Question 1
During a simulated central venous catheter insertion workshop, a
nursing student must identify critical landmarks to avoid
complications. Which anatomical structure, if inadvertently
punctured, poses the greatest risk of causing a pneumothorax
during the subclavian approach?
A. Internal jugular vein
B. Subclavian artery
C. Apex of the lung (cupola)
D. Clavicle

, Correct ANS: C
Rationale: In the subclavian approach, the lung apex (cupola)
lies immediately beneath the clavicle. Accidental puncture of this
structure can lead to a pneumothorax. Recognizing and avoiding
the lung apex is a key safety step in the procedure.

Question 2
In a hands‑on airway management simulation, a student is
required to perform an emergency cricothyrotomy. Which
anatomical landmark is used as the superior border when
identifying the cricothyroid membrane?
A. Cricoid cartilage
B. Thyroid cartilage
C. Hyoid bone
D. Epiglottis
Correct ANS: B
Rationale: The cricothyroid membrane is located between the
thyroid cartilage (superiorly) and the cricoid cartilage (inferiorly).
Accurate identification of the thyroid cartilage is essential to
locate the correct incision site during an emergency
cricothyrotomy.

Question 3
During a simulation focused on managing cardiac arrhythmias, a
nursing student is asked to identify the primary blood supply to
the sinoatrial (SA) node. In the majority of the population, which
artery supplies the SA node?
A. Left anterior descending (LAD) artery
B. Right coronary artery (RCA)
C. Left circumflex artery
D. Posterior descending artery
Correct ANS: B
Rationale: In approximately 60–70% of individuals, the
sinoatrial node is supplied by the right coronary artery. This
anatomical fact is crucial for understanding arrhythmogenic
conditions and for planning interventional procedures involving
cardiac conduction.

Question 4
©2025
, During a neurological intervention simulation, a student must
accurately locate the central sulcus on a brain model. Which of
the following best describes the anatomical relationship of the
central sulcus?
A. It separates the precentral (motor) gyrus from the postcentral
(sensory) gyrus.
B. It divides the frontal lobe from the parietal lobe along its
anterior border.
C. It marks the inferior boundary of the occipital lobe.
D. It separates the cerebrum from the cerebellum.
Correct ANS: A
Rationale: The central sulcus is the prominent groove that
separates the precentral gyrus (primary motor cortex) from the
postcentral gyrus (primary somatosensory cortex). Recognizing
this relationship is essential for intervention skills that rely on
precise neurological assessments.

Question 5
In a respiratory emergency simulation, a nursing student is
practicing endotracheal intubation. Which anatomical structure
must be directly visualized to confirm that the endotracheal tube
is correctly placed in the trachea?
