HESI A2 Entrance Exam Study Guide 2026 | Complete
Review | Graded A+
1. Which one of the following would best define respiration in context of the
respiratory system?
taking O2 into and out of the lungs
exchange of O2 with the atmosphere
exchange of gases between the atmosphere, blood, and cells
the oxidation of glucose in cells
taking air in through the nose and exhaling
2. Atrophy is defined as
the shrinking or wasting of tissue
abnormal enlargement of muscle
a genetic muscle disease
inflammation of joints
3. If a patient has an occluded artery, what potential health issue might they
face?
Reduced blood flow
Enhanced nutrient delivery
Increased oxygen supply
Improved circulation
4. What type of organisms are bacteria classified as?
Fungi
, Single-celled organisms
Multi-celled organisms
Viruses
5. The doctor gave her rationale as to why the patient should assent to the
surgery. RATIONALE:
prognosis
plea
instructions
underlying reason
6. Describe the implications of a condition being labeled as 'fatal' in a medical
context.
It indicates that the condition can lead to death.
It means the condition is temporary.
It suggests that the condition is easily treatable.
It implies that the condition is common.
7. What is the definition of 'distension' in medical terminology?
Distension refers to a decrease in size or volume.
Distension describes a condition that is swollen and protruding out
further than normal.
Distension indicates an increase in blood flow.
Distension is the process of healing a wound.
,8. In medical terminology, what does the term "exacerbation" refer to?
The complete resolution of a medical condition
The initial onset of symptoms in a disease
The temporary worsening or flare-up existing symptoms or a
chronic condition
The preventive measures taken to avoid the occurrence of a health
issue
9. A patient is considered terminal after being involved in a motor vehicle
accident in which they received massive trauma to the head. As the patient's
ICP increases and condition worsens, the family asks you what indications of
approaching death will there be. What would be your best response?
"Loss of brainstem reflexes is a sign of approaching death."
"There is a change in the pattern of their respirations."
"Posturing may develop as pressure on the brainstem increases."
"Projectile vomiting and hemiplegia usually occur just before death."
10. Describe the significance of understanding 'transmission' in healthcare
settings.
Understanding 'transmission' is crucial for preventing the spread of
diseases.
Understanding 'transmission' helps in diagnosing diseases.
Understanding 'transmission' is only relevant for laboratory
technicians.
Understanding 'transmission' is not important in healthcare.
, 11. What is the definition of longevity?
all of the above
how long someone could possibly live
the length of a person's life
how long someone is estimated to live
12. Describe how the concept of 'dynamic' can influence patient care in a
healthcare setting.
The concept of 'dynamic' indicates that patient care should follow a
strict routine.
The concept of 'dynamic' suggests that patient care should be
adaptable and responsive to changing conditions.
The concept of 'dynamic' means that patient care is only focused on
physical health.
The concept of 'dynamic' implies that patient care is irrelevant to
emotional well-being.
13. If a person's body is unable to maintain equilibrium due to a hormonal
imbalance, what physiological consequences might arise?
Improved metabolic efficiency.
Disruption of homeostasis leading to various health issues.
Enhanced immune response.
Increased physical strength.
14. Which of the following best defines prognosis?
A predicted outcome of a disease
