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’
The most typical types of dressing used to secure central venous catheters are gauze and tape or transparent polyurethane film dressings like Tegaderm, Opsite, or Opsite IV3000 (CVCs). There aren't any established rules for what kind of attire is most appropriate right now.
- Apply clean gloves, put on a face mask, cover the client's face with a mask, and wash your hands.
- Assess the insertion site after removing the old dressing and CHG-impregnated patch
- Throw away the clean gloves, wash your hands, and put on sterile gloves.
- Cleanse the area with CHG using friction for at least 30 seconds, then let it thoroughly air dry.
- Cover the catheter insertion site with a sterile transparent dressing after applying a CHG patch.

Answer:
The correct answer to the question: When the pH of the extracellular fluid drops, the kidneys:____, would be: C: excrete fewer bicarbonate ions.
Explanation:
The pH of the human body, given by the extracellular fluid that flows and is contained in it, holds a narrow margin between 7.35 and 7.45. When hydrogens ions increase, and bicarbonate ions decrease, in any of these fluids, be it blood, CSF, or any other, then we known that a person´s body is going into acidosis because the pH level is dropping. However, when the scenario is the opposite, with more bicarbonate ions, than hydrogen ions, then we are talking of an alkalosis. In order for the body to restore its normal levels, it has a series of mechanisms that will ensure the reestablishment of balance. One such mechanism is the excretion of elements through the urine, by the kidneys. In a case of acidosis then, the correct procedure is that kidneys produce urine charged with the excess hydrogen atoms and re-uptakes bicarbonate ions that might have escaped while producing urine. The urine will become acidic then. This is why the answer is C.
Answer:
4ml
Explanation:
80 × 0.25 = 20
Patient will need 20mg/day;
There are 50mg in 10ml, and we the patient needs 20mg so we can use ratios;
50 : 10
20 : x
20/50 = x/10
x = 4ml
