Practice Tests Academy (PTA) General Aptitude Assessment — Questions and Answers

Question 1: A paragraph reads: 'Muscle spindles detect changes in muscle length, while Golgi tendon organs (GTOs) respond to changes in muscle tension. Activation of GTOs causes autogenic inhibition, reducing the contraction of the agonist muscle.' Which word in this passage means 'self-generated inhibition of the same muscle'?

Activation
Autogenic inhibition (Correct answer)
Agonist
Tension

Correct answer: Autogenic inhibition

Autogenic inhibition refers to inhibition triggered within the same (auto = self) muscle via GTO activation.

Question 2: A 'minimal clinically important difference' (MCID) on an outcome measure is BEST described as:

Any change documented by the treating clinician
Any change that reaches statistical significance (p < 0.05)
The smallest change that is meaningful to the patient's daily function (Correct answer)
A change of at least 50% from the baseline score

Correct answer: The smallest change that is meaningful to the patient's daily function

The MCID represents the threshold of change that patients perceive as beneficial, distinguishing meaningful improvement from measurement noise.

Question 3: Which example is a run-on sentence?

The patient attended three sessions, and progress was noted.
The patient attended three sessions; progress was noted.
Progress was noted after three sessions.
The patient attended three sessions progress was noted. (Correct answer)

Correct answer: The patient attended three sessions progress was noted.

A run-on sentence fuses two independent clauses without any punctuation or conjunction to separate them.

Question 4: Which value appears most frequently in this data set: 3, 7, 3, 9, 5, 7, 3, 2?

9
3 (Correct answer)
7
2

Correct answer: 3

The mode is the value that appears most often; 3 appears three times, more than any other value.

Question 5: A clinic has 5 treatment rooms, 3 available PTAs, and 9 waiting patients. What is the maximum number of patients that can be treated simultaneously?

2
3 (Correct answer)
5
9

Correct answer: 3

Each patient requires one PTA; with only 3 PTAs available, no more than 3 patients can be treated at once.

Question 6: What does it mean to evaluate a source's credibility?

Checking if the source is recent
Credibility cannot be assessed
Assessing the author's expertise, the publication's reputation, and the evidence supporting claims (Correct answer)
Only looking at the source's length

Correct answer: Assessing the author's expertise, the publication's reputation, and the evidence supporting claims

Evaluating credibility involves checking the author's qualifications, the publisher's reputation, the evidence provided, potential biases, and corroboration from other sources.

Question 7: What is the primary role of surfactant in the lungs?

Reduce surface tension in alveoli to prevent collapse (Correct answer)
Stimulate bronchodilation during exercise
Filter inhaled pathogens before reaching alveoli
Transport oxygen across the alveolar membrane

Correct answer: Reduce surface tension in alveoli to prevent collapse

Pulmonary surfactant is a phospholipid mixture secreted by type II pneumocytes that reduces alveolar surface tension, preventing alveolar collapse (atelectasis).

Question 8: The Great Depression of the 1930s was triggered largely by which major event in 1929?

Bank robberies
World War I ending
Stock market crash (Correct answer)
A major drought

Correct answer: Stock market crash

The Great Depression was triggered primarily by the stock market crash of October 1929, known as 'Black Tuesday,' which led to widespread bank failures and unemployment.

Question 9: Given: 'If a patient is in pain, they should not perform high-intensity exercise.' Patient Lisa is performing high-intensity exercise. What can you conclude?

Lisa's pain level is unknown
Lisa is in pain
Lisa should stop exercising
Lisa is not in pain (Correct answer)

Correct answer: Lisa is not in pain

By modus tollens (contrapositive), if pain implies no high-intensity exercise, and Lisa IS doing high-intensity, then Lisa is not in pain.

Question 10: Which bony landmark is palpated to locate the greater sciatic notch region during a hip examination?

Anterior superior iliac spine (ASIS)
Pubic symphysis
Ischial tuberosity (Correct answer)
Greater trochanter

Correct answer: Ischial tuberosity

The ischial tuberosity is the bony prominence of the pelvis used as a landmark when locating structures near the greater sciatic notch.

Question 11: A PTA exam scenario describes a patient who is not following their home exercise program. The MOST appropriate PTA response is to:

Explore barriers to adherence and collaboratively modify the program with the patient (Correct answer)
Discharge the patient for failure to participate in their treatment plan
Document non-compliance in the chart and make no changes to the program
Report the patient's non-compliance directly to the insurance carrier

Correct answer: Explore barriers to adherence and collaboratively modify the program with the patient

Exploring barriers and collaborating on modifications reflects patient-centered care principles and supports long-term adherence.

Question 12: When a PTA exam question asks for the 'BEST' intervention, what does this imply about the answer choices?

There is only one medically possible answer
Multiple options may be partially correct, but one is most appropriate for the scenario (Correct answer)
All other options are completely wrong
You should choose the most complex or expensive treatment

Correct answer: Multiple options may be partially correct, but one is most appropriate for the scenario

'Best' questions require ranking answers by appropriateness for the specific patient context, not identifying the only valid option.

Question 13: A patient's pain scores over 7 sessions were: 7, 6, 8, 5, 6, 4, 6. What is the mode?

5
7
8
6 (Correct answer)

Correct answer: 6

The mode is 6 because it appears three times, more than any other value.

Question 14: Which surface landmark corresponds to the T7 vertebral level?

Inferior angle of the scapula (Correct answer)
Acromion process
Spine of the scapula
Superior angle of the scapula

Correct answer: Inferior angle of the scapula

The inferior angle of the scapula is a common landmark that aligns with the T7 (or T7-T8) vertebral level.

Question 15: Which president issued the Emancipation Proclamation in 1863, declaring enslaved people in Confederate states to be free?

Andrew Jackson
Abraham Lincoln (Correct answer)
George Washington
Ulysses S. Grant

Correct answer: Abraham Lincoln

President Abraham Lincoln issued the Emancipation Proclamation on January 1, 1863, as a wartime executive order during the Civil War.

Question 16: A rehab program cycles through three phases — Acute, Sub-acute, Functional — each lasting one week, then repeats. If Week 1 is Acute, what phase is the patient in during Week 8?

Acute
Discharged
Sub-acute (Correct answer)
Functional

Correct answer: Sub-acute

Week 8: (8−1) mod 3 = 1, mapping to position 2 in the cycle, which is Sub-acute.

Question 17: Which transition word best signals a contrast between two ideas in a clinical progress report?

Furthermore
Therefore
Additionally
However (Correct answer)

Correct answer: However

'However' signals contrast or opposition between ideas, while 'furthermore' and 'additionally' add supporting information.

Question 18: Which type of chemical reaction releases energy to the surroundings?

Anabolic reaction
Exothermic reaction (Correct answer)
Reduction reaction
Endothermic reaction

Correct answer: Exothermic reaction

Exothermic reactions release energy (usually as heat) to the surroundings because the products have lower energy than the reactants.

Question 19: An article explains: 'Open kinetic chain (OKC) exercises allow the distal segment to move freely, isolating individual muscles. Closed kinetic chain (CKC) exercises fix the distal segment, promoting co-contraction and joint stabilization.' A patient performs a seated knee extension machine exercise. According to the passage, how is this exercise classified?

Open kinetic chain because it involves the knee joint
Closed kinetic chain because the patient is seated
Closed kinetic chain because it strengthens the quadriceps
Open kinetic chain because the distal segment (foot) moves freely (Correct answer)

Correct answer: Open kinetic chain because the distal segment (foot) moves freely

In a seated knee extension, the foot (distal segment) moves freely, making it an open kinetic chain exercise.

Question 20: When a test-taker spends too long on a difficult question during a timed PTA exam, the BEST strategy is to:

Ask the proctor for clarification on the clinical terms
Skip all remaining difficult questions and focus only on easy ones
Stay on the question until certain of the correct answer
Mark it and return after completing easier questions first (Correct answer)

Correct answer: Mark it and return after completing easier questions first

Flagging and returning to difficult questions preserves time for questions where you can confidently earn points.

Question 21: What is the difference between correlation and causation?

Causation does not require evidence
Correlation is stronger than causation
Correlation shows two things are related; causation proves one directly causes the other (Correct answer)
They mean the same thing

Correct answer: Correlation shows two things are related; causation proves one directly causes the other

Correlation indicates a statistical relationship between variables, but causation requires evidence that one variable directly produces a change in the other.

Question 22: In the sentence 'The treatment had a positive affect on the patient,' what is the error?

There is no error in the sentence.
'positive' should be 'positively'
'affect' should be 'effect' (Correct answer)
'treatment' should be 'treatments'

Correct answer: 'affect' should be 'effect'

'Effect' is used as a noun meaning result or outcome, while 'affect' is typically used as a verb meaning to influence.

Question 23: An excerpt reads: 'Edema formation follows Starling's Law: fluid moves from capillaries into interstitial space when capillary hydrostatic pressure exceeds plasma oncotic pressure. Elevation and compression counteract this by reducing hydrostatic pressure and enhancing lymphatic return.' Based on this passage, how does elevation reduce edema?

It increases metabolic activity in the limb
It reduces capillary hydrostatic pressure (Correct answer)
It increases plasma oncotic pressure directly
It eliminates lymphatic vessels

Correct answer: It reduces capillary hydrostatic pressure

The passage states elevation counteracts edema by reducing hydrostatic pressure, one of the forces driving fluid into interstitial space.

Question 24: What is the difference between their, there, and they're?

Their = possessive, there = location/existence, they're = they are (Correct answer)
They all mean the same thing
There is possessive
Their is a location word

Correct answer: Their = possessive, there = location/existence, they're = they are

'Their' shows possession, 'there' indicates location or existence, and 'they're' is a contraction of 'they are'.

Question 25: A PTA is asked to perform a specialized technique that exceeds their current level of competency. The MOST ethical response is to:

Attempt the technique and seek guidance only if a problem arises
Ask a co-worker to perform it while taking responsibility in documentation
Perform the technique when unsupervised to avoid embarrassment
Decline and explain the competency concern to the supervising PT (Correct answer)

Correct answer: Decline and explain the competency concern to the supervising PT

Practicing beyond one's competence endangers the patient; the ethical obligation is to disclose the limitation and decline until competency is established.

Question 26: The APTA Code of Ethics is primarily intended to:

Provide legal defense for PTAs in malpractice cases
Set reimbursement rates for physical therapy services
Guide PTAs and PTs in ethical professional conduct and decision-making (Correct answer)
Establish state licensure examination requirements

Correct answer: Guide PTAs and PTs in ethical professional conduct and decision-making

The APTA Code of Ethics outlines the core values and ethical obligations that guide professional behavior for physical therapists and PTAs.

Question 27: In context, what does 'pragmatic' mean: 'She took a pragmatic approach and focused on what would actually work'?

Idealistic and visionary
Aggressive and forceful
Dealing with things practically (Correct answer)
Emotional and passionate

Correct answer: Dealing with things practically

Pragmatic means dealing with things sensibly and realistically based on practical rather than theoretical considerations.

Question 28: In the context of muscle physiology, what is the 'all-or-none principle'?

The entire muscle group activates before a single fiber contracts
A muscle either contracts maximally or not at all when stimulated above threshold
All muscle fibers in a muscle contract simultaneously at maximum force
A muscle fiber either produces full tension or no tension when stimulated above its threshold (Correct answer)

Correct answer: A muscle fiber either produces full tension or no tension when stimulated above its threshold

The all-or-none principle states that a single muscle fiber, when stimulated above its threshold, produces its maximal contraction — it cannot produce a partial response.

Question 29: In times of rising prices, what impact does using the historical cost concept have on a company's asset values and profit?

Asset values understated and profit overstated (Correct answer)
Asset values and profit both understated
Asset values and profit both overstated
Asset values overstated and profit understated

Correct answer: Asset values understated and profit overstated

Under the historical cost concept, assets are recorded at their original purchase price. In times of rising prices (inflation), this means the reported asset values will be lower than their current market value, leading to understatement. Consequently, depreciation charges based on these lower historical costs will be smaller, resulting in higher reported profits than if assets were valued at current replacement costs.
