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?
a. Proliferative phase
b. Follicular phase
c. Secretory phase
d. Menstrual phase

Preoperative Diagnosis: Torn medial meniscus, left knee
Postoperative Diagnosis: Combination horizontal cleavage tear/flap tear, posterior horn, medial meniscus, left knee.
Operation: Arthroscopic subtotal medial meniscectomy, left knee
Anesthetic: General endotracheal
Description of Procedure: The patient was placed on the operating table in the supine position and general endotracheal anesthesia was administered. After an adequate level of anesthesia was achieved, the patient's left lower extremity was prepped with Betadine scrubbing solution, then draped in a sterile manner. Several sites were then infiltrated with 1% Xylocaine solution with Epinephrine to help control bleeding from stab wounds to be made at these sites. These stab wounds were made anterolaterally at the level of the superior pole of the patella for insertion of an irrigation catheter into the suprapatellar pouch area, anterolaterally at the level of the joint line for insertion of the scope and anteromedially at…
