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 A
Explanation
Choice A rationale:
The client with a phosphate level of 5.7 mg/dL likely has a manifestation of hypoparathyroidism. Hypoparathyroidism leads to decreased parathyroid hormone (PTH) secretion, which causes increased renal phosphate reabsorption, leading to elevated phosphate levels in the blood.
Choice B rationale:
A calcium level of 9.8 mg/dL is within the normal range (8.5-10.2 mg/dL) and does not indicate hypoparathyroidism.
Choice C rationale:
A vitamin D level of 25 ng/mL is within the normal range (30-100 ng/mL) and does not suggest hypoparathyroidism.
Choice D rationale:
A magnesium level of 1.8 mEq/L is within the normal range (1.7-2.2 mEq/L) and does not directly indicate hypoparathyroidism.
Correct Answer is A
Explanation
Urine specific gravity 1.020.
Choice A rationale:
Urine specific gravity is a measure of urine concentration, indicating the ability of the kidneys to concentrate or dilute urine. A specific gravity of 1.020 falls within the normal range (typically 1.010 to 1.030). An appropriate specific gravity indicates that the client's kidneys are responding well to the IV fluids, maintaining adequate urine output and concentration.
Choice B rationale:
Potassium level of 5.2 mEq/L is above the normal range of 3.5 to 5 mEq/L. However, this value does not specifically indicate whether the client is responding effectively to the IV fluids for dehydration.
Choice C rationale:
Hct (Hematocrit) of 6296 is not a valid measurement; it appears to be a typographical error or an incomplete value. Therefore, it cannot be used to assess the client's response to treatment.
Choice D rationale:
Sodium level of 165 mEq/L is elevated beyond the normal range of 136 to 145 mEq/L. However, this value does not provide information about the client's response to IV fluids for dehydration.
