The recommended guideline for determining suction catheter depth when suctioning an endotracheal tube is;
<u><em>By using a suction catheter with centimeter increments on it.</em></u>
<u><em>Insert the suction catheter into the endotracheal tube until the centimeter markings on both the endotracheal tube and catheter align</em></u>
<u><em>Insert the suction catheter no further than an additional 1 cm.</em></u>
<u><em /></u>
From documented guidelines to determine suction catheter depth, they are;
1) Get a suction catheter with centimeter increments on it.
2) Then you will Insert the suction catheter into the endotracheal tube till the centimeter markings located on both the endotracheal tube and catheter align
3) Next is to insert the suction catheter not more than an extra 1 cm.
4) The length of the endotracheal tube should be combined with any other adapter you are using after which you add an additional 1 cm.
5) Get a spare <em>endotracheal tube</em> that has same size as that being used for the patient.
6) Insert the suction catheter to the end of this tube and take note of the length at which the catheter got to the end of the tube.
7) If you are dealing with a closed system, then all you need to do is to combine the endotracheal tube length and length of additional adapters you are using and add an extra 1 cm.

Answer:
Explanation:
lower frequency is the answer
Answer:
a. The directionality of the complementary strand is antiparallel. The double-stranded DNA is antiparallel comprising two strands, which run alongside each other, however, point in reverse directions. In a double-stranded molecule of DNA, the 5 prime ends of one strand align with the 3 prime ends of the other strand, and vice versa.
b. The mediation of base pairing is done by non-covalent hydrogen bonds. It is reversible, that is, the strands can separate and can come combined again without any chemical modification.
The specificity of base pairing is illustrated by hydrogen bonds that is, the first strand produces hydrogen bonds only with a particular base in the second strand, and these two bases produce a base-pair.
c. The interaction or association of non-covalent type, that is, hydrophobic interaction and hydrogen bonding. Collectively, they both are strong. In the process, one base associate with the other base on the complementary strand.
d. The phosphate backbone possesses the tendency to associate with water on the outside of the molecule, and this is favorable chemically as both the strands are held together by hydrogen bond and hydrophobic interaction.
The polar molecules of sugar can produce hydrogen bonds with the surrounding molecules of water. The negatively charged phosphate group associate with the positively charged ions. The nonpolar nitrogen bases are found within the molecule and associate favorably through stacking interactions.
