,1. A researcher is studying the effect of a new drug on blood pressure. The study
design includes a control group receiving a placebo and an experimental group
receiving the drug. After 8 weeks, the mean systolic blood pressure reduction in the
control group is 2 mmHg (SD = 3 mmHg) and in the experimental group is 8 mmHg
(SD = 4 mmHg). The p-value from an independent t-test is 0.01. Which of the
following is the most appropriate interpretation?
Answer: The null hypothesis that the drug and placebo have equal effects can be
rejected, but clinical significance may depend on other factors.
Option D correctly distinguishes statistical significance from clinical significance. A
p-value of 0.01 indicates that if the null hypothesis were true (no difference), the
probability of observing a difference as extreme as 6 mmHg is 1%. This allows
rejecting the null. However, statistical significance does not guarantee clinical
importance; the magnitude of effect, variability, and patient impact must be considered.
Options A and B conflate statistical with clinical significance; A is partially correct but
omits nuance. Option C misinterprets the p-value (it is not the probability that the
result is due to chance).
2. A patient with type 2 diabetes mellitus is prescribed metformin. Which of the
following best describes the primary mechanism of action of this medication?
Answer: Increases peripheral glucose uptake and decreases hepatic
gluconeogenesis.
Metformin is a biguanide that primarily works by decreasing hepatic glucose
production (gluconeogenesis) and improving insulin sensitivity, increasing peripheral
glucose uptake. Option A describes sulfonylureas. Option C describes alpha-glucosidase
inhibitors. Option D describes thiazolidinediones.
3. Which of the following sentences contains a correctly placed modifier?
Answer: The doctor prescribed the medication after reviewing the lab results
carefully.
Option B has no dangling or misplaced modifier; 'carefully' modifies 'reviewing'
logically. Option A has a dangling modifier ('Walking through the park' incorrectly
modifies 'the flowers'). Option C has a dangling modifier (the nurse was not diagnosed
with hypertension). Option D is grammatically correct but the relative clause is
correctly placed; however, the question asks for a correctly placed modifier, and B is the
best example. Actually D is also correct but B is clearer. Nonetheless, B is the intended
answer.

,4. A solution contains 0.9% NaCl (mass/volume). How many grams of NaCl are
needed to prepare 500 mL of this solution?
Answer: 4.5 g
0.9% w/v means 0.9 g per 100 mL. For 500 mL: (0.9 g/100 mL) * 500 mL = 4.5 g.
Option B (0.45 g) would be for 50 mL; C (45 g) would be for 5000 mL; D (0.045 g) is for
5 mL.
5. Which of the following best describes the relationship between the hypothalamus
and the pituitary gland?
Answer: The hypothalamus produces antidiuretic hormone and oxytocin, which
are stored and released from the posterior pituitary.
The hypothalamus produces ADH and oxytocin, which are transported to the posterior
pituitary for storage and release. Option A is incorrect because the hypothalamus does
not release anterior pituitary hormones; it releases regulatory hormones. Option B is
incorrect because the posterior pituitary is controlled by neural signals, not releasing
hormones. Option D is incorrect because while dopamine is a prolactin-inhibiting
factor, there are other inhibitory hormones (e.g., somatostatin inhibits growth
hormone).
6. Which of the following sentences is grammatically correct?
Answer: The data collected from the study indicates a significant trend.
In option C, 'data' is treated as a singular mass noun (common in academic writing), so
the verb 'indicates' is correct. Option A has subject-verb agreement error: the subject is
'nurse' (singular), so the verb should be 'is attending'. Option B: with 'either...or', the
verb agrees with the nearer subject; 'family members' is plural, so 'have' is correct.
Option D: 'each' is singular, so 'was given' is correct.

, 7. A researcher conducts a study to examine the relationship between hours of sleep
and academic performance. The Pearson correlation coefficient is calculated as r =
-0.85, with a p-value < 0.001. Which of the following is the most appropriate
conclusion?
Answer: There is a strong negative correlation, and the result is statistically
significant, but causation cannot be inferred from this study.
r = -0.85 indicates a strong negative correlation (magnitude > 0.7). The p-value
indicates significance. However, correlation does not imply causation; other variables
may confound the relationship. Option A misinterprets the sign. Option B incorrectly
claims causation. Option D is wrong because the magnitude (0.85) indicates strong
correlation regardless of sign.
8. Which of the following best describes the function of the ribosome in protein
synthesis?
Answer: It catalyzes the formation of peptide bonds between amino acids during
translation.
Ribosomes facilitate peptide bond formation (peptidyl transferase activity) during
translation. Option B describes RNA polymerase. Option C describes tRNA. Option D
describes the Golgi apparatus.
9. A patient's blood test shows: pH 7.25, PaCO2 50 mmHg, HCO3- 24 mEq/L.
Which of the following acid-base disorders is present?
Answer: Respiratory acidosis without renal compensation.
Low pH (7.25) indicates acidosis. Elevated PaCO2 (50 mmHg) indicates respiratory
acidosis. HCO3- is normal (24 mEq/L), indicating no renal compensation
(compensation takes hours to days). Therefore, it is acute respiratory acidosis. Option
A: metabolic acidosis would show low HCO3-; C: pH would be high; D: pH high,
HCO3- high.
10. Which of the following is the correct order of steps in the scientific method?
Answer: Observation, hypothesis, experiment, data analysis, conclusion.
The scientific method typically begins with observation, then forming a hypothesis,
conducting an experiment to test it, analyzing the data, and drawing a conclusion.
Option A places hypothesis before observation. Option C starts with experiment.
Option D starts with theory.
