ADVANCED MEDICAL-SURGICAL NURSING
CERTIFICATION EXAM: COMPREHENSIVE REVIEW
PACKAGE WITH PRACTICE QUESTIONS AND DETAILED
RATIONALES — 2026–2027 EDITION
This comprehensive examination preparation document is designed for nursing professionals
pursuing advanced credentialing in medical-surgical nursing. The assessment covers critical
care concepts, complex pathophysiology, pharmacological interventions, emergency response
protocols, and professional nursing standards aligned with current national certification
examinations. Candidates preparing for board certification, licensure renewal, or advanced
practice credentialing will benefit from the rigorous question bank that mirrors the cognitive
complexity of actual certification assessments. Each question has been developed to evaluate
clinical reasoning, prioritization skills, and evidence-based practice application. The 2026–2027
edition incorporates the latest clinical guidelines, technological advancements, and regulatory
updates affecting contemporary nursing practice. This resource serves as an essential tool for
identifying knowledge gaps and reinforcing mastery of core competencies required for advanced
nursing practice.

1: A patient with acute decompensated heart failure is receiving dobutamine at 5 mcg/kg/min.
The nurse notes a heart rate increase from 88 to 132 beats/min and frequent premature
ventricular contractions. Which action should the nurse take FIRST?
A) Administer amiodarone 150 mg IV push
B) Decrease the dobutamine infusion rate
C) Obtain a 12-lead electrocardiogram
D) Prepare for synchronized cardioversion

Correct Answer: B
Dobutamine is a beta-1 adrenergic agonist that increases myocardial contractility but also
increases heart rate and can precipitate ventricular dysrhythmias. The development of
tachycardia with PVCs indicates dobutamine toxicity, and the priority intervention is reducing
the infusion rate to decrease adrenergic stimulation. Amiodarone and cardioversion are
interventions for sustained dysrhythmias, while obtaining an ECG would delay the necessary
immediate action.

2: A nurse is interpreting arterial blood gas results for a patient on mechanical ventilation: pH
7.52, PaCO₂ 28 mmHg, HCO₃⁻ 24 mEq/L, PaO₂ 98 mmHg. Which ventilator setting adjustment
is most appropriate?
A) Increase tidal volume
B) Decrease respiratory rate
C) Increase FiO₂
D) Decrease PEEP

Correct Answer: B
The ABG results demonstrate respiratory alkalosis caused by hyperventilation with excessive
minute ventilation. Decreasing the respiratory rate will reduce carbon dioxide elimination and
normalize the pH. Increasing tidal volume would worsen the alkalosis, while adjusting FiO₂ and
PEEP addresses oxygenation, which is already adequate at PaO₂ 98 mmHg.

3: A patient with increased intracranial pressure is being preoxygenated for endotracheal
suctioning. Which finding indicates that suctioning should be terminated immediately?
A) Oxygen saturation of 94%
B) Heart rate increase from 98 to 110 beats/min

,Page 3 of 64

C) Intracranial pressure elevation from 18 to 28 mmHg
D) Mean arterial pressure decrease from 95 to 85 mmHg

Correct Answer: C
A sustained elevation in intracranial pressure above 20 mmHg during suctioning indicates that
cerebral perfusion is being compromised, and the procedure must be stopped immediately to
prevent secondary brain injury. Mild oxygen desaturation and moderate heart rate changes are
expected during suctioning but do not require immediate termination, while a MAP decrease to
85 mmHg still maintains adequate cerebral perfusion pressure in most patients.

4: A patient is receiving continuous renal replacement therapy at 25 mL/kg/hr for acute kidney
injury. The nurse notes the effluent fluid is becoming progressively darker and the patient's blood
pressure is 82/48 mmHg. Which laboratory value should be evaluated FIRST?
A) Serum potassium
B) Hematocrit and hemoglobin
C) Blood urea nitrogen
D) Serum osmolality

Correct Answer: B
Progressive darkening of effluent fluid combined with hypotension suggests active bleeding or
excessive ultrafiltration leading to hemoconcentration. Evaluating hematocrit and hemoglobin
will identify whether the patient is experiencing blood loss or hemoconcentration requiring
intervention. While potassium and BUN are monitored during CRRT, they do not directly explain
the color change in effluent, and serum osmolality is less relevant to this acute presentation.

5: A patient with diabetic ketoacidosis has the following laboratory values: serum glucose 485
mg/dL, potassium 3.1 mEq/L, pH 7.18, HCO₃⁻ 9 mEq/L. Which intravenous fluid and
medication combination should the nurse prepare to administer FIRST?
A) Dextrose 5% in water with insulin infusion
B) Normal saline with potassium chloride supplementation
C) Half-normal saline with sodium bicarbonate
D) Normal saline with regular insulin infusion

, Page 4 of 64

Correct Answer: B
The critically low potassium of 3.1 mEq/L requires immediate supplementation before initiating
insulin therapy because insulin will drive potassium intracellularly, causing life-threatening
hypokalemia. Normal saline addresses the severe dehydration associated with DKA while
potassium replacement stabilizes the cardiac membrane. Insulin should be withheld until
potassium is above 3.3 mEq/L, making options A and D unsafe, and bicarbonate is generally not
indicated unless pH is below 7.0.

6: A patient in septic shock remains hypotensive at 72/40 mmHg despite receiving 30 mL/kg of
crystalloid fluids. Norepinephrine is initiated. Which parameter indicates the goal of therapy is
being achieved?
A) Central venous pressure of 4 mmHg
B) Mean arterial pressure of 68 mmHg
C) Lactate clearance to 4.5 mmol/L
D) Urine output of 0.3 mL/kg/hr

Correct Answer: B
The primary hemodynamic goal in septic shock is achieving a mean arterial pressure of at least
65 mmHg to ensure adequate tissue perfusion. A MAP of 68 mmHg exceeds this threshold and
indicates effective vasopressor therapy. CVP of 4 mmHg is below the recommended target of 8-
12 mmHg, lactate of 4.5 mmol/L remains elevated, and urine output of 0.3 mL/kg/hr is
inadequate, all indicating ongoing shock.

7: A nurse is assessing a patient with suspected acute pancreatitis. Which laboratory finding is
most specific for confirming the diagnosis?
A) Elevated amylase
B) Elevated lipase
C) Elevated alkaline phosphatase
D) Elevated AST

Correct Answer: B
Serum lipase is more specific for acute pancreatitis because it remains elevated longer than
amylase and is produced primarily by the pancreas. Amylase can be elevated due to salivary
