TEAS Practice Test: Video 6 Answers (23 Questions) — Questions and Answers

Question 1: Which bone protects the brain?

Sternum
Cranium (Correct answer)
Vertebrae
Pelvis

Correct answer: Cranium

The cranium is the part of the skull that encloses and protects the brain.

Question 2: The function of the epiglottis is to:

Filter air entering the lungs
Prevent food from entering the airway during swallowing (Correct answer)
Produce mucus in the trachea
Connect the pharynx to the esophagus

Correct answer: Prevent food from entering the airway during swallowing

The epiglottis is a flap of cartilage that covers the trachea during swallowing, directing food into the esophagus and preventing aspiration.

Question 3: Which chamber of the heart pumps oxygenated blood to the body?

Left ventricle (Correct answer)
Left atrium
Right ventricle
Right atrium

Correct answer: Left ventricle

The left ventricle pumps oxygen-rich blood into the aorta and out to the body.

Question 4: Which type of muscle is found in the walls of the stomach and intestines?

Skeletal muscle
Striated muscle
Cardiac muscle
Smooth muscle (Correct answer)

Correct answer: Smooth muscle

Smooth muscle is involuntary and lines hollow internal organs like the digestive tract.

Question 5: Which chamber of the heart pumps oxygenated blood to the body's systemic circulation?

Right ventricle
Left atrium
Left ventricle (Correct answer)
Right atrium

Correct answer: Left ventricle

The left ventricle pumps oxygenated blood received from the left atrium out through the aorta to the systemic circulation.

Question 6: What molecule carries the genetic instructions used to build proteins during translation?

mRNA (Correct answer)
Glycogen
ATP
Cholesterol

Correct answer: mRNA

Messenger RNA carries the codon sequence read by ribosomes during translation.

Question 7: Which process do plant cells use to convert carbon dioxide and water into glucose using light energy?

Cellular respiration
Fermentation
Photosynthesis (Correct answer)
Transpiration

Correct answer: Photosynthesis

Photosynthesis converts CO2 and water into glucose using light energy.

Question 8: What type of macromolecule are enzymes primarily made of?

Lipids
Carbohydrates
Nucleic acids
Proteins (Correct answer)

Correct answer: Proteins

Most enzymes are proteins folded into specific shapes for catalysis.

Question 9: What is the primary role of the spleen in the body?

Producing insulin
Producing digestive enzymes
Filtering blood and recycling old red blood cells (Correct answer)
Synthesizing vitamin D

Correct answer: Filtering blood and recycling old red blood cells

The spleen filters blood, removes old and damaged red blood cells, recycles hemoglobin, and houses immune cells that fight bloodborne pathogens.

Question 10: What is the product of glycolysis?

Glucose-6-phosphate only
Two pyruvate molecules (plus net 2 ATP and 2 NADH) (Correct answer)
ATP only
Acetyl-CoA and CO2

Correct answer: Two pyruvate molecules (plus net 2 ATP and 2 NADH)

Glycolysis converts one glucose (6-carbon) into two pyruvate (3-carbon) molecules, with a net yield of 2 ATP and 2 NADH.

Question 11: What type of pronoun is used in the following sentence? 'The patient gave herself an insulin injection.'

Intensive pronoun
Reflexive pronoun (Correct answer)
Demonstrative pronoun
Personal pronoun

Correct answer: Reflexive pronoun

'Herself' is a reflexive pronoun — it refers back to the subject ('the patient') and indicates the subject is performing the action on herself.

Question 12: Which of the following shows correct comma usage with a non-restrictive clause?

The nurse, who works nights, is tired. (Correct answer)
The nurse who works nights is tired.
The nurse who works nights, is tired.
The nurse who, works nights, is tired.

Correct answer: The nurse, who works nights, is tired.

A non-restrictive (non-essential) clause is set off by commas. 'Who works nights' is non-restrictive here (additional info), so it's correctly enclosed in commas in option B.

Question 13: Which sentence uses a semicolon correctly?

She studied hard; she passed the exam. (Correct answer)
I was tired; so I went to bed.
He likes coffee; and tea.
We left early; because of the storm.

Correct answer: She studied hard; she passed the exam.

A semicolon joins two independent clauses without a coordinating conjunction.

Question 14: In the sentence 'Give the medication to whoever asks for it,' which word is correct?

who
whom
whomever
whoever (correct as written) (Correct answer)

Correct answer: whoever (correct as written)

'Whoever' is correct because it is the subject of the dependent clause 'whoever asks for it.' The subject of a verb needs a subject pronoun (who/whoever).

Question 15: Identify the type of sentence: 'Although the patient was tired, she completed the physical therapy session.'

Complex sentence (Correct answer)
Compound sentence
Compound-complex sentence
Simple sentence

Correct answer: Complex sentence

This is a complex sentence — it contains one independent clause ('she completed the physical therapy session') and one dependent clause ('Although the patient was tired').

Question 16: What is the next term in the sequence: 2, 5, 10, 17, 26, __?

37 (Correct answer)
39
35
33

Correct answer: 37

The differences between terms are 3, 5, 7, 9 (odd numbers increasing by 2). The next difference is 11: 26 + 11 = 37.

Question 17: A nurse earns $28 per hour. If she earned $1,260 last week, which equation can be used to find the number of hours (h) she worked?

h/28 = 1260
h + 28 = 1260
28h = 1260 (Correct answer)
h = 1260 × 28

Correct answer: 28h = 1260

Total earnings = hourly rate × hours worked. So 28h = 1260. Solving: h = 1260/28 = 45 hours.

Question 18: Solve the system of equations: x + y = 10 and x - y = 4

x = 7, y = 3 (Correct answer)
x = 8, y = 2
x = 3, y = 7
x = 6, y = 4

Correct answer: x = 7, y = 3

Add the equations: 2x = 14, so x = 7. Substitute: 7 + y = 10, so y = 3.

Question 19: Which statement is an inference rather than an explicit fact?

The thermometer read 38 degrees Celsius
The patient's temperature was elevated
The patient must be fighting an infection (Correct answer)
The nurse recorded the temperature at noon

Correct answer: The patient must be fighting an infection

Concluding the patient is fighting an infection goes beyond the stated data and is an inference.

Question 20: From "She slid the untouched plate away and stared out the window," the reader can best infer that the character:

Was satisfied with the meal
Was waiting for someone to join her
Had lost her appetite, likely from distress (Correct answer)
Disliked the restaurant's food

Correct answer: Had lost her appetite, likely from distress

Pushing away untouched food and staring away suggests distress that has taken her appetite.

Question 21: What is the primary purpose of a passage that describes how vaccines work, explains herd immunity, and urges readers to vaccinate their children?

To persuade readers to vaccinate their children (Correct answer)
To entertain readers with an interesting topic
To compare vaccines and natural immunity
To inform readers with no particular point of view

Correct answer: To persuade readers to vaccinate their children

The passage informs but also explicitly 'urges readers to vaccinate' — this persuasive call to action identifies the primary purpose as persuasion.

Question 22: An author states a claim and then writes, "Of course, no reasonable person would disagree." This phrasing is an example of:

Statistical evidence
An appeal that discourages questioning the claim (Correct answer)
A neutral transition
A direct citation

Correct answer: An appeal that discourages questioning the claim

Saying no reasonable person would disagree pressures readers to accept the claim without examining it.

Question 23: A study found that students who ate breakfast scored higher on tests. A flawed conclusion would be:

More research could clarify the link
Other factors might also affect scores
Breakfast may be associated with better scores
Eating breakfast guarantees high test scores (Correct answer)

Correct answer: Eating breakfast guarantees high test scores

Claiming breakfast guarantees high scores overstates a correlation as if it were proven causation.
