Question 1: Which of the following correctly orders the layers of the epidermis from most
superficial to deepest?
• A. Stratum spinosum, Stratum basale, Stratum corneum, Stratum granulosum, Stratum
lucidum
• B. Stratum corneum, Stratum lucidum, Stratum granulosum, Stratum spinosum, Stratum
basale
• C. Stratum corneum, Stratum spinosum, Stratum basale, Stratum granulosum, Stratum
lucidum
• D. Stratum basale, Stratum spinosum, Stratum granulosum, Stratum lucidum, Stratum
corneum
Answer: B. Stratum corneum, Stratum lucidum, Stratum granulosum, Stratum spinosum,
Stratum basale
Rationale: The layers of the epidermis, from the most superficial (outermost) to the deepest
(innermost), are: Corneum, Lucidum, Granulosum, Spinosum, Basale. A helpful mnemonic is
"Come Let's Get Sun Burned." The stratum basale is the deepest layer where new skin cells are
generated .

Question 2: A student is writing a research paper on the effects of sleep deprivation on
cognitive function. Which of the following sources would be the most credible and relevant for
this topic?
• A. A blog post by a college student describing their personal experience with all-nighters.
, • B. A peer-reviewed study published in a journal on sleep medicine.
• C. A Wikipedia article summarizing the topic.
• D. An opinion editorial in a popular magazine.
Answer: B. A peer-reviewed study published in a journal on sleep medicine.
Rationale: Peer-reviewed studies published in academic journals are considered the gold
standard for credible, evidence-based information in research. They have undergone rigorous
scrutiny by experts in the field. Sources like personal blogs, opinion pieces, and user-edited
encyclopedias lack this level of authority and verification .
Mathematics
Question 3: A nurse needs to administer a medication. The dosage is 2.5 mg per kilogram of
body weight. The patient weighs 154 pounds. How many milligrams of the medication should
the nurse administer? (1 kg ≈ 2.2 lbs)
• A. 67.0 mg
• B. 175.0 mg
• C. 61.6 mg
• D. 38.5 mg
Answer: B. 175.0 mg
Rationale:
1. Convert pounds to kilograms: 154 lbs ÷ 2.2 lbs/kg = 70 kg
2. Calculate the dosage: 2.5 mg/kg × 70 kg = 175 mg
English & Language Usage
Question 4: Which of the following sentences is grammatically correct?
• A. The group of students are going on a field trip.
, • B. Neither the teacher nor the students is in the classroom.
• C. Each of the candidates have submitted their application.
• D. The committee has reached its final decision.
Answer: D. The committee has reached its final decision.
Rationale: Collective nouns like "committee," "team," and "group" are typically treated as
singular subjects in American English and take singular verbs and pronouns. The phrase "has
reached" is singular, and "its" correctly agrees. The other options contain errors in subject-verb
agreement .

Question 5: Which of the following correctly describes the function of the ribosome?
• A. To package and sort proteins for secretion from the cell.
• B. To synthesize proteins by translating messenger RNA (mRNA).
• C. To generate adenosine triphosphate (ATP) through cellular respiration.
• D. To store genetic material and control cellular activities.
Answer: B. To synthesize proteins by translating messenger RNA (mRNA).
Rationale: Ribosomes are the cellular machinery responsible for protein synthesis. They read
the genetic code carried by mRNA and link amino acids together in the correct order. The Golgi
apparatus packages proteins (A), mitochondria generate ATP (C), and the nucleus stores
genetic material (D).
Question 6: A solution has a pH of 3. Which of the following statements is true regarding this
solution?
• A. It has a high concentration of hydroxide ions (OH⁻) and is basic.
• B. It has a low concentration of hydrogen ions (H⁺) and is neutral.
• C. It has a high concentration of hydrogen ions (H⁺) and is acidic.
