He is observed to be sitting up and struggling to breathe. His breathing is accompanied by use of accessory muscles, a weak cough, and audible wheezing sounds. His pulse is rapid and weak, and both heart and breath sounds are distant on auscultation. His parents relate that his asthma began to worsen after he developed a "cold," and now he doesn't get relief from his albuterol inhaler. Explain the changes in physiologic function underlying his signs and symptoms. Exam 5 - answer in most asthma patients the airway inflammation due to a cold virus causes epithelial injury. This severe airway inflammation means that the patient is probably suffering from bronchial hyper responsiveness, which causes airway obstruction and narrowing 23) oligodendrocytes produce myelin in the pns T/f - make true if false - answer false, oligodendrocytes produce myelin in the cns 24) someone in the early stages of alzheimer's disease requires assistance for their activities of daily living. T/f - make true if false - answer false, in the early stages of alzheimer's disease, individuals are still independent with their adls. 25) a 75-year-old male is brought to the emergency department via ambulance at 5 pm. The patient's spouse reports that when they woke up (approximately at 6 am) he reported to her that he was having some blurred vision but decided to go about his day. As the day progressed, he started experiencing tingling and feelings of weakness on the entire left side of his body. He has a past medical history of diabetes. Based upon these symptoms and past medical history, what do you suspect this patient is experiencing? How would you confirm this diagnosis? What treatment should be administered? Explain why you chose that treatment - answer patient was more than likely experiencing an ischemic stroke. A ct scan and mri will be ordered to determine if a blood clot was blocking blood flow and to rule out hemorrhagic stroke. If a clot is located and the patient is outside the 4 hour treatment window, a catheter based method to break the clot would be needed 26) risk factors for gallstone formation include each of the following except obesity male gender age (40's) pregnancy - answer male gender 27) risk factors for the development of peptic ulcer include each of the following except: pylori infection family history of pud nsaid use alcohol use stress - answer stress 28) what are rhythmic movements designed to propel the chyme along the small intestine toward the large intestine? - answer peristaltic movements 29) anti-diarrheal medication can be used with all types of diarrhea True or false - answer false 30) which of the following is characteristic of chronic transplant rejection? involves humoral immunity it responds well to immunosuppressive therapy involves increased t lymphocytes - answer involves humoral immunity 31) a patient is said to be in stage 2 kidney disease. What would you expect their gfr to be? A. 97 ml/min/1.73m2 B. 42 ml/min/1.73m2 C. 70 ml/min/1.73m2 D. 14 ml/min/1.73m2 - answer 70 ml/min/1.73m2 32) explain how the kidney can maintain a constant gfr despite variations in the arterial blood pressure of the rest of the body - answer the renal autoregulatory system causes the efferent arteriole to constrict leading to an increased resistance to outflow from the glomeruli with a subsequent increase in glomerular pressure and the gfr. When the afferent arteriole constricts there is a reduction in renal blood flow, glomerular pressure, and the gfr. 33) a patient presents in the emergency department with severe dehydration secondary to vomiting. The following are the results of their blood work: ph = 8.2, pco2 = 39 mm, and hco3 - = 33 meq/l. Based upon these results, what type of acid-base disorder are they experiencing? Is compensation occurring? Describe a treatment intervention for this disorder. Normal values are as follows: ph = 7.35-7.45, pco2 = 35-45 mm, hco3 - = 22-26 meq/l. - answer metabolic alkalosis. There is no respiratory compensation because the pco2 levels fall within normal range. Treatment is fluid replacement with normal saline solution 34) signs and symptoms of addison's disease include each of the following except: hyperpigmentation weight loss muscle weakness hyperglycemia - answer hyperglycemia 35) an endocrine hormone is released into circulation to act on a target organ True or false - answer true 36) hormones work through receptors, and the speed of this action varies. True or false - answer true 37) a 45-year-old woman presents with fatigue, weight gain, and cold intolerance. Lab findings show a low serum t4 and elevated tsh. 1.

(mark all that apply) 41) via the central haversian and volkmann canals an anastomosis between perforating and nutrient arteries diffusion through the endosteal surface of the bone and the canaliculi - answer all three 42) if someone loses their balance when walking on uneven terrain, explain how tendons and ligaments work to protect the joint and structures within it. - answer tendons and ligaments are in proprioception, meaning have awareness of one's position in space or movement of the body. When they undergo stretch, like walking on uneven terrain, the proprioception nerve fibers cause a reflex response to adjust the tension in the muscle. This will allow the body to maintain balance. The molecular structure of tendons and ligamants are of a collagen that contributes to high tensile strength. 43) a 72-year-old male is said to be in phase 3 of gout. He is obese and has a history of alcohol abuse. Develop a treatment plan including specific pharmacologic intervention and a nonpharmacologic recommendation to manage his disease - answer phase three gout is called inter-critical phase.

Lifestyle changes, such asweight loss, reduction in alcohol consumption, and avoid foods high in purines 44) a 72-year-old male is said to be in phase 2 of gout.
