Jennifer was running an 8K cross-country race. This race was the last of her high school career. She was on pace to set a new re

cord. She started climbing the last hill, knowing just over the hill was the finish line. As she came over the hill three deer suddenly plowed through the runners, Jennifer was hit. She was thrown into the air upon impact by one of the deer. Jennifer was sitting on the ground, dazed and slumped to one side. Emergency Medical Technicians (EMTS) and an athletic trainer surrounded Jennifer. Jennifer's breathing was labored. EMT's noted Jennifer's wet gasping sounds with grunts of pain. A cervical collar was quickly placed on Jennifer and she was strapped to a backboard and transported to the nearest hospital.
Upon arriving at the hospital Jennifer's vital signs were BP 100/80, Pulse 108 and Respirations 23 breaths per minute. The doctors ordered x-rays of the chest. While waiting for X-rays, the Dr. Smith could see Jennifer was in pain. As Dr. Smith examined Jennifer he noticed bruising was forming on the lateral chest wall, just below the inferior tip of her scapula. There was a 2 inch laceration the extended deeply into her skin. The EMT's placed an adhesive seal over the wound before transporting her to the hospital. As Dr. Smith removed the adhesive seal, there was a gurgling, sucking sound each time Jennifer inhaled, and a small amount of blood foamed at the edges of the wound. Dr. Smith probed the wound and Jennifer screamed.

When the adhesive seal was removed, why did Dr. Smith hear a sucking sound each time Jennifer inhaled? What can you conclude about the pressure gradient between the atmosphere and the pleural cavity?

Answer:

Pneumothorax = Negative, Possible Lung Laceration

Explanation:

If the sucking sound is coming then it means that the lung is totally punctured and it like a major hull breach for the lung. The sucking sound has confirmed that the there is no pneumothorax possible.

The negative pressure gradient of lung is neutralized due to the laceration and the sucking sound can be heard due to the lung tendency toward inner flow and natural gradient maintenance. The hear beat is pumped to 108 to consume as much as possible amount of oxygen from one working lung to maintain the body's oxygen levels. These types of cases require immediate medical attention.

Recovery from a severe metabolic acidosis is most dependent on which of the following?
Svet_ta [14]

Answer:

The best answer to the question: Recovery from a severe metabolic acidosis is most dependent on which of the following? would be, D: Arterial pH.

Explanation:

When a person reaches such a severe situation, as having metabolic acidosis, then it means that his body systems are not being able to use the mechanisms to restore the normal acid-base balance within it. Normally, a person needs to have an acid-base balance of 7.35 to 7.45. Drops below or above these numbers will result in acidosis or alkalosis and in severe problems. The way that the body can tell if there is something going on with the pH levels in the blood is through a series of chemoreceptors, especially in the neck, that constantly measures the amount of CO2 molecules in the blood and especially, the pH (acidity or alkalinity) given by the excessive presence, or absence, of acids in the blood. There is another ration that is important for the body, and it is the presence of bicarbonate ions, which will help balance out the amount of H+ ions produced by normal cell function, or increased cell function. In metabolic acidosis, the amount of H+ vs. bicarbonate ions is immense, H+ winning by far over bicarnonate, and a series of steps are taken by the body to restore the 20:1 ratio, and especially return the pH to its normal range. All mechanisms point towards that one measure: pH. Once the level of pH has been reached, we can tell a person is finally coming out of metabolic, or recovering from, metabolic acidosis.

In what ways are the rational explanations of doctors related to folk explanations concerning the pu properties of some foods?
Monica [59]

Answer:

The rational explanations of doctors related to folk explanations concerning the properties of some foods began in the early days of ancient civilizations, when medicine was not yet a definable subject and folk explanations were the only ones who brought knowledge to bear on the field of health, and "try, taste and wait for the end of the process", was the only way to find out the food´s properties.

Explanation:

The ancient Greeks civilization, seeking for logic got curious about folk´s  explanations about existence and the whies paving the road for important developments the rational explanations in medicine and the relationship with food propierties.

The set up medical schools leaving the informatily of folk explanations hidden in the darkness, to open a path to the scientific observations of patients who were sick, although many of them were philosophers, they investigated on nutrition as possoble causes for illness, even though many folk traditions already practiced on certain foods to get healthier or to get health maintenance.

Doctor´s observations on folks´ remedies like using olive oil to increase temperature in the body, were the base for them to develop techniques, which could become sophisticated medicine procedures.

This theory remained popular in Western Europe until the 17th century. However, while the ancient Greeks pushed medicine forward in many ways, the theory of humors posed an obstacle to advances in medical practice.  But many of the folk´s natural remedies are similar to some home remedies practiced today.

Folks´ natural cures have doctors become herbalists treatment specialist, turning natural remedies into rational treatments using foods as the barley soup plus vinegar and honey to cough up phlegms; purging a person with food laxatives, diuretics or emetics to restore body´s balance; taking celery, to relieve inflamation; and in general rationalizing the concept of eating healthy foods, so the basis of modern medicine comes from the folk´s knowledge on food properties.

The antibiotic bacitracin binds to bactoprenol after it inserts a
laila [671]

Bactoprenol is indeed a peptidoglycan transporters that cycles monomers and places them somewhere at cell wall's growth point.

As bacitracin binds to this bactoprenol, the orientation of the peptidoglycan to the cell membrane fluidizes, allowing potassium ions to move from the protoplasts.

As a result of interfering with cell wall production and changing membrane potential, the bacterial cell is lysed.
