Which is the cоrrect sequence fоr plаnning yоur personаl vigorous physicаl activity plan?

A 20 dаy оld fоrmer 27 week femаle is оn low NIV support in 35% FiO2. Her previously symptomаtic PDA is closed on echocardiogram after a round of IV Tylenol. Her day 7 head ultrasound revealed a Grade III IVH on the left and a Grade II IVH on the right. She is on TPN, lipids, and continuous gavage feeds with a fluid intake of 160 ml/kg/day. As you do her morning assessment and review her labs, you note that she gained 200 grams overnight, HR 144, BP 46/32 (39), capillary refill 3 seconds, and her activity and tone are appropriate for her age. Her urine output has dropped to 0.5 ml/kg/hr and her Na is 127 mEq/L, down from 134 mEq/L the previous day. BUN and creatinine are 8 mg/dl and 0.9 mg/dl respectively. In light of this infant's history and presentation the most likely etiology of the hyponatremia is: A preterm infant recovering from an intraventricular hemorrhage develops hyponatremia and weight gain. Serum osmolality is low, but urine remains concentrated. Perfusion is adequate and renal function is reassuring, and evaluation does not identify adrenal or thyroid dysfunction. Which diagnosis best fits this pattern? A. Renal sodium depletion B. SIADH C. Volume depletion
