Introduction
This comprehensive practice examination is meticulously designed to prepare
candidates for the rigorous National Board of Certification and Recertification for
Nurse Anesthetists (NBCRNA) certification exam. It assesses a broad spectrum of
knowledge, from foundational physiology and pharmacology to complex clinical
decision-making in perioperative settings. The exam employs multiple-choice and
scenario-based questions to evaluate the application of theoretical concepts, critical
thinking, and the ability to manage real-world anesthetic challenges. Emphasis is
placed on regulatory compliance, patient safety, and adherence to the highest
professional and ethical standards, ensuring the candidate is fully prepared for both
the examination and a successful career.
,SECTION ONE: QUESTIONS 1–50
1. A patient with a known history of malignant hyperthermia (MH) is scheduled
for a procedure requiring general anesthesia. Which of the following is the
most appropriate initial step in the perioperative management?
A. Premedicate with dantrolene 2.5 mg/kg IV 30 minutes prior to induction.
B. Ensure a fully functional MH cart is immediately available in the operating
room.
C. Use a low-flow anesthesia circuit to minimize volatile agent exposure.
D. Maintain the patient on a propofol infusion for the duration of the procedure.
🟢 Correct Answer: B. Ensure a fully functional MH cart is immediately available in
the operating room.
🔴 Explanation: While all options are relevant to MH management, the most
critical initial step is ensuring the immediate availability of a fully stocked MH cart,
including dantrolene, prior to the induction of anesthesia. The cart must be ready
to treat a crisis immediately. Dantrolene prophylaxis is no longer routinely
recommended.
2. The pressure-volume loop of a patient receiving mechanical ventilation in
the ICU demonstrates a downward shift of the inspiratory curve, indicating
decreased lung compliance. Which of the following clinical scenarios is the
most likely cause?
A. Obstructive sleep apnea
B. Atelectasis
C. Bronchospasm
D. Pneumothorax
🟢 Correct Answer: B. Atelectasis
,🔴 Explanation: Atelectasis leads to a loss of lung volume and increased stiffness,
resulting in decreased compliance. This is visually represented on a pressure-
volume loop as a downward and rightward shift of the inspiratory limb. Options
A, C, and D are more commonly associated with increased resistance
(bronchospasm) or shifts that affect the overall volume capacity.
3. A patient is scheduled for an elective cholecystectomy and is currently taking
a monoamine oxidase inhibitor (MAOI) for depression. A safe preoperative
washout period for MAOIs before anesthesia is generally considered to be:
A. 24-48 hours.
B. 72 hours.
C. 1-2 weeks.
D. 1 month.
🟢 Correct Answer: C. 1-2 weeks.
🔴 Explanation: MAOIs can cause profound hypotension and potentially fatal
hypertensive crises when combined with anesthetic agents. A washout period of
1-2 weeks is recommended to allow for the regeneration of monoamine oxidase
enzymes and reduce the risk of these interactions. Shorter periods are generally
considered inadequate.
4. Which of the following changes in the fetal circulation is a primary goal of
administering tocolytics to a parturient in preterm labor?
A. Increasing fetal heart rate variability
B. Decreasing maternal cardiac output to the placenta
C. Reducing uterine activity and contractions
D. Promoting fetal lung maturity
🟢 Correct Answer: C. Reducing uterine activity and contractions
, 🔴 Explanation: Tocolytics are specifically administered to inhibit uterine
contractions and delay preterm birth. This provides time for the administration of
corticosteroids to accelerate fetal lung maturity and, when appropriate, arrange
maternal transport to a facility with a higher level of neonatal care. The other
options describe different maternal/fetal therapeutic goals.
5. During a pre-anesthetic evaluation, a patient reports a history of "bad
reactions" to local anesthetics. The most effective method to differentiate
between a true allergy and a vasovagal reaction is:
A. Premedication with diphenhydramine.
B. Performing a skin test with the local anesthetic.
C. A detailed history of the specific reaction.
D. Using an alternative local anesthetic from a different class.
🟢 Correct Answer: C. A detailed history of the specific reaction.
🔴 Explanation: A thorough, focused history is the single most effective way to
differentiate between a true IgE-mediated allergy and other adverse reactions like
vasovagal episodes, toxicity, or psychogenic responses. While skin testing and
other methods can be used, they are not as diagnostically valuable as a
comprehensive history.
6. The theoretical minimal alveolar concentration (MAC) of an anesthetic agent
is defined as:
A. The concentration required to prevent autonomic response to a surgical
stimulus.
B. The concentration that produces surgical immobility in 50% of patients.
C. The concentration that produces anesthesia in 95% of patients.
D. The maximum concentration safe for administration without causing apnea.
