Perioperative Mastery Assessment Integrating 2025 Evidence-Based Guidelines, Advanced
Clinical Decision-Making, and Complex Patient Management Scenarios
Domain 1: Advanced Preoperative Assessment and Risk Stratification (Questions 1–20)
, 2
1. A 68-year-old patient with a history of coronary artery disease, chronic kidney disease stage
4, and poorly controlled type 2 diabetes (HbA1c 9.4%) is scheduled for an elective open
abdominal aortic aneurysm repair. The perioperative nurse identifies which of the following
as the HIGHEST priority for preoperative optimization?
A. Achieving a fasting blood glucose between 80-110 mg/dL
B. Optimizing blood pressure to < 130/80 mmHg
C. Coordinating with nephrology for perioperative renal replacement therapy planning
D. Ensuring the patient has completed a preoperative cardiac stress test
-detailed answer 100% correct :- C
Rationale: In a patient with CKD stage 4 (eGFR < 30 mL/min) undergoing a major vascular
procedure with significant fluid shifts and potential contrast exposure, the highest priority is
coordinating with nephrology for perioperative renal replacement therapy planning. This
patient is at high risk for acute kidney injury requiring dialysis. While glycemic control, blood
pressure optimization, and cardiac evaluation are all important, the immediate perioperative
risk of renal failure requiring emergent dialysis poses the greatest threat to patient safety and
requires proactive planning.
2. During the preoperative verification process, the circulating nurse identifies that the
patient's surgical consent form lists a different procedure than what is documented in the
surgeon's preoperative note. The surgeon is not immediately available. What is the nurse's
MOST appropriate action?
A. Proceed with the procedure as the surgeon will address it before incision
B. Contact the surgeon immediately and delay all preparations until the discrepancy is resolved
C. Ask the patient which procedure they are scheduled for and document the response
D. Proceed with preparing the patient while attempting to reach the surgeon
-detailed answer 100% correct :- B
Rationale: Any discrepancy between the consent form and the surgeon's documented plan
constitutes a critical patient safety issue that must be resolved before proceeding. The nurse
must contact the surgeon immediately and delay all preparations until the discrepancy is
resolved. The Universal Protocol requires that the correct procedure, site, and patient be
verified before any invasive intervention. Asking the patient is not sufficient as patients may not
, 3
fully understand medical terminology or may have been consented for a procedure that was
subsequently modified.
3. A patient scheduled for an elective total hip arthroplasty reports taking the following
medications: apixaban (discontinued 48 hours ago), metformin 1000 mg BID, lisinopril 20 mg
daily, and atorvastatin 40 mg daily. The patient also reports using over-the-counter fish oil
supplements. Which medication or supplement poses the GREATEST ongoing risk for
perioperative bleeding that the nurse must urgently address?
A. Metformin
B. Lisinopril
C. Fish oil supplements
D. Atorvastatin
-detailed answer 100% correct :- C
Rationale: Fish oil supplements have antiplatelet effects and can increase bleeding risk. They
should typically be discontinued 7 days before surgery. While apixaban was appropriately held
48 hours prior (though some protocols recommend 72 hours for this specific agent), the fish oil
supplement represents an ongoing and potentially unrecognized bleeding risk. Metformin is
held for glycemic management and lactic acidosis prevention, lisinopril for hypotension
prevention, and atorvastatin is generally continued perioperatively for its pleiotropic cardiac
benefits.
4. A 45-year-old patient with no significant medical history is scheduled for an elective
laparoscopic cholecystectomy. The preoperative electrocardiogram (ECG) shows new-onset
left bundle branch block (LBBB). What is the nurse's MOST appropriate action?
A. Document the finding and proceed as scheduled
B. Notify the anesthesia provider and surgeon immediately for further cardiac evaluation
C. Reassure the patient that LBBB is benign and proceed
D. Obtain a baseline troponin level
-detailed answer 100% correct :- B
Rationale: New-onset LBBB in an asymptomatic patient requires further cardiac evaluation
before proceeding with elective surgery. LBBB can indicate underlying structural heart disease
or conduction system disease and may be associated with increased perioperative cardiac risk.
, 4
The nurse must notify the anesthesia provider and surgeon immediately to determine if further
evaluation (echocardiogram, cardiology consultation) is needed before proceeding.
5. A patient with a history of obstructive sleep apnea (OSA) using CPAP at 12 cm H₂O is
scheduled for outpatient laparoscopic inguinal hernia repair. Which preoperative intervention
is MOST critical for this patient's safety?
A. Instruct the patient to bring their CPAP machine for postoperative use
B. Schedule the patient as the first case of the day
C. Administer preoperative sedatives to reduce anxiety
D. Ensure the patient fasts for 12 hours
-detailed answer 100% correct :- A
Rationale: Patients with OSA are at significantly increased risk for postoperative respiratory
complications, particularly airway obstruction and hypoxia related to anesthesia and opioid
analgesia. The patient must bring their CPAP machine for postoperative use, and the settings
should be verified. Scheduling as first case may help but is not the critical intervention.
Preoperative sedatives should be minimized or avoided due to the risk of respiratory
depression.
6. A patient scheduled for a Whipple procedure (pancreaticoduodenectomy) has a
preoperative serum albumin of 2.1 g/dL and a prealbumin of 10 mg/dL. Which nursing
intervention is MOST appropriate based on these findings?
A. Proceed with surgery as planned
B. Notify the surgeon and coordinate nutrition support consultation
C. Administer intravenous albumin immediately
D. Document the findings and continue with preparation
-detailed answer 100% correct :- B
Rationale: A serum albumin of 2.1 g/dL and prealbumin of 10 mg/dL indicate severe
malnutrition. Malnutrition is associated with increased risk of postoperative complications
including surgical site infections, anastomotic leaks, and delayed wound healing. The nurse
should notify the surgeon and coordinate nutrition support consultation for preoperative
optimization. Intravenous albumin is not indicated for nutritional repletion.
