A nurse is reviewing the laboratory results of a client who is dehydrated. Which of the following BUN lab values should the nurse report to the provider?
10 mg/dL.
18 mg/dL.
13 mg/dL.
25 mg/dL.
The Correct Answer is D
25 mg/dL.
Choice A rationale:
A BUN (Blood Urea Nitrogen) level of 10 mg/dL is within the normal range, indicating normal kidney function. There is no indication to report this value to the provider for a dehydrated client.
Choice B rationale:
A BUN level of 18 mg/dL is within the normal range as well. This value does not suggest significant dehydration, so it is not necessary to report it to the provider in this context.
Choice C rationale:
A BUN level of 13 mg/dL is also within the normal range, and similar to choices A and B, it does not indicate severe dehydration that requires immediate reporting to the provider.
Choice D rationale:
A BUN level of 25 mg/dL is elevated, which may indicate dehydration, kidney dysfunction, or other issues affecting fluid balance. Since the client is dehydrated, this elevated value needs to be reported to the provider for further evaluation and appropriate intervention.

Correct Answer is C
Explanation
Choice A rationale:
Sodium level is a laboratory parameter that can be helpful in assessing fluid balance, but it does not directly measure fluid retention. Abnormal sodium levels may indicate fluid imbalances, but it is not the most reliable measure of fluid retention.
Choice B rationale:
Tissue turgor refers to the skin's elasticity, and it can be used to assess dehydration rather than fluid retention. Poor turgor may indicate dehydration, but it does not specifically measure fluid volume increase.
Choice C rationale:
Daily weight is a reliable measure of fluid retention. An increase in weight over a short period may indicate fluid accumulation in the body, while a decrease in weight could signify fluid loss. It is essential to monitor weight consistently under standardized conditions (e.g., same time, same clothing) for accurate assessment.
Choice D rationale:
Intake and output records provide information about fluid intake and output but may not always reflect fluid retention accurately. It is helpful for assessing fluid balance, but daily weight is a more direct and reliable measure of fluid retention.
Correct Answer is C
Explanation
Widened QRS Complexes.
Choice A rationale:
Hyperactive deep tendon reflexes are not typical findings in respiratory acidosis. They are more commonly associated with conditions like hypocalcemia or hypercalcemia.
Choice B rationale:
Warm, flushed skin is not directly related to respiratory acidosis. It is not a typical manifestation of this acid-base imbalance.
Choice C rationale:
Widened QRS complexes on an ECG are characteristic findings in respiratory acidosis. Acidosis can lead to changes in the electrical conduction of the heart, resulting in QRS complex widening.
Choice D rationale:
Bounding peripheral pulses are not directly associated with respiratory acidosis. They may be seen in conditions like hyperthyroidism or anemia but are not specific to respiratory acidosis. Remember, always interpret lab results and clinical findings in the context of the patient's overall condition, medical history, and other relevant factors to provide the best care possible.
