,Q1. A 45-year-old female presents for nasolabial fold correction with a hyaluronic acid (HA)
filler. During the procedure, the patient reports immediate sharp pain and vision blurring in
the right eye. Which of the following is the MOST appropriate immediate intervention?
A. Apply warm compresses and administer oral antihistamines
B. Perform retrobulbar injection of hyaluronidase 1500 IU
C. Massage the area vigorously to disperse the filler
D. Administer topical brimonidine and monitor for 30 minutes
Correct Answer: B. Perform retrobulbar injection of hyaluronidase 1500 IU
Rationale: Immediate sharp pain and vision changes suggest intravascular injection causing
retinal artery occlusion. Retrobulbar injection of hyaluronidase is the standard of care to
dissolve HA and restore perfusion. Warm compresses and antihistamines are ineffective; massage
may propagate emboli; brimonidine is for erythema.
Why Wrong:
A - Warm compresses and antihistamines do not address vascular occlusion and delay
definitive treatment.
C - Vigorous massage can dislodge the embolus further and worsen ischemia.
D - Brimonidine is a vasoconstrictor for redness, not for vascular occlusion.

Management. Aesthetic Surgery Journal, 44(3), 245-256.
Q2. Which of the following best explains why high G' (elastic modulus) hyaluronic acid
fillers are preferred for deep supraperiosteal injections in the midface?
A. They have low water affinity, reducing post-injection edema
B. They provide greater lift and resistance to deformation under dynamic facial movement
C. They are more easily degraded by hyaluronidase if needed
D. They diffuse evenly through the tissue for a natural result
Correct Answer: B. They provide greater lift and resistance to deformation under dynamic
facial movement
Rationale: High G' fillers have higher elasticity, providing structural support and lift necessary
for deep placement over bone. They resist compressive and shear forces from facial muscles,
maintaining projection. Low G' fillers are softer and used for superficial lines. High G' fillers are
more resistant to hyaluronidase, not less. Diffusion is minimal for high G' fillers.
Why Wrong:
A - High G' fillers have similar water affinity; edema is not primarily related to G'.
C - High G' fillers are more cross-linked and thus more resistant to hyaluronidase
degradation.
D - High G' fillers are cohesive and do not diffuse; they remain localized.

, Q3. A patient with Fitzpatrick skin type V is being evaluated for laser hair removal. Which
of the following laser wavelengths and parameters is MOST appropriate to minimize the
risk of dyspigmentation?
A. Alexandrite 755 nm, fluence 30 J/cm², pulse duration 3 ms
B. Nd:YAG 1064 nm, fluence 40 J/cm², pulse duration 30 ms
C. Diode 810 nm, fluence 25 J/cm², pulse duration 5 ms
D. Ruby 694 nm, fluence 20 J/cm², pulse duration 2 ms
Correct Answer: B. Nd:YAG 1064 nm, fluence 40 J/cm², pulse duration 30 ms
Rationale: Longer wavelength Nd:YAG (1064 nm) has deeper penetration and less melanin
absorption, making it safer for dark skin. Longer pulse duration (30 ms) allows heat dissipation,
reducing epidermal damage. Alexandrite, diode, and ruby lasers have higher melanin absorption
and pose greater risk of burns and hyperpigmentation in skin type V.
Why Wrong:
A - Alexandrite 755 nm is strongly absorbed by melanin, increasing risk of epidermal injury
in dark skin.
C - Diode 810 nm has moderate melanin absorption; the short pulse duration (5 ms)
increases thermal damage.
D - Ruby 694 nm has the highest melanin absorption and is contraindicated in skin types
IV-VI.

Review. Lasers in Medical Science, 37(4), 2105-2115.
Q4. A 30-year-old patient with a history of cold sores requests a lip augmentation procedure
using a hyaluronic acid filler. Which of the following is the MOST appropriate prophylactic
management?
A. No prophylaxis; monitor for lesions post-procedure
B. Oral acyclovir 400 mg twice daily starting 24 hours before the procedure and continuing
for 3 days
C. Topical acyclovir cream applied to the lips immediately after injection
D. Oral valacyclovir 1 g daily for 7 days starting on the day of procedure
Correct Answer: B. Oral acyclovir 400 mg twice daily starting 24 hours before the
procedure and continuing for 3 days
Rationale: For patients with a history of herpes simplex labialis, prophylactic antiviral therapy is
recommended to prevent reactivation triggered by needle trauma. Acyclovir 400 mg BID starting
24 hours before and continuing for 3 days is a standard regimen. Valacyclovir 1 g daily is also
used but typically started 1-2 days prior; starting on the day of procedure is less effective. Topical
acyclovir is inadequate.
Why Wrong:
A - Without prophylaxis, the risk of herpes outbreak is significant, which can complicate
healing and cause discomfort.
C - Topical acyclovir has poor penetration and is insufficient for prophylaxis against
reactivation.
