- The following is the major extracellular electrolyte diffusing from the ECF into the ICF across a selectively permeable cell membrane O a Na O b. Ca OCP Odk OeoThe major role of this electrolyte is to maintain osmotic pressure in the extracellular fluid (ECF). a. HCO3– b. Ca2+ c. Na+ d. K+A 5% dextrose is isoosmotic to plasma. What effect would infusion of 1L of a 5% dextrose solution have on ECF and ICF volumes? How it would affect body fluid osmolality of a 70 kg individual and why?
- List the effects of each of the following hormones on electrolyte balance. Note that some hormones affect more than one electrolyte. a. Angiotensin-II b. Aldosterone c. Parathyroid hormone d. Vitamin D e. Atrial natriuretic peptideWater and electrolytes enclosed by cell membranes constitute the .a. transcellular fluidb. intracellular fluidc. extracellular fluidd. lymphAn inadequate (low) dietary intake of NaCl will cause A) increased angiotensin II production
- Which of the following electrolytes can be described as: regulated by aldosterone, controls skeletal and smooth muscles, and is the most common cation. A. Na+B. K+C. Ca+D. Cl-Patient with dehydration was started on fluid therapy. If 5% dextrose is isoosmotic to plasma what effect would infusion of 1L of a 10% dextrose solution have on ECF and ICF volumes? How it would affect body fluid osmolality of a 70 kg individual and why?Which of the following depend (s) on the presence of electrolytes? a. membrane polarity b. neuromuscular excitability c. maintenance of osmotic relations between cells and ECF d. blood glucose levels
- Blood volume must be restored in a person who has lost large amounts of blood due to serious injury. This is often accomplished by infusing isotonic NaCl solution into the blood. Why is this more effective than infusing an isoosmotic solution of a penetrating solute, such as urea?water movement in and out cells is due mainly to fluctuation of the na+ and k+ ion concentrationsMany blood pressure medications block the reabsorption of water in the collecting ducts. How would this affect using output and concentration.
