Question 15: Calcium hydroxylapatite (CaHA/Radiesse) injections carry elevated risk in the glabellar and periorbital regions primarily because:

CaHA migrates more readily than HA in highly mobile facial zones
CaHA causes a stronger inflammatory reaction in thin-skinned areas
CaHA particles are too large to pass through facial vessels in any region
CaHA is irreversible and cannot be dissolved, making vascular occlusion near ophthalmic vessels untreatable (Correct answer)

Correct answer: CaHA is irreversible and cannot be dissolved, making vascular occlusion near ophthalmic vessels untreatable

Because CaHA has no enzymatic reversal agent, vascular occlusion near vessels supplying the eye (e.g., supratrochlear, supraorbital) can lead to irreversible vision loss.

Question 16: Which product is used to reverse the effects of hyaluronic acid fillers?

Botulinum antidote
Saline solution
Lidocaine
Hyaluronidase (Correct answer)

Correct answer: Hyaluronidase

Hyaluronidase is an enzyme that breaks down hyaluronic acid, allowing correction of overfilling or complications.

Question 17: What is the primary mechanism of action of botulinum toxin type A in aesthetic treatments?

Inhibits norepinephrine uptake at nerve terminals
Blocks acetylcholine release at the neuromuscular junction (Correct answer)
Stimulates acetylcholine release at the neuromuscular junction
Promotes collagen synthesis in the dermis

Correct answer: Blocks acetylcholine release at the neuromuscular junction

Botulinum toxin type A cleaves SNAP-25 protein, preventing acetylcholine vesicle fusion and release at the neuromuscular junction, resulting in temporary muscle paralysis.

Question 18: A patient develops localized necrosis on the nasal tip following filler injection. Which anatomical vessel was most likely compromised?

Facial artery
Dorsal nasal artery (Correct answer)
Angular artery
Infraorbital artery

Correct answer: Dorsal nasal artery

The dorsal nasal artery supplies the nasal tip and is a high-risk vessel for occlusion during nasal filler injections, leading to tip necrosis.

Ongoing competency assessments verify that aesthetic nurses keep pace with evolving techniques, products, and safety protocols, directly supporting patient safety outcomes.

Question 20: Which muscle is primarily responsible for frown lines between the eyebrows?

Frontalis
Zygomaticus major
Corrugator supercilii (Correct answer)
Orbicularis oculi

Correct answer: Corrugator supercilii

The corrugator supercilii muscle contracts to draw the eyebrows downward and together, creating glabellar lines.

Question 21: Which energy-based treatment is best suited for improving skin texture and stimulating collagen?

Cryotherapy
Microdermabrasion
Radiofrequency treatment (Correct answer)
Laser tattoo removal

Correct answer: Radiofrequency treatment

Radiofrequency devices deliver heat to the dermis, which stimulates collagen production and improves skin texture.

Question 22: When managing a patient with post-procedural hyperpigmentation after laser treatment, which risk factor should have been identified in the pre-treatment assessment?

Recent haircut
Fitzpatrick skin types IV–VI or recent sun exposure (Correct answer)

Question 25: Regarding informed consent for aesthetic procedures, which statement BEST reflects legal and ethical standards?

Informed consent obtained one week prior is automatically invalid and must be re-obtained
A signed consent form alone constitutes legally adequate informed consent
Informed consent is a process that includes discussion of risks, benefits, alternatives, and questions answered before the patient signs (Correct answer)
Verbal consent witnessed by a staff member is always legally sufficient for invasive procedures

Correct answer: Informed consent is a process that includes discussion of risks, benefits, alternatives, and questions answered before the patient signs

Informed consent is a dynamic communication process—not merely a document—that requires meaningful discussion of risks, benefits, and alternatives before the patient voluntarily agrees.

Question 26: Which federal law requires aesthetic practices that are covered entities to have a Notice of Privacy Practices (NPP) available to patients?

The Stark Law
The Anti-Kickback Statute
HIPAA Privacy Rule (Correct answer)
The False Claims Act

Correct answer: HIPAA Privacy Rule

The HIPAA Privacy Rule mandates that covered entities provide patients with a Notice of Privacy Practices describing how their PHI may be used and disclosed.
