Introduction
,This comprehensive examination is designed to assess the knowledge and competencies required for NUR 242
Medical-Surgical Nursing at Galen College, as part of the curriculum for nursing students progressing through
their clinical education. The exam evaluates understanding of medical-surgical conditions across multiple body
systems, including cardiovascular, respiratory, gastrointestinal, renal, endocrine, neurological, musculoskeletal, and
immune disorders. Questions are structured as multiple-choice and scenario-based items that require critical
thinking, application of nursing interventions, pharmacological knowledge, and sound clinical judgment. Emphasis
is placed on real-world decision-making, patient safety, prioritization, evidence-based practice, and the integration
of pathophysiology, pharmacology, and nursing care to ensure the delivery of high-quality patient care.
SECTION ONE: QUESTIONS 1–100
Question 1
A patient with heart failure is prescribed furosemide (Lasix). Which assessment finding indicates the medication
is having the desired therapeutic effect?
A. Serum potassium level of 3.2 mEq/L
B. Weight loss of 2 pounds in 24 hours
C. Blood pressure of 88/56 mmHg
D. Heart rate of 102 beats per minute
🟢B
,🔴 RATIONALE: Furosemide is a loop diuretic used to reduce fluid volume in heart failure. Weight loss of 2
pounds in 24 hours indicates effective diuresis. Hypokalemia (A) is an adverse effect; hypotension (C) and
tachycardia (D) are signs of excessive diuresis or dehydration.
Question 2
A patient with chronic obstructive pulmonary disease (COPD) has an oxygen saturation of 88% on room air. The
nurse should anticipate which intervention?
A. Administer oxygen at 4 L/min via nasal cannula
B. Administer oxygen at 2 L/min via nasal cannula
C. Prepare for intubation
D. Administer a bronchodilator and reassess
🟢B
🔴 RATIONALE: Patients with COPD and chronic hypercapnia should receive oxygen at low flow rates (1-2
L/min) to maintain SpO2 between 88-92%. High-flow oxygen (A) can suppress the hypoxic drive. Intubation (C)
is reserved for respiratory failure. Bronchodilators (D) may be used but oxygen therapy is the priority.
Question 3
, A patient is admitted with diabetic ketoacidosis (DKA). Which laboratory finding is consistent with this
diagnosis?
A. Serum pH of 7.35
B. Serum bicarbonate of 22 mEq/L
C. Blood glucose of 650 mg/dL
D. Serum potassium of 5.5 mEq/L
🟢C
🔴 RATIONALE: DKA is characterized by hyperglycemia >250 mg/dL, metabolic acidosis (pH <7.30), and low
bicarbonate (<15 mEq/L). A blood glucose of 650 mg/dL is consistent with DKA. The other options are not
consistent with DKA.
Question 4
The nurse is caring for a patient with acute pancreatitis. Which assessment finding requires immediate
intervention?
A. Serum lipase of 300 U/L
B. Abdominal pain rated 6/10
C. Serum calcium of 7.5 mg/dL
D. Bowel sounds present in all quadrants
🟢C
