Section 1: Anesthesia & Pharmacology
1. Which level of sedation is usually induced by the administration of an
anxiolytic agent?
• A. Moderate sedation
• B. Deep sedation
• C. Minimal sedation
• D. General anesthesia
Answer: C
Rationale: Minimal sedation (anxiolysis) is a drug-induced state during
which patients respond normally to verbal commands and maintain their
own airway. It is typically induced by low doses of anxiolytic agents to help
patients relax without compromising consciousness.
2. Using the ASA Physical Status Classification system, which patient would NOT
be appropriate for RN-administered moderate sedation?
• A. A healthy adult
• B. A well-controlled diabetic
• C. An asthma patient with no acute distress
• D. A patient with multiple system failure
Answer: D
Rationale: Patients with severe systemic disease that is a constant threat to
life (ASA PS IV) are not appropriate candidates for RN-administered
moderate sedation. This procedure should be performed under the direct
supervision of an anesthesia provider for such high-risk patients.
3. Which patient condition warrants an anesthesia consult?
, • A. Insulin-dependent diabetes
• B. Controlled hypertension
• C. Severe sleep apnea
• D. Latex allergy
Answer: C
Rationale: Severe sleep apnea poses significant risks for airway
management and respiratory depression during sedation. It requires
anesthesia consultation to ensure appropriate monitoring and airway
interventions are planned.
4. A patient who had a peripheral nerve block for an ankle ORIF would complain
of which symptom indicating potential local anesthetic systemic toxicity (LAST)?
• A. Headache
• B. Muscle weakness
• C. Metallic taste in mouth
• D. Nausea
Answer: C
Rationale: A metallic or "tinny" taste in the mouth, along with circumoral
numbness and tinnitus, are early signs of local anesthetic systemic toxicity
(LAST). These symptoms often precede more severe CNS and cardiovascular
effects.
5. Which depolarizing muscle relaxant is known to produce generalized
fasciculations?
• A. Rocuronium
• B. Succinylcholine
• C. Vecuronium
• D. Cisatracurium
Answer: B
Rationale: Succinylcholine is a depolarizing neuromuscular blocker. Its
mechanism of action involves initial stimulation of acetylcholine receptors,
, causing visible muscle fasciculations before paralysis ensues. Other listed
agents are non-depolarizing and do not cause fasciculations.
6. Which sedative is preferred for moderate sedation because of its short half-
life?
• A. Diazepam
• B. Valium
• C. Midazolam
• D. Morphine
Answer: C
Rationale: Midazolam is preferred due to its short half-life, making it easily
titratable with a faster onset and recovery time compared to longer-acting
benzodiazepines like diazepam.
7. What is the most common side effect of both benzodiazepines and opioids?
• A. Bradycardia
• B. Hypotension
• C. Respiratory depression
• D. Nausea
Answer: C
Rationale: Both classes of medications can cause respiratory depression. It
is the most common and significant side effect that requires vigilant
monitoring during procedural sedation.
8. Which medication is a known antagonist (reversal agent) for
benzodiazepines?
• A. Flumazenil
• B. Naloxone
• C. Buprenorphine
• D. Naltrexone
Answer: A
, Rationale: Flumazenil is a specific benzodiazepine antagonist that reverses
the sedative effects. Naloxone is the antagonist for opioids.
9. Which medication is a known opioid antagonist?
• A. Flumazenil
• B. Naloxone
• C. Midazolam
• D. Ketorolac
Answer: B
Rationale: Naloxone (Narcan) is a pure opioid antagonist that reverses the
effects of opioids, including respiratory depression and sedation.
10. A patient reports a latex allergy and carries an EpiPen. This indicates:
• A. A mild sensitivity
• B. Contact dermatitis
• C. A true latex allergy
• D. A non-allergic reaction
Answer: C
Rationale: A patient who carries an EpiPen for a latex allergy confirms a
true, potentially life-threatening allergy (Type I hypersensitivity). The
perioperative team must implement a latex-safe protocol.
Section 2: Positioning & Patient Safety
11. Positioning arms correctly to avoid pressure on the elbow helps prevent
injury to which nerve?
• A. Radial nerve
• B. Median nerve
• C. Ulnar nerve
• D. Musculocutaneous nerve
Answer: C
Rationale: The ulnar nerve runs in a groove at the elbow and is highly
