Answer: E. exocytosis and it requires expenditure of ATP

Explanation:

Neurotransmitters are molecules released by synaptic pre-neurons and are the means of communication in a chemical synapse. They bind to neurotransmitter receptors and can attach to an ion channel (ionotropic receptors) or an intracellular signaling process (metabotropic receptors). Neurotransmitters are specific for the receptor they bind to and elicit a specific response in postsynaptic neurons, resulting in an excitatory or inhibitory signal. Because exocytosis is an example of active transport, it requires expenditure of ATP.

A 68-year-old female who was admitted with shortness of breath. On your arrival, the patient appears drowsy and is on 10L of oxy

zloy xaker [14]

Answer:

Arterial blood gas (ABG) results from a 68-year-old woman with difficulty breathing show:

Oxygenation (PaO₂): hypoxemia
pH: acidosis
PaCO₂: Hypercapnia
HCO₃⁻: normal

whose interpretation is: respiratory acidosis.

Hypercapnia can produce symptoms such as confusion, drowsiness or lethargy, headache, nausea and vomiting and, in severe states, can cause severe unconsciousness and coma.

Explanation:

Respiratory acidosis is due to a failure in the breathing process that produces hypoventilation, decreasing the partial pressure of oxygen (PaO₂) —hypoxemia— and increasing the partial pressure of CO₂ (PaCO₂), called hypercapnia.

Acidosis is the result of the accumulation of CO₂ in the body, which is reflected as a decrease in pH below 7.35, with no change in bicarbonate content.
Hypoxemia is the decrease of PaO₂ below 60 mmHg.
Hypercapnia is the increase of PaCO₂ in ABG above 45 mmHg.
Normal bicarbonate (HCO₃⁻) values range from 22 to 28 mEq/L in ABG. This compound can be altered in metabolic acidosis.

Hypercapnia mainly affects the nervous system, producing symptoms that alter the state of consciousness of the affected, also producing headache and even nausea and vomiting.

A patient was admitted to the burn unit the previous evening suffering from a severe burn involving his left upper extremity and

Ostrovityanka [42]

Any type of extreme stress can cause an increase in leukocyte count, leading in leukocytosis. A burn is more likely to stimulate leukocyte proliferation in order to fight infection, which is a concern when the skin's barrier function is compromised.

<h3>Wha is leukocytosis?</h3>

Leukocytosis means you have a high white blood cell count. This means you have more white blood cells than usual. Leukocytosis is a normal immune response and not always a cause for concern. Most of the time, this means your body is fighting an infection or inflammation.

Causes of leukocytosis -

neutrophils: inflammation and infection.

lymphocytosis: leukemia and viral infections.

monocytosis: cancer and other infections.

eosinophils: parasites and allergies.

What happens to the water soluble vitamins that you consume that exceeded your body's requirement? To the fat soluble vitamins t

liberstina [14]

Answer:

The water-soluble vitamins comprises all the 8 B vitamins and vitamin C. When one consumes these vitamins, they get dissolved in water and then get mediated to various parts of the body via bloodstream. The body utilizes the vitamins it requires, and then the extra vitamin if got consumed is eliminated from the body via urine.

As the water-soluble vitamins are excreted time to time, one requires to meet the needs for water-soluble vitamins each day. The fat-soluble vitamins are vitamins A, E, D and K. When one consumes fat-soluble vitamins, they get dissolved in fat prior to getting mediated via the bloodstream.

The body utilizes the required fat-soluble vitamins and then accumulates any extra vitamins in the liver. However, if one consumes huge concentrations of fat-soluble vitamins spontaneously, then one may develop a condition known as vitamin toxicity or hypervitaminosis. The condition can be chronic or acute.
