Answer: a. too much acetylcholine staying in the neuromuscular junction for too long

Explanation:

Sarin is a gaseous organophosphate. This gas is used for chemical warfare. This affects the nervous system of the body. The gas if inhaled can cause death within minutes.

Acetylcholine is a neurotransmitter molecule. It is released from the pre-synaptic neurons that binds to the acetylcholine receptors.

The gas sarin will target the enzyme acetylcholinesterase present in the neuromuscular junction of the body where the nerves actually meet the muscles. The enzyme degrades nerve signaling molecule acetylcholine. Thus when the sarin degrades the enzyme the levels of acetylcholine will rise up in the blood. The acetylcholine remain in the neuromuscular junction. The acetylcholine will stimulate the nerve cell receptors. Excess of acetylcholine will cause excessive twitching and may lead to paralysis.

The statement would that the nurse would utilize is that it allows the patient to breathe on his own while he can receive a preset number of breaths from the ventilator.

He/she can breathe as much or as little as he wants beyond what the ventilator will breathe for him.

SIMV stands for synchronized intermittent mandatory ventilation.

can say a more of control form of ventilation.

With the help of SIMV, we set the rate, set either volume or pressure, and add in pressure support.

The role of SIMV is that it provides additional inspiratory pressure which doesn't let the patient work hard and also enable better oxygenation and a speedy recovery.

using SIMV is not a piece of cake, this can be a challenge to understand, as it is usually a combination of control, assisted and spontaneous breaths and to check it requires skills.

The stress-relaxation effect occurs in all blood vessels but is most important in the arteries.
boyakko [2]

Answer:

The best answer to the question: The stress-relaxation effect occurs in all blood vessels but is most important in the arteries, would be, B: False.

Explanation:

The reason for this being the correct answer comes from the function that both arteries and other blood vessels play and the significance of the process of stress-relaxation to the functionality of oxygenation, blood flow and pressure.

Stress-relaxation is the process by which the pressure within a specific tissue, in this case the blood vessels, does not increase as the volume of blood increases. Now, because arteries´ main job is not merely to conduct oxygenated blood from the heart towards the tissues of the body, it requires the presence not just of volume, but also of pressure, and usually, pressure in arteries is higher than the actual volume of blood. This is possible because of the high content of muscular tissue present in the middle layer of arteries. Without this high pressure, exchanges would not be possible. But veins, whose main purpose is to return all the de-oxygenated blood from the tissues to the heart, have the need to become reservoirs of large volumes of blood, and therefore have what is known as a high level of compliance (their muscular layer is not as powerful as that of arteries and the elastic tissues are more prominent, allowing the vessel to contain larger volumes of blood, but exert much lesser pressure). It is these blood vessels, veins, who show a high level of stress-relaxation, contain volume without affecting pressure, and not arteries, and that is why the answer is false.

A carrier that transmit a disease
AnnyKZ [126]

Answer:

An asymptomatic carrier

Explanation:

An asymptomatic carrier (healthy carrier or just carrier) is a person or other organism that has become infected with a pathogen, but that displays no signs or symptoms.

Although unaffected by the pathogen, carriers can transmit it to others or develop symptoms in later stages of the disease. Asymptomatic carriers play a critical role in the transmission of common infectious diseases such as typhoid, C. difficile, influenzas, and HIV. While the mechanism of disease-carrying is still unknown, researchers have made progress towards understanding how certain pathogens can remain dormant in a human for a period of time. A better understanding of asymptomatic disease carriers is crucial to the fields of medicine and public health as they work towards mitigating the spread of common infectious diseases.

The nurse is reviewing the laboratory test results of several children who have come to the clinic for evaluation Child A with a total cholesterol of 150 mg/dL and low-density lipoprotein

<h3>What is lipoprotein?</h3>

A lipoprotein is a biochemical assemblage whose main job is to move fat molecules in water that are hydrophobic, such as in blood plasma or other extracellular fluids. They have a phospholipid outer shell enclosing a triglyceride and cholesterol center, with the hydrophilic regions pointing outward toward the surrounding water and the lipophilic portions pointing inward toward the lipid center. The complex is stabilized and given a functional identity by an uncommon protein called apolipoprotein, which is embedded in the outer shell. This identity helps to define the complex's function.

Lipoproteins include several enzymes, transporters, structural proteins, adhesins, antigens, and toxins. Plasma lipoprotein particles are an example (HDL, LDL, IDL, VLDL and chylomicrons). These plasma particle subgroups act as the main initiators or regulators of atherosclerosis.
