the caregiver may exert excessive force and drag the client’s skin along the bed surface. The caregiver should use a draw sheet or a slide board to lift and reposition the client with the help of another person.
Choice D reason: Use a mechanical lift to reposition the client every 2 hours is the most appropriate intervention for reducing the risk of a friction and shear injury. A mechanical lift is a device that helps to transfer and reposition the client safely and comfortably. It reduces the friction and shear on the skin by lifting the client off the bed surface and avoiding any sliding or dragging. It also prevents the caregiver from injuring themselves by lifting the client manually. The client should be repositioned every 2 hours to relieve the pressure on the skin and prevent pressure ulcers.
