FREC 5 ADVANCED CLINICAL
PRACTICE EXAM QUESTIONS AND
ANSWERS
1. According to the 2023 ESC guidelines, what is the specific ST-segment elevation threshold
for a STEMI diagnosis in lead V2 or V3 for men under the age of 40?
A. Greater than or equal to 1.5mm
B. Greater than or equal to 2.5mm
C. Greater than or equal to 2.0mm
D. Greater than or equal to 1.0mm
Answer: B
Conceptual Explanation: For men under 40, the threshold for ST-elevation in leads V2-V3
is at least 2.5mm; for men over 40, it is 2.0mm, and for women, it is 1.5mm.
2. When performing needle chest decompression in a patient with a suspected tension
pneumothorax, what is the currently recommended anatomical site for adults?
A. 4th or 5th intercostal space, anterior axillary line
B. 2nd intercostal space, mid-clavicular line
C. 5th intercostal space, mid-axillary line
,D. 3rd intercostal space, mid-axillary line
Answer: A
Conceptual Explanation: Modern trauma guidelines (PHTLS/ATLS) now prefer the 4th or
5th intercostal space at the anterior axillary line over the 2nd intercostal space due to chest
wall thickness.
3. A patient presents with a MAP of 60 mmHg and an Intracranial Pressure (ICP) of 25 mmHg.
What is the calculated Cerebral Perfusion Pressure (CPP)?
A. 35 mmHg
B. 85 mmHg
C. 45 mmHg
D. 1.5 mmHg
Answer: A
Conceptual Explanation: CPP = MAP - ICP. In this case, 60 - 25 = 35 mmHg. A CPP below
50-60 mmHg is generally associated with poor outcomes in head injuries.
4. During capnography monitoring, a ‘Curare Cleft’ appearing in the alveolar plateau (Phase
III) typically indicates what clinical event?
A. Patient attempt to breathe against the ventilator or neuromuscular blockade wearing off
B. Esophageal intubation
C. A leak in the breathing circuit
, D. Rebreathing of carbon dioxide
Answer: A
Conceptual Explanation: The Curare Cleft is a dip in the Phase III plateau indicating that
the patient is making spontaneous respiratory efforts, often seen when muscle relaxants
are wearing off.
5. Which of the following describes the mechanism of action of Tranexamic Acid (TXA)?
A. It activates the intrinsic clotting pathway
B. It binds to calcium to prevent clot breakdown
C. It is a competitive inhibitor of plasminogen activation
D. It stimulates the release of von Willebrand factor
Answer: C
Conceptual Explanation: TXA is an antifibrinolytic that competitively inhibits the
activation of plasminogen to plasmin, thereby preventing the degradation of fibrin clots.
6. In the management of Eclampsia, what is the primary reason for administering Magnesium
Sulfate?
A. To lower the patient’s blood pressure significantly
B. To induce labor in a controlled manner
C. To reverse the effects of placental abruption
D. To prevent further seizure activity through CNS depression
