For fluid resuscitation in hemorrhagic shock, give about _____ of crystalloid for every _____ of blood lost.
Agata [3.3K]

For fluid resuscitation in hemorrhagic shock, about 3 ML of crystalloid for every 1 ML blood lost. 3 L of fluid needs to administered to raise the intramuscular volume by 1L.

Fluid administration should continue until the patient's hydrodynamics become stabilized. Crystaloids quickly leak from vascular space, fluid expands the blood volume by 20-30% . Lactated ringer's solution is used balanced salt solution for fluid resuscitation in hemorrhagic shock.

Colloid solution are generally not used. Those who have dehydration and adequate circulatory volume typically free water deficit and hypo-tonic solutions.Lost blood volume with intravenous fluids called crystalliods. Consistency of liquid is thin and saline solution.

alexandr1967 [171]

Answer: A molecule of a compound is formed by bonding atoms of different elements through chemical bonding. The number of each type of atom present in one molecule of the compound is represented by a suffix to the symbol of the element which representing the formula of the compound. C12H22O11 is a formula of a compound consists of carbon, hydrogen and oxygen elements. There are 12 carbon atoms, 22 hydrogen atoms and 11 oxygen atoms in one molecule of C12H22O11. Therefore, the numbers 12, 22 and 11 represent number of atoms.

zhenek [66]

Answer:

The answer is mother in meiosis II

Explanation:

nondisjunction can be defined as the failure of the segregation of the child chromosomes in meiosis I and meiosis II resulting in gametogenes. This results in abnormal gametes with some chromosomal imbalance being formed and subsequent fertilization of these gametes results in a generation of abnormal individuals.

According to exercise, red-green color blindness follows an X-linked recessive pattern and the phenotype is only expressed. the father cannot bring the possibility of color blindness to his children, and the nondisjunction, defined earlier, cannot occur in either meiosis I or meiosis II. As a conclusion we can say that it may have a place in meiosis I or meiosis II corresponding to the mother and although the mother's condition may be normal, the first child would be compromised with color blindness, therefore, the mother is the carrier.
