A client with suspected Nephrogenic Diabetes Insipidus asks the nurse about the diagnostic tests they may undergo. What test measures the concentration of urine to assess the kidney's ability to reabsorb water?
Blood glucose test
Urine osmolality test
Electrocardiogram (ECG)
Complete blood count (CBC)
The Correct Answer is B
A) Incorrect. A blood glucose test measures the concentration of glucose in the blood and is not specific to diagnosing Nephrogenic Diabetes Insipidus.
B) Correct. The urine osmolality test assesses the concentration of solutes in the urine, providing information about the kidney's ability to reabsorb water. In Nephrogenic Diabetes Insipidus, urine osmolality remains low even when a person is dehydrated.
C) Incorrect. An electrocardiogram (ECG) is a test used to evaluate the electrical activity of the heart and is not specific to diagnosing Nephrogenic Diabetes Insipidus.
D) Incorrect. A complete blood count (CBC) measures various components of the blood, such as red blood cells, white blood cells, and platelets. It is not specific to diagnosing Nephrogenic Diabetes Insipidus.

B) Incorrect. Autosomal recessive Nephrogenic Diabetes Insipidus is inherited in an autosomal recessive manner, not as an X-linked recessive trait.
C) Incorrect. X-linked dominant inheritance is not associated with Nephrogenic Diabetes Insipidus. This condition can be caused by mutations in the AVPR2 gene (X-linked recessive) or the AQP2 gene (autosomal recessive).
D) Correct. X-linked recessive Nephrogenic Diabetes Insipidus is caused by mutations in the AVPR2 gene located on the X chromosome. It primarily affects males who inherit the mutated gene from their carrier mothers.
