Which hormone should the nurse focus on assessing based on Mr. Jermaine's symptoms?

• A. Insulin
• B. Antidiuretic hormone (ADH)
• C. Cortisol
• D. Thyroxine (T4)

Answer: (B)

In considering Mr. Jermaine's symptoms, focusing on antidiuretic hormone (ADH) is particularly pertinent if he is exhibiting signs such as excessive thirst, frequent urination, or changes in fluid balance. ADH is critical in regulating the body's water balance and blood pressure. It acts primarily on the kidneys to promote water reabsorption, which can be disrupted in various conditions, leading to symptoms associated with diabetes insipidus, syndrome of inappropriate antidiuretic hormone secretion (SIADH), or other related disorders.

Evaluating ADH allows the healthcare provider to ascertain fluid regulation issues that might be underlying Mr. Jermaine's presenting symptoms. The importance of this hormone in maintaining homeostasis makes it a focal point in assessment, especially if the symptoms suggest dehydration or fluid overload. Addressing abnormalities in ADH levels can significantly impact patient care, including adjustments in fluid management and potential treatments.
