- 8.5 kilograms (Correct answer)
- 0.8 kilograms
Correct answer: 8.5 kilograms
To convert grams to kilograms, you need to know that 1 kilogram (kg) is equal to 1,000 grams (g). Therefore, to convert 8,500 grams to kilograms, you divide 8,500 by 1,000. This calculation results in 8.5 kilograms.
Question 35: Why is it important to identify bias in a passage?
- To evaluate the trustworthiness of the content (Correct answer)
- To find the authorâs name
- To understand emotional words
- To memorize the content
Correct answer: To evaluate the trustworthiness of the content
Identifying bias in a passage is critical because it reveals the author's potential leanings, prejudices, or one-sided perspectives, which can influence the information presented. Recognizing bias allows readers to critically evaluate the content's objectivity, question its reliability, and determine the trustworthiness of the information. This critical assessment is essential for forming well-informed and balanced opinions.
Question 36: A fresh egg will float in waterâŚ
- It will not float in any circumstance
- When the water is cold
- When salt is added to the water (Correct answer)
- Always
Correct answer: When salt is added to the water
An object floats when its density is less than the density of the fluid it displaces. Adding salt to water increases the water's density. If enough salt is dissolved, the saltwater solution becomes denser than the egg, causing the egg to float.
Question 37: Evaluating the outcome of an intervention is important because it:
- Ends the nursing process
- Determines whether goals were met and if changes are needed (Correct answer)
- Replaces assessment
- Is optional
Correct answer: Determines whether goals were met and if changes are needed
Evaluation checks goal achievement and guides adjustments.
Question 38: The process by which white blood cells move out of capillaries into surrounding tissue is called:
- Chemotaxis
- Pinocytosis
- Diapedesis (Correct answer)
- Phagocytosis
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 39: Covert the following military hours to civilian hours: 20:30
- 10:30 AM
- 9:30 AM
- 2:30 PM
- 8:30 PM (Correct answer)
Correct answer: 8:30 PM
To convert military time (24-hour format) to civilian time (12-hour format), if the hour is 13 or greater, subtract 12 from the hour and append 'PM'. For 20:30, subtracting 12 from 20 gives 8, so the civilian time is 8:30 PM.
Question 40: When hydrochloric acid (HCl) reacts with sodium hydroxide (NaOH) in a neutralization reaction, what are the products?
- Hâ gas and NaCl
- NaOH and Clâ
- Na metal and HClO

Question 41: What is the pH of a solution with a hydrogen ion concentration [H+] of 1 x 10^-4 M?
- 4 (Correct answer)
- 2
- 10
- 14
Correct answer: 4
pH = -log[H+] = -log(1 x 10^-4) = 4. This solution is acidic since the pH is below 7.
Question 42: In a military hospital, a nurse's shift runs from 1400 to 2100. When does the nurse start and finish her shift?
- 2 pm to 9 pm (Correct answer)
- 3 pm to 10 pm
- 3am to 8 pm
- 10 am to 3 pm
Correct answer: 2 pm to 9 pm
To convert military time to civilian time, subtract 12 from any hour greater than 12 and designate it as PM. Therefore, 1400 becomes 2 PM (14 - 12 = 2), and 2100 becomes 9 PM (21 - 12 = 9), meaning the nurse's shift is from 2 PM to 9 PM.
Question 43: What is the best way to define "predispose"?
- To make susceptible (Correct answer)
- To be cautious of bias

- Punctuation marks
- The length of the sentence
Correct answer: Words like 'however' or 'unlike'
Words like 'however,' 'unlike,' 'but,' 'in contrast,' or 'on the other hand' are crucial contrast clues that help identify the meaning of an unfamiliar word. These signal words indicate that the information following them will present an opposite or different idea from what was previously stated. By understanding this opposition, readers can infer the meaning of the unknown term.
Question 47: Which of the following causes cramps during strenuous exercise?
- Pyruvate
- Protein
- Glucose
- Lactate (Correct answer)
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 48: A passage is organized around a difficulty and a recommended fix. This structure is called:

Question 53: Brian ___________ up ten minutes after his alarm was supposed to go off.
- awakened
- awoke
- woken
- woke (Correct answer)
Correct answer: woke
'Woke' is the simple past tense of the verb 'to wake,' which is appropriate for a completed action in the past. The phrasal verb 'woke up' is a common and natural way to express this. 'Woken' is the past participle and requires an auxiliary verb (e.g., 'had woken'). 'Awakened' is also correct but 'woke' is more common in this context.
Question 54: 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).
- 5 hours
- 10 hours
- 5.9 hours (Correct answer)
- 6 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 55: If a cell is placed in a hypertonic solution, what will most likely happen to the cell?
- The cell will swell
- There will be no change
- The cell will burst
- The cell will shrink (Correct answer)
Correct answer: The cell will shrink
A hypertonic solution has a higher solute concentration outside the cell than inside. Due to osmosis, water will move from an area of higher water concentration (inside the cell) to an area of lower water concentration (outside the cell) to equalize the solute concentration, causing the cell to lose water and shrink.
Question 56: Which of these sentences contains a dependent clause?
- She told me she was hungry but wouldnât eat more.
- She is hungry but sheâs not going to eat.
- She said she is feeling hungry, but she is not going to eat.
- Although she is hungry, she is not going to eat. (Correct answer)
Correct answer: Although she is hungry, she is not going to eat.
A dependent clause contains a subject and a verb but cannot stand alone as a complete sentence because it begins with a subordinating conjunction. In option B, 'Although she is hungry' is a dependent clause, introduced by the subordinating conjunction 'although,' which makes it reliant on the independent clause 'she is not going to eat' for complete meaning.
Question 57: How many valence electrons does an oxygen atom (atomic number 8) have?

- A battery powers a toy car
- A ball stops due to friction
- A book falls off a table
- Two skaters push off each other and roll away (Correct answer)
Correct answer: Two skaters push off each other and roll away
The law of conservation of momentum states that in a closed system, the total momentum remains constant. When two skaters push off each other, they exert equal and opposite forces (Newton's Third Law), resulting in equal and opposite changes in their individual momenta, but the total momentum of the two-skater system before and after the push remains conserved.
Question 92: Which sentence is grammatically correct?
- Kevin prays at St. Maryâs Church fervently for his sisterâs salvation.
- None of these are grammatically correct.
- Kevin prays for his sisterâs salvation at St. Maryâs Church, fervently.
- Kevin prays fervently at St. Maryâs Church for his sisterâs salvation. (Correct answer)
Correct answer: Kevin prays fervently at St. Maryâs Church for his sisterâs salvation.
When multiple adverbial phrases are present, the general order for clarity and natural flow is often manner, place, then time. In this sentence, 'fervently' describes *how* Kevin prays (manner), 'at St. Maryâs Church' describes *where* he prays (place), and 'for his sisterâs salvation' describes *why* he prays (purpose). Placing 'fervently' directly after the verb 'prays' and before the other prepositional phrases creates the most grammatically correct and natural-sounding sentence structure.
Question 93: Which organelle is primarily responsible for ATP production in the cell?

Correct answer: Cautionary and concerned
The passage acknowledges benefits but emphasizes risks with warning language ('warn,' 'post-antibiotic era'), creating a cautionary and concerned tone.
Question 95: Which hormone is secreted by the posterior pituitary gland to promote water reabsorption in the kidneys?
- Antidiuretic hormone (ADH) (Correct answer)
- Oxytocin
- Aldosterone
- Cortisol
Correct answer: Antidiuretic hormone (ADH)
ADH (also called vasopressin) is released from the posterior pituitary and acts on the collecting ducts of the kidney to increase water reabsorption, concentrating the urine and reducing fluid loss.
Question 96: My dearest friend was in a terrible automobile accident last Sunday night that left him hurt ____________.
- badly (Correct answer)
- baddest
- worst
- bad
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 97: Write 1,763 as a Roman numeral
- MDCCLXII
- \tMCDXXXVI
- MDCCLXIII (Correct answer)
- MDCCLII
Correct answer: MDCCLXIII
To write 1,763 as a Roman numeral, break down the number by place value. M represents 1000, DCC represents 700 (500 + 100 + 100), LX represents 60 (50 + 10), and III represents 3 (1 + 1 + 1). Combining these, 1,763 becomes MDCCLXIII.
Question 98: 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 equilibrium position would move, resulting in the formation of more reactants.
- Nothing, because the reaction has reached equilibrium.
- The reaction would heat up
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 99: Which statement best describes an exothermic chemical reaction?
- It only occurs at temperatures above 100 °C.
- It absorbs heat energy from the surroundings.
- It requires a catalyst to release energy.
- It releases heat energy to the surroundings. (Correct answer)
Correct answer: It releases heat energy to the surroundings.
In an exothermic reaction, the products have less energy than the reactants, so the excess energy is released as heat into the surroundings (e.g., combustion).
Question 100: An atom having an electrical charge is referred to as a(n):
- Solid
- Electron
- Molecule
- Ion (Correct answer)
Correct answer: Ion
An atom becomes an ion when it gains or loses one or more electrons, resulting in a net electrical charge. If an atom loses electrons, it becomes a positively charged cation; if it gains electrons, it becomes a negatively charged anion. Molecules are neutral combinations of atoms, and electrons are subatomic particles.
Question 101: How many gallons are in 576 ounces?
- 288 gallons
- 4.5 gallons (Correct answer)
- 4 gallons
- 5 gallons
Correct answer: 4.5 gallons
To convert ounces to gallons, 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). To find how many gallons are in 576 ounces, divide 576 by 128. This calculation results in 4.5 gallons.
Question 102: A nurse reads a study claiming a new wound care product heals burns 50% faster. The study was funded by the product manufacturer and had only 12 participants. What is the most appropriate response?
- Immediately adopt the new product for all burn patients
- Dismiss the study entirely because it was industry-funded
- Seek additional independent studies with larger sample sizes before changing practice (Correct answer)
- Recommend the product to patients who ask about it
Correct answer: Seek additional independent studies with larger sample sizes before changing practice
Critical thinking requires evaluating evidence quality. A small, industry-funded study needs corroboration from larger, independent research before changing clinical practice.
Question 103: What is the only artery in the body to carry oxygen-poor blood?
- Vena Cava
- Interosseous artery
- Pulmonary Artery (Correct answer)
- Renal Artery
Correct answer: Pulmonary Artery
The pulmonary artery is unique among arteries because it carries deoxygenated blood. It transports blood from the right ventricle of the heart to the lungs, where the blood will pick up oxygen and release carbon dioxide. All other arteries in the systemic circulation carry oxygenated blood away from the heart.
Question 104: After the storm, telephone poles ____________ all over the street.
- were lying (Correct answer)
- laid
- were laying
- lied
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 105: What is the molarity of an aqueous solution containing 0.40 moles of sugar in 5 liters of water?
- 400.0 M
- 8.0 M
- 0.08 M (Correct answer)
- 0.04 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 106: Which of the following statements about most metals is false?
- They are ductile
- They make up the majority of elements on the periodic table
- They are gases at room temperature (Correct answer)
- None of the above
Correct answer: They are gases at room temperature
Most metals are known for properties like ductility, malleability, and being good conductors of heat and electricity. They constitute the majority of elements on the periodic table and are typically solid at room temperature, with mercury being a notable exception. Therefore, the statement that they are gases at room temperature is false.
Question 107: 45.\t5 1\/2 divide by 2 1\/2
- 21
- 2 3\/4
- 2.0
- 2 1\/5 (Correct answer)
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 108: Which of the following is the best definition of the word languid?
- Talkative
- Depressed
- Warm
- Sluggish (Correct answer)
Correct answer: Sluggish
The word 'languid' describes a person or manner that is slow and relaxed, or lacking in vigor or energy. It suggests a state of weariness, listlessness, or a general lack of enthusiasm. Therefore, 'sluggish' is the best definition, as it implies a lack of energy and slow movement.
Question 109: A cell with 46 chromosomes undergoes meiosis. How many chromosomes does each resulting gamete contain?
- 12
- 23 (Correct answer)
- 92
- 46
Correct answer: 23
Meiosis halves the chromosome number, producing haploid gametes with 23 chromosomes.
Question 110: What is the atomic number of an unknown element with 45 protons and an atomic mass of 64?
- 64
- Cannot be determined
- 45 (Correct answer)
- 22
Correct answer: 45
The atomic number of an element is defined by the number of protons in the nucleus of an atom. Since the unknown element has 45 protons, its atomic number is 45. The atomic mass, which is the sum of protons and neutrons, does not change the atomic number itself.
Question 111: \tHow many milliliters are contained in 3 table spoons of fluid? (Enter numerical value only).
- 45 milliliters (Correct answer)
- 4.5 milliliters
- 450 milliliters
- 405 milliliters
Correct answer: 45 milliliters
To convert tablespoons to milliliters, you use the standard conversion factor where 1 tablespoon (tbsp) is equal to 15 milliliters (ml). Therefore, to find the milliliters in 3 tablespoons, you multiply 3 by 15. This calculation yields 45 milliliters.
Question 112: What is the best definition of the word dichotomy?
- Division (Correct answer)
- Trepidation
- Achievement
- Truncation
Correct answer: Division
Dichotomy refers to a division or contrast between two things that are or are represented as being opposed or entirely different. It highlights a sharp separation or contrast between two distinct parts, ideas, or categories. For example, the dichotomy between good and evil.
Question 113: The term 'benign' in medical terminology means:
- Of unknown origin
- Not harmful or not cancerous (Correct answer)

Correct answer: Not harmful or not cancerous
'Benign' means not harmful, not cancerous, or not threatening to health, as opposed to 'malignant' which indicates cancerous or harmful.
Question 114: In Celsius, what are 98.6 degrees Fahrenheit?
- 37 degrees Celsius (Correct answer)
- 70.50 degrees Celsius
- 119 degrees Celsius
- 86.70 degrees Celsius
Correct answer: 37 degrees Celsius
To convert degrees Fahrenheit to Celsius, use the formula C = (F - 32) * 5/9. Substituting 98.6 degrees Fahrenheit, the calculation is (98.6 - 32) * 5/9 = 66.6 * 5/9 = 37 degrees Celsius. This is the standard normal human body temperature.
Question 115: What is the body's biggest organ?
- skin (Correct answer)
- brain
- stomach
- lungs
Correct answer: skin
The skin is the largest organ of the human body, both in terms of surface area and weight. It forms a protective barrier against the environment, regulates body temperature, and performs various sensory and metabolic functions. While the lungs, stomach, and brain are vital organs, they are not as large as the skin.
Question 116: A reading passage describes steps in order: first, second, then finally. What text structure is being used?
- Cause and effect
- Problem and solution
- Sequence/chronological order (Correct answer)
- Compare and contrast
Correct answer: Sequence/chronological order
Signal words like 'first,' 'then,' and 'finally' indicate sequence or chronological order.
Question 117: What is the meaning of incision?
- Injection
- Fracture
- Cut (Correct answer)
- Closure
Correct answer: Cut
An 'incision' is a surgical cut made in skin or flesh, typically during an operation or medical procedure. It is a precise opening created by a surgeon's instrument. Therefore, 'cut' is the most direct and accurate definition of an incision.
Question 118: What is the hormone that assists estrogen in stimulating the formation of the endometrium?
- testosterone
- progesterone (Correct answer)
- luteinizing hormone
- oxytocin
Correct answer: progesterone
Progesterone is a key steroid hormone primarily produced by the corpus luteum after ovulation. It works in conjunction with estrogen to prepare the uterine lining (endometrium) for potential implantation of a fertilized egg. Progesterone stimulates the thickening and vascularization of the endometrium, making it receptive for pregnancy.
Question 119: When a care plan states a patient is 'ambulatory,' it means the patient is:
- Receiving intravenous fluids
- Scheduled for surgery
- Able to walk (Correct answer)
- Confined to bed rest
Correct answer: Able to walk
'Ambulatory' derives from the Latin 'ambulare,' meaning to walk. An ambulatory patient is capable of walking and does not require a stretcher or bed transport.
Question 120: To 'palpate' an area means to:
- Listen with a stethoscope
- Tap it sharply
- Look closely at it
- Examine by touch (Correct answer)
Correct answer: Examine by touch
Palpate means to examine by feeling with the hands or fingers.
Question 121: 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).
- 38 hours
- 3.8 hours
- 37 hours (Correct answer)
- 36.73 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 122: A nurse validates a patient's reported symptom against objective findings to:
- Ensure accuracy of the data (Correct answer)
- Skip assessment
- Save time
- Avoid the patient
Correct answer: Ensure accuracy of the data

Question 123: 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 124: What is the term for the diffusion of water across a selectively permeable membrane?
- Endocytosis
- Osmosis (Correct answer)
- Phagocytosis
- Active transport
Correct answer: Osmosis

Question 126: Where is the pyloric sphincter located?
- Between the small and large intestine
- Between the esophagus and stomach
- Between the stomach and small intestine (Correct answer)
- Between the rectum and anus
Correct answer: Between the stomach and small intestine
The pyloric sphincter is a ring of smooth muscle located at the distal end of the stomach, specifically at the junction where the stomach connects to the first part of the small intestine, called the duodenum. Its primary function is to regulate the flow of partially digested food (chyme) from the stomach into the small intestine, preventing rapid emptying and allowing for proper digestion.
Question 127: In an exothermic reaction, what happens to energy?
- Energy remains unchanged
- Energy is absorbed from the surroundings
- Energy is released to the surroundings (Correct answer)
- Energy is converted entirely to matter
Correct answer: Energy is released to the surroundings
Exothermic reactions release energy (usually as heat) to the surroundings, resulting in a negative enthalpy change (ÎH < 0).
Question 128: Two-thirds of an ounce of liquid is contained in a sample. What is the volume in milliliters (mL)?
- 25 mL
- 35 mL
- 5 mL
- 20 mL (Correct answer)
Correct answer: 20 mL
To convert ounces to milliliters, use the conversion factor that 1 ounce is approximately equal to 29.5735 mL. Therefore, two-thirds of an ounce is (2/3) * 29.5735 mL, which calculates to approximately 19.715 mL. Rounding this to the nearest whole number, or using a common approximation of 1 oz â 30 mL, gives 20 mL.
Question 129: Which of the following is the best definition of the word taciturn?
- Attentive
- Alert
- Uncooperative
- Reserved (Correct answer)
Correct answer: Reserved
The word 'taciturn' describes a person who is reserved or uncommunicative in speech, saying little. Such individuals tend to be quiet and prefer not to talk much in social situations. Therefore, 'reserved' accurately captures this characteristic of being withdrawn and not openly expressive.
Question 130: What is the closest definition of the word proximal?
- far
- away
- center (Correct answer)
- up
Correct answer: center
In anatomy, 'proximal' refers to a position closer to the center of the body or the point of attachment of a limb. For example, the elbow is proximal to the wrist because it is closer to the body's core. Among the given choices, 'center' best captures the idea of being closer to the main part or origin.
Question 131: calculated by taking the object's initial and final speeds and averaging them
- Force
- Average velocity (Correct answer)
- acceleration
- average speed
Correct answer: Average velocity
Average velocity is calculated by taking the displacement (change in position) over time. While the question's phrasing mentions 'initial and final speeds and averaging them,' which is a simplified way to think about average velocity in certain contexts (like constant acceleration), it most closely aligns with the concept of average velocity, which considers the overall change in position over time, encompassing both speed and direction. Average speed, in contrast, is typically total distance divided by total time.
Question 132: What is the role of the cell membrane's phospholipid bilayer?
- Regulating what enters and exits the cell (Correct answer)
- Storing genetic information
- Producing proteins
- Generating ATP
Correct answer: Regulating what enters and exits the cell
The selectively permeable bilayer controls movement of substances in and out.
Question 133: Which word is spelled correctly?
- accomodate
- accommodate (Correct answer)
- acommodate
- acomodate
Correct answer: accommodate
'Accommodate' is the correct spelling, containing double 'c' and double 'm.' It is one of the most commonly misspelled words in English. A memory trick: the word is large enough to accommodate two c's and two m's.
Question 134: All of the following factors influence the pace of a chemical reaction except?
- Presence of catalysts
- Temperature
- Amount of mass lost (Correct answer)
- 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 135: If a wound is 'suppurating,' it is:
- Drying out
- Healing cleanly
- Bleeding heavily
- Discharging pus (Correct answer)
Correct answer: Discharging pus
Suppurating means forming or discharging pus.
