NR283 Pathophysiology Exam 1: Comprehensive
300-Question Study Guide with Detailed Rationales
This comprehensive exam guide is meticulously designed around the
core concepts of the NR283 Pathophysiology Exam 1 study guide,
covering cellular injury, respiratory pathology, and genetic disorders.
1. According to the study guide, which of the following best defines apoptosis?
A. Traumatic cell death resulting in inflammation
B. Programmed cell death
C. Ischemic cell death due to oxygen deficit
D. Necrotic cell death due to bacterial infection
Rationale: The study guide explicitly states that apoptosis is preprogrammed cell death. Unlike
necrosis, apoptosis is a normal, regulated process of cellular self-destruction.
2. A patient presents with a persistent secondary E. coli infection. What type of necrosis does
the study guide indicate this will cause?
A. Coagulative necrosis
B. Fat necrosis
C. Liquefaction necrosis
D. Caseous necrosis
Rationale: The guide specifies that a secondary E. coli infection causes liquefaction necrosis,
characterized by dead cells that liquefy due to the persistent bacterial infection.
,3. What is the primary pathophysiological mechanism of liquefaction necrosis in the context
of an E. coli infection?
A. Dead cells liquify because of persistent E. coli infections
B. The cells harden and calcify due to bacterial toxins
C. The cells undergo programmed cell death without inflammation
D. Ischemia causes the cells to shrink and become rigid
Rationale: The study guide directly links the mechanism of liquefaction necrosis to the persistent
nature of E. coli infections, resulting in the liquefaction of dead cells.
4. The study guide defines ischemia as:
A. An overabundance of oxygen in the tissues
B. A deficit of oxygen in the cells
C. The programmed death of platelets
D. An inflammatory response in the alveoli
Rationale: Ischemia is clearly defined in the guide as a deficit of oxygen in the cells.
5. A patient is diagnosed with pneumonia. According to the study guide, what respiratory
condition develops as a result?
A. Ischemia
B. Apoptosis
C. Hypoxia
D. Alpha-fetoprotein deficiency
Rationale: The guide states that hypoxia develops with pneumonia.
6. What pathological response triggers hypoxia in a patient with pneumonia?
A. A decrease in platelet production
B. Inflammation in the airway leading to impaired oxygen diffusion in the alveoli
C. Excessive alpha-fetoprotein in the lungs
D. Increased apoptosis of lung epithelial cells
Rationale: The guide explains that as pneumonia develops, it triggers a pathological response
and inflammation in the airway. This leads to a decrease or impairment of oxygen diffusion in
the alveoli in the lungs, resulting in hypoxia.
,7. What is the normal lifespan of platelets according to the study guide?
A. 2-3 days
B. 7-10 days
C. 14-21 days
D. 30 days
Rationale: The guide specifically notes that the lifespan of platelets with apoptosis is 7-10 days.
8. The study guide notes that alpha-fetoprotein occurring in a fetus can lead to:
A. Down syndrome
B. Immature lung development
C. Huntington's disease
D. Increased platelet apoptosis
Rationale: According to point 6 of the study guide, alpha-fetoprotein that occurs in a fetus can
lead to immature lung development.
9. Which of the following describes amniocentesis?
A. A surgical procedure to remove a fetus with genetic disorders
B. In utero testing for abnormalities or genetic disorders where a small amount of amniotic
fluid is withdrawn
C. A blood test performed on the mother to check for alpha-fetoprotein
D. A test performed before 14 weeks to check for lung maturity
Rationale: The guide defines amniocentesis as an in utero test for abnormalities or genetic
disorders where a small amount of amniotic fluid is withdrawn.
10. During an amniocentesis, what specific components are analyzed from the withdrawn
amniotic fluid?
A. Maternal white blood cells
B. Sloughed fetal cells
C. Alpha-fetoprotein
D. Platelets
Rationale: The guide specifies that along with the amniotic fluid, sloughed fetal cells are
withdrawn and tested.
, 11. According to the study guide, when is amniocentesis typically performed?
A. Before 10 weeks
B. After 14 weeks
C. After 14 weeks
D. At exactly 7-10 days
Rationale: The guide explicitly states that amniocentesis is performed after 14 weeks.
12. Amniocentesis is noted in the study guide as a common test for which condition?
A. Pneumonia
B. Huntington's disease
C. Down syndrome
D. E. coli infections
Rationale: The study guide lists Down syndrome as a common test indicated by amniocentesis.
13. Which of the following facial features is characteristic of Down syndrome according to the
study guide?
A. Large, protruding ears
B. Small head, round face
C. Long, narrow face
D. High-set ears with pointed tips
Rationale: The guide lists a small head and round face as characteristics of Down syndrome.
14. A nurse is assessing a newborn with suspected Down syndrome. Which facial profile
finding should the nurse expect?
A. Prominent nose with a high bridge
B. Flat nose and facial profile
C. Sunken eyes with a prominent brow
D. Micrognathia (small jaw)
Rationale: The study guide lists a flat nose and facial profile as a characteristic of Down
syndrome.
