Rationales
Question 1: Which of the following best describes the primary
purpose of an expository text?
A. To persuade the reader to adopt a particular viewpoint
B. To entertain the reader with a compelling narrative
C. To inform the reader by explaining a concept or process
D. To express the author's personal emotions and experiences
CORRECT ANSWER: C. To inform the reader by explaining a
concept or process
Rationale: Expository writing is defined by its intent to explain, describe, or
inform. Unlike persuasive text, which seeks to convince, or narrative text,
which seeks to entertain, expository text presents factual information in a
structured manner. Options A, B, and D describe other rhetorical modes.
Question 2: A nurse is calculating a patient's fluid intake. The
patient consumed 8 ounces of water, 4 ounces of juice, and 6
ounces of broth. What is the total intake in milliliters? (1 oz ≈ 30
mL)
A. 420 mL
B. 480 mL
C. 540 mL
D. 600 mL
CORRECT ANSWER: C. 540 mL
Rationale: Total ounces = 8 + 4 + 6 = 18 oz. 18 oz × 30 mL/oz = 540 mL.
Options A, B, and D result from incorrect multiplication or addition errors.
Question 3: Which of the following organelles is primarily
responsible for ATP synthesis in eukaryotic cells?
A. Ribosome
B. Mitochondrion
,C. Golgi apparatus
D. Lysosome
CORRECT ANSWER: B. Mitochondrion
Rationale: Mitochondria are the site of oxidative phosphorylation and ATP
production. Ribosomes synthesize proteins, the Golgi apparatus modifies
and packages proteins, and lysosomes contain digestive enzymes.
Question 4: Which sentence demonstrates correct subject-verb
agreement?
A. The list of items on the desk are long.
B. Each of the students have completed the assignment.
C. Neither the nurse nor the doctor were available.
D. The bouquet of flowers sits on the table.
CORRECT ANSWER: D. The bouquet of flowers sits on the table.
Rationale: The subject "bouquet" is singular, requiring the singular verb
"sits." In A, the subject is "list" (singular), not "items." In B, "each" is singular.
In C, with "neither...nor," the verb agrees with the nearer subject ("doctor"),
requiring "was."
Question 5: A patient's temperature is recorded as 39.2°C. What is
this temperature in Fahrenheit using the formula F = (C × 9/5) +
32?
A. 98.6°F
B. 100.4°F
C. 102.6°F
D. 104.0°F
CORRECT ANSWER: C. 102.6°F
Rationale: F = (39.2 × 1.8) + 32 = 70.56 + 32 = 102.56, which rounds to
102.6°F. Option A is normal body temperature. Option B corresponds to
38°C. Option D corresponds to 40°C.
Question 6: Which of the following is a primary source for a
research paper on the effectiveness of hand hygiene in clinical
settings?
A. A textbook chapter summarizing infection control guidelines
B. A systematic review published in a nursing journal
,C. A randomized controlled trial published in a peer-reviewed journal
D. A hospital policy manual citing multiple studies
CORRECT ANSWER: C. A randomized controlled trial published in
a peer-reviewed journal
Rationale: A primary source presents original research data. A randomized
controlled trial generates original findings. Textbooks, systematic reviews,
and policy manuals are secondary sources that synthesize or interpret
primary research.
Question 7: Simplify the expression: (3x + 2)(x − 5)
A. 3x² − 13x − 10
B. 3x² + 13x − 10
C. 3x² − 13x + 10
D. 3x² − 17x − 10
CORRECT ANSWER: A. 3x² − 13x − 10
Rationale: Using FOIL: (3x)(x) + (3x)(−5) + (2)(x) + (2)(−5) = 3x² − 15x +
2x − 10 = 3x² − 13x − 10. Options B, C, and D result from sign or
multiplication errors.
Question 8: Which of the following statements about enzymes is
correct?
A. Enzymes are consumed in the reactions they catalyze.
B. Enzymes lower the activation energy of a reaction.
C. Enzymes are permanently altered by the reactions they catalyze.
D. Enzymes function optimally at any pH.
CORRECT ANSWER: B. Enzymes lower the activation energy of a
reaction.
Rationale: Enzymes are biological catalysts that reduce activation energy,
enabling reactions to proceed more readily. They are not consumed or
permanently altered. Enzyme activity is pH-dependent, with most enzymes
having an optimal pH range.
Question 9: Which of the following sentences contains a misplaced
modifier?
A. Walking to the clinic, the nurse noticed a stray dog.
B. The nurse noticed a stray dog while walking to the clinic.
, C. While walking to the clinic, the nurse noticed a stray dog.
D. The stray dog, walking to the clinic, was noticed by the nurse.
CORRECT ANSWER: D. The stray dog, walking to the clinic, was
noticed by the nurse.
Rationale: In D, the phrase "walking to the clinic" appears to modify "the
stray dog," implying the dog was walking to the clinic, which is likely not the
intended meaning. The modifier should apply to the nurse. A, B, and C
correctly place the modifier near the intended subject.
Question 10: What is the mean of the following data set: 12, 15, 18,
22, 25?
A. 16.4
B. 17.8
C. 18.4
D. 19.2
CORRECT ANSWER: C. 18.4
Rationale: Mean = (12 + 15 + 18 + 22 + 25) / 5 = = 18.4. Options A,
B, and D reflect calculation errors.
Question 11: Which of the following describes the function of the
sinoatrial (SA) node?
A. It relays electrical impulses from the brain to the heart.
B. It acts as the natural pacemaker, initiating electrical impulses.
C. It controls the contraction of the ventricles directly.
D. It regulates blood pressure through baroreceptor feedback.
CORRECT ANSWER: B. It acts as the natural pacemaker, initiating
electrical impulses.
Rationale: The SA node generates spontaneous electrical impulses that set
the heart's rhythm. It is located in the right atrium. The atrioventricular (AV)
node relays impulses to the ventricles. The SA node does not directly
regulate blood pressure; that involves baroreceptors and the medulla.
Question 12: Which of the following is the correct order of
operations for solving the expression 4 + 3 × (8 − 5)² ÷ 3?
A. Add, multiply, subtract, divide, square
B. Subtract, square, multiply, divide, add
