The skyrocketing prices of fuel and food were threatening to bankrupt the Johnson families small farm, which was no match or the multi-million-dollar mega-farms that had been popping up all over the southeast. Joseph, the family patriarch, was especially troubled by the farm’s financial circumstances. He knew that this year’s corn crop was his best chance to save the farm, and his distress was evident to his family as they sat around the dinner table. “Michael, I’m going to need your help tomorrow,” Joseph said to his eldest son. L have to go into town to pick up a part for the combine so I can fix it before it’s time to harvest in a few months. I need you to spread the potash and phosphate on the corn cause we’re expecting some rain by the end of the week. ” Michael, his mouth full of fried chicken, nodded in agreement. He wasn’t all that interested in farming, which over the years had been a point of contention between him and his father. At the moment Michael was thinking more about the time he’d be missing with his friends, but he also realized how vital this chore was to his father and the farm. I’ll do it right after school, Dad,” he replied. The following afternoon, Michael was loading heavy bags of fertilizer into the drop spreader on the farm tractor. His father’s cheerless emperor the previous evening weighed heavily on him. Michael knew that 25 bags of the potassium and phosphorous-based fertilizer was the normal load to cover the 40 acres of corn the family had planted that spring. But as he was emptying the 25th bag into the spreader, an idea flashed through his mind: “If we need a good corn crop to make it, maybe I should add a little extra fertilizer. Michael decided that some extra fertilizer couldn’t hurt, so he quickly loaded 1 5 extra bags. He was certain that adding the extra fertilizer would produce a massive crop when it came time to arrives in a few months. Michael hadn’t told his father about the extra fertilizer he’d added to the corn, wanting to see his father’s surprise over the size of the harvest in a few months. As expected, the rain started Friday afternoon; Michael was certain it would start an incredible growth spurt in the newly fertilized, young corn plants and that his family would hit pay dirt in a few months.
He was out of bed early on Saturday morning, taking his four-wheeler down to the cornfields. He expected to see a vibrant green sea of young corn, extra healthy due to the fertilizer “boost” he had even them. His stomach dropped a bit as he stared out at a field of sickly looking corn plants, their leaves pale green and slightly wilting. “Maybe it rained too hard and that beat the plants up a little,” thought Michael, trying to be optimistic. “I’ll check on them again in a few days. I’m sure they’ll have perked up by then! The next few days didn’t bring the results Michael was hoping for. The corn plants looked even worse! I en leaves were Declining to yellow slantingly Ana were controlling to Walt Having watched his father grow corn for most of his 14 years, Michael knew this crop isn’t going to make it. A lump was forming in his throat as he made his way back to the house, not sure how to tell his father about the corn. Questions 1. What sort of environment (hypotonic, hypersonic, isotonic) did the extra fertilizer create around the roots of the corn? 2.
Keeping in mind your answer to the previous question, what do you believe caused the corn plants to wilt and eventually die? 3. If Michaels mistake had been caught earlier, is there anything that could have been done to prevent the corn from dying? 4. Generally, people water their lands with 100% H2O??no solutes added. What sort of environment does this create around the roots of the plant? Part II??Too Little, Too Late Meanwhile, elsewhere in Haberdasher County, Tom was feeling slightly nervous as he exited the staff lounge and entered the hustle and bustle of County Hospital’s ERR to begin his first shift as an URN.
The first few hours of his shift passed slowly as Tom mostly checked vital signs and listened to patients complain about various aches, pains, coughs, and sniffles. He realized that the attending physician, Dry. Greene, who as rather “old school” in general about how he interacted with nursing staff, wanted to start him out slowly. Tom knew, though, that the paramedics could bring in a trauma patient at any time. After his lunch break, Tom didn’t have long to wait before the paramedics burst in through the swinging double-doors of the ambulance bay wheeling in a young man on a gurney.
Edward, a veteran MET, recited the vital signs to Tom and Dry. Greene as they helped push the gurney into the trauma room, “18- year-old male, SSW to the right abdomen, heart rate 92, respiratory rate 22, blood erasure 95/65, no loss of consciousness. ” A gunshot wound! Tom knew that gunshot wounds were sometimes the most difficult traumas to handle. Once inside the trauma room, Dry. Greene began his initial assessment of the patient while Tom got busy organizing the things he knew would be needed. He attached a pulse-ox monitor to the patient’s index finger so Dry.
Greene could keep an eye on the 02 levels in the patient’s blood and he inserted a Foley catheter so the patient’s urine output could be monitored. After finishing his initial duties, Tom heard Dry. Greene saying, “It looks like the bullet missed the liver and kidney, but it may have severed an artery. That’s probably why his BP is a bit low. Tom, grab a liter of saline and start a fast IV drip we need to increase his blood volume. ” Tom grabbed one of the fluid-filled bags from the nearby shelf, attached a 12-gauge IV needle to the plastic tubing, and gently slipped the needle into the patient’s intellectual vein.
He then hung the plastic bag on the IV stand and let the fluid quickly start to flow down the tubing and into the patient’s vein. The reaction was quick and violent. The patient’s heart rate began to skyrocket and Tom heard Dry. Greene shouting, “His 02 saturation is falling! Pulse is quickening! What is going on with this guy?! ” Tom stood frozen in place by the fear. He heard Dry. Greene continuing, “Flailing! We’ve lost a pulse Tom, get the crash cart, we need to shock this guy to get his heart going again! ” Tom broke free from his initial shock and did as Dry. Greene had ordered. He then started CPRM as Dry.
Greene readied the cardiac defibrillator to shock the patient. They continued to alternate between CPRM and defibrillator for almost an hour, but to no avail. As Dry. Greene announced ten time AT eaten , loom Tell a slackening Telling In ten plot AT Nils stomach. He couldn’t believe that he had lost his first trauma patient! Then Tom noticed that the fluid in the Foley catheter bag was bright red. “Dry. Greene, there’s hemoglobin in the Foley bag,” he said. “How could that be? ” responded Dry. Greene. Tom began to trace back over his steps in the trauma, trying to think of anything that could have caused the hemoglobin’s.
His mounting fear turned to outright terror as he looked at the now empty bag on the IV stand. Its label didn’t read “Saline,” but rather “Distilled Water. ” He looked at Dry. Greene, his heart quickly sinking, and said, “I think I may have killed the patient. ” Questions 1. What problem did the distilled water in the patient’s bloodstream create? 2. What heaped to the patient’s blood cells as a result? 3. Considering the function of red blood cells, why did the patient’s oxygen levels fall? 4. After Tom made his error, is there anything that could have been done to save the patient’s life?
