OMSA Exam Review 2026/2027: 100%
Verified Questions & Answers |
Guaranteed Grade A
SECTION 1 – Medication Safety Principles & Error Prevention (Q1-20)
Question 1
The “Six Rights” of medication administration now include a seventh right in the 2026 AAOMS
guidelines. What is it?
A. Right documentation
B. Right reason
C. Right to refuse
D. Right response
Answer: B – Right reason
Rationale: AAOMS/DAANCE 2026 added “Right Reason” to ensure the indication matches the
order (prevents wrong-drug errors in oral surgery where multiple similar-sounding narcotics are
used).
Question 2
A high-alert medication in OMS includes:
A. Ibuprofen 800 mg
B. Ketamine IV
C. Amoxicillin 2 g
D. Lidocaine 2% with epi
Answer: B – Ketamine IV
Rationale: ISMP/AAOMS 2026 high-alert list for ambulatory surgery: opioids, ketamine, propofol,
and local anesthetic systemic toxicity (LAST) agents require independent double-check.
Question 3
The most common cause of wrong-dose errors in oral surgery offices is:
A. Look-alike/sound-alike drugs (LASA)
, B. Illegible handwriting
C. Decimal point errors
D. Lack of patient identifiers
Answer: A – Look-alike/sound-alike drugs (LASA)
Rationale: Common LASA pairs: hydrocodone/oxycodone, hydromorphone/morphine,
lidocaine/Marcaine (AAOMS Safety Toolkit 2026).
Question 4
A patient is allergic to penicillin. The surgeon orders “Cephalexin 500 mg”. Your immediate
action:
A. Administer – cephalosporins are safe
B. Clarify order – cross-reactivity risk ~2–8%
C. Give and monitor
D. Substitute clindamycin without asking
Answer: B
Rationale: True anaphylactic penicillin allergy → avoid 1st/2nd gen cephalosporins (AAOMS
Antibiotic Prophylaxis Guideline 2026).
Question 5 (SATA)
“Never events” in OMS medication safety include:
A. Wrong-site surgery
B. Administering neuromuscular blockers without ventilation
C. Opioid overdose without naloxone available
D. Retained surgical items
E. All of the above
Answer: E
Rationale: CMS/AAOMS Never Events list includes medication-related deaths/disabilities.
SECTION 2 – Controlled Substances Handling (Q6-15)
Question 6
Schedule II medications in the OMS office must be stored:
A. In a locked cabinet with single lock
B. In a securely locked, substantially constructed cabinet (double-locked preferred)
