How many kcal did you consume during 24 hours ? how many kcal did your body burn during the same period ? assuming that these values are typical for you, and that your metabolism runs at a constant rate, what is the difference between your intake of kcal and the kcal required (muscular activities + basal metabolism)? (use negative numbers if your metabolism consumes more than you took in) if this discrepancy were repeated daily for five years (1826 days), how many surplus (deficit) kcal would you have eaten? considering that one pound (454 g) of fat contains 4,090 kcal, how many pounds of weight gain (loss) could this discrepancy translate into? fat our diets should provide less than 30% of the total calories needed in the form of fat. how many grams of fat did you consume? since fat contains 9 kcal/gram, how many calories of fat did you consume? how many total kcal did you consume? what percentage of your kcal were derived from fat? is this value within the recommended dietary limits for fat? what foods were the major source of fat in your diet?

Name three bad things that can happen to a teenager who has no refusal skills and no self-control:

Which of the following represents the results of a review of well-controlled studies of vitamin c supplementation on the resistance to, and recovery from, colds? there was a reduction in the duration of colds by 50% on the average. there was a slight effect on reducing the duration and severity of colds for people taking vitamin c supplements. there was a significant reduction in the duration of colds in people who consumed at least one gram a day. there was a significant reduction in the number of colds only in people who consumed > three grams per day.

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
