Introduction
This comprehensive practice examination is designed to rigorously assess your
knowledge and critical thinking skills in pathophysiology, preparing you for success
on your Rasmussen Patho Exam 2. This testbank covers core concepts from cellular
dysfunction to complex multi-system disorders, emphasizing the underlying
mechanisms of disease. Each of the 200 multiple-choice questions is presented in a
scenario-based format, challenging you to apply theoretical knowledge to clinical
situations. The inclusion of detailed rationales for every answer reinforces learning
by explaining the 'why' behind the correct choice. This resource is intended to build
confidence and enhance decision-making skills essential for clinical practice.
Mastery of this material is crucial for understanding the physiological basis of
nursing interventions and providing safe, effective patient care.
SECTION ONE: QUESTIONS 1 – 50
,1. A patient presents with fatigue, pallor, and shortness of breath. Laboratory
results reveal a low hematocrit, low hemoglobin, and microcytic, hypochromic
red blood cells. Which of the following is the most likely underlying cause of
this patient's condition?
A. Vitamin B12 deficiency
B. Chronic blood loss leading to iron deficiency
C. Autoimmune destruction of parietal cells
D. Bone marrow suppression
🟢 Correct Answer: B. Chronic blood loss leading to iron deficiency
🔴 Explanation: The presentation of microcytic, hypochromic anemia with fatigue
and pallor is classic for iron deficiency anemia. The most common cause of iron
deficiency in adults is chronic blood loss, which depletes the body's iron stores,
leading to decreased hemoglobin synthesis. Vitamin B12 deficiency and
autoimmune destruction of parietal cells lead to macrocytic (megaloblastic)
anemia, not microcytic. Bone marrow suppression typically results in
pancytopenia.
2. During a severe asthma attack, a patient's arterial blood gas (ABG) reveals a
pH of 7.25, PaCO2 of 55 mmHg, and HCO3- of 24 mEq/L. How should the nurse
interpret this ABG?
A. Uncompensated metabolic acidosis
B. Fully compensated respiratory alkalosis
C. Uncompensated respiratory acidosis
D. Partially compensated respiratory acidosis
🟢 Correct Answer: D. Partially compensated respiratory acidosis
,🔴 Explanation: The pH is low (acidemia) and the PaCO2 is high (respiratory
acidosis). The HCO3- is normal at 24 mEq/L, indicating that no significant
metabolic compensation has yet occurred. Because the pH is still abnormal, it is
uncompensated. However, the patient's condition (asthma) is acute, and renal
compensation takes 24-48 hours, making D the most accurate description of the
current state. A is incorrect because the primary disturbance is respiratory. B is
incorrect as pH is acidic. C is accurate but D is more specific given the possibility
of early compensation not yet reflected in HCO3-.
3. A patient with a history of chronic obstructive pulmonary disease (COPD) is
admitted with increasing confusion and lethargy. The nurse notes that the
patient's breathing is shallow and slow. The patient's ABG results are: pH 7.30,
PaCO2 68 mmHg, HCO3- 34 mEq/L. What is the primary mechanism leading to
this patient's acid-base imbalance?
A. Hypoventilation leading to carbon dioxide retention
B. Hyperventilation leading to excessive carbon dioxide elimination
C. Increased production of metabolic acids due to tissue hypoxia
D. Renal excretion of bicarbonate due to diuretic therapy
🟢 Correct Answer: A. Hypoventilation leading to carbon dioxide retention
🔴 Explanation: This ABG shows respiratory acidosis, indicated by the low pH and
elevated PaCO2. In a COPD patient, air trapping and decreased alveolar
ventilation lead to hypoventilation and chronic CO2 retention. The elevated
HCO3- (34 mEq/L) indicates metabolic compensation by the kidneys over a
period of days. The confusion and lethargy are signs of CO2 narcosis. Options B
and D are incorrect as they would cause alkalosis. Option C could contribute but
is not the primary mechanism in COPD.
, 4. A patient undergoing chemotherapy is at risk for tumor lysis syndrome.
Which laboratory finding is most indicative of this complication?
A. Hyperkalemia, hyperuricemia, and hyperphosphatemia
B. Hypokalemia, hypocalcemia, and hyponatremia
C. Elevated liver enzymes and leukocytosis
D. Decreased platelet count and prolonged PT/INR
🟢 Correct Answer: A. Hyperkalemia, hyperuricemia, and hyperphosphatemia
🔴 Explanation: Tumor lysis syndrome is characterized by the rapid release of
intracellular contents from lysed cancer cells. This results in hyperkalemia,
hyperuricemia (from nucleic acid breakdown), and hyperphosphatemia. Calcium
may be low because it precipitates with phosphate. The syndrome can lead to
acute kidney injury, cardiac arrhythmias, and seizures. The other options list
findings not classically associated with the primary metabolic derangements of
tumor lysis syndrome.
5. A patient with a history of heart failure is administered a loop diuretic. The
nurse should monitor for which of the following adverse effects?
A. Hyperkalemia and metabolic acidosis
B. Hypokalemia and metabolic alkalosis
C. Hypernatremia and respiratory alkalosis
D. Hypocalcemia and respiratory acidosis
🟢 Correct Answer: B. Hypokalemia and metabolic alkalosis
🔴 Explanation: Loop diuretics (e.g., furosemide) block the Na-K-2Cl transporter
in the thick ascending limb of the loop of Henle. This leads to increased sodium,
potassium, and chloride excretion. The loss of potassium and hydrogen ions (due
to increased sodium reabsorption in the distal tubule in exchange for K+ and H+)
