1. What is the primary purpose of studying chemistry in a nursing education program
and healthcare environment?
,A. To understand substances, reactions, medications, and biological processes
B. To memorize only chemical element symbols
C. To avoid learning about body chemistry
D. To replace all medical science courses
Answer: A — To understand substances, reactions, medications, and biological
processes
Explanation:
Chemistry helps nurses understand medications, electrolytes, metabolism, acid-base
balance, and how substances interact in the human body.
2. Which statement best describes the difference between chemistry and other
scientific disciplines?
A. Chemistry studies matter, its properties, and how substances change
B. Chemistry only studies living organisms
C. Chemistry only studies mathematical calculations
D. Chemistry focuses only on laboratory equipment
Answer: A
Explanation:
Chemistry examines matter, composition, structure, properties, and chemical changes.
3. What is considered matter according to the basic principles of chemistry and
physical science?
,A. Anything that has mass and occupies space
B. Anything that can be seen by the human eye
C. Only substances found inside living organisms
D. Only liquids and solid materials
Answer: A
Explanation:
Matter has measurable mass and takes up physical space.
4. Which classification describes a substance that contains only one type of atom or
molecule?
A. Pure substance
B. Mixture
C. Solution
D. Suspension
Answer: A
Explanation:
A pure substance contains only one type of particle, such as an element or compound.
5. What is the main difference between an element and a compound in chemistry?
A. Elements contain one type of atom, while compounds contain chemically bonded atoms
of different elements
B. Elements always contain liquids, while compounds contain solids
, C. Compounds cannot be separated chemically
D. Elements contain multiple different substances
Answer: A
Explanation:
Elements consist of one kind of atom, while compounds contain two or more elements
chemically combined.
6. Which measurement unit is commonly used by scientists to measure mass in
laboratory settings?
A. Gram
B. Liter
C. Meter
D. Celsius
Answer: A
Explanation:
Mass is commonly measured in grams or kilograms.
7. What is the purpose of using significant figures when recording scientific
measurements?
A. To show the precision and reliability of measured values
B. To increase the numerical value of measurements
C. To remove all uncertainty from experiments
D. To avoid using laboratory equipment
