Mrs Jones is a 55 year old woman, she is 5'6" tall and weighs 140 lbs (63.6 kg). She has suffered a stroke and is unable to eat; therefore, she is receiving a tube feeding. The tube feeding ordered for her provides: 1 calorie/mL and 40 grams of protein/1000 mL. It is infusing at a rate of 50 mL/hour for 24 hours. Hints: Calorie needs: Since she is close to an ideal weight and is considered noncritical care, use the formula of 30 calories per kg of weight (page 142) Protein needs: Use the RDA for adults of 0.8 gms protein per kg of weight (page 50, note that some experts think that a range of 1.0 to 1.2 may be beneficial) Volume: mL per hour x hours of feeding = total volume of feeding Calories provided by tube feeding: number of calories per mL x total volume of feeding = total calories Protein provided by tube feeding: grams of protein per liter (1000 mL) x total liters of feeding provided = grams of protein. [Liters of formula = volume of formula / 100.] 1

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
