Question 1
A patient is found to have liver disease, resulting in the removal of a lobe of his liver. Adaptation to the reduced size of the
liver leads to ___________ of the remaining liver cells.
A. Metaplasia
B. Organ atrophy
C. Compensatory hyperplasia
D. Physiologic hyperplasia
Correct Answer
C
Rationale:
When a part of an organ is removed, the remaining cells undergo a process to maintain the overall function of the organ. In this case, the liver
cells (hepatocytes) will compensate for the loss of function by increasing in number through a process called compensatory hyperplasia, which
allows the liver to maintain its essential functions despite the reduced size.
Question 2
An older adult patient comes to the clinic complaining of not being able to do what he used to be able to. You know that
normal changes associated with aging include: (Select all that apply.)
A. Improved blood flow
B. Slowed metabolic rate
C. Decreased brain weight
D. Improved nerve fiber conduction
E. Less respiratory capacity
Correct Answer
B, C, E
Rationale:
As people age, normal physiological changes occur, including a slowed metabolic rate, which is reflected in option B. This is due to a decrease
in the body's ability to produce energy and a reduction in the rate of cellular processes.

,Question 3
A 20-year-old college student has presented to her campus medical clinic for a scheduled Pap smear. The clinician who will
interpret the smear will examine cell samples for evidence of:
A. Changes in cell shape, size, and organization
B. Presence of unexpected cell types
C. Ischemic changes in cell sample
D. Abnormally high numbers of cells
Correct Answer
A
Rationale:
A Pap smear is a screening test designed to detect abnormal cell changes, particularly those that could potentially develop into cervical cancer.
The correct answer focuses on changes in cell shape, size, and organization, as these alterations are indicative of precancerous or cancerous
cell growth, which the clinician will examine for in the Pap smear samples.
Question 4
The parents of a 4-year-old girl have sought care because their daughter has admitted to chewing and swallowing imported
toy figurines that have been determined to be made of lead. Which of the following blood tests should the care team
prioritize?
A. White blood cell levels with differential
B. Red blood cell levels and morphology
C. Urea and creatinine levels
D. Liver function panel
Correct Answer
B
Lead -> anemia, RBC lysis
You know it's not A because there is no infection involved. C is focused on kidney function while D is focused on liver
function. Both of these would be important in the case of lead poisoning BUT the priority answer is B, because you need
first to address the most life-threatening patient needs. The little girl in this question can go into shock or suffer
permanent organ damage if her RBCs are low.
Rationale:
The priority blood test in this scenario is based on the potential acute toxic effects of lead, which primarily cause damage to the hematopoietic
system by disrupting red blood cell production and function, leading to anemia and RBC lysis. By assessing red blood cell levels and
morphology, the care team can quickly identify the severity of the anemia and potential complications, such as shock or organ damage,
allowing for prompt and effective management.

,Question 5
A patient with severe peripheral vascular disease has developed signs of dry gangrene on the great toe of one foot. Which
of the following pathophysiologic processes most likely contributed to this diagnosis?
A. Inappropriate activation of apoptosis
B. Bacterial invasion
C. Impaired arterial blood supply
D. Metaplastic cellular changes
Correct Answer
B
Remember that it's not C because to have gangrene, you must have infection
Rationale:
Dry gangrene is a type of tissue death that occurs when the blood supply to an area is severely compromised, preventing oxygen and nutrients
from reaching the tissues. Impaired arterial blood supply (C) is the most likely contributor to this diagnosis because it directly relates to the
underlying cause of peripheral vascular disease, which is a narrowing or obstruction of the arteries, leading to reduced blood flow to the
affected area.
Question 6
Although stress exposure initiates integrated responses by multiple systems, the most important changes are first activated
by which system?
A. Pulmonary
B. Gastrointestinal
C. Neuroendocrine
D. Cardiovascular
Correct Answer
C
Rationale:
The neuroendocrine system plays a crucial role in initiating the body's response to stress, as it releases hormones like cortisol and adrenaline
that prepare the body for the "fight or flight" response. This system's rapid activation allows it to take precedence over other systems, such as
the pulmonary, gastrointestinal, and cardiovascular systems, which respond more slowly to stress exposure.

, Question 7
Which manifestation of stress reflects the non-specific fight or flight response?
A. Decreased pupillary light response
B. Increased GI motility
C. Decreased short-term memory
D. Increased cardiopulmonary rates
Correct Answer
D
This would fall under physiologic responses to stress!! Slide 25 in your lecture powerpoint
Rationale:
The non-specific fight or flight response is characterized by the activation of the sympathetic nervous system, which prepares the body to
respond to threats by increasing energy and alertness. Option D, "Increased cardiopulmonary rates," reflects this response by accelerating
heart rate and breathing, allowing for the rapid distribution of oxygen and energy to the body.
Question 8
Stress-induced cortisol hormone secretion is associated with:
A. Increased growth hormone level
B. Regulation of the stress response
C. Increased thyroid-stimulating hormone
D. Depressed adrenal gland function
Correct Answer
B
You know it's not A because I mentioned in an earlier slide that growth hormone levels decrease with stress. We didn't
mention thyroid-stimulating hormone as one of the ones associated with the stress repsonse so you can pretty much
assume that's not right. And we know adrenal function is not depressed because ACTH from the anterior pituitary
stimulates the adrenal glands to release cortisol.
Rationale:
This correct answer is because growth hormone levels decrease with stress, and thyroid-stimulating hormone is not associated with the stress
response, eliminating options A and C. The correct answer is supported by the understanding that ACTH stimulates the adrenal glands to
release cortisol, indicating that adrenal function is not depressed, thereby ruling out option D.
