What advantage is the cell wall in relationship to osmotic pressure

A35-year-old woman comes to the ed complaining of chest pressure. she has had such episodes intermittently over the last 5 years, usually when sleeping, but over the last year she has had more frequent severe symptoms that are occasionally associated with severe migraine headaches. the pain is midsternal and is described as pressure that extends as a band around her chest. the ed physician is initially dubious that the pain is cardiac in origin, because the woman has no coronary disease risk factors. an ecg, however, shows 2mm st-segment elevation and inverted t waves in leads v1 through v5 and 1mm st-segment depression in leads ii, iii, and avf. before the cardiologist arrives in the ed, the patient's ecg has returned to normal. this repeat normal ecg is obtained after the administration of aspirin, nitroglycerin, morphine, and oxygen. which of the following is most likely for these findings? - diffuse intimal thickening with focal areas of atherosclerotic narrowing - intermittent thrombus formation and lysis in the left anterior descending artery - intermittent thrombus formation and lysis in the right coronary artery - plaque rupture and thrombus formation in the left anterior descending artery - transiently increased coronary vascular tone in the right coronary artery

The parents of a 9-year-old girl bring their daughter to the ed. for the last 12 hours, the child has suffered severe nausea and vomiting, as well as diarrhoea and abdominal cramps. further discussion with the child indicates that she suffers from blurred vision and headache. the parents originally were worried about bringing the child to the ed because they feared deportation since the family are illegal immigrants employed to pick strawberries on a nearby farm. on direct questionning, the parents admit that the child was assisting with spraying crops with pesticides the previous day. none of the family members was wearing any protecting clothing. her bp is 88/48 mmhg, pulse is 90/min, rr 33/min, temp 38 c. the child appears sweaty and confused. auscultation of the lungs reveals a diffuse wheeze bilaterally. pupils are miotic and the child has diffuse muscle weakness. which of the following interventions is the most appropriate treatment? - atropine- charcoal- glucagon- naloxone- exposure: consider organophosphate poisoning, which inhibits cholinesterase and results in accumulation of ach in both muscarinic and nicotinic sites. pralidoxime activates achatropine competes with ach only at muscarinic receptors, but will not reverse nicotinic effectscharcoal = gastric decontaminationglucagon = reverse beta-blocker overdosenaloxone = reverse effects of opioids
