Answer:
This is achieved because the sodium channels have a refractory period following activation, during which they cannot open again. This ensures that the action potential is propagated in a specific direction along the axon.
Respiratory depression
Respiratory depression is a complication of epidural anesthesia and should be closely monitored in laboring clients. A failed block, accidental intrathecal block, and a postdural headache are all side effects of a spinal epidural block
<h3>What is Epidural anesthesia ?</h3>
Epidural anesthesia is often used during labor and delivery, and surgery in the pelvis and legs. Epidural and spinal anesthesia are often used when:
- The procedure or labor is too painful without any pain medicine. The procedure is in the belly, legs, or feet
- If you choose to have an epidural, a physician anesthesiologist will insert a needle and a tiny tube, called a catheter, in the lower part of your back.

Ninety-one percent had been exposed to at least one trauma; 69 percent had been repeatedly exposed to trauma for longer periods of time. Only 7% acquired a PTSD diagnosis. The comorbidity of PTSD and other psychiatric diagnoses were 78%.
Explanation:
Red blood cells (erythrocytes)
The red blood cells are highly specialized, well adapted for their primary function of transporting oxygen from the lungs to all of the body tissues. Red cells are approximately 7.8 μm (1 μm = 0.000039 inch) in diameter and have the form of biconcave disks, a shape that provides a large surface-to-volume ratio. When fresh blood is examined with the microscope, red cells appear to be yellow-green disks with pale centres containing no visible internal structures. When blood is centrifuged to cause the cells to settle, the volume of packed red cells (hematocrit value) ranges between 42 and 54 percent of total volume in men and between 37 and 47 percent in women; values are somewhat lower in children. Normal red blood cells are fairly uniform in volume, so that the hematocrit value is determined largely by the number of red cells per unit of blood. The normal red cell count ranges between four million and six million per cubic millimetre.
Answer:
A. Only Paramedic
Explanation:
Basic training does not include obstetrics and intermediate is basic training with some field experience. Only paramedic training includes obstetrics training.
