Question 3: What is the definition of freezing point?

• Point at which a liquid turns to a solid (Correct answer)
• Point at which a gas turns to a solid
• Point at which a liquid turns to a gas
• Point at which a gas turns to a liquid.

Correct answer: Point at which a liquid turns to a solid

Freezing point is the specific temperature at which a substance transitions from its liquid state to its solid state. At this temperature, the kinetic energy of the molecules decreases enough for them to arrange into a fixed, ordered structure. This is the inverse process of melting.

Question 4: A book store contains 75,972 books, divided in three sections: Science, Business, and Math. The science section represents 1\/3 of the total books. Of the remaining books, 75% are business. How many books are in the math section?

• 25324
• 37986
• 12,662 (Correct answer)
• 50,648

Correct answer: 12,662

First, calculate the number of science books: (1/3) * 75,972 = 25,324 books. Subtract these from the total to find the remaining books: 75,972 - 25,324 = 50,648 books. Next, calculate the number of business books: 75% of 50,648 = 0.75 * 50,648 = 37,986 books. Finally, subtract the business books from the remaining books to find the math books: 50,648 - 37,986 = 12,662 books.

Question 5: The acceleration due to gravity on Earth is -9.8 m/s². Which part of this integer provides direction information, converting it to a vector quantity?

• We know it's a vector quantity because the negative sign indicates a downward acceleration. (Correct answer)
• Because the seconds are squared in the units, we know it's a vector quantity.
• The negative sign indicates that the acceleration is upward, therefore we know it's a vector quantity.
• Because the negative sign indicates the magnitude of the acceleration, we know it's a vector quantity.

Correct answer: We know it's a vector quantity because the negative sign indicates a downward acceleration.

A vector quantity is a physical quantity that has both magnitude (size) and direction. The value -9.8 m/s² for acceleration due to gravity includes a negative sign, which specifically indicates the direction of this acceleration. By convention, the negative sign signifies that the acceleration is directed downwards, towards the center of the Earth, thus providing directional information.

Question 6: A woman has a mass of 50 kg on the moon. What is her mass on Earth?

• 25 kg

• 0 kg

Correct answer: 50 kg

Mass is a fundamental measure of the amount of matter in an object and is an intrinsic property that remains constant regardless of location or gravitational pull. While an object's weight changes with gravity (e.g., less on the Moon), its mass of 50 kg will be the same on Earth as it is on the Moon.

Question 7: Ben walks 25 miles from home to work. If he walks the first 5 miles in 1 hour, the second 5 miles in 1.4 hours, the third 5 miles in 1.7 hours and the last 5 miles in 1.8 hours, how long will it take him to complete the 25 mile walking distance? (Enter numeric value only. If rounding is required, round to the nearest tenth).

• 6 hours
• 5.9 hours (Correct answer)
• 5 hours
• 10 hours

Correct answer: 5.9 hours

To find the total time Ben will take, sum the time spent on each segment of his walk. Add the times for the first, second, third, and last 5-mile segments: 1 hour + 1.4 hours + 1.7 hours + 1.8 hours. The sum is 5.9 hours. Since the problem asks to round to the nearest tenth if required, 5.9 hours is already in the correct format.

Question 18: Which of the following does the diaphragm perform during exhalation?

• Relaxes and lifts (Correct answer)
• Relaxes and lowers
• Contracts and lifts
• Does not move

Correct answer: Relaxes and lifts

During exhalation, the diaphragm relaxes and moves upwards, or lifts, into the thoracic cavity. This upward movement decreases the volume of the chest cavity, which in turn increases the pressure within the lungs, forcing air out. In contrast, during inhalation, the diaphragm contracts and flattens.

Question 19: Which of the following states of matter has a definite volume?

• Gas and solid
• Gas and liquid
• Liquid and solid (Correct answer)
• Gas, liquid, and volume

Correct answer: Liquid and solid

Solids have a definite shape and a definite volume because their particles are tightly packed in fixed positions. Liquids have a definite volume but take the shape of their container, as their particles are close but can move past each other. Gases, however, have neither a definite shape nor a definite volume, expanding to fill any container.

Question 20: What do you call substances that cannot be broken down into simpler forms of matter?

Question 45: Which of the following causes cramps during strenuous exercise?

• Pyruvate
• Protein
• Lactate (Correct answer)
• Glucose

Correct answer: Lactate

During strenuous exercise, when oxygen supply to muscles is insufficient, cells switch to anaerobic respiration, producing lactate (lactic acid) as a byproduct. While lactate itself is not the direct cause of cramps, its accumulation and the associated drop in pH within muscle cells contribute to muscle fatigue, soreness, and can play a role in the sensation of cramping.

Question 46: My dearest friend was in a terrible automobile accident last Sunday night that left him hurt ____________.

• baddest
• badly (Correct answer)
• bad
• worst

Correct answer: badly

'Badly' is an adverb that correctly modifies the verb 'hurt,' describing the extent or manner of the injury. 'Bad' is an adjective and should not be used to modify a verb. Therefore, 'hurt badly' is the grammatically correct way to express the severity of the injury.

Question 52: Why does a helium balloon rise in air?

• It is lighter than air (Correct answer)
• It repels gravity
• It has magnetic properties
• It heats up the air around it

Correct answer: It is lighter than air

A helium balloon rises because helium gas is less dense than the surrounding air. According to Archimedes' principle, an object immersed in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced. Since the helium balloon displaces a volume of air that weighs more than the balloon itself (including the helium), it experiences a net upward force, causing it to rise.

Question 53: What's the connection between sarcomeres, myofibrils, and muscle cells?

• Muscle cells include myofibrils, which are composed of sarcomeres. (Correct answer)
• Sarcomeres include muscle cells, which are composed of sarcomeres.
• Sarcomeres are found in muscle cells, which are made up of myofibrils.
• Sarcomeres, which are made up of muscle cells, are found in myofibrils.

Correct answer: Muscle cells include myofibrils, which are composed of sarcomeres.

Muscle cells, also known as muscle fibers, are the basic units of muscle tissue. Within these cells are numerous rod-like structures called myofibrils, which are responsible for muscle contraction. Myofibrils, in turn, are composed of repeating functional units called sarcomeres, which are the smallest contractile units of a muscle.

Question 54: In the formula H2O, the subscript 2 indicates:

• she and me
• her and I
• she and I
• her and me (Correct answer)

Correct answer: her and me

'Her and me' is correct because both pronouns are objects of the verb 'asked.' Use object pronouns (me, her, him) when the pronoun receives the action. You can test this by removing one pronoun: 'asked her' and 'asked me' both sound correct.

Question 57: What does the term 'dermatology' mean?

• Study of the heart
• Study of the skin (Correct answer)
• Study of the blood
• Study of the bones

Correct answer: Study of the skin

Correct answer: Nucleic acids

Nucleic acids, specifically DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), are the macromolecules responsible for carrying genetic information. DNA stores the complete hereditary instructions for an organism's development and function, while RNA plays a crucial role in expressing these instructions to build proteins.

Question 59: The change in state from a gas to liquid is called what?

• Evaporation
• Condensation (Correct answer)
• Vaporization
• Disposition

Correct answer: Condensation

Condensation is the process where a substance changes its physical state from a gas to a liquid. This occurs when gas particles lose enough thermal energy to slow down and come closer together, allowing intermolecular forces to pull them into a liquid form. A common example is water vapor turning into liquid water droplets, forming clouds or dew.

Question 60: Which strategy is best when encountering an unfamiliar word?

• Ignore it if it’s not a noun
• Look at surrounding words for clues (Correct answer)
• Guess its meaning randomly
• Skip the word entirely

Correct answer: Look at surrounding words for clues

When encountering an unfamiliar word, the most effective strategy is to use context clues by looking at the surrounding words, sentences, and paragraphs. These clues often provide definitions, synonyms, antonyms, or examples that help readers deduce the word's meaning without interrupting their reading flow. This approach enhances comprehension and vocabulary development.

Question 61: What is called by the release of prolactin during breastfeeding?

• Gene regulation
• Negative feedback
• Positive feedback (Correct answer)
• Cell permeability

Correct answer: Positive feedback

The release of prolactin during breastfeeding is a classic example of a positive feedback loop. When an infant suckles, sensory nerves in the nipple send signals to the hypothalamus, which stimulates the anterior pituitary to release prolactin. Prolactin then promotes milk production, and increased suckling leads to even more prolactin release, amplifying the response until the stimulus is removed.

Question 62: During final exams 172 students visited the math lab in total. If 4 out of 11 were male what is the percentage of female students who visited the math lab? (Round to the nearest tenth). a. 63.6%\t

• 62.5%
• 63.6% (Correct answer)
• 63%
• 63.64%

Correct answer: 63.6%

If 4 out of 11 students were male, then the remaining students are female. This means 11 - 4 = 7 out of 11 students were female. To find the percentage of female students, divide the number of female students by the total number of students in the ratio (7/11) and multiply by 100%. This calculation yields approximately 63.636%, which rounds to 63.6% to the nearest tenth.

Question 63: Two atoms of the same element that have the same number of protons but different numbers of neutrons are called:

• Allotropes
• Isomers
• Isotopes (Correct answer)
• Ions

Question 73: All of the following factors influence the pace of a chemical reaction except?

• Amount of mass lost (Correct answer)
• Presence of catalysts
• Temperature
• Surface area

Correct answer: Amount of mass lost

The pace or rate of a chemical reaction is influenced by factors such as the presence of catalysts, the surface area of reactants, and the temperature. The 'amount of mass lost' is not a factor influencing the reaction rate; rather, it would be a measurement of the extent of a reaction, and mass is conserved in chemical reactions.

Question 74: What happens to the current in a circuit if the resistance increases while voltage stays the same?

• Current decreases (Correct answer)
• Current remains unchanged
• Voltage decreases
• Current increases

Correct answer: Current decreases

According to Ohm's Law, which states V = IR (Voltage = Current x Resistance), current and resistance are inversely proportional when voltage is constant. Therefore, if the resistance in a circuit increases while the voltage remains the same, the current flowing through the circuit must decrease to maintain the equality.

• 5\/10
• 7\/20 (Correct answer)
• 1\/2
• 5\/10

Correct answer: 7\/20

To convert a percentage to a fraction, divide the percentage value by 100. So, 35% becomes 35/100. Then, simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 5, yielding the simplified fraction 7/20.

Question 76: Which of these sentences contains an active verb tense?

• The spaghetti was quickly devoured by the hungry children.
• The lawyer presented his case to the jury. (Correct answer)
• The woman was given an engagement ring by her boyfriend.
• The boy was rewarded with a trophy for his win.

Correct answer: The lawyer presented his case to the jury.

An active verb tense means the subject of the sentence performs the action. In option B, 'the lawyer' is the subject, and 'presented' is the verb, indicating that the lawyer is actively performing the action of presenting. The other options use passive voice, where the subject receives the action (e.g., 'was given,' 'was rewarded,' 'was devoured') rather than performing it.

Question 77: A student observes a plant bending toward a light source. What is the best explanation for this behavior?

• Gravitropism
• Photosynthesis
• Phototropism (Correct answer)
• Respiration

Correct answer: Phototropism

• The patient's chart was missing two pages. (Correct answer)
• The patients' chart was missing two pages.

Correct answer: The patient's chart was missing two pages.

When showing possession for a singular noun, place the apostrophe before the 's.' Since the chart belongs to one patient, 'patient's' is correct. 'Patients'' would indicate possession belonging to multiple patients.

Question 80: Which sentence contains a dangling modifier?

• Having finished her charting, she clocked out for the night.
• Running down the hallway, the nurse reached the patient in time.
• Exhausted from the long shift, the break room offered some relief. (Correct answer)
• After reviewing the labs, the doctor ordered a new medication.

Correct answer: Exhausted from the long shift, the break room offered some relief.

In 'Exhausted from the long shift, the break room offered some relief,' the modifier 'exhausted from the long shift' incorrectly modifies 'break room' rather than a person. A break room cannot be exhausted. The sentence should read: 'Exhausted from the long shift, she found some relief in the break room.'

Question 81: A graphic in a passage shows infection rates rising over five years. This visual most directly supports a main idea about:

• The cost of treatment
• Staff scheduling
• Hospital architecture

Question 88: Which transition best completes this sentence correctly? Sarah did not realize until after she arrived in New York that she had left her ball gown at home; ____, she was fortunate enough to find a shop that rented them by the evening.

• after all
• however (Correct answer)
• because
• while

Correct answer: however

The sentence presents a contrast: Sarah initially faced a problem (leaving her gown) but then experienced a fortunate resolution (finding a rental shop). The conjunctive adverb 'however' is used to introduce a statement that contrasts with or qualifies the preceding statement. It perfectly signals this shift from a negative situation to a positive outcome, making it the most appropriate transition word.

Question 89: Convert 3\/5 to a decimal.

• 0.06
• 0.6 (Correct answer)
• 3.50
• 1.6

Correct answer: 0.6

To convert a fraction to a decimal, divide the numerator by the denominator. For 3/5, divide 3 by 5. Performing this division, 3 ÷ 5 equals 0.6.

Question 94: After the storm, telephone poles ____________ all over the street.

• were lying (Correct answer)
• lied
• laid
• were laying

Correct answer: were lying

The verb 'to lie' (meaning to recline or rest) is intransitive, meaning it does not take a direct object. Its present participle is 'lying.' The sentence describes telephone poles resting on the street. 'To lay' (meaning to place something down) is transitive and requires a direct object, while 'lied' is the past tense of 'to lie' (to tell an untruth).

Question 95: A mutation that changes a single nucleotide base in DNA is called what?

• It stays the same
• It quadruples (Correct answer)
• It doubles

Correct answer: It quadruples

Kinetic energy (KE) is calculated using the formula KE = 0.5 * m * v², where m is mass and v is velocity. If you double the velocity (2v), the new kinetic energy becomes 0.5 * m * (2v)² = 0.5 * m * 4v² = 4 * (0.5 * m * v²). Therefore, doubling the velocity quadruples the kinetic energy.

Question 196: Multiply 1.25 x 2.0

• 0.250
• 25.0
• 250.0
• 2.50 (Correct answer)

Correct answer: 2.50

To multiply decimals, perform the multiplication as you would with whole numbers, ignoring the decimal points initially. Then, count the total number of decimal places in the numbers being multiplied and place the decimal point in the product so it has that same total number of decimal places. For 1.25 x 2.0, multiply 125 by 2 to get 250. Since 1.25 has two decimal places and 2.0 has one, the product needs three decimal places, resulting in 2.500, which simplifies to 2.50.

Question 197: Which word means most nearly the same as the underlined word in this sentence? “During the bypass surgery, the surgeon had to locate the anterior veins first before she could reach the heart itself.”

• Aft
• Posterior
• Frontal (Correct answer)
• Exterior

Correct answer: Frontal

In anatomy, 'anterior' refers to the front of the body or a body part. It describes a position closer to the front surface. Therefore, 'frontal' is the most accurate synonym, indicating the front aspect or direction.

Question 198: 45.\t5 1\/2 divide by 2 1\/2

• 2 1\/5 (Correct answer)
• 2.0
• 21
• 2 3\/4

Correct answer: 2 1\/5

To divide mixed numbers, first convert them into improper fractions. 5 1/2 becomes 11/2, and 2 1/2 becomes 5/2. Then, multiply the first fraction by the reciprocal of the second fraction: (11/2) * (2/5). The 2s cancel out, leaving 11/5. Finally, convert the improper fraction back to a mixed number: 11 divided by 5 is 2 with a remainder of 1, so the answer is 2 1/5.

Question 199: In an exothermic reaction, what happens to energy?

• Energy is absorbed from the surroundings
• Energy remains unchanged
• Energy is converted entirely to matter
• Energy is released to the surroundings (Correct answer)

• Diapedesis (Correct answer)
• Phagocytosis
• Pinocytosis
• Chemotaxis

Correct answer: Diapedesis

Diapedesis (also called extravasation) is the process by which leukocytes squeeze through the walls of capillaries to reach the site of infection or injury in surrounding tissues.

Question 202: Which word is a context clue that signals a contrast in a sentence?

• Similarly
• Because
• However (Correct answer)
• Therefore

Correct answer: However

'However' introduces an idea that contrasts with what came before.

Question 203: If a specific reversible process reached equilibrium, what would happen if more reactants were added?

• The equilibrium would change in favor of the formation of additional products. (Correct answer)
• The reaction would heat up
• Nothing, because the reaction has reached equilibrium.
• The equilibrium position would move, resulting in the formation of more reactants.

Correct answer: The equilibrium would change in favor of the formation of additional products.

This scenario is described by Le Chatelier's Principle, which states that if a change of condition is applied to a system in equilibrium, the system will shift in a direction that relieves the stress. Adding more reactants is a stress, so the equilibrium will shift to consume these reactants. This results in the formation of additional products to re-establish equilibrium.

Question 204: A passage compares two treatments by listing similarities and differences. What text structure is this?

• Chronological order
• Cause and effect
• Description
• Compare and contrast (Correct answer)

Correct answer: Compare and contrast

The prefix 'salpingo-' is derived from the Greek word 'salpinx,' meaning 'trumpet' or 'tube.' In medical terminology, it specifically refers to a tube, most commonly the fallopian tube (e.g., salpingectomy for removal of a fallopian tube) or sometimes the Eustachian tube.

Question 207: The average speed of a high velocity train is 200 kilometers per hour. The distance between Paris and Naples is 7,346 km (1 mile = 1.609 km). How long will the trip take? (Round to the nearest whole number).

• 37 hours (Correct answer)
• 36.73 hours
• 38 hours
• 3.8 hours

Correct answer: 37 hours

To find the time the trip will take, use the formula Time = Distance / Speed. The distance is 7,346 km and the speed is 200 km/h. Divide 7,346 by 200, which equals 36.73 hours. Rounding 36.73 to the nearest whole number gives 37 hours. The information about miles to kilometers is extraneous for this calculation.

Question 208: Dr. Henry has his nursing staff line up at 4:30PM for the annual meeting. What would that be in military time?

• 0430
• 2030
• 1630 (Correct answer)
• 4030

Correct answer: 1630

To convert regular time to military time for any hour in the afternoon (P.M.), you add 12 to the hour. For 4:30 P.M., add 12 to 4, which equals 16. The minutes remain the same. Therefore, 4:30 P.M. in military time is 1630.

Question 209: Which of the following best defines a supporting detail?

• Repeated information
• Examples or facts that support the main idea (Correct answer)
• Unrelated facts

Correct answer: Examples or facts that support the main idea

A supporting detail is a specific piece of information, such as an example, fact, statistic, or description, that serves to elaborate on and provide evidence for the main idea of a passage. These details strengthen the author's argument or explanation, making the central point more understandable, credible, and convincing. Without them, the main idea would lack substantiation.

Question 210: How many pounds are 10 kilograms?

• 150 pounds
• 2.5 pounds
• 22 pounds (Correct answer)
• 45 pounds

Correct answer: 22 pounds

To convert kilograms to pounds, use the conversion factor that 1 kilogram is approximately equal to 2.20462 pounds. Therefore, 10 kilograms * 2.20462 pounds/kilogram equals 22.0462 pounds. Rounding this to the nearest whole number gives 22 pounds.

Question 211: 3 gallons is equal to how many ounces?

• 384 ounces (Correct answer)
• 250 ounces
• 3000 ounces
• 300 ounces

Correct answer: 384 ounces

To convert gallons to ounces, you need to know that 1 gallon is equal to 128 ounces (since 1 gallon = 4 quarts, 1 quart = 2 pints, and 1 pint = 16 ounces, so 4 * 2 * 16 = 128 ounces). Therefore, to find how many ounces are in 3 gallons, you multiply 3 by 128. This calculation results in 384 ounces.

Question 212: What is the regular time for the given military time: 0507?

• 5:07 A.M (Correct answer)

• Ask another nurse to administer it instead
• Administer half the dose as a compromise

Correct answer: Clarify the order with the prescribing physician before administering

Nurses have an independent duty to question orders that appear unsafe. A dose 5-25 times the standard requires clarification before administration.

Question 228: It is possible for an object to show two different types of motion at the same time.

• Project Motion (Correct answer)
• Scalar quantity
• Force
• Acceleration

Correct answer: Project Motion

Projectile motion describes the path an object takes when launched into the air and is only subject to gravity. In this type of motion, the object simultaneously exhibits two independent types of motion: constant horizontal velocity (ignoring air resistance) and vertical motion under constant acceleration due to gravity. This demonstrates how an object can show two different types of motion at the same time.

A good summary captures the central idea and the most important supporting points concisely.

Question 281: In a medical journal abstract: 'This randomized controlled trial (n=500) found that early mobilization after hip replacement surgery reduced hospital stays by an average of 1.8 days (p<0.001) compared to standard care protocols.' What does 'p<0.001' indicate to the reader?

• The sample size was too small for valid conclusions
• The intervention reduced costs by 0.1%
• The results are not clinically important
• The finding is statistically significant and unlikely due to chance (Correct answer)

Correct answer: The finding is statistically significant and unlikely due to chance

A p-value less than 0.001 indicates very high statistical significance, meaning there is less than a 0.1% probability the results occurred by chance.

Question 282: What is the best definition of the word obstinate?

• Angry
• Stubborn (Correct answer)
• Careless
• Passive

Correct answer: Stubborn

The word 'obstinate' describes someone who is stubbornly refusing to change one's opinion or chosen course of action, despite attempts to persuade them. It implies a strong resistance to persuasion or change, often due to a fixed mindset. Therefore, 'stubborn' is the most direct and accurate synonym.

Question 283: A passage presents two sides of an argument and then favors one. What is the author most likely trying to do?

• Persuade the reader (Correct answer)
• Provide a recipe
• List random facts
• Tell a fictional story

Correct answer: Persuade the reader

Presenting sides and favoring one is a persuasive technique meant to convince the reader.

Question 284: What is the molarity of an aqueous solution containing 0.40 moles of sugar in 5 liters of water?

• 0.08 M (Correct answer)
• 0.04 M
• 400.0 M
• 8.0 M

Correct answer: 0.08 M

Molarity (M) is defined as the number of moles of solute per liter of solution. To calculate the molarity, you divide the given moles of sugar (0.40 moles) by the volume of water in liters (5 liters). Therefore, 0.40 moles / 5 L = 0.08 M.

Question 285: At a speed of 8 m/s, a 0.5 kg object suspended from a 0.75 m rope circles a center point. How much stress does the string feel in the absence of gravity?

• 42.7 N (Correct answer)
• 5.3 N
• 66.7 N
• 80.1 N

Correct answer: 42.7 N

In the absence of gravity, the stress on the string is entirely due to the centripetal force required to keep the object moving in a circle. The centripetal force (Fc) is calculated using the formula Fc = mv²/r, where m = 0.5 kg, v = 8 m/s, and r = 0.75 m. Plugging in these values gives Fc = (0.5 * 8²) / 0.75 = 32 / 0.75 ≈ 42.67 N.

Question 286: Which of the following correctly orders the levels of biological organization from smallest to largest?

• Organ system, organ, tissue, cell
• Organ, tissue, cell, organ system
• Tissue, cell, organ system, organ
• Cell, tissue, organ, organ system (Correct answer)

Correct answer: Cell, tissue, organ, organ system

Cells form tissues, tissues form organs, and organs form organ systems.

Question 287: Ligaments connect which two structures?

• Muscle to muscle
• Muscle to bone
• Bone to bone (Correct answer)
• Tendon to bone

Correct answer: Bone to bone

Ligaments are strong, fibrous bands of connective tissue that primarily connect bones to other bones. Their main function is to stabilize joints, limit excessive movement, and prevent dislocations. In contrast, tendons connect muscles to bones.

Question 288: Joy learned a new song to play on the guitar, and it sounds ____________.

• Lovely (Correct answer)
• Beautifully
• More beautiful
• Loveliest

Correct answer: Lovely

The verb 'sounds' in this sentence is a linking verb, which connects the subject ('it,' referring to the song) to a word that describes or renames the subject. Linking verbs should be followed by an adjective, not an adverb. 'Lovely' is an adjective that correctly describes the quality of the song.

Question 289: Citric acid is found in lemon juice. Which of the following pH levels is most likely for lemon juice?

• 15
• 2 (Correct answer)
• 7
• 9

Correct answer: 2

Citric acid is a common acid found in citrus fruits like lemons. Acids are characterized by a pH value less than 7, with stronger acids having lower pH values. Lemon juice is known to be quite acidic, making a pH of 2 the most appropriate choice among the given options for a highly acidic substance.
