TEAS Practice Test 2026: 50 Free Questions + Answers

Correct answer: A. Plasma

Blood is a connective tissue because its formed elements, erythrocytes, leukocytes, and platelets, are suspended in plasma, which acts as the extracellular matrix. Choosing a cell or platelet as the matrix reverses the structural roles.

From practice test 5 of our TEAS study guide (question 129). Original question, not an official exam item.

Correct answer: C. Carotid sinus

The carotid sinus is a dilation at the bifurcation of the common carotid artery and contains baroreceptors that detect changes in blood pressure. The carotid body is a chemoreceptor, not a baroreceptor.

From practice test 7 of our TEAS study guide (question 124). Original question, not an official exam item.

Correct answer: C. Metalloid

Elements along the stair-step line are metalloids and show properties between metals and nonmetals. A metal would conduct electricity readily, while a nonmetal would not show this conditional conductivity.

From practice test 3 of our TEAS study guide (question 4). Original question, not an official exam item.

Correct answer: C. All cells arise from pre-existing cells.

The swan-neck flask experiment showed that microorganisms did not appear in sterilized broth, so cells could only arise from cells already present. This supports the principle that all cells arise from pre-existing cells.

From practice test 7 of our TEAS study guide (question 66). Original question, not an official exam item.

Correct answer: B. Anyone with a latex allergy is assigned a latex-free kit.

'Anyone' is a singular indefinite pronoun and takes the singular verb 'is.' The other choices pair singular indefinite pronouns with plural verbs or pair the plural indefinite pronoun 'several' with a singular verb.

From practice test 2 of our TEAS study guide (question 164). Original question, not an official exam item.

Correct answer: C. 8

Multiplication and division are performed left to right. Dividing 24 by 6 gives 4, then multiplying by 2 gives 8. Multiplying 6 by 2 first yields 2, which is incorrect.

From practice test 6 of our TEAS study guide (question 18). Original question, not an official exam item.

Correct answer: B. The evacuation showed that clear communication and teamwork save lives in a crisis.

In a narrative passage, the main idea is the significance of the events rather than a timeline or isolated detail. The other choices are specific facts from the narrative or a later outcome, not the larger point the story demonstrates.

From practice test 3 of our TEAS study guide (question 69). Original question, not an official exam item.

Correct answer: C. Superior to the umbilicus and to the left of the midline

LUQ stands for left upper quadrant, which is above the horizontal transumbilical line and to the left of the vertical midline. The other choices describe the LLQ, RUQ, or RLQ.

From practice test 6 of our TEAS study guide (question 98). Original question, not an official exam item.

Correct answer: D. Oxygen and carbon dioxide diffuse through endothelial cells; water and small solutes pass between cells through intercellular clefts; larger proteins and hormones are transported by endocytosis and exocytosis.

Capillary exchange has three routes: lipid-soluble gases diffuse through the endothelial cells, water and small solutes pass through intercellular clefts, and larger molecules use vesicular transport involving endocytosis and exocytosis. The other options reverse or omit one of these routes.

From practice test 2 of our TEAS study guide (question 84). Original question, not an official exam item.

Correct answer: B. Polar covalent

An electronegativity difference above approximately 0.4 and below approximately 1.7 indicates a polar covalent bond. A difference of 0.5 therefore represents a covalent bond in which electrons are shared unequally.

From practice test 5 of our TEAS study guide (question 123). Original question, not an official exam item.

Correct answer: D. The treatment group differed from the control group in both diet and exercise.

Because diet and exercise changed at the same time, any difference in energy could be caused by either variable or both. The experiment violates the rule of changing only one independent variable.

From practice test 2 of our TEAS study guide (question 107). Original question, not an official exam item.

Correct answer: C. When the overnight shift ended, the day nurse accepted the report, and the unit clerk updated the board.

Option C opens with the dependent clause 'When the overnight shift ended' and then contains two independent clauses joined by and. Option A has two independent clauses and no dependent clause, D has one dependent and one independent clause, and B is a simple sentence with a compound predicate.

From practice test 6 of our TEAS study guide (question 96). Original question, not an official exam item.

Correct answer: C. 3/5

The decimal 0.6 is read as six tenths, written as 6/10, and the common factor 2 divides both the numerator and denominator to give the simplest form 3/5. The distractor 6/10 is equal in value but is not simplified; 2/5 would correspond to 0.4, not 0.6.

From practice test 2 of our TEAS study guide (question 115). Original question, not an official exam item.

Correct answer: D. They are the walls: the facts, statistics, and examples that support the main claim about hand hygiene.

The research findings and examples are the supporting details that hold the opening claim up, exactly as walls hold up a roof. The closest error would be to treat those details as restatements of the main idea, but evidence and examples make sense only as support for the claim.

From practice test 8 of our TEAS study guide (question 62). Original question, not an official exam item.

Correct answer: D. Standing upright, face forward, arms at the sides, palms facing forward

Anatomical position requires an upright stance, face forward, arms at the sides, and palms facing forward. The palms-forward hand position is the standard reference for anterior, posterior, medial, and lateral.

From practice test 8 of our TEAS study guide (question 109). Original question, not an official exam item.

Correct answer: D. Fluid is reabsorbed into the capillary because colloid osmotic pressure exceeds hydrostatic pressure

Because hydrostatic pressure has fallen below the colloid osmotic pressure, net reabsorption into the capillary occurs. The statement claiming hydrostatic pressure still exceeds oncotic pressure would only be true at the arterial end.

From practice test 5 of our TEAS study guide (question 142). Original question, not an official exam item.

Correct answer: D. They each have one valence electron in an s orbital

Group 1 atoms have an ns1 outer configuration, and that single s electron drives their similar chemistry. They do not share the same neutron count, total electron count, or number of occupied shells.

From practice test 6 of our TEAS study guide (question 99). Original question, not an official exam item.

Correct answer: A. the reaction time in milliseconds on the task

The dependent variable is the outcome measured to see whether the independent variable had an effect. Reaction time is what the researchers measured, while the coffee type is the independent variable and drink amount plus time of day are factors held constant.

From practice test 5 of our TEAS study guide (question 85). Original question, not an official exam item.

Correct answer: A. The attending physician and the resident coordinate the patient's care plan.

A compound subject joined by 'and' takes a plural verb, so 'coordinate' is correct. The other options use a singular verb with a compound plural subject.

From practice test 6 of our TEAS study guide (question 146). Original question, not an official exam item.

Correct answer: B. 3/5

0.6 is six tenths, so the initial fraction is 6/10. Dividing both terms by 2 gives 3/5, which is simplest form; 6/10 is equivalent but not simplified.

From practice test 8 of our TEAS study guide (question 2). Original question, not an official exam item.

Correct answer: D. Writers typically place main ideas in predictable locations, such as the title and the first or last sentences of paragraphs.

Expository writers usually announce or restate their central point in the title, the opening, or the conclusion, so a guided skim can identify it. The incorrect options rely on absolute claims that do not describe real texts.

From practice test 7 of our TEAS study guide (question 63). Original question, not an official exam item.

Correct answer: A. Antagonist

An antagonist opposes the action of the prime mover. Because the triceps brachii extends the elbow, it opposes the flexor action of the biceps during elbow flexion.

From practice test 8 of our TEAS study guide (question 82). Original question, not an official exam item.

Correct answer: D. The osmotic pressure of plasma proteins exceeds the capillary hydrostatic pressure

Plasma proteins such as albumin exert a colloid osmotic pull of about 25 mmHg. At the venous end, capillary hydrostatic pressure falls to about 15 mmHg, so the osmotic force dominates and draws fluid back into the capillary.

From practice test 8 of our TEAS study guide (question 53). Original question, not an official exam item.

Correct answer: A. Group 1

A Group 1 alkali metal has one valence electron, loses it to form a 1+ ion, and fits a compound formula such as XCl. Group 2 metals form 2+ ions rather than 1+ ions.

From practice test 8 of our TEAS study guide (question 131). Original question, not an official exam item.

Correct answer: A. The bacterial cell is much smaller than the cheek cell.

Prokaryotic cells, including most bacteria, are typically 1 to 5 micrometers in diameter, whereas many eukaryotic cells are about 10 to 100 micrometers. Thus the bacterial cell is generally much smaller than a human cheek cell.

From practice test 3 of our TEAS study guide (question 134). Original question, not an official exam item.

Correct answer: D. After reviewing the lab results, the nurse revised the treatment plan.

The opening phrase implies a person reviewed, so the subject following the comma must be that person, not the treatment plan. Option D names the nurse as the actor and therefore fixes the dangling modifier; option B is the closest distractor because it still leaves no logical subject for 'reviewing.'

From practice test 8 of our TEAS study guide (question 146). Original question, not an official exam item.

Correct answer: C. 3 cups

The number of patients increases by a factor of 9/6 = 1.5, so the water increases by the same factor: 2 × 1.5 = 3 cups. The 2.25-cup option would require a serving ratio of 9:8 rather than 9:6.

From practice test 8 of our TEAS study guide (question 24). Original question, not an official exam item.

Correct answer: B. Patient reports chest tightness

Chest tightness is a symptom reported by the patient, making it subjective data. The other entries are measurable or observable clinical findings, so they are objective data.

From practice test 6 of our TEAS study guide (question 143). Original question, not an official exam item.

Correct answer: C. Anterior and posterior portions

The coronal, or frontal, plane runs vertically from side to side and divides the body into anterior and posterior portions. Sagittal planes separate left and right, and transverse planes separate superior and inferior.

From practice test 4 of our TEAS study guide (question 127). Original question, not an official exam item.

Correct answer: A. Baroreceptor firing decreases, causing withdrawal of parasympathetic tone and sympathetic constriction of arterioles

Standing quickly reduces venous return and lowers arterial pressure, so baroreceptor firing decreases. The cardiovascular center responds by withdrawing parasympathetic tone and increasing sympathetic outflow, which raises heart rate and constricts arterioles to restore blood pressure.

From practice test 3 of our TEAS study guide (question 108). Original question, not an official exam item.

Correct answer: A. Mass number 14 as a superscript to the upper left of N and atomic number 7 as a subscript to the lower left of N

Mass number is the total of protons and neutrons, so this isotope has mass number 14; atomic number is the proton count, 7. Nuclide notation places the mass number as the upper left superscript and the atomic number as the lower left subscript, so writing the atomic number above the mass number reverses the format.

From practice test 2 of our TEAS study guide (question 137). Original question, not an official exam item.

Correct answer: C. The participants' expectation that they were receiving an effective pain reliever caused the improvement.

The placebo effect is a real change in outcome produced by a participant's expectation of benefit, not by a chemical ingredient. Because the capsule was inert, belief is the best explanation.

From practice test 5 of our TEAS study guide (question 58). Original question, not an official exam item.

Correct answer: B. It is a dependent clause that begins with 'because' and leaves the thought unfinished.

The clause has a subject and a verb, but 'because' is a subordinating conjunction that makes the thought incomplete until an independent clause is added. The closest distractor is wrong because the clause clearly contains the verb 'was infected.'

From practice test 8 of our TEAS study guide (question 48). Original question, not an official exam item.

Correct answer: B. 0.45

Drop the percent sign and move the decimal point two places to the left. Starting with 45.0, this gives 0.45.

From practice test 6 of our TEAS study guide (question 54). Original question, not an official exam item.

Correct answer: A. Skim the passage first, read the questions, then scan or close read only as each question requires

Skimming first gives the passage's topic and organization and allows main idea questions to be answered immediately. Scanning and close reading are targeted follow-ups driven by the specific questions.

From practice test 7 of our TEAS study guide (question 46). Original question, not an official exam item.

Correct answer: B. Sweat gland releasing sweat through a duct onto the skin

Exocrine glands secrete their products through ducts onto an epithelial surface. Sweat glands are classic exocrine glands, whereas the thyroid, pancreatic islets, and adrenal medulla are endocrine glands that release hormones into the blood.

From practice test 6 of our TEAS study guide (question 106). Original question, not an official exam item.

Correct answer: D. Capillary colloid osmotic pressure (oncotic pressure)

Albumin is the principal plasma protein responsible for colloid osmotic pressure, which pulls water into the capillary. A decrease in albumin lowers this force directly; systolic, hydrostatic, and pulse pressures are governed by cardiac output and arterial resistance, not by the plasma protein concentration.

From practice test 5 of our TEAS study guide (question 53). Original question, not an official exam item.

Correct answer: B. Potassium's outermost electron is in a higher principal shell, placing it much farther from the nucleus than lithium's outer electron

Moving down a group adds a principal shell, so the outermost electron in potassium is in a shell farther from the nucleus; filled inner shells also shield it. More protons do not eliminate this effect, and neutrons do not expand an atom.

From practice test 2 of our TEAS study guide (question 37). Original question, not an official exam item.

Correct answer: D. Transcription occurs in the nucleus, and translation occurs in the cytoplasm.

In a eukaryotic cell, RNA polymerases synthesize mRNA in the nucleus, and cytoplasmic ribosomes then translate it. This location difference follows directly from the presence of a nuclear envelope.

From practice test 8 of our TEAS study guide (question 73). Original question, not an official exam item.

Correct answer: A. his or her

In formal English, 'everyone' is singular and requires a singular pronoun. The singular possessive 'his or her' agrees with it, while the plural 'their' is the common error.

From practice test 3 of our TEAS study guide (question 49). Original question, not an official exam item.

Correct answer: B. 0.125

Move the decimal point two places to the left and drop the percent sign, turning 12.5% into 0.125. Moving the decimal only one place would give 1.25, which equals 125%, not 12.5%.

From practice test 7 of our TEAS study guide (question 39). Original question, not an official exam item.

Correct answer: C. What does it literally say? What does it imply beyond the literal words? Why did the author word it in this particular way?

Close reading probes literal content, unstated implication, and the author's deliberate choice of wording. Grammatical labels, paragraph position, and synonym substitution locate facts rather than interpret meaning.

From practice test 4 of our TEAS study guide (question 142). Original question, not an official exam item.

Correct answer: C. Cushioning and binding organs while allowing flexibility

The description identifies areolar connective tissue, a loose connective tissue that cushions and binds organs. Nervous tissue conducts signals, adipose tissue stores triglycerides, and red bone marrow produces blood cells.

From practice test 6 of our TEAS study guide (question 166). Original question, not an official exam item.

Correct answer: D. 4.9 L/min

Cardiac output equals heart rate times stroke volume, so 70 beats/min times 70 mL/beat is 4,900 mL/min, or 4.9 L/min. The other values result from misplacing the decimal during conversion to liters.

From practice test 6 of our TEAS study guide (question 5). Original question, not an official exam item.

Correct answer: C. The superscript 131

In nuclide notation, the mass number is the superscript written to the upper left of the element symbol. The subscript 53 is the atomic number, not the mass number.

From practice test 7 of our TEAS study guide (question 125). Original question, not an official exam item.

Correct answer: D. The app may improve anatomy quiz performance for similar students under comparable conditions

This wording is appropriate because the sample included nursing students at one university studying anatomy. Statements about all students or all subjects go beyond the sample, and assuming the app cannot work elsewhere is also unsupported.

From practice test 5 of our TEAS study guide (question 86). Original question, not an official exam item.

Correct answer: A. The pharmacy confirmed its supply, and it's available for immediate delivery.

'Its' is the possessive form, so 'its supply' is correct; 'it's' is the contraction of 'it is,' so 'it's available' is correct. The distractors reverse these spellings.

From practice test 3 of our TEAS study guide (question 109). Original question, not an official exam item.

Correct answer: B. 0.45

Because percent means per hundred, 45% is 45/100, which is 0.45. Moving the decimal point two places to the left from 45.0 gives 0.45; moving it three places gives 0.045.

From practice test 4 of our TEAS study guide (question 42). Original question, not an official exam item.

Correct answer: C. In the first sentence or early in the opening paragraph

Expository passages usually announce the main idea early, often in the first sentence or the opening paragraph. A supporting example or a conclusion-only placement is not the standard expository pattern.

From practice test 7 of our TEAS study guide (question 97). Original question, not an official exam item.

Correct answer: A. Midsagittal (median) plane

A midsagittal or median plane passes exactly through the midline, producing equal left and right halves. Parasagittal planes are offset from the midline and produce unequal halves.

From practice test 4 of our TEAS study guide (question 167). Original question, not an official exam item.
