You are called to the home of a 12-year-old female with a chief complaint of shortness of breath. You find no evidence of trauma. She complains of numbness & tingling of the lips and dizziness. Vitals are BP 116/80, P 120 and strong, R 32 and regular, and SpO2 of 99%. Skin signs are warm, flush, and dry. For this patient, you would:

Using the Rule of Nines, what is the Percent Body Surface Area burned? An ADULT has burns to the front of both legs and the front of both arms

You are called to the home of a 70-year-old male whom you find in bed, pulseless and apneic. The correct first steps in treating this patient would be to:

Prereq check: another u-sub example and reversing the power rule.  Remember we often need to reverse the power rule when integrating, so for example we should rewrite the following as a power function:

Concept check: do this after taking notes on 1.1 One of the simplest differential equations is: . A solution to this would be a function y so that the derivative of y equals y. Of course works. But we also saw that also works for any constant C, giving the general solution to the DE because it gives all solutions as you vary over all C values. Let’s change the equation a bit: what is the general solution to: ?

Select the shortest bond in the following group

In which set are all three species isoelectronic?
