Which client is at highest risk of compromised immunity?

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: Flushing the exposed skin with water is the first action that the nurse should take if they are stuck by a needle. This is to reduce the amount of blood or body fluid that may have entered the wound and to prevent infection. The nurse should flush the skin for at least 15 minutes and avoid using soap, antiseptic, or bleach as they may damage the skin or increase the risk of infection.

Choice B reason: Reporting the exposure is the second action that the nurse should take after flushing the exposed skin with water. This is to inform the supervisor, the occupational health department, or the infection control team about the incident and to initiate the postexposure protocol. The nurse should provide the details of the exposure, such as the type and source of the needle, the depth and location of the wound, and the status of the source patient.

Choice C reason: Seeking medical attention is the third action that the nurse should take after reporting the exposure. This is to receive a medical evaluation and treatment, such as testing, prophylaxis, counseling, and followup. The nurse should consult a health care provider as soon as possible and follow the recommendations for preventing or treating any potential infections, such as hepatitis B, hepatitis C, or HIV.

Choice D reason: Completing an incident report is the last action that the nurse should take after seeking medical attention. This is to document the exposure and the actions taken and to identify the causes and the preventive measures for the future. The nurse should fill out the incident report form accurately and objectively and submit it to the appropriate authority. The incident report is not a part of the client's record and should not be mentioned in the client's chart.
