After a pap screening, colposcopy, and biopsy, she is diagnosed with advanced cervical carcinoma. Which of the following group of lymph nodes will this carcinoma first metastasize to?
-
Deep inguinal nodes
-
Internal & external iliac nodes
-
Superficial inguinal nodes
-
Para-Aortic nodes
-

A 34-year-old victim of a rollover motor vehicle accident is taken to emergency surgery for internal bleeding. The surgeon is forced to ligate the internal iliac artery to control the hemorrhage. Which correct anastomosis will provide collateral circulation to pelvic structures during the procedure?
-
Middle Rectal A./Inferior Rectal A
-
Internal Pudendal A./Lumbar Aa.
-
Inferior Gluteal A./Deep Artery of the Thigh
-
Iliolumbar A./Inferior Gluteal A.
Correct Answer
A. Inferior Gluteal A./Deep Artery of the ThighExplanation
The inferior gluteal artery (internal iliac) and the deep artery of the thigh (external iliac/femoral A.) anastomose around the ischium to provide collateral circulation to pelvic structures. The other three anastomoses you should be aware of in this area are Lumbar/Iliolumbar, Median Sacral/Lateral Sacral and Superior Rectal/Middle Rectal Arteries. The other three answer choices are not actual anastomoses.Rate this question:

A 29-year-old female presents to the clinic with pain during defecation. Ultrasound reveals a large amount of fluid in the pouch of Douglas, presumably due to an infection. Which identifies the correct procedure and landmark for this patient's treatment?
-
Culdocentesis/Posterior Fornix of the Vagina
-
Culdoscopy/Anterior Fornix of the Vagina
-
Paracentesis/Pubic Symphysis
-
Cystoscopy/Anterior Fornix of the Vagina
Correct Answer
A. Culdocentesis/Posterior Fornix of the VaginaExplanation
Culdocentesis is the medical procedure of draining fluid from the rectouterine pouch or pouch of Douglas. The physician will enter the pouch through the posterior fornix of the vagina and remove the fluid accumulating there. (B) Culdoscopy refers to an investigation of the rectouterine pouch by the camera and is performed through the posterior fornix of the vagina. (C) Paracentesis refers to drainage of fluid from the abdominal cavity. It is typically performed through the linea alba in the midline of the abdomen or laterally, just above the iliac fossae. (D) Cystoscopy refers to the camera investigation of the bladder either by a transurethral or suprapubic method.Rate this question:

A 4-year-old male is brought to the pediatrician after biting the lateral, posterior surface of his tongue. The physician can see a lesion developing but sends the boy home without treatment. Which will be true of subsequent infection of his injury?
-
Will drain unilaterally to submental lymph nodes
-
Will drain bilaterally to submandibular lymph nodes
-
Will drain first to preauricular lymph nodes
-
Will drain eventually to jugulo-digastric lymph nodes
Correct Answer
A. Will drain eventually to jugulo-digastric lymph nodesExplanation
The lateral surface of the tongue (with exception of the tip) will drain first to submandibular lymph nodes, unilaterally. In addition, as you travel more posteriorly along the tongue, the more superior the lymph drainage. When this infection reaches deep cervical lymph nodes, it will most likely empty into jugulo-digastric (aka upper deep cervical) lymph nodes. Conversely, if the infection was more anterior on the tongue, it would most likely drain to the lower deep cervical lymph nodes or jugular-omohyoid. (A,B,C) The lateral portions of the tongue drain unilaterally to submandibular lymph nodes. Preauricular nodes will drain external ear structures, scalp and parts of the eyelid. Submental nodes drain the tip of the tongue.Rate this question:

The umbilical artery that is obliterated in the adult and is a branch off the Internal iliac artery anterior to the bladder vessels is called?
-
Median umbilical artery
-
Median umbilical ligament
-
Medial umbilical artery
-
Medial umbilical ligament
-
Median iliac ligament
Correct Answer
A. Medial umbilical ligamentExplanation
The correct answer is "Medial umbilical ligament." In the adult, the umbilical artery becomes obliterated and forms a fibrous cord called the medial umbilical ligament. It is a branch off the internal iliac artery and is located anterior to the bladder vessels. The median umbilical artery is a different structure that is present during fetal development but typically obliterates completely before birth. The median iliac ligament is not related to the umbilical artery.Rate this question:

A 65-year-old male patient complains of urinary problems. On physical exam, you feel an enlarged prostate, and suspect Benign Prostatic Hyperplasia, which part of his urinary urethra could be constricted?
-
Preprostatic
-
Prostatic
-
Intermediate
-
Spongy
-
Bulbous
Correct Answer
A. PreprostaticExplanation
Prostatic urethra travels through the prostate gland. So, if the periurethral zone of the prostate hypertrophied, the nearby prostatic urethra would be occluded.Rate this question:

During your OBGYN rotation, a patient asks you for a caudal epidural block, which nerves will NOT be blocked?
-
Pelvic splanchnics
-
Sacral splanchnics
-
Pudendal
-
S2 dorsal root
-
S2 ventral primary ramus
Correct Answer
A. Sacral splanchnicsExplanation
These nerves come from the sacral splanchnic ganglia, off the sympathetic trunk. The sacral splanchnic nerves contribute to the inferior hypogastric plexus and provide sympathetic innervation to the vascular smooth muscle of the pelvic viscera.Rate this question:

During surgery in the pelvic region, the attending surgeon decides to ligate the internal iliac artery. She turns to the resident intern and asks him for the various collateral circulation patterns of the pelvic neurovascular. Which of the following collateral circulations should the intern eliminate from his responses since it will not work to continue providing blood supply to the pelvic region?
-
Superior gluteal and inferior gluteal arteries
-
Middle rectal and superior rectal arteries
-
Lateral sacral and median sacral arteries
-
Inferior gluteal and deep artery of the thigh
-
Iliolumbar and lumbar arteries
Correct Answer
A. Superior gluteal and inferior gluteal arteriesExplanation
The superior gluteal and inferior gluteal arteries both come off the internal iliac artery, the posterior and anterior division respectively, so they will not serve as a collateral circulation.Rate this question:
