INTRODUCTION
,This comprehensive examination is designed to assess the knowledge, clinical judgment, and decision-making skills
essential for safe and effective nurse anesthesia practice. The questions encompass foundational scientific principles,
applied pharmacology, advanced monitoring, and complex clinical scenarios encountered in perioperative and critical
care settings. A significant emphasis is placed on integrating theoretical knowledge with practical application,
regulatory compliance, and ethical standards. The multiple-choice format includes scenario-based questions that
require critical thinking, prioritization, and the application of evidence-based guidelines. This assessment is structured
to evaluate readiness for professional certification and to reinforce the highest standards of patient care and safety in
the field of nurse anesthesia.
SECTION ONE: QUESTIONS 1 – 100
1. A 45-year-old patient with a history of hypertension and type 2 diabetes is scheduled for an emergency
appendectomy. The patient's blood pressure is 160/95 mmHg, and heart rate is 105 bpm. Which of the following is
the most appropriate initial induction agent?
A. Ketamine
B. Etomidate
C. Propofol
D. Thiopental
🟢 B. Etomidate
🔴 Explanation: Etomidate is the preferred induction agent in hemodynamically unstable patients or those with
,cardiovascular compromise due to its minimal effect on myocardial contractility and systemic vascular resistance. It
provides stable hemodynamics, making it suitable for this hypertensive, tachycardic patient.
2. What is the primary mechanism of action of neostigmine when used for reversal of neuromuscular blockade?
A. Direct stimulation of nicotinic receptors at the neuromuscular junction
B. Inhibition of acetylcholinesterase, increasing acetylcholine availability
C. Antagonism of muscarinic receptors at the post-synaptic membrane
D. Enhancement of presynaptic calcium influx
🟢 B. Inhibition of acetylcholinesterase, increasing acetylcholine availability
🔴 Explanation: Neostigmine is a reversible cholinesterase inhibitor that prevents the breakdown of acetylcholine at
the neuromuscular junction, allowing it to compete with non-depolarizing neuromuscular blocking agents and
restore muscle function.
3. In which type of shock is the use of phenylephrine most indicated as a first-line vasopressor?
A. Septic shock
B. Anaphylactic shock
C. Neurogenic shock
D. Hypovolemic shock
🟢 C. Neurogenic shock
🔴 Explanation: Neurogenic shock results from loss of sympathetic tone, leading to vasodilation and hypotension.
, Phenylephrine, a pure alpha-1 agonist, causes vasoconstriction and is often used to restore vascular tone in this
setting. It is less preferred in other shock states where inotropic support may be more critical.
4. A patient undergoing general anesthesia develops sudden-onset hypotension, tachycardia, hypoxemia, and
increased airway pressures. Which of the following is the most likely diagnosis?
A. Laryngospasm
B. Anaphylactic reaction
C. Pulmonary embolism
D. Tension pneumothorax
🟢 C. Pulmonary embolism
🔴 Explanation: The classic presentation of a pulmonary embolism (PE) includes acute hypotension, tachycardia,
hypoxemia, and elevated airway pressures due to bronchoconstriction. This triad of signs is highly suggestive of PE
in the perioperative setting. Tension pneumothorax typically presents with absent breath sounds and tracheal
deviation.
5. Which of the following volatile anesthetics is associated with the highest risk of malignant hyperthermia?
A. Sevoflurane
B. Desflurane
C. Halothane
D. Isoflurane
