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: Properly disposing of contaminated equipment is an important infectioncontrol measure, but it is not the most effective way to prevent the spread of pathogens during client care. Contaminated equipment, such as gloves, gowns, masks, or needles, should be disposed of in designated containers or bags to prevent exposure or injury to others. However, this measure does not eliminate the risk of transmission of pathogens from the hands of the health care worker to the client or the environment.
Choice B reason: Discarding used syringes into appropriate containers is an important infectioncontrol measure, but it is not the most effective way to prevent the spread of pathogens during client care. Used syringes, especially those that contain blood or body fluids, should be discarded into punctureresistant, leakproof, and labeled containers to prevent needlestick injuries or exposure to others. However, this measure does not eliminate the risk of transmission of pathogens from the hands of the health care worker to the client or the environment.
Choice C reason: Changing soiled linens is an important infectioncontrol measure, but it is not the most effective way to prevent the spread of pathogens during client care. Soiled linens, especially those that contain blood or body fluids, should be changed and handled with gloves and minimal agitation to prevent contamination or aerosolization of pathogens. However, this measure does not eliminate the risk of transmission of pathogens from the hands of the health care worker to the client or the environment.
Choice D reason: Performing hand hygiene is the most effective way to prevent the spread of pathogens during client care, because it reduces the number of microorganisms on the hands of the health care worker, which are the most common source and mode of transmission of infection. Hand hygiene should be performed before and after contact with the client, after contact with potentially infectious materials, after removing gloves, and before and after performing invasive procedures. Hand hygiene can be performed by washing with soap and water or using alcoholbased hand rubs.
Correct Answer is A
Explanation
Choice A reason: This is the highest priority client because sudden and increasing pain in a fractured arm can indicate a complication, such as compartment syndrome, infection, or nerve damage. Compartment syndrome is a condition where the pressure inside the muscles increases to dangerous levels, causing severe pain, reduced blood flow, and tissue death. Infection is a condition where microorganisms invade the wound site, causing inflammation, pus, and fever. Nerve damage is a condition where the nerves are injured by the fracture, causing numbness, tingling, or weakness. The nurse should see this client first and assess the arm for any signs of these complications, such as swelling, pallor, loss of sensation, or impaired movement. The nurse should also elevate the arm, loosen any bandages or casts, and administer pain medication as ordered.
Choice B reason: This is not the highest priority client because a fractured ankle is a common and stable condition that affects the lower extremity. A glass of water is a comfort and hydration need that can be met by the nurse or another staff member. The nurse should see this client after the more urgent clients and provide the glass of water, as well as monitor the ankle for any signs of complications, such as edema, infection, or impaired circulation.
Choice C reason: This is not the highest priority client because rheumatoid arthritis is a chronic and manageable condition that affects the joints. A scheduled pain medication is a routine and preventive need that can be met by the nurse or another staff member. The nurse should see this client after the more urgent clients and administer the pain medication, as well as assess the joints for any signs of inflammation, stiffness, or deformity.
Choice D reason: This is not the highest priority client because a discharge teaching is a discharge and education need that can be met by the nurse or another staff member. The nurse should see this client last and teach the client how to use the crutches, as well as provide any other discharge instructions, such as wound care, activity restrictions, or followup appointments.
