Answer:
SARS- CoV- 2 is a virus that infects human by the oral-respiratory way in which the virus enters the body and these viruses have spikes on their surface made of spike proteins that allow these viruses to bind with the infected cell.
The infected cells have ACE2 receptor that is protein present on the surface of the human cells. Binding allows the structural change in the virus to fuse and enter in the cell where viruses reproduce them selves with the cell with cell system.
The reasons why 241am smoke detectors are perfectly safe is because;
(i) The amount of americium is very little.
(ii) The aluminium core is where the detector is hosted.
(iii) The detector has a plastic cover.
(iv) Radiation is limited in penetrating power.
(v) There is a low number which is leaving the case.
(iv) ions get trapped by electrodes.
I believe the correct answer is B)
Answer:
The nervous system
Explanation:
The nervous system comprises the central nervous system, consisting of the brain and spinal cord, and the peripheral nervous system, consisting of the cranial, spinal, and peripheral nerves, together with their motor and sensory endings.
The answer is a neurologic
assessment by the stroke team should be performed within 25 minutes of
arrival. Neurologic assessment is the examination of sensory neuron and motor
responses, especially reflexes, to know whether the nervous system is compromised.
The following actions are undertaken:
<span>- </span>Review the patient's history, including past
medical history.
<span>- </span>Perform a physical exam.
<span>- </span>Begin last known well if not already done.
<span>- </span>Execute a neurological exam to assess patient's
status using the NIHSS or the Canadian Neurological Scale.
<span>-
</span><span>The CT scan should
be accomplished within 25 minutes from the patient's arrival in the Emergency Depatment
and should be read within 45 minutes.</span>
