Samuel Merritt CRNA Interview & Requirements (2026)

Samuel Merritt University selects Doctor of Nurse Anesthesia Practice (DNAP) interviewees through holistic review, and its DNAP admissions page notes that meeting or exceeding minimum GPAs does not guarantee an interview invitation. Because applicant volume is high, SMU's Admission Events and Counseling page states that the school does not offer one-on-one admission counseling appointments for DNAP applicants, hosting preview days, virtual Q&A sessions, webinars, and current CRNA student panels instead. Your interview invitation email will confirm your exact interview schedule, format, and whether your session is virtual or in person.

Every candidate for admission must meet the program's Technical Standards and align with its core values: Inclusivity, Wellness, Integrity, Grit, and Professionalism. In the interview, those standards translate directly into how clearly you reason through high-acuity ICU pathophysiology and pharmacology, and how calmly you handle stress and constructive criticism.

To rehearse clinical, pharmacology, and behavioral questions out loud before interview day, Confetto runs AI mock interviews for CRNA applicants with follow-up questions that push on your receptor mechanisms and clinical reasoning. Start your free week to practice on camera or audio. You can also compare formats across programs in our CRNA school interviews guide.

• Intellectual-conceptual and quantitative reasoning: SMU's technical standards require candidates to interpret complex physiologic data, understand causal connections, formulate a hypothesis, and reach fact-based conclusions. Expect interviewers to take a patient from your ICU unit and push past your first answer into cellular mechanisms and hemodynamic trade-offs.
• Behavioral and social attributes under stress: Candidates must employ sound judgment promptly under physically and mentally taxing workloads, accept constructive criticism, and maintain empathy and integrity. Expect behavioral questions that test grit, self-awareness after a clinical mistake, and how you respond to feedback.
• Mission and cultural competency: SMU's mission is to educate vigilant clinicians and healthcare leaders who exercise cultural competency across the full scope of anesthesia practice, rotating across diverse clinical sites from urban trauma centers to rural critical access hospitals.

Because SMU requires every applicant to be an actively practicing ICU nurse with at least 24 months and 4,160 hours of critical care experience, your interview will test whether you understand the physiology and pharmacology behind the drips, ventilators, and monitors you manage on shift. SMU's curriculum also places heavy weight on pharmacology and verbal clinical defense, including a dedicated Pharmacology Comprehensive Exam in Semester 7 (NURSG 7027) and an Oral Comprehensive Exam in Semester 8 (NURSG 7028). Our team wrote the practice questions and labeled sample answers below to match SMU's ICU eligibility rules, technical standards, and core values. For more prompts, see our CRNA school interview questions with answers.

• Hemodynamics and shock: Walk me through how you differentiate septic shock from cardiogenic shock on your unit, which vasoactive agent you reach for first in each, and which receptors those drugs target.
• Vasopressor pharmacology: Compare norepinephrine, phenylephrine, epinephrine, and vasopressin. Why would you add vasopressin in refractory septic shock when high-dose norepinephrine is losing effect?
• Induction and RSI drugs: Compare etomidate, propofol, and ketamine for intubating a hypotensive trauma patient. How does each drug affect systemic vascular resistance, myocardial contractility, and cerebral perfusion?
• Neuromuscular blockers: Explain the mechanism of action of succinylcholine versus rocuronium at the neuromuscular junction. In which ICU patients is succinylcholine contraindicated, and why?
• Ventilator and ABG management: Your intubated ARDS patient has an ABG of pH 7.22, PaCO2 62, PaO2 58, HCO3 25 on FiO2 0.80 and PEEP 10. Interpret the gas and walk through your next ventilator adjustments and why.
• Autonomic physiology: What happens to heart rate when you give a pure alpha-1 agonist like phenylephrine, and what is the exact physiologic pathway of that reflex?
• Core values (Grit and Integrity): Tell us about a time in the ICU when you missed a clinical sign or made an error. How did you handle it in the moment, and how did you respond to the feedback afterward?
• Core values (Inclusivity and Cultural Competency): SMU's mission emphasizes vigilance and cultural competency across diverse practice settings. Tell us about a patient or family whose cultural or socioeconomic background required you to change your care plan.

Use these three worked examples to hear the specificity a doctoral panel looks for: receptor subtypes, secondary physiologic reflexes, and direct ownership in behavioral stories.

Question 1 (Pharmacology): Compare norepinephrine and phenylephrine. When would phenylephrine be the wrong choice for a hypotensive patient in your ICU?

"Norepinephrine is primarily a potent alpha-1 adrenergic agonist with modest beta-1 agonist activity. The alpha-1 activation on vascular smooth muscle increases Gq protein signaling, intracellular calcium, and vasoconstriction, which raises systemic vascular resistance and mean arterial pressure. Its beta-1 activity on the myocardium supports inotropy and chronotropy, helping preserve cardiac output against that higher afterload. Phenylephrine is a pure alpha-1 agonist with no beta-1 activity. Because it raises SVR without any direct positive inotropic or chronotropic support, the carotid sinus baroreceptors sense the jump in blood pressure and trigger a vagally mediated reflex bradycardia. On my CVICU unit, phenylephrine would be the wrong choice for a patient in cardiogenic shock or severe systolic heart failure with a low cardiac index and sinus bradycardia. Clamping down their afterload with pure alpha-1 stimulation without beta-1 support will further drop stroke volume and cardiac output. On the other hand, if I have a patient with severe aortic stenosis or hypertrophic obstructive cardiomyopathy who becomes hypotensive and tachycardic, phenylephrine is helpful because the increased SVR and reflex drop in heart rate improve diastolic coronary filling time."

Question 2 (Clinical scenario): You are preparing to intubate a 68-year-old septic patient with a blood pressure of 82/44 and a potassium of 5.9 mEq/L. Which induction agent and paralytic would you anticipate, and which would you avoid?

"First, before pushing any induction medication, I want hemodynamic optimization underway, including a fluid bolus if volume responsive and a norepinephrine infusion running or a push-dose pressor in hand, because positive-pressure ventilation and loss of sympathetic tone on induction can precipitate cardiac arrest. For the induction agent, I would avoid a standard induction dose of propofol because propofol causes dose-dependent vasodilation and myocardial depression, which will drop this patient's preload and SVR further. Between etomidate and ketamine, I would talk through the trade-offs: etomidate preserves SVR and sympathetic tone via GABA-A receptor modulation, though we weigh its transient 11-beta-hydroxylase adrenal suppression in septic shock. Ketamine is an NMDA receptor antagonist that triggers endogenous catecholamine release, supporting heart rate and blood pressure, unless the patient is severely catecholamine-depleted from prolonged shock, where ketamine's direct negative inotropic effect can show up. For the paralytic, with a serum potassium of 5.9, succinylcholine is contraindicated. As a depolarizing neuromuscular blocker, succinylcholine opens nicotinic acetylcholine channels and causes a transient potassium efflux that typically raises serum potassium by 0.5 to 1.0 mEq/L, risking life-threatening hyperkalemic dysrhythmias. I would use high-dose rocuronium at 1.2 mg/kg, a non-depolarizing competitive acetylcholine antagonist, to achieve rapid intubating conditions safely." (Example answer written by our team. The applicant is invented.)

Question 3 (Behavioral / SMU Values): SMU's DNAP values include Integrity and Grit. Tell us about a time you received difficult clinical feedback and what you did with it.

"During my second year in the trauma ICU, I was managing a post-operative exploratory laparotomy patient whose urine output trended down over two hours while his heart rate crept from the 90s into the 110s. His MAP was still holding at 66 on a low-dose norepinephrine drip, so I waited until morning rounds to bring up the trend instead of paging the surgical resident overnight. The patient was compensated but hypovolemic, and the attending surgeon pulled me aside after rounds and told me plainly that relying on a normal MAP while ignoring compensatory tachycardia and oliguria was passive nursing, not critical care vigilance. That stung, because I prided myself on being thorough. I owned it without making excuses, apologized, and asked the attending what triggers he wanted called immediately overnight. That week I changed how I run my shift assessments: I stopped treating a MAP of 65 on pressors as reassurance and started pairing shock index, urine output, lactate trends, and pulse pressure variation at every two-hour check. Six months later, that same habit helped me catch an occult retroperitoneal bleed early on night shift." (Example answer written by our team. The applicant is invented.)

Once you receive an interview invitation, use this checklist written by our team to organize your clinical and behavioral prep around SMU's curriculum and clinical footprint.

• Days 1 to 3, Audit your ICU patient flowsheet: Pick three high-acuity patients you cared for in the last month. Write down every vasoactive drip, sedative, paralytic, and ventilator mode they were on. For each drug, drill the exact receptor, intracellular second messenger, onset, half-life, metabolism, and one contraindication.
• Days 4 to 6, Drill shock and ABG scenarios out loud: Practice explaining septic, cardiogenic, hypovolemic, and obstructive shock profiles (CI, SVR, CVP, PCWP, SvO2) without looking at notes. Run five arterial blood gases out loud, stating both the acid-base disorder and the exact ventilator or physiologic fix.
• Days 7 to 9, Map stories to SMU's values: Write one concise ICU story for each of SMU's DNAP values: Inclusivity, Wellness, Integrity, Grit, and Professionalism. Make sure your Integrity and Grit stories include a real clinical challenge or critique and what you changed afterward.
• Days 10 to 12, Know SMU's curriculum and clinical network: Review the 9-semester, 94-unit sequential curriculum and the clinical site list on SMU's DNAP page. Be ready to explain why SMU's hybrid format, its 1993 joint-venture roots with Kaiser Permanente Northern California, and its 24-month clinical residency across independent CRNA, care team, and medical direction sites fit your training goals.
• Days 13 to 14, Run two full timed mock interviews: Practice answering a mix of clinical physiology, pharmacology, and behavioral questions back-to-back on camera so you stay composed when an interviewer interrupts with a follow-up question.

SMU's DNAP admissions page enforces strict cutoffs, and applicants below the minimums are ineligible to apply. Compare SMU's rules with national norms in our CRNA school requirements guide.

• Active ICU nursing (24 months and 4,160 hours): You must be actively practicing as an ICU RN at the time of application with at least 24 months and 4,160 hours of critical care RN experience within the last 5 years, excluding hours obtained in a Nurse Residency Program or New Graduate Program. Qualifying units are Surgical, Medical, Trauma, Cardiovascular, Neurosurgical, Burn, Neonatal, CT, or Pediatric ICU. Medical-surgical, step-down, telemetry, Emergency Department, pre-hospital, and PACU (Recovery) do not count.
• Three 3.25 GPA minimums and repeat rules: You need a minimum 3.25 cumulative GPA, 3.25 last 60 semester or 90 quarter units GPA, and 3.25 science coursework GPA. All coursework must be completed before you apply, and in-progress courses are not considered. You can email admission@samuelmerritt.edu for the Pre-Application Guide to self-evaluate prerequisites. Currently, SMU allows up to 3 repeated science courses to replace prior grades if the unit count, term system, and learning objectives match and you upload both original and repeated syllabi. Starting in the 2028 admissions cycle, SMU will no longer accept repeat coursework for grade replacement.
• Certifications and CRNA shadowing (8 hours): AHA-approved BLS, ACLS, PALS, and CCRN (adult, pediatric, neonatal, or critical care) are required at matriculation and throughout the program. You must also complete at least 8 hours of clinical shadowing with a CRNA. Shadowing a physician anesthesiologist does not fulfill this requirement.
• Degree, California RN license, and eligibility: You need a bachelor's, master's, or doctoral degree in nursing from a regionally accredited institution and a current, active, unencumbered California RN license at matriculation and throughout the program. Applicants currently or previously enrolled in another nurse anesthesia program are ineligible, and per the NBCRNA NCE Handbook cited by SMU, students convicted of or pleading no contest to a crime cannot sit for certification.

Your septic shock patient in the ICU is on norepinephrine at 0.25 mcg/kg/min and their MAP is still 54 mmHg. Why is the norepinephrine losing effectiveness, what second-line vasopressor do you anticipate adding, and what is its exact receptor mechanism?
