NR507/ NR 507 FINAL EXAM (2026)
ADVANCED PATHOPHYSIOLOGY QUES &
ANS - TO PASS THE EXAM, 100% VERIFIED
1. What phrase describes the condition in which a series of alveoli in the left lower lobe receive
adequate ventilation but lack adequate perfusion?
A. A right to left shunt
B. Alveolar dead space
C. A low ventilation-perfusion ratio
D. Pulmonary hypotension
Answer: B. Alveolar dead space
Rationale: Alveolar dead space occurs when alveoli are ventilated but not perfused with blood,
resulting in wasted ventilation. Unlike a shunt (where perfusion exists without ventilation), alveolar
dead space reduces effective gas exchange because oxygen cannot enter the blood. Common
causes include pulmonary embolism or severe hypotension.
2. A function of the pericardium is to:
A. Provide a barrier against extracardial infections
B. Improve blood flow through the heart
C. Play a role in cardiac conduction
D. Assist in cardiac contraction
Answer: A. Provide a barrier against extracardial infections
Rationale: The pericardium is a double-layered sac surrounding the heart that protects it from
infection and physical trauma. While it allows limited movement and prevents overexpansion of the
heart, it does not directly aid contraction or conduction.
,3. Clinical manifestations of bile salt deficiencies are related to poor absorption of:
A. Fats & fat-soluble vitamins
B. Proteins
C. Carbohydrates
D. Water-soluble vitamins
Answer: A. Fats & fat-soluble vitamins
Rationale: Bile salts emulsify dietary fats and aid in absorption of fat-soluble vitamins (A, D, E, K). A
deficiency leads to steatorrhea (fatty stools), diarrhea, and deficiencies in fat-soluble vitamins.
4. When should the FNP include innate immunity in patient education?
A. Following an illness
B. At birth
C. Via injection of specific antibodies
D. In adulthood
Answer: B. At birth
Rationale: Innate immunity is the body’s first line of defense and is present at birth. It provides
non-specific protection against pathogens, unlike adaptive immunity, which develops over time or
through immunizations.
5. A 10-year-old develops pneumonia. Physical exam reveals subcostal and intercostal retractions.
The child reports difficulty breathing, saying, “I can’t get enough air.” What term should the FNP
use to document this condition?
A. Cyanosis
B. Dyspnea
C. Hyperpnea
D. Orthopnea
,Answer: B. Dyspnea
Rationale: Dyspnea refers to the subjective sensation of difficulty breathing or shortness of breath.
Retractions and increased work of breathing are objective signs that accompany dyspnea,
particularly in pediatric patients with respiratory infections.
6. When reviewing lab results, the FNP notices erythrocytes with abnormally low hemoglobin
concentration. These erythrocytes are called:
A. Hyperchromic
B. Hypochromic
C. Macrocytic
D. Microcytic
Answer: B. Hypochromic
Rationale: Hypochromic erythrocytes have reduced hemoglobin content, appearing paler under a
microscope. This is often seen in iron-deficiency anemia. Hyperchromic refers to overly pigmented
cells, while macrocytic/microcytic refer to cell size abnormalities.
7. A 45-year-old complains of heartburn after eating and difficulty swallowing. These symptoms
support which diagnosis?
A. Pyloric stenosis
B. Gastroesophageal reflux disease (GERD)
C. Peptic ulcer disease
D. Hiatal hernia
Answer: B. Gastroesophageal reflux disease (GERD)
Rationale: GERD results from reflux of gastric contents into the esophagus, causing heartburn,
dysphagia, and possible esophagitis. Pyloric stenosis primarily affects infants, causing projectile
vomiting, while hiatal hernia may exacerbate reflux but is not the primary diagnosis.
, 8. A patient experiences acute blood loss. Which adaptation should the nurse expect?
A. Movement of fluid into the cell
B. Decreased cardiac output
C. Decreased oxygen release from hemoglobin
D. Peripheral vasoconstriction
Answer: D. Peripheral vasoconstriction
Rationale: In acute blood loss, the body compensates by constricting peripheral blood vessels to
maintain perfusion to vital organs. Cardiac output initially may rise, and oxygen delivery is
maintained through increased heart rate and hemoglobin oxygen unloading.
9. Which patient will develop active immunity?
A. Natural exposure to an antigen or receives an immunization
B. Receives preformed antibodies or T cells from a donor
C. Has T cells that become B cells
D. Receives immunoglobulin
Answer: A. Natural exposure to an antigen or receives an immunization
Rationale: Active immunity occurs when the body mounts its own immune response, producing
memory cells after infection or vaccination. Passive immunity (B/D) provides temporary protection
without long-term memory.
10. Chronic gastritis is classified according to:
A. Severity
B. Location of lesions
