Document Summary
Fluid and electrolyte balance- lecture part 1: 1st space: Intracellular: where fluid in our cells should be (70%: 2nd space. Interstitial (22%) + intravascular (6%): where we see edema. This is our primary concern: 3rd space, fluid trapped in an abnormal space, common in the peritoneal cavity that results in the ascities. Important electrolytes: sodium (na+): (ecf) primarily an extracellular cation, plays a role in cell action potentials and water balance. Assessing fluid balance: fve: fluid volume excess, fvd: fluid volume deficit, subjective assessment: Intake: too much or too little: urinary output, bowel output: do they have loose stool, diarrhea, nausea/vomiting, energy level, weakness/dizziness, recent activities ( illness, endurance rate, heat exposure, concerned about dehydration. I/o: objective part: sensible and insensible i/o, sensible: that can be measured. Maybe soups: suctioning tools, weighing diapers or linens that are soiled. Insensible: (cid:272)a(cid:374)"t (cid:271)e (cid:373)easured (cid:271)y (cid:374)or(cid:373)al (cid:373)ea(cid:374)s. perpetratio(cid:374) (cid:271)reathi(cid:374)g: fluid balance- sensible/ insensible examples.
