A nurse is administering albumin to a client who has hypovolemic shock due to hemorrhage. The nurse understands that albumin is which of the following types of solutions?

Choice A reason:

Serum sodium is not directly related to the acid-base balance of the body. Sodium bicarbonate therapy does not affect the serum sodium level significantly. Therefore, monitoring serum sodium is not an effective way to evaluate the effectiveness of the therapy.

Choice B reason:

Serum potassium is inversely related to the serum pH. As the pH increases, the potassium level decreases, and vice versa. Sodium bicarbonate therapy raises the pH and lowers the potassium level. Therefore, monitoring serum potassium is important to prevent hypokalemia, but it does not directly reflect the acid-base balance of the body.

Choice C reason:

Serum chloride is inversely related to the serum bicarbonate level. As the bicarbonate level increases, the chloride level decreases, and vice versa. Sodium bicarbonate therapy increases the bicarbonate level and decreases the chloride level. Therefore, monitoring serum chloride is important to prevent hypochloremia, but it does not directly reflect the acid-base balance of the body.

Choice D reason:

Serum bicarbonate is directly related to the acid-base balance of the body. The normal range of serum bicarbonate is 22 to 26 mEq/L. In metabolic acidosis, the bicarbonate level is low, and in metabolic alkalosis, it is high. Sodium bicarbonate therapy aims to increase the bicarbonate level and correct metabolic acidosis. Therefore, monitoring serum bicarbonate is the most effective way to evaluate the effectiveness of the therapy.

Choice A reason:

Applying warm compresses to the site and elevating the arm may help to reduce pain and swelling, but they do not address the underlying cause of the problem, which is likely infiltration or phlebitis of the IV site. Infiltration occurs when the IV fluid leaks into the surrounding tissue, causing edema, coolness, and pallor. Phlebitis occurs when the vein becomes inflamed, causing pain, erythema, and warmth. Both conditions require immediate removal of the IV catheter and restarting a new IV in another site.

Choice B reason:

Slowing down the infusion rate and documenting the findings may be appropriate actions after removing the IV catheter and starting a new IV in another site, but they are not sufficient to resolve the problem. Slowing down the infusion rate may reduce the discomfort and prevent further complications, but it does not stop the leakage or inflammation of the IV site. Documenting the findings is important for legal and quality improvement purposes, but it does not provide any intervention for the patient's pain or risk of infection.

Choice C reason:

Stopping the infusion, removing the IV catheter, and starting a new IV in another site is the most appropriate action by the nurse. This action prevents further damage to the tissue or vein, reduces the risk of infection, and restores adequate IV access for fluid and medication administration. The nurse should also apply a sterile dressing to the affected site, monitor for signs of infection or complications, and notify the physician if needed. This is the correct answer.

Choice D reason:

Notifying the physician and obtaining an order for an antihistamine is not an appropriate action by the nurse. This action implies that the patient is having an allergic reaction to the IV fluid or medication, which is not supported by the assessment findings. An antihistamine may help to reduce itching or swelling, but it does not address the cause of the pain or prevent further tissue or vein damage. The nurse should notify the physician after removing the IV catheter and starting a new IV in another site, and only if there are signs of infection or complications that require medical intervention.
