The nurse is working on a cardiac unit with several patients who have intravenous access lines. The nurse identifies the following are considered central venous catheters: (Select All That Apply)

A. Respiratory acidosis.

COPD is a chronic lung disease that can lead to an accumulation of carbon dioxide (CO2) in the body. This can cause respiratory acidosis, a condition in which the blood pH is lower than normal due to an excess of CO2.

In respiratory acidosis, the partial pressure of carbon dioxide (PaCO2) in the blood is increased and the pH is decreased. The kidneys atempt to compensate for the acidosis by excreting more acid in the urine and retaining more bicarbonate, but this compensation is usually not enough to fully correct the problem.

Metabolic alkalosis (option B) is a condition in which the blood pH is higher than normal due to an excess of bicarbonate in the blood. This is usually caused by loss of acid from the body, such as through vomiting or use of diuretics.

Respiratory alkalosis (option C) is a condition in which the blood pH is higher than normal due to a decrease in PaCO2. This can be caused by hyperventilation, which leads to excessive elimination of CO2 from the lungs.

Metabolic acidosis (option D) is a condition in which the blood pH is lower than normal due to an excess of acid in the blood. This can be caused by a variety of factors, including kidney failure or lactic acidosis.

: A client with renal disease may have impaired kidney function, which can affect fluid balance in the body. Giving fluids too quickly or increasing the infusion rate too quickly can lead to fluid overload,

which can exacerbate the client's condition. It is important for the nurse to monitor the amount of fluid the client is receiving to ensure that the infusion rate is appropriate for the client's condition and to prevent fluid overload. Checking the intravenous rate every two days is not sufficient; the nurse should monitor the rate regularly and adjust it as necessary based on the client's response.
