A client is admitted with diabetic ketoacidosis (DKA) and is receiving an IV infusion of 0.9% sodium chloride and insulin. Two hours later, the client's serum laboratory results show a decrease in the serum blood glucose from 580 to 430 mg/dL (32.2 to 23.86 mmol/L). It is most
important for the nurse to monitor which additional laboratory result?
Reference Range

- Decreased hemoglobin and hematocrit levels: Consistent with iron deficiency anemia, vitamin B12 deficient anemia, and folic acid deficient anemia. Iron deficiency anemia results from
inadequate iron stores, while vitamin B12 deficient anemia and folic acid deficient anemia are characterized by inadequate levels of these respective vitamins, all of which contribute to decreased hemoglobin and hematocrit levels.
- Uptake often impeded by medications: Consistent with iron deficiency anemia and vitamin B12 deficient anemia. Iron absorption can be affected by certain medications, such as proton pump
inhibitors or antacids, which can hinder iron uptake. Vitamin B12 deficiency can result from medications that interfere with its absorption, such as proton pump inhibitors or metformin.

- Often associated with chronic alcoholism: Consistent with vitamin B12 deficient anemia. Chronic alcoholism can lead to vitamin B12 deficiency due to poor dietary intake,
malabsorption, or liver dysfunction associated with excessive alcohol consumption.

- Can be caused by malabsorption syndrome: Consistent with vitamin B12 deficient anemia and folic acid deficient anemia. Malabsorption syndromes, such as celiac disease or Crohn's disease, can impair the absorption of both vitamin B12 and folic acid from the gastrointestinal tract,
leading to deficiencies.

- Result of dietary deficiency: Consistent with iron deficiency anemia, vitamin B12 deficient anemia, and folic acid deficient anemia. Iron deficiency anemia results from inadequate dietary intake of iron-rich foods, while vitamin B12 deficient anemia and folic acid deficient anemia stem from insufficient dietary intake of foods rich in these respective vitamins.

A. While scheduling a client and family conference may be necessary to discuss the plan of care, the immediate concern is to determine the type of advance directive the client has and whether it includes preferences regarding resuscitation.
B. This is the most appropriate action because it addresses the family member's concern and ensures that the client's wishes regarding resuscitation are understood and followed.
C. While checking for a DNR bracelet is important, it does not address the family member's question about why the code was called despite the client having a living will.
D. This statement is incorrect. Living wills can guide decision-making regarding end-of-life care, including resuscitation, depending on the legal requirements and documentation in place.
