A patient is receiving Dextrose 5% in 0.45% Sodium Chloride Injection and 40 mEq of potassium chloride in a total volume of 1000 mL through an IV set that delivers 15 drops per ml. The IV fluid has been running at a rate of 12 drops per minute for 15 hours. Molec Weights: Dextrose = 180, Na = 23, K = 39, CI = 35.5 1. How many mEq of potassium chloride have been administered so far? K = 39;...

A patient is ordered to receive chloride supplementation by intravenous infusion of a sodium chloride solution [Na CI, MW-58.44 g/mol). The patient is ordered to receive 0.7 mEq of CI - ions per hour. A 750 mL intravenous bag is prepared that contains 17 mL of a 14.6% solution of sodium chloride. What should be the infusion rate (in units of mL/min) necessary to produce the ordered dose of 0.7 mEq/hr of chloride? (Note: Consider the total solution volume to...

A 7% solution of sodium chloride (Na Cl - MW = 58.44 g/mol) has been prepared by a technician for direct intravenous injection to a patient. While reviewing the order and preparation, you recall that this concentration seems to be abnormal. As a result, you want to determine the osmolarity of the solution. What is the osmolarity of this solution? Note: Please provide your answer in units of mOsmol/L.

GIVEN: The following are the atomic masses of particular elements: Na = 23 Cl = 35 Mg = 24 Assuming the membrane is relatively impermeable to the following substances, what will happen to RBCs placed in these solutions? (HINT: need to think in terms of osmolarity!): a) 0.2 M MgCl2 (Answer: it shrinks or crenates) b) 0.2% NaCl (Answer: it swells and perhaps lyses) Please explain how to get the answers provided. Thanks!
