Chapter 27, Problem 6CCS
23-Year-Old Female with Menstrual Irregularity
Jasmine Herrera, 23, has been referred to the endocrinology clinic. She is very overweight, with obvious acne and facial hair. She complains of irregular menstrual cycles. “My husband and I want to use the rhythm method," she says, “but I don’t have any rhythm!”
6. NCLEX-STYLE Jasmine is started on oral contraceptives containing a combination of an estrogen and progesterone. These will regulate her menstrual cycles and decrease her androgen level. They will also act to prevent pregnancy by preventing ovulation. What phase of the uterine cycle is caused by sustained elevation of both estrogen and progesterone levels?

b. Follicular phase
c. Secretory phase
d. Menstrual phase

10. Your instructor will give you 2 amino acids during the activity session (video 2-7.
A. First color all the polar and non-polar covalent bonds in the R groups of your 2 amino acids
using the same colors as in #7. Do not color the bonds in the backbone of each amino acid.
B. Next, color where all the hydrogen bonds, hydrophobic interactions and ionic bonds could
occur in the R group of each amino acid. Use the same colors as in #7. Do not color the bonds
in the backbone of each amino acid.
C. Position the two amino acids on the page below in an orientation where the two R groups
could bond together. Once you are satisfied, staple or tape the amino acids in place and label
the bond that you formed between the two R groups.
- Polar covalent Bond - Red
- Non polar Covalent boND- yellow
- Ionic BonD - PINK
Hydrogen Bonn - Purple
Hydrophobic interaction-green

Find the dental formula and enter it in the following format:
I3/3 C1/1 P4/4 M2/3 = 42 (this is not the correct number, just the correct format)
Please be aware: the upper jaw is intact (all teeth are present). The bottom jaw/mandible is not intact. The front teeth should include 6 total rectangular teeth (3 on each side) and 2 total large triangular teeth (1 on each side).
12. Calculate the area of a circle which has a radius of 1200 μm. Give your answer in mm² in
scientific notation with the correct number of significant figures.
