During your assessment of a 2 week old baby, you notice flaring of his nostrils, abdominal respirations with increased heart rate while crying and a breathing rate of 90 breaths per minute. Which of these findings should be of concern?

In order to determine which of these findings are of concern we must know what are normal findings in a 2 week old. The normal respiratory rate of a 2 week old is up to 60 breaths per minute. 90 breaths is much more than what should be found and along with the nostril flaring suggests breathing difficulties. Babies tend to be belly breathers so abdominal respirations and increased heart rate while crying are normal findings.

A computer store gives a 15% discount to students. On Black Friday an additional 25% is taken off the discounted price. Lila, a student at the local high school, purchases a Chromebook for $589 on Black Friday. How much did it originally cost?

First we must determine how much of a discount was applied. 15% plus 25% is equal to 40%. Lila received a total of 40% off the original cost. To determine what the original cost is we must set up the equation 589 + 0.40x = x where X is the original cost. Subtract 0.40 x from both sides to have X on the side by itself and our equation becomes 0.60 x = 589. Divide both sides by 0.60 and we get x = 981.67.

Why do I have a belly button?

Everyone has a belly button. As babies we grow inside of our mother by attaching to her uterine wall. The umbilical cord connects from our abdomen to the placenta which is attached to the uterine wall. This is how we receive all of the required nutrients and oxygen required to live and grow. When a baby is born the placenta starts to deteriorate as it is no longer needed. When the umbilical cord is cut because we can now live on our own outside of our mother's body, it heals and what is left becomes our belly button.
