Answer:
A. During general anesthesia drugs are administered to provide hypnosis, ensure analgesia, and skeletal muscle relaxation. The degree of relaxation is assessed by supramaximal train-of-four stimulation of the ulnar nerve and measuring the electromyogram response of the adductor pollicis muscle.
B. ACh is hydrolyzed by the enzyme acetylcholinesterase, which is on the postsynaptic membrane, with its active site facing the synaptic cleft. Succinylcholine acts as a depolarizing agent that prevents repolarization of the nerve. Therefore, no further ACh is released until the drug is cleared. Name another site within the neuromuscular junction that might be affected to prevent muscle contraction. (Hint: curare acts by this mechanism.) Curare competes with ACh for the receptor proteins on the muscle cell membrane, thus reducing the size of the end-plate potential. Thus, curare can be used as a muscle relaxant during anesthesia.
C.Thus, curare can be used as a muscle relaxant during anesthesia.
Explanation:
The normal sequence of events initiates with the beginning of an action potential by the motor nerve. Due to this, depolarization and calcium ion release. The mechanism of actin and myosin leads to sarcomere shortening.
What do you mean by Depolarization?Depolarization may be defined as a state in which the cell's internal charge becomes less negative and more positive with respect to the outside.
A drug Botulinum toxin prevents acetylcholine (ACh) from accumulating in the neuromuscular junction and causing a sustained contraction in a normal individual.
Curare is a non-depolarizing neuromuscular blocking agent. The nerve axon is the name of another site within the neuromuscular junction that might be affected to prevent muscle contraction.
Therefore, it is well described above.

Why is MRSA difficult to treat
Answer:
MRSA infections are more difficult to treat than ordinary staph infections. This is because the strains of staph known as MRSA do not respond well to many common antibiotics used to kill bacteria. ... Given enough time, bacteria can change so that these antibiotics no longer work well.
Explanation:
1. Compare and contrast airborne transmission and droplet transmission.
in 4 sentences!!
2.How are transmission-based precautions different from standard precautions?
Answer:
Airborne transmission is when germs float through the air after a person talks, coughs, or sneezes. Droplet transmission is when germs travel inside droplets that are coughed or sneezed from a sick person enters the eyes, nose, or mouth of another person. Both can contaminate someone when it gets in a persons eyes, nose, or mouth. But only droplets stick to surfaces and can infect someone who touches the same surface.

why do people respond in different ways to the same kind of pain
Explanation:
watch the sonic movie YOU NEED TO SEE IT he reason why some people are more sensitive than others comes down to how our body modulates pain from the skin to the brain and the structure of the brain itself. It all begins with a bunch of sensory receptors detecting an unpleasant stimuli. These are transformed into pain signals that are then conducted throughout the central nervous system via a series of 'pain pathways'.

Nurses at a local hospital recently conducted a survey of patients about their expectations of nurses. Which of the following was NOT an opinion shared by the majority of responding patients?
a. Seventy-three percent thought nurses should keep their hair tied back and off their shoulders.
b.Ninety-one percent thought that nurses should not have long fingernails.
c. Eighty-eight percent thought nurses should spend less time at the nurse's station.
d. Fifty-five percent thought it difficult to distinguish a nurse from other medical staff in the hospital.
Final answer:
The opinion not held by the majority of the survey's respondents was that it is difficult to distinguish a nurse from other medical staff, as it was just over half at 55%, making it significantly lower than the other options.
Explanation:
The opinion NOT shared by the majority of responding patients in the nurse survey was d. Fifty-five percent thought it difficult to distinguish a nurse from other medical staff in the hospital. A majority is typically considered to be more than 50%, however, in the context of survey opinions, a dominant majority is often implied to mean a significantly larger percentage agree on an aspect. Since option d is barely over half and significantly lower than the other percentages mentioned, it makes it the least agreed upon statement and not considered a majority opinion similar to the others with much higher percentages.

The dental assistant had a 3/4 bottle of disinfectant and a 1/3 bottle of another cleaning solution. How much solution does the dental assistant have?
1 1/12
Explanation:You add both fractions together to find how much solution he has in total.
To find the total amount of solution, add the fractions 3/4 and 1/3. The dental assistant has a total of 1 and 1/12 of solution.
Explanation:To find the total amount of solution the dental assistant has, we need to add the amounts of the two bottles. The dental assistant has a 3/4 bottle of disinfectant and a 1/3 bottle of another cleaning solution. To add these fractions, we need to find a common denominator. The least common multiple of 4 and 3 is 12, so we can rewrite 3/4 as 9/12 and 1/3 as 4/12. Adding these fractions gives us a total of 13/12 or 1 and 1/12.
