Pediatric ARDMS Exam & Practice Exam 2026-2028 | 200
Questions with Correct Answers & Detailed Rationales |
Pediatric Sonography Exam Prep | PDF
Introduction
Prepare for the Pediatric ARDMS examination with this comprehensive 200-question Pediatric
Sonography Practice Exam designed to strengthen your knowledge, improve test-taking
confidence, and reinforce high-yield pediatric ultrasound concepts.
This practice resource covers essential areas commonly encountered in pediatric sonography,
including neonatal cranial ultrasound, pediatric abdominal imaging, pyloric stenosis,
intussusception, renal and urinary tract pathology, pediatric scrotal ultrasound, hip
dysplasia, neonatal spine, thyroid and neck imaging, vascular studies, pediatric cardiac
ultrasound, gastrointestinal disorders, ultrasound physics, Doppler principles, artifacts,
instrumentation, and patient safety.
Each question includes the correct answer and a concise rationale to help you understand the
underlying concept rather than simply memorize answers. The questions are organized in an
exam-style format to support focused studying, self-assessment, and final review.
1. Which ultrasound transducer is generally preferred for imaging the neonatal brain
through the anterior fontanelle?
A. High-frequency linear
B. Curvilinear abdominal
C. Phased-array cardiac
D. Endocavitary
Answer: A. High-frequency linear
Rationale: A high-frequency transducer provides excellent spatial resolution for superficial
neonatal brain structures through the fontanelle.
,2. The anterior fontanelle provides the primary acoustic window for which pediatric
ultrasound examination?
A. Renal ultrasound
B. Cranial ultrasound
C. Scrotal ultrasound
D. Thyroid ultrasound
Answer: B. Cranial ultrasound
Rationale: The anterior fontanelle is commonly used as an acoustic window for neonatal
cranial sonography.
3. Which finding is most characteristic of germinal matrix hemorrhage in a premature
infant?
A. Hemorrhage confined to the cerebellum
B. Echogenic material in the caudothalamic groove
C. Enlarged fourth ventricle only
D. Absence of the corpus callosum
Answer: B. Echogenic material in the caudothalamic groove
Rationale: Germinal matrix hemorrhage commonly begins near the caudothalamic groove
because the germinal matrix is highly vascular and fragile in premature infants.
,4. Which ventricular structure is normally evaluated carefully during neonatal cranial
sonography?
A. Lateral ventricle
B. Gallbladder
C. Renal pelvis
D. Common bile duct
Answer: A. Lateral ventricle
Rationale: The lateral ventricles are routinely assessed for dilation, hemorrhage, and other
abnormalities.
5. A premature neonate has echogenic material within the lateral ventricles. Which
condition should be suspected?
A. Hydrocele
B. Intraventricular hemorrhage
C. Pyloric stenosis
D. Hydronephrosis
Answer: B. Intraventricular hemorrhage
Rationale: Intraventricular blood can appear echogenic within the ventricular system.
6. Which sonographic finding is most consistent with hydrocephalus?
, A. Decreased ventricular size
B. Enlarged cerebral ventricles
C. Thickened pyloric muscle
D. Enlarged renal cortex
Answer: B. Enlarged cerebral ventricles
Rationale: Hydrocephalus involves abnormal accumulation of cerebrospinal fluid and
ventricular enlargement.
7. Which structure connects the lateral ventricles with the third ventricle?
A. Foramen of Monro
B. Aqueduct of Sylvius
C. Foramen magnum
D. Central canal
Answer: A. Foramen of Monro
Rationale: The paired foramina of Monro connect each lateral ventricle to the third ventricle.
8. The cerebral aqueduct connects the:
A. Lateral and third ventricles
B. Third and fourth ventricles
C. Fourth ventricle and lateral ventricles
D. Third ventricle and central canal only
