1. Where would a nonpregnant patient with normal anatomy most commonly have pain in acute appendicitis?

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 is the term for a microorganism that lives on or in the human body and normally causes no disease or harm?

Correct answer: B

Rationale: The correct term for a microorganism that lives on or in the human body without causing harm is a commensal microorganism. Commensal microorganisms coexist with the host without causing disease or harm. Choice A, 'Bacteria,' is too broad as not all bacteria are harmless in the body. Choice C, 'Microorganism,' is a general term and does not specifically refer to the harmless nature of the organism. Choice D, 'Host,' refers to the organism harboring the microorganism, not the microorganism itself.

3. An atom has 5 protons, 5 neutrons, and 6 electrons. What is the electric charge of this atom?

Correct answer: C

Rationale: The correct answer is 'Negative.' An atom becomes negatively charged when it has more electrons than protons. In this case, the atom has 6 electrons and 5 protons, resulting in a net negative charge. Choice A 'Neutral' is incorrect because the atom is not balanced in terms of protons and electrons. Choice B 'Positive' is incorrect because having more electrons than protons results in a negative charge. Choice D 'Undetermined' is incorrect, as the charge can be determined based on the relative number of protons and electrons.

4. How many kilograms are in 1,800 grams?

Correct answer: B

Rationale: To convert grams to kilograms, divide by 1,000 since there are 1,000 grams in a kilogram. Therefore, 1,800 grams is equal to 1.8 kilograms (1,800 / 1,000 = 1.8). Choice A (0.18) is incorrect because it incorrectly shifted the decimal point. Choice C (18) is incorrect as it represents the direct conversion without dividing by 1,000. Choice D (180) is incorrect as it is in the hundreds and not the correct conversion to kilograms. The correct answer is B.

5. What is the term for the number of moles of solute per liter of solution?

Correct answer: A

Rationale: Molarity is the correct term for the number of moles of solute per liter of solution. It is expressed as moles of solute divided by liters of solution. Molality (B) is similar but is moles of solute per kilogram of solvent. Normality (C) is the number of equivalents of solute per liter of solution, and Concentration (D) is a general term for the amount of solute present in a given quantity of solution. Therefore, the correct answer is A, molarity, as it specifically refers to moles of solute per liter of solution.
