What is a hallmark symptom of diabetic ketoaldosis (DKA)?
Cold sweats
Bradycardia
Cyanosis
Kussmaul respirations
The Correct Answer is D
A. Cold sweats are more commonly associated with hypoglycemia, not DKA.
B. Bradycardia (slow heart rate) is not a typical finding in DKA, where tachycardia is more likely due to dehydration.
C. Cyanosis (bluish discoloration) is seen in severe respiratory or cardiac conditions, not a hallmark of DKA.
D. Kussmaul respirations (deep, rapid breathing) are a hallmark sign of DKA. They represent the body’s attempt to compensate for metabolic acidosis by blowing off excess CO₂.

Correct Answer is B
Explanation
A. The client with an H/H of 12.8 and 38 has lab values within acceptable range for a dialysis patient, especially since anemia is common in this population. This client is stable and does not require immediate assessment.
B. The client who does not have a bruit or thrill in the fistula is the priority. A lack of bruit or thrill may indicate that the arteriovenous (AV) fistula is clotted or not functioning, which is a critical issue. This compromises the client's ability to receive dialysis and requires urgent evaluation.
C. The client who is complaining of fatigue and headache may be experiencing symptoms related to uremia or hypertension, but these are not immediately life-threatening and can be addressed after checking the fistula issue.
D. The client who is complaining of nausea might be experiencing symptoms of fluid overload or uremia, but again, this is less urgent than a potentially non-functioning dialysis access site.
