The chronological order of events starting from poisoning should be as follows:
- Ricin enters the victim's body
- Ricin is absorbed into the blood and enters the cells
- Ricin binds to ribosomes in the cytoplasm
- Ricin inactivates 28s rRNA in the large subunits of the ribosomes
- Ribosomes are unable to add new amino acids to polypeptides
- Protein synthesis halts in many tissues
- Multiple organ systems fail
- The victim dies
Ricin is a plant toxin. It is poisonous to mammalian cells as it interferes with the catalytic activity of ribosomes in protein synthesis. It irreversibly binds to the ribosomal subunits and halts the polypeptide synthesis process, leading to cell death.
Note: Your question is incomplete, but probably it includes the following options:
a. Ricin is absorbed into the blood and enters the cells
b. Ricin inactivates 28s rRNA in the large subunits of the ribosomes
c. Ricin binds to ribosomes in the cytoplasm
d. Ricin enters the victim's body
e. Multiple organ systems fail
f. Protein synthesis halts in many tissues
g. The victim dies
h. Ribosomes are unable to add new amino acids to polypeptides

Answer:
This is because it helps our bones to contract
Explanation:
Answer:
The correct option is : c. subdural space-contains cerebrospinal fluid
Explanation:
The meninges are the protective membranes covering spinal cord and the brain. The meninges is composed of three membrane layers- dura mater, arachnoid mater, pia mater.
Dura mater is the thick durable outermost membrane of the meninges.
Arachnoid mater: It is the middle layer, present between the dura mater and the pia mater. It has a fine spider web-like appearance and thus it is named after the Greek word Arachne, meaning spider.
The pia mater or pia: It is a very thin and delicate innermost layer, which is present on the surface of the brain. The pia mater is loosely connected to arachnoid layer and is fused or firmly bound to the surface of the brain.
The space between arachnoid mater and pia is known as the subarachnoid space. This space is filled with the cerebrospinal fluid.
Therefore, subdural space-contains cerebrospinal fluid is incorrect and thus not the correct match.
Answer:
Because patient involvement in their care and patient choice are critical aspects of providing care, I would choose the shared decision-making model, or SDM model, in this scenario. The steps of this model are (1) explain the choice, (2) describe the options, and (3) help the patient weigh the options and make a choice. Before meeting with Ms. Bennett, I would research to gather information on different care options, such as full-time placement in a skilled nursing facility until Ms. Bennett is able to perform all ADLs, a full-time in-home aide who would provide assistance with ADLs until Ms. Bennett fully recovers, and a part-time respite worker who would provide assistance with ADLs to Ms. Bennett in her home during the hours when Ms. Bennett's family members and friends can't provide this care. I would gather information regarding the length of recovery to determine the cost of each option. I would then meet with Ms. Bennett to determine her wishes regarding remaining in her own home versus placement in a skilled nursing facility. I would then discuss the benefits and drawbacks of each option in terms of level of care provided and cost. I would involve other members of the multidisciplinary team, such as social services, to determine which options Ms. Bennett's insurance would cover and how much Ms. Bennett would have to pay for each option. I would ask Ms. Bennett about family and friends and their willingness and ability to provide assistance. I would then help Ms. Bennett weigh the options and make a choice regarding her post-discharge plans for care.
