Aspiration of Urine can be obtained by catherization. This procedure is performed by using a sterile urinary catheter inserted into the urethra into the bladder where gravity will pull the urine into a collection device. There is another type of aspiration that can be done using a very long needle inserted via puncture into the bladder but this is more invasive & not the first choice.
The sponge is a very porous structure, while the soap us more solid.
C. Median toxicity.
Explanation – The frequency of drugs are given based on its toxicity or the side effects in the body. All drugs have certain half-life in which there action is maximum and after that the drug is removed through the urine primarily.
Different people react differently to a drug and hence the doctors prescribe the anti-tablets for the side effects occurring. The drug for cold is prescribed after four hours because its effect gets reduced and has to be removed from the body.
D, perspiration (which is also known as sweating).
