NUR 172 IV Therapy Exam (all solved)

Isotonic Solutions correct answers D5W (dextrose 5% in water) NS (0.9% NaCl) LR (Lacated ringers) D5 1/4 NS ( Dextrose 5% in 0.225% NaCl) Albumin 5% What is a isotonic solution? correct answers The concentration of solutes is equal inside and outside the cell so water moves across the membrane in both directions maintaining cell size. =No major fluid shift Hypotonic Solutions correct answers *must be less than 0.9% NS 1/4 NS (0.225% NaCl) 1/2 NS (0.45% NaCl) D2.5W (Dextrose 2.5% in water) 1/3 NS (0.33% NaCl) What is hypotonic solution? correct answers This solution moves the fluid from the vessel into the cell. This is used for treating dehydration. The cell will SWELL from the flow of fluid intake. Hypertonic Solutions correct answers *must be greater than 0.9% NS & two solvents together D5 in NS (Dextrose 5% in NaCl) D5 in LR (Dextrose 5% in Lactated Ringers) D5 in 1/2 NS (Dextrose 5% in 0.45% NaCl) TPN PRC (packed red blood cells) Albumin 25% What are the cautions with administering hypotonic solutions in regards to tonicity? correct answers Caution: Pt's should be assessed for CVA, Head trauma, IICP, or pt's with low BP before receiving this solution What are the cautions with administrating hypertonic solutions in regards to tonicity? correct answers Caution: High BP, Heart or kidney failure/disease could cause fluid overload with this solution What is a hypertonic solution? correct answers Solute concentration is greater than that inside the cell. Cell loses water which will move into the vessel and the cell SHRINKS. How do you calculate ml/hr? correct answers You multiply the given ml and divide it by the hour given. What is the normal BUN value? correct answers 10-20 What is the normal potassium level? correct answers 3.5-5
