Why is there a difference in the heat budget at various latitudes despite the Earth as a whole having a
balanced heat budget? What happens at polar and tropical latitudes? What will be an ideal response?
ANS:Answer
should include:
? The heat budget varies with latitude because the sun hits latitudes at different angles
which then alters the distribution area of that solar radiation.
? Polar latitudes receive the sun's radiation from a very low angle. Although the amount of
radiation from the sun is constant, the distribution of that radiation spreads over a larger
area. Also, the radiation must travel through more of the atmosphere before reaching the
surface of the Earth. These factors contribute to a high level of reflection of light energy
in these regions.
? Tropical latitudes receive the sun's radiation from a nearly vertical angle. The same
amount of solar energy being projected to the poles is concentrated into a smaller area.
There is less atmosphere to travel through and minimal reflection.
? There is more solar energy received in tropical latitudes than polar latitudes

You are dispatched to a residence for an "ill person." Upon arrival, you enter the residence and find the patient, a 72-year-old woman, lying on the couch; she is responsive to pain only. Her son, who arrived shortly before you, tells you that her air conditioner went out, and that he came over to her house to pick her up and found her in her present condition. He further tells you that his mother has diabetes, hypertension, and congestive heart failure. Assessment of the patient reveals that her skin is flushed, hot, and dry; her pulse is rapid and weak; and her blood pressure is low. After moving the patient to the ambulance and applying high-flow oxygen, you should next:
A) remove any bulky clothing, assess her temperature, begin active cooling if her temperature is greater than 105°F, and start a large-bore IV with normal saline. B) intubate her to protect her airway, apply chemical ice packs to her trunk area only, start an IV and give a normal saline bolus, and assess her axillary temperature. C) cover her with sheets that are soaked with water, start a large-bore IV and give a 20-mL/kg fluid bolus, and administer 50% dextrose for presumed hypoglycemia. D) strip her to her underclothing, begin rapid cooling measures, assess her rectal temperature if possible, establish vascular access, and assess her blood glucose level.
