SECTION 1: ADVANCED PREOPERATIVE RISK STRATIFICATION AND OPTIMIZATION
Question 1
A 68-year-old patient with a history of ischemic cardiomyopathy (ejection fraction 35%), chronic
kidney disease stage 3b (eGFR 42 mL/min/1.73m²), and poorly controlled type 2 diabetes
(HbA1c 8.9%) is scheduled for an open abdominal aortic aneurysm repair. The Revised Cardiac
, 2
Risk Index (RCRI) score is calculated. Which additional preoperative intervention is MOST critical
to reduce perioperative morbidity and mortality?
A. Initiation of a β-blocker titration protocol targeting a resting heart rate of 60-65 bpm
B. Aggressive glycemic control with an insulin infusion targeting blood glucose 80-110 mg/dL
C. Preoperative coronary revascularization prior to the aneurysm repair
D. Administration of preoperative erythropoietin to optimize hemoglobin levels
-detailed answer 100% correct :- A
Rationale: The RCRI score incorporates high-risk surgery, history of ischemic heart disease,
heart failure, cerebrovascular disease, diabetes, and renal insufficiency. For patients with an
elevated RCRI score, perioperative β-blocker therapy has demonstrated mortality benefit when
titrated to a heart rate of 60-65 bpm. While glycemic control (B) is important, the target of 80-
110 mg/dL is too tight and may cause hypoglycemia; current guidelines recommend 140-180
mg/dL. Preoperative coronary revascularization (C) is not routinely indicated unless the patient
has unstable angina or left main disease. Erythropoietin (D) is not indicated in this scenario and
carries thrombotic risks.
Question 2
A 45-year-old patient scheduled for an elective thyroidectomy reports taking 20 mg of
prednisone daily for rheumatoid arthritis for the past 18 months. The patient's morning cortisol
level is 2.1 mcg/dL (normal: 6-23 mcg/dL). Which preoperative management strategy is MOST
appropriate?
A. Continue the current prednisone dose and proceed with surgery
B. Administer stress-dose hydrocortisone 100 mg IV at induction and 50 mg IV every 8 hours
postoperatively
C. Taper the prednisone to 5 mg daily over 7 days before surgery
D. Discontinue prednisone 48 hours before surgery to allow adrenal recovery
-detailed answer 100% correct :- B
Rationale: Chronic corticosteroid use (>3 weeks) suppresses the hypothalamic-pituitary-adrenal
axis, placing the patient at risk for adrenal crisis during surgical stress. A low morning cortisol
(<3 mcg/dL) indicates adrenal suppression. Stress-dose steroids (hydrocortisone 100 mg IV at
induction followed by 50 mg IV q8h) are indicated to prevent adrenal crisis. Continuing the
same dose (A) may be insufficient for the stress response. Tapering (C) does not address the
acute stress requirement. Discontinuing (D) would precipitate adrenal crisis.

Question 3
A patient with severe aortic stenosis (valve area 0.8 cm², mean gradient 55 mmHg) is scheduled
for a non-cardiac surgery. The perioperative nurse should prioritize which assessment finding as
the HIGHEST risk for adverse outcomes?
A. Preoperative serum potassium of 3.4 mEq/L
B. Intraoperative blood pressure variability with systolic pressures ranging from 90-180 mmHg
C. Baseline oxygen saturation of 94% on room air
D. History of controlled hypertension on lisinopril
-detailed answer 100% correct :- B
Rationale: In severe aortic stenosis, patients are preload-dependent and afterload-sensitive.
Wide blood pressure variability (systolic 90-180 mmHg) indicates labile hemodynamics that can
precipitate myocardial ischemia, heart failure, or sudden cardiac death. Maintaining stable
hemodynamics with adequate preload and avoiding hypotension is critical. Potassium of 3.4
mEq/L (A) is mildly low but can be corrected. Oxygen saturation of 94% (C) is acceptable.
Controlled hypertension on lisinopril (D) is not the highest risk factor.
Question 4
A preoperative patient has a hemoglobin of 9.8 g/dL and is scheduled for a total hip
arthroplasty with an estimated blood loss of 500-1000 mL. The patient is a Jehovah's Witness
and has documented refusal of blood products. Which intervention should the perioperative
nurse coordinate FIRST?
A. Administer preoperative erythropoietin and iron supplementation to stimulate erythropoiesis
B. Prepare for intraoperative cell salvage with the patient's consent
C. Inform the surgical team to minimize blood loss using meticulous hemostasis
D. Consult the hospital ethics committee for a blood transfusion override
-detailed answer 100% correct :- A
Rationale: In a Jehovah's Witness patient refusing blood products, proactive optimization is
essential. Preoperative erythropoietin with iron supplementation can increase hemoglobin
levels before surgery, reducing the risk of severe anemia. Cell salvage (B) may be acceptable
depending on the patient's specific beliefs about autologous blood; this requires discussion.
Minimizing blood loss (C) is important but should be done in conjunction with optimization. An
ethics committee consultation (D) is not appropriate to override a competent patient's refusal.

Question 5
A patient scheduled for a laparoscopic cholecystectomy has a preoperative serum sodium of
126 mEq/L. The patient has been taking hydrochlorothiazide for hypertension. Which action
should the perioperative nurse take?
A. Proceed with surgery as the sodium level is not clinically significant
B. Notify the surgeon and anesthesia provider to evaluate and correct the hyponatremia
C. Administer 3% hypertonic saline immediately to correct the sodium
D. Hold the patient's morning dose of hydrochlorothiazide and proceed
-detailed answer 100% correct :- B
Rationale: Hyponatremia (sodium <135 mEq/L) is a significant electrolyte abnormality that can
cause neurological symptoms and worsen with anesthesia and surgery. A sodium of 126 mEq/L
requires evaluation and correction before proceeding with elective surgery. The surgeon and
anesthesia provider must be notified. Rapid correction with 3% hypertonic saline (C) without
knowing the chronicity risks osmotic demyelination. Holding the diuretic (D) is appropriate but
does not address the existing hyponatremia.
Question 6
Which preoperative laboratory finding in an asymptomatic patient scheduled for an elective
procedure would MOST likely prompt postponement of surgery?
A. Serum potassium 5.1 mEq/L
B. White blood cell count 14,500/μL
C. International normalized ratio (INR) 4.2 on warfarin
D. Platelet count 120,000/μL
-detailed answer 100% correct :- C
Rationale: An INR of 4.2 on warfarin represents a significant bleeding risk and requires reversal
or bridging before surgery. The target INR for most surgical procedures is <1.5. This finding
would prompt postponement. A potassium of 5.1 (A) is mildly elevated but not critical. A WBC
of 14,500 (B) may indicate infection but could be reactive. A platelet count of 120,000 (D) is mild
thrombocytopenia that may not require postponement.
