Answer:
A urinary catheter
Explanation:
A urinary catheter is a tube that drains urine from the bladder. It is used in conditions such as incontinence, urinary retention or following a gynecologic surgery.
The urinary catheter, through the opening for the passage of urine called the <em>urethra</em>, is passed into the <em>bladder</em>. The catheter is connected to a bag that collects the urine. This bag could come in a small or a big size, depending on the purpose of usage and the time of the day being used.
The lack of control of urination, coupled with the fact that the client's rheumatoid arthritis makes it more difficult to move, makes an alternative means of passing urine important. The urinary bag does not require any form of movement to be functional therefore, with a urinary catheter and bag, the patient is stable and can effectively be given treatment to alleviate the pain and manage the incontinence.
Answer:
Mutualism
Commensalism
Parasitism
Explanation:
In mutualism, both organisms benefit.
<em>Ex</em>. Sea anemone and clownfish. Clownfish gives the anemone food, the anemone allows the clownfish to use it as a home.
In commensalism, one organism benefits, while the other is neither harmed nor benefited.
<em>Ex</em>. Sharks or whales and remora fish. The remora rides along the belly of whales or sharks and when it eats, the pieces that float around, the remora eats the excess.
In parasitism, one organism is benefited, while the other is hurt.
<em>Ex. </em>Dogs and fleas. The fleas are constantly biting and feeding off of the dog's skin. The dog gets bitten and itches a lot.
Mutualism and commensalism are similar because at least one organism is benefited.
Parasitism and commensalism are different because instead of one organism not getting hurt, like in commensalism, that happens in parasitism.
