1. Which organelle is responsible for producing the bulk of adenosine
triphosphate (ATP) in eukaryotic cells?
A) Golgi apparatus
B) Mitochondrion
C) Smooth endoplasmic reticulum
D) Peroxisome
Mitochondria are the primary sites of aerobic respiration and ATP synthesis,
containing the enzymes for the electron transport chain and oxidative
phosphorylation.
2. Read the following passage: “The nurse assessed the patient’s vital signs,
noting an elevated heart rate and slightly decreased oxygen saturation.
Although the patient reported feeling fatigued, there was no evidence of
cyanosis.” Which of the following is an inference a reader can make?
A) The patient is experiencing a myocardial infarction.
B) The patient may be compensating for reduced oxygenation by increasing
heart rate.
C) Cyanosis is always present with decreased oxygen saturation.
D) The nurse ignored the patient’s fatigue.
The text indicates elevated heart rate and decreased O₂ saturation without
cyanosis. This suggests a compensatory increase in heart rate to maintain oxygen
delivery, an inference consistent with physiological responses.
, 3. Simplify the expression: 4(2x – 3) + 5x
A) 13x – 12
B) 8x – 3 + 5x
C) 13x – 12
D) 13x + 12
4(2x – 3) = 8x – 12; plus 5x yields 13x – 12. So the simplified expression is 13x – 12.
4. Which of the following structures prevents food from entering the trachea
during swallowing?
A) Uvula
B) Epiglottis
C) Pharynx
D) Glottis
The epiglottis is a cartilaginous flap that covers the trachea during swallowing,
directing food to the esophagus and preventing aspiration.
5. Which sentence is grammatically correct?
A) The committee were divided in its opinion.
B) The committee was divided in its opinion.
C) The committee were divided in their opinion.
D) The committee were divided in its opinion.
In American English, collective nouns like “committee” take singular verbs and
pronouns when the group acts as a unit. “Committee was... its” is correct.
6. A solution has a pH of 9. How does its hydrogen ion concentration compare
to a neutral solution?
A) [H⁺] is 100 times higher.
B) [H⁺] is 10 times higher.
C) ** [H⁺] is 100 times lower.**
D) [H⁺] is 1,000 times lower.
pH 7 is neutral. pH 9 is two pH units above 7; each unit is a 10-fold change.
Therefore [H⁺] is 10⁻² (100 times) lower than at pH 7.
, 7. A recipe requires 2/3 cup of sugar for one batch. How many cups of sugar
are needed for 2 1/4 batches?
A) 1 1/3 cups
B) 1 1/2 cups
C) 1 1/2 cups
D) 1 2/3 cups
2/3 × 2¼ = (2/3) × (9/4) = 18/12 = 1 6/12 = 1½ cups. So 1½ cups.
8. Which of the following hormones lowers blood calcium levels by promoting
calcium deposition in bone?
A) Parathyroid hormone
B) Calcitonin
C) Calcitriol
D) Thyroxine
Calcitonin, produced by thyroid C-cells, inhibits osteoclast activity and stimulates
calcium uptake by bones, lowering blood Ca²⁺.
9. In a study, researchers found a correlation coefficient of –0.85 between
hours of exercise per week and resting heart rate. What does this indicate?
A) No relationship exists.
B) As exercise increases, resting heart rate increases.
C) As exercise increases, resting heart rate tends to decrease strongly.
D) Resting heart rate causes less exercise.
A negative r near –1 indicates a strong inverse linear relationship: more exercise is
associated with a lower resting heart rate.
10.Identify the predicate in the sentence: “The experienced nurse carefully
administered the medication.”
A) The experienced nurse
B) carefully
C) administered the medication
D) the medication
