1. Where would a nonpregnant patient with normal anatomy most commonly have pain in acute appendicitis?
- A. Right upper quadrant.
- B. Left upper quadrant.
- C. Right lower quadrant.
- D. Left lower quadrant.
Correct answer: C
Rationale: In acute appendicitis, nonpregnant patients with normal anatomy commonly experience pain in the right lower quadrant of the abdomen. The pain usually starts around the umbilicus or epigastric area and then migrates to the right lower quadrant as inflammation progresses in the appendix. This classic migration of pain is known as McBurney's point tenderness and is a key clinical feature in diagnosing appendicitis.
2. What type of reaction is represented by the following equation: 2C₆H₁₄ + 19O₂ → 12CO + 14H₂O?
- A. Substitution reaction
- B. Acid-base reaction
- C. Enzyme reaction
- D. Combustion reaction
Correct answer: D
Rationale: The given chemical equation represents a combustion reaction. Combustion reactions involve the burning of a hydrocarbon (C₆H₁₄) in the presence of oxygen (O₂) to produce carbon monoxide (CO) and water (H₂O). Combustion reactions typically release heat and light energy. In this case, the reactants are a hydrocarbon and oxygen, resulting in the formation of carbon monoxide and water. Choices A, B, and C are incorrect because the reaction does not involve substitution, acid-base reactions, or enzyme catalysis. Combustion reactions are characterized by the rapid combination of a substance with oxygen, leading to the production of heat and light energy.
3. Which option best exemplifies an author's use of alliteration and personification?
- A. Her mood hung about her like a weary cape, very dull from wear.
- B. It shuddered, swayed, shook, and screamed its way into dust under hot flames.
- C. The house was a starch sentry, warning visitors away.
- D. At its shoreline, visitors swore they heard the siren call of the cliffs above.
Correct answer: B
Rationale: Choice B best exemplifies an author's use of alliteration and personification. The sentence 'It shuddered, swayed, shook, and screamed its way into dust under hot flames' personifies an inanimate object (it) by attributing human actions to it, combining alliteration with the repeated 's' sounds. Choices A, C, and D do not contain both alliteration and personification. Choice A mainly focuses on simile and lacks alliteration. Choice C features personification but lacks alliteration. Choice D includes personification but lacks alliteration as well.
4. Dr. Lee observed that 30% of all his patients developed an infection after taking a certain antibiotic. He further noticed that 5% of that 30% required hospitalization to recover from the infection. What percentage of Dr. Lee's patients were hospitalized after taking the antibiotic?
- A. 1.50%
- B. 5%
- C. 15%
- D. 30%
Correct answer: A
Rationale: To find the percentage of Dr. Lee's patients hospitalized after taking the antibiotic, we need to calculate 30% of 5%. First, convert 30% and 5% to decimals: 30% = 0.30 and 5% = 0.05. Multiply 0.30 by 0.05 to get 0.015. To convert 0.015 to a percentage, multiply by 100, resulting in 1.5%. Therefore, only 1.50% of Dr. Lee's patients were hospitalized after taking the antibiotic. Choice A is correct. Choice B (5%) is incorrect as it represents the percentage of patients who developed an infection and not those hospitalized. Choices C (15%) and D (30%) are also incorrect percentages as they do not accurately reflect the proportion of hospitalized patients in this scenario.
5. The Becquerel (Bq) is the designated unit for quantifying:
- A. Electron volt (eV) measurements of energy
- B. Radioactivity
- C. Electric charge (Coulombs)
- D. Force (Newtons)
Correct answer: B
Rationale: The Becquerel (Bq) is the unit used to measure radioactivity, specifically the activity of a quantity of radioactive material. It represents the number of radioactive disintegrations or transformations per unit of time. Choice A, electron volt (eV), is a unit of energy, not radioactivity. Choice C, electric charge (Coulombs), is measured in Coulombs, not Becquerels. Choice D, force (Newtons), is a unit of force, not radioactivity. Therefore, the correct answer is B.
