Question 1

A 45-year-old patient requires ultrasound-guided drainage of a pelvic abscess. Which anatomical landmark is most important to identify to avoid injury during needle placement?

Accepted Answer

The iliac vessels

Answer

The iliac vessels run adjacent to pelvic structures and must be identified and avoided during any pelvic interventional procedure to prevent vascular injury.

Question 2

Which quality assurance step should a sonographer perform before beginning an ultrasound-guided procedure to ensure accurate needle visualization?

Accepted Answer

Test needle visualization using a phantom or water bath

Answer

Testing needle visualization in a phantom or water bath confirms proper beam alignment and needle echogenicity before patient use.

Question 3

A post-transplant kidney patient presents for routine surveillance ultrasound. Which finding requires urgent reporting to the transplant team?

Accepted Answer

Absent diastolic flow on Doppler interrogation of the renal artery

Answer

Absent or reversed diastolic flow in a transplant kidney indicates high resistance and may signal acute rejection or vascular compromise requiring urgent intervention.

Question 4

In managing a pediatric patient scheduled for an abdominal ultrasound, which preparation guideline differs most significantly from adult protocols?

Accepted Answer

Shorter fasting periods adjusted by age and weight

Answer

Pediatric fasting guidelines are age- and weight-dependent because prolonged fasting poses greater risk of hypoglycemia in children.

Question 5

During ultrasound-guided amniocentesis, the sonographer's primary role is to:

Accepted Answer

Continuously monitor needle tip position and fetal heart rate

Answer

The sonographer provides real-time imaging guidance, continuously tracking the needle tip and monitoring fetal heart rate throughout the procedure.
