A client states that he has been experiencing oozing from his wound. What is the nurse's priority assessment for this client?

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: Determine whether it is temporary or permanent is not the nurse's priority action for a client with compromised immunity, because it is not the most urgent and relevant. Determining whether the compromised immunity is temporary or permanent is an important assessment, but it should be done after ensuring the safety and infection prevention of the client. Compromised immunity can be temporary or permanent, depending on the cause, such as medication, disease, or genetic disorder.

Choice B reason: Take the client's vital signs every four hours is not the nurse's priority action for a client with compromised immunity, because it is not the most urgent and relevant. Taking the client's vital signs every four hours is an important monitoring, but it should be done after ensuring the safety and infection prevention of the client. Vital signs can indicate the general health status and the presence of infection or inflammation, such as fever, tachycardia, or hypotension.

Choice C reason: Teach the family members to receive the flu shot annually is not the nurse's priority action for a client with compromised immunity, because it is not the most urgent and relevant. Teaching the family members to receive the flu shot annually is an important education, but it should be done after ensuring the safety and infection prevention of the client. The flu shot is a vaccine that can protect the family members and the client from influenza, which can be a serious and potentially fatal infection for people with compromised immunity.

Choice D reason: Wash hands before entering the client's room is the nurse's priority action for a client with compromised immunity, because it is the most urgent and relevant. Washing hands before entering the client's room is a basic and essential infection prevention measure, which can protect the client from exposure to pathogens that can cause infection. People with compromised immunity have a weakened or impaired immune system, which makes them more susceptible and vulnerable to infection.
