Midterm Practice Exam | Complete Verified
Questions with Accurate Answers &
Rationales | Latest Edition -Updated 2026
Question 1
When endothelial cells are injured, what alteration contributes to atherosclerosis?
Answer: The release of toxic oxygen radicals that oxidize low-density lipoproteins
(LDLs). ✔✔
Rationale: Endothelial injury leads to oxidative stress, where toxic oxygen radicals
oxidize LDLs. Oxidized LDLs are taken up by macrophages, forming foam cells that
contribute to atherosclerotic plaque formation.
Question 2
A patient has been diagnosed with an empyema. What does the healthcare professional
tell the patient about this condition?
Answer: We will have to drain the pus out of your pleural space. ✔✔
Rationale: Empyema is a collection of pus in the pleural space, often requiring
drainage to resolve the infection and prevent complications.
Question 3
A patient has been admitted for a possible small intestinal obstruction. What is the first
sign the healthcare professional assesses for that would indicate the presence of this
condition?
Answer: Vomiting. ✔✔
Rationale: Vomiting is often the earliest sign of small intestinal obstruction due to the
backup of intestinal contents proximal to the blockage.
Question 4
Autocrine stimulation is the ability of cancer cells to do what?
Answer: Secrete growth factors that stimulate their own growth. ✔✔
pg. 1
,Rationale: Autocrine stimulation allows cancer cells to produce and respond to their
own growth signals, promoting uncontrolled proliferation.
Question 5
A patient had a myocardial infarction that damaged the SA node, which is no longer
functioning as the pacemaker of the heart. What heart rate would the healthcare
provider expect the patient to have?
Answer: 40 to 60 beats/min. ✔✔
Rationale: When the SA node fails, the AV node assumes pacemaker function with an
intrinsic rate of 40-60 beats/min.
Question 6
Which type of immunity is produced by an individual after either natural exposure to
the antigen or after immunization against the antigen?
Answer: Active-acquired immunity. ✔✔
Rationale: Active-acquired immunity develops when the individual's immune system
produces antibodies and memory cells after natural infection or vaccination.
Question 7
In teaching a women's community group, which risk factor does the healthcare
professional teach is related to high morbidity of cancer of the colon, uterus, and
kidney?
Answer: Women who have a high body mass index. ✔✔
Rationale: Obesity (high BMI) is a significant risk factor for colon, uterine, and kidney
cancers due to hormonal and metabolic changes.
Question 8
A student asks the healthcare professional to describe exotoxins. Which statement by
the professional is best?
Answer: Exotoxins are released during the lysis of bacteria. ✔✔
Rationale: Exotoxins are proteins released by living bacteria, but they can also be
released upon bacterial lysis; they are highly potent and specific.
pg. 2
, Question 9
A student studying biology asks the professor to describe how the ras gene is involved in
cancer proliferation. What explanation by the professor is best?
Answer: A mutation in this gene allows continuous cell growth. ✔✔
Rationale: The ras gene encodes a protein involved in cell signaling. Mutations cause
constitutive activation, leading to uncontrolled proliferation.
Question 10
A healthcare professional cares for older adults in a skilled nursing facility. What should
the professional assess for in these individuals related to cardiovascular functioning?
Answer: Increased rate of falling and dizzy spells. ✔✔
Rationale: Older adults are at risk for orthostatic hypotension, reduced cardiac output,
and decreased baroreceptor sensitivity, leading to falls and dizziness.
Question 11
A healthcare professional is educating a patient on asthma. The professional tells the
patient that the most successful treatment for chronic asthma begins with which action?
Answer: Avoidance of the causative agent. ✔✔
Rationale: Identifying and avoiding asthma triggers is the cornerstone of effective
asthma management.
Question 12
A healthcare professional is conducting community education on vaccinations. Which
statement about vaccines does the professional include in the presentation?
Answer: Most bacterial vaccines contain attenuated organisms. ✔✔
Rationale: Many bacterial vaccines use attenuated (weakened) live organisms to
stimulate immunity without causing disease.
Question 13
Renal failure is the most common cause of which type of hyperparathyroidism?
Answer: Secondary. ✔✔
Rationale: Renal failure causes secondary hyperparathyroidism due to decreased
vitamin D activation, hypocalcemia, and hyperphosphatemia.
