RNC-NIC PRACTICE EXAMINATION 2026
QUESTIONS WITH ANSWERS
GUARANTEED TO PASS.
■ Where should the left arm (LA) electrode be placed? Answer: Under
the left clavicle at the midclavicular line within the rib cage frame
corresponds to the left arm (LA) lead
■ Where should the left leg lead be placed? (LL). Answer: The left lower
abdomen within the rib cage frame is used for the left leg (LL) lead
■ What do precordial leads provide information about? Answer: In a
standard 12-lead ECG, precordial leads provide information about the
heart's electrical activity in the horizontal plane.
■ What does lead v6 help identify and where is it placed? Answer: Lead
V6 is placed horizontally in line with V5 at the left midaxillary line.
Accurate placement is essential for correct interpretation of ventricular
depolarization and detection of ventricular hypertrophy, ischemia, or
conduction abnormalities.
■ Function of the ductus arteriosus in a fetus? Answer: To provide an
opening to shunt blood from the pulmonary artery to the aorta
, ■ Which of the following findings in a 12 lead ecg is not indictive of
normal sinus rhythm. Answer: Normal QRS complex with a fixed and
regular R-R rhythm. Can indicate SVT
■ What is normal sinus rhythm defined by? Answer: a regular rhythm
with a ventricular rate within an age-specific normal interval (during the
first week post birth, the heart rate is approximately 120 beats/min)
a P-wave with constant morphology preceding every QRS complex
a P-wave that is positive in lead II (and also I and aVF)
■ Truncus Arteriosus. Answer: Truncus arteriosus is characterized by
one great (common) artery that stems from both the left and right
ventricles, overriding a ventricular septal defect/VSD
■ How long does the transient murmur of the ductus arteriosus closing
last in neonates? Answer: 48 hours.
■ In fetal circulation, blood from which of the following structures
enters the inferior vena cava? Answer: Ductus Venosus,
■ Fetal circulation relies on the _____ for gas exchange, postnatal
circulation uses _____ for gas exchange. Answer: placenta, lungs
