Chapter 39, Fluid, Electrolyte, and Acid-Base Balance

1. Which body Ӑuid is the Ӑuid within the cells, constituting about 70% of the total body water? A) Extracellular Ӑuid (ECF) B) Intracellular Ӑuid (ICF) C) Intravascular Ӑuid D) Interstitial Ӑuid Ans: B Feedback: Intracellular Ӑuid is the Ӑuid within the cells, constituting about 70% of total body Ӑuid. Extracellular Ӑuid is all Ӑuid outside the cells and includes intravascular and interstitial Ӑuids. 2. Based on knowledge of total body Ӑuids, a nurse is especially watchful for a Ӑuid volume deӐcit in an infant. Why would the nurse do this? A) Infants have less total body Ӑuid and ECF than adults. B) Infants have more total body Ӑuid and ECF than adults. C) Infants drink less Ӑuid than adults. D) Infants lose more Ӑuids through output than adults. Ans: B Feedback: An infant has considerably more total body Ӑuid and ECF than an adult does. Because ECF is more easily lost from the body than ICF, infants are more prone to Ӑuid volume deӐcits.
