what is the highest risk of exposure to hazardous drugs?

Answers

The highest risk of exposure to hazardous drugs occurs during the preparation of the drugs because they are at their most concentrated state.

Hope this helps you!

Because the hazardous substances are in their most concentrated form when they are being prepared, this is the phase of the process that has the greatest potential for exposure to the substances.

What are hazardous drugs?

A drug is considered to be hazardous if it exhibits one or more of the following characteristics in experimental animals: genotoxicity, carcinogenicity, teratogenicity, or fertility impairment; serious organ or other toxic manifestation at low doses; or serious organ or other toxic manifestation at low doses.

I always get full but there are only 1-3 bites left on my plate. Why does this happen?

Answers

Answer:

First bite syndrome is a side effect of some surgical treatments for head and neck cancer that is thought to be caused by nerve damage. It can also be caused by a head and neck tumor itself. The syndrome causes pain in the mouth that is triggered by salivation or when taking the first few bites of food during a meal. The pain can be described as intense, sharp, or like a muscle spasm. The pain is usually felt in the parotid (salivary gland) region, which is in the back of the mouth close to the ears, and is usually only felt on one side. The pain lessens with each bite of food but will return if there is a break in eating. First bite syndrome can start anywhere from days, to months, to years after treatment. This side effect can resolve on its own, but there are some treatments that can be helpful for this side effect.

nicotinic and muscarinic receptors are classified as

Answers

Nicotinic and muscarinic receptors are classified as cholinergic receptors.

A cholinergic receptor is an acceptor membrane protein for acetylcholine and its agonists.

Acetylcholine mediates neural transmission at the ganglionic synapse of both systems - sympathetic and parasympathetic.

They differ in nicotinic (inhibited by curare) and muscarinic (inhibited by atropine) receptors, the activation of which leads to different biological effects.

Therefore, we can conclude that acetylcholine acts through two types of cholinergic receptors: muscarinic and nicotinic.
