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:

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.

Choice A reason: Thrombophlebitis is characterized by inflammation of the vein with the formation of a blood clot. The signs and symptoms include erythema, warmth, edema, and a red line traveling up the vessel, which indicates the presence of inflammation and possible clot formation. This condition requires prompt intervention to prevent further complications such as the spread of infection or the clot traveling to other parts of the body.

Choice B reason: Infiltration occurs when IV fluid or medication leaks into the surrounding tissue. Signs of infiltration include swelling, discomfort, and coolness at the IV site, but it does not typically present with erythema, warmth, or a red line traveling up the vessel. Infiltration is less likely to cause the systemic signs seen in this case.

Choice C reason: Infection at the IV site can cause erythema, warmth, and edema, but it usually does not present with a red line traveling up the vessel. The red line is more indicative of thrombophlebitis, where the inflammation follows the path of the vein. Infection would also likely present with additional systemic signs such as fever.

Choice D reason: Extravasation involves the leakage of vesicant drugs into the surrounding tissue, causing severe local tissue damage. Signs include pain, burning, and blistering at the site, but it does not typically present with a red line traveling up the vessel. Extravasation is more localized and does not follow the vein’s path like thrombophlebitis.
