Local anesthetics inhibit nerve conduction in a reversible manner without altering the nerve. The inhibition appears rapidly and for a longer or shorter duration depending on the products and the concentrations used. The extent of the territory rendered insensitive to pain depends on the modes of administration of the local anesthetic, either at the level of the nerve endings, or at the level of a nervous trunk, for example.
They act at the level of the neuronal membrane by interfering with the process of excitation and conduction. The anesthetic crosses the axon membrane, rich in lipids, in the form of base before taking up a cationic form on the internal face of the neuron where the pH is more acidic.
At this level, there is a blockage of nerve conduction by decreasing the membrane permeability to sodium ions that occurs during the depolarization phase. As the progression of the anesthetic action along the nerve increases, the threshold of excitability increases and the conduction time increases. This is completely blocked from a certain concentration of local anesthetic.
The nerve fibers are unequally sensitive to the action of local anesthetics: they disappear in order: the painful, thermal, tactile sensations.

Answer:
The answer is: letter d, Explain the defect and show the baby to the parents as soon as possible.
Explanation:
"Birth defects" are also known as "congenital anomalies." When a baby is born with an anomaly,<u> it is best to tell the parents by explaining the defect and showing the baby to them as soon as possible. </u>Telling the parents will <em>allow them to acknowledge their emotions</em> and <em>lessen anxiety.</em> It is also important for them to see the baby so they are assured of the baby's safety. In this case, it will allow them to stay calm while asking support from friends or asking an advice from the physician.
Thus, this explains the answer.
