How should the critical care nurse most accurately titrate the dose and frequency of administration of an intragastric drip of a

The critical care nurse most accurately titrate the dose and frequency of administration by aspirating stomach contents and measuring the pH.
For patients with a nasogastric tube in place, antacid dosage may be titrated by aspirating stomach contents, determining pH, and then basing the dose on the pH. Accurate measurement of gastric pH cannot be determined from the buccal mucosa or urine.

<h2>It could be made by aspirating stomach contents and regulating the pH. </h2>

Gastric contents or continuous pH graduating with a terminal of pH monitoring with the gastric aspiration system is a constant and reproducible process. For victims with a nasogastric tube in position, antacid dosage may be titrated. By aspirating abdomen contents, discovering pH, and then fixing the dose on the specific pH. Absolute determination of gastric pH cannot be discovered from the buccal mucosa or urine of an individual.

The reason that there are Okazaki fragments during DNA replication is ultimately because:
rusak2 [61]

Answer:

B) Polymerases can only synthesize in the 5' to 3' direction

Explanation:

The leading strand's directionality is 3' to 5', so polymerase has no problem with replicating this one. But the lagging strand has the opposite directionality, so the polymerase must work in the opposite direction of the replication fork.In consequence, the replication process undergoes periodic breaks, and the enzymes have to stop and start again while helicase separates both strands, resulting in the polymerization of okazaki fragments.

8. The letter p in the term pH stands for the German word
pychu [463]

Answer:

Here's what I get  

Explanation:

Per the above explanation, pH means "power of hydrogen ions."

The concentration of hydrogen ions is a measure of the acidity of a solution. A higher concentration represents a more acidic solution.

The definition of pH is

pH = -log[H⁺]

Thus, pH is a measure of the hydrogen ion concentration.

The more negative the pH, the greater the Potenz of hydrogen ions.

Describe both innate and acquired immune systems and the importance of vaccines.
lbvjy [14]

Answer:

Innate immunity is a non-specific immune system which provides defence against any pathogenic microorganism in early stages. It includes physical barrier such as skin, chemical barriers such as saliva, tears, et cetera, phagocytic cells such as macrophages, et cetera.

Acquired immune system is the one which develops after exposure to pathogen or antigen. It is highly specific in nature. It includes B-lymphocytes and T-lymphocytes. It includes the production of antibodies.

Vaccines are used to develop acquired immunity in people. The process is termed as vaccination or immunisation. Heat-killed or weakened pathogen or antigen is inserted into a person after which a person develops antibodies and memory cells against that pathogen or disease. So, the immune system acts more vigorously against that pathogen in secondary infection.

Thus, a person becomes immunised.

Where does RNA polymerase begin transcribing a gene into mRNA?
IrinaK [193]

Answer:

The correct answer will be option-B

Explanation:

The process of transcription transcribes the sequence of the bases of genes present on DNA to mRNA which acts as a messenger molecule for the protein synthesis.

The process of transcription is mediated by the presence of enzymes which includes the main transcription enzyme called RNA polymerase. RNA polymerase attaches nucleotides to RNA strand.

The transcription process initiates in three stages: initiation, elongation and termination.  

The initiation process begins when RNA polymerase binds to the promoter nucleotide sequence which is present at the start site or the upstream on DNA towards 5' end.

Thus, Option-B is the correct answer.

When mitosis occurs, the DNA inside the cell's nucleus must replicate. The new cell that is formed has an identical copy of its
Tanzania [10]
The answer is <span>DNA polymerases add nucleotides to the exposed base pairs according to base-pairing rules.

DNA polymerase performs the polymerization of DNA. It adds nucleotides to the new DNA strand according to the base-pairing rules. This means that adenine binds to thymine and guanine binds to cytosine. The DNA polymerase is important enzyme responsible for accurate DNA  replication.

Choice 2 is incorrect because DNA does not contain uracil.
Choice 3 is incorrect because helicase untwists DNA.</span>
