The nurse is caring for a patient with obesity who is being considered for bariatric surgery. Which do the criteria guidelines for bariatric surgery include?

A. Moist mucous membranes: This is incorrect. In diabetes insipidus, the body loses large amounts of water due to a deficiency of antidiuretic hormone (ADH) or its effects. As a result, the client often experiences dehydration, leading to dry mucous membranes, not moist ones.
B. Bounding peripheral pulses: This is incorrect. While bounding pulses are often seen in conditions like fluid overload or hypervolemia, diabetes insipidus typically causes dehydration due to excessive urination, which would not lead to bounding pulses. The pulses would more likely be weak or thready due to fluid loss.
C. Urine specific gravity 1.002: This is the correct finding. In diabetes insipidus, the kidneys are unable to concentrate urine, resulting in very dilute urine. A urine specific gravity of 1.002 indicates very diluted urine, which is characteristic of diabetes insipidus.
D. Bradycardia: This is incorrect. Bradycardia (slow heart rate) is not typically associated with diabetes insipidus. In fact, tachycardia (increased heart rate) can occur as a compensatory response to dehydration caused by excessive urination in diabetes insipidus.

A. Maintaining an IV of 0.45% sodium chloride would not be appropriate for SIADH because it is a hypotonic solution, and it could exacerbate the already low sodium levels in the patient, potentially worsening hyponatremia.
B. Fluid restriction is the primary treatment for SIADH as it helps reduce water retention, which is causing the dilution of sodium in the blood. Restricting fluid intake to 1,000 mL per day helps manage hyponatremia in these patients.
C. A diet containing 2 g of sodium per day is not typically indicated in SIADH. Restricting fluid is the main focus, and increasing sodium intake can often be counterproductive in SIADH, as the sodium imbalance is primarily due to excessive water retention.
D. Desmopressin acetate is typically used in diabetes insipidus, not SIADH. Desmopressin acts as an antidiuretic hormone (ADH) agonist, which would worsen the water retention in SIADH, not improve it.
