,1. Which of the following is the most critical step in preventing
infection during an invasive procedure?
a) Hand hygiene
b) Sterilization of instruments
c) Administering prophylactic antibiotics
d) Wound dressing
Correct ANS: a) Hand hygiene
Rationale: Proper hand hygiene is essential in minimizing the
risk of infection, as it significantly reduces the number of
pathogens transmitted during invasive procedures.
2. What is the most common complication associated with

a) Pneumothorax
b) Arterial puncture
c) Thrombosis
d) Infection

, Correct ANS: a) Pneumothorax
Rationale: Pneumothorax is a frequently encountered
complication due to the placement of a central venous catheter,
especially when inserting in the subclavian area.
3. In the context of a lumbar puncture, which landmark is used
for proper spinal needle insertion?
a) T12-L1 interspace
b) L2-L3 interspace
c) L3-L4 interspace
d) L5-S1 interspace
Correct ANS: c) L3-L4 interspace
Rationale: The L3-L4 interspace is chosen for lumbar

, d) X-ray
Correct ANS: c) Ultrasound
Rationale: Ultrasound is widely used due to its real-time
imaging capability, leading to a safer and more accurate
placement of needles in invasive procedures.
5. What is the primary purpose of performing an invasive
procedure such as thoracentesis?
a) To obtain tissue samples
b) To relieve symptoms
c) To visualize internal structures
d) To administer medications
Correct ANS: b) To relieve symptoms
