A nurse is caring for a client who had an arterial blood gas drawn. The pH on the ABG is 7.10. What acid-base imbalance does this client have?

Choice A reason: Cover

Covering a wound with slough is not an appropriate intervention. Slough is a type of necrotic tissue that can impede the healing process by providing a medium for bacterial growth and preventing the formation of healthy granulation tissue. Simply covering the wound without addressing the slough can lead to infection and delayed healing.

Choice B reason: Clean

Cleaning the wound is a necessary step in wound care, but it is not sufficient on its own to address the presence of slough. While cleaning can help reduce the bacterial load and remove some debris, it does not effectively remove the slough itself. Slough often requires more targeted interventions such as debridement to be effectively managed.

Choice C reason: Debride

Debridement is the most appropriate intervention for a wound with slough. Debridement involves the removal of necrotic tissue, including slough, to promote a clean wound bed and facilitate the healing process. There are several methods of debridement, including autolytic, enzymatic, mechanical, and surgical, each with its own indications and benefits. Removing the slough allows for better assessment of the wound and promotes the formation of healthy granulation tissue.

Choice D reason: Leave Alone

Leaving a wound with slough alone is not advisable. Slough can harbor bacteria and impede the healing process, leading to chronic wounds and potential infection. Without intervention, the wound is unlikely to progress through the normal stages of healing.

Choice A Reason:

Restlessness is often one of the earliest signs of hypoxia. When the body experiences low oxygen levels, the brain is one of the first organs to be affected. This can lead to symptoms such as anxiety, agitation, and restlessness as the brain struggles to function properly without adequate oxygen. These symptoms occur because the body is trying to compensate for the lack of oxygen by increasing respiratory and heart rates, which can make a person feel uneasy or restless.

Choice B Reason:

Cyanosis refers to a bluish discoloration of the skin and mucous membranes due to low oxygen levels in the blood. While cyanosis is a significant indicator of hypoxia, it is typically a later sign. By the time cyanosis is visible, hypoxia has usually been present for some time, and oxygen levels have been critically low. Therefore, it is not the earliest clinical manifestation of hypoxia.

Choice C Reason:

Apnea is the absence of breathing. This is a severe and late sign of hypoxia. When a person stops breathing, it indicates that the body has been deprived of oxygen for an extended period, leading to critical conditions. Apnea is a medical emergency and requires immediate intervention, but it is not an early sign of hypoxia.

Choice D Reason:

Bradycardia is a slower than normal heart rate. Like apnea, bradycardia is a late sign of hypoxia. Initially, the body responds to low oxygen levels by increasing the heart rate (tachycardia) to pump more oxygenated blood to tissues. Bradycardia occurs when the body can no longer compensate, and the heart rate slows down, indicating severe hypoxia and impending failure of the cardiovascular system.
