Welcome to the 171th FOAMed Quiz.
Question 1
Your 10 year old male patient presents with unilateral scrotal pain for 26 hours. He denies trauma and fever, but he vomited a couple of times.
You suspect testicular torsion.
Which of the following statements is true regarding diagnosis and management of this patient?
A: Emergent surgical exploration is not indicated, for the testicle will not survive after 24 hours anyway
B: Presence of flow on doppler ultrasound excludes testicular torsion
C: If manual detorsion is successful, your patient can be discharged and required outpatient follow up in 1 week
D: When treated promptly by surgical exploration, the chance of survival of the testicle is still about 7 percent
The correct answer is D.
Testicular torsion was covered on RebelEM last week.
A systematic review demonstrates a 7.4 percent survival rate between 24 and 48 hours.
Presence of flow on doppler ultrasound does not reliably exclude testicular torsion.
Regardless of the success of manual detorsion, all patients will require surgical evaluation.

Question 2
Your 87 year old patient presents with a femoral neck fracture. She is in severe pain and you decide to perform an ultrasound guided nerve block.
In which of the following blocks, the local anesthetic should be injected deep to the psoas tendon?
A: Fascia Iliaca Compartment Block (FICB)
B: Femoral nerve block (FNB)
C: Pericapsular Nerve Group (PENG) block
The correct answer is C.
EMDOcs covered nerve blocks in hip fractures last week.
There are 3 nerves that innervate the proximal femur. These are the femoral nerve, the obturator nerve and the accessory obturator nerve. The PENG block is thought to target these three nerves best. When performing a PENG block, the local anesthetic should be injected deep to the psoas tendon.

Question 3
Your patient presents with severe vulvar pain and she notices a swelling near her vagina.
In what location would you expect to find a Bartholin’s abscess in regard to the vaginal opening?
A: At 12 o’clock
B: At 2 o’clock
C: At 4 o’clock
D: At 6 o’clock
The correct answer is C.
Bartholin’s abscess was covered on EM@3AM last week.
Bartholin’s glands are pea-sized and located bilaterally at the 4 o’clock and 8 o’clock positions of the introitus.

Question 4
A woman with suspected ovarian torsion presents to your ED.
Which of the following statements is true about ovarian torsion?
A: Ovarian torsion affects women below 50 years of age only
B: Most patients have a cyst or mass >5 cm
C: The majority of patients present with fever
D: Nausea and vomiting is rare in patients wth ovarian torsion
The correct answer is B.
Ovarian torsion was covered on emDOCs last week.

Most patients have a cyst or mass >5 cm.
Nausea and vomiting is present in 70% of patients.
Up to 20% of patients presents with fever.
