Answer:
When portable transport ventilator alarms are ringing, the priority nursing assessment includes to check if, all the tubes of ventilators are connected properly or not because sometimes movement of the patient can disconnect the tubes.
Sometimes, obstruction of the Endotracheal tube (ETT) from mucus plugs or from patients biting on the tube, causes ringing of alarm and should be assessed on a priority basis.
Answer: Option E
Explanation:
Liver is a large reddish brown organ that is responsible for various types of function. It deals with many functions.
Some of them includes: Lipid emulsification, iron storage, Gluconeogenesis and glycogen storage.
It does not helps in the secretion of digestive enzymes secretion. Liver produces bilivirdin and bilirubin(yellowish fluid)which helps in the emulsification of fat droplets but bilivirdin and bilirubin are not digestive enzymes.
Hence, the correct answer is" option E".
Answer:
Okay
Explanation:
Human topoisomerase I plays an important role in removing positive DNA supercoils that accumulate ahead of replication forks. It also is the target for camptothecin-based anticancer drugs that act by increasing levels of topoisomerase I-mediated DNA scission. Evidence suggests that cleavage events most likely to generate permanent genomic damage are those that occur ahead of DNA tracking systems. Therefore, it is important to characterize the ability of topoisomerase I to cleave positively supercoiled DNA. Results confirm that the human enzyme maintains higher levels of cleavage with positively as opposed to negatively supercoiled substrates in the absence or presence of anticancer drugs. Enhanced drug efficacy on positively supercoiled DNA is due primarily to an increase in baseline levels of cleavage. Sites of topoisomerase I-mediated DNA cleavage do not appear to be affected by supercoil geometry. However, rates of ligation are slower with positively supercoiled substrates. Finally, intercalators enhance topoisomerase I-mediated cleavage of negatively supercoiled substrates but not positively supercoiled or linear DNA. We suggest that these compounds act by altering the perceived topological state of the double helix, making underwound DNA appear to be overwound to the enzyme, and propose that these compounds be referred to as ‘topological poisons of topoisomerase I’
Yes. when ever you get drugs from the pharmacy. they always give you too many. and usually when you go back to get a refill. they don’t ask your doctor if you need them. they are part of the blame due to negligence
