If a woman with vaginal bleeding reports syncope, the EMT should assume that she "is in shock".
<u>Option: B</u>
<u>Explanation:</u>
The most common form of syncope is the Vasovagal syncope. It is triggered by a dramatic drop in blood pressure, resulting in a decline in blood flow to the brain. When one stand up, gravity causes blood to settle down below one's diaphragm, in the bottom part of their body.
It is a component of a wider class of medical conditions which may lead in TLOC involving postural orthostatic tachycardia syndrome (POTS), orthostatic hypotension and neurologically mediated syncope (NMS). The overlapping of such clinical symptoms causes confusion about the category of syncopes which may complicate assessment approaches and present difficulties for diagnosis and treatment, especially in young women.
A reverse reaction is the chemical reaction moving both forward and backwards.
An example of this is Ammonium chloride ⇌ ammonia + hydrogen chloride
This is a symbol for reverse reaction ⇌
Answer: They all survive in any environment.
Explanation: Protists have the ability to survive in any environment, even extreme environment. They can live in the ocean, desert or extremely hot environment, or even a extremely cold environment.
I'll explain why the others aren't correct.
Protists can be both unicellular and multicellular, they're not always unicellular. Kingdom Protista contains all eukaryotics, so they're not always unicelluar.
Protist cannot make or consume food. Animals consume food, and plants make food, not protista. Yes they're many plant-like protists out there, such as algae, they get their food from the sun above. So all protists cannot make or consume food.
Protist does have flagella, but not all protists. Protists that are motile and generate movement have flagella, meaning they move. Not all protist move, like plants can't move. So, not all protists have flagella, meaning they can move.
Let me know if you have any questions.
