CHAPTER 1: THE FOUNDATIONS OF BIOCHEMISTRY
This chapter introduces the chemical principles underlying
biochemistry, including atomic structure, chemical bonds,
thermodynamics, pH, and buffer systems. It emphasizes the molecular
basis of life, macromolecule interactions, and energy transformations.
Nurses must understand these fundamentals to appreciate drug
actions, metabolic pathways, and laboratory interpretations in clinical
practice.
1. Which element is most abundant in living organisms?
A. Nitrogen
B. Carbon
C. Oxygen
D. Phosphorus
- CORRECT ANSWER - : C
Rationale: Oxygen is the most abundant element in the human
body by mass, forming water and organic molecules; other
elements are essential but less abundant.
, 2. What type of bond involves the sharing of electron pairs between
atoms?
A. Ionic
B. Hydrogen
C. Covalent
D. Van der Waals
- CORRECT ANSWER - : C
Rationale: Covalent bonds share electrons between atoms,
creating stable molecules.
Ionic and hydrogen bonds involve attraction, not electron
sharing.
3. Which property of water allows it to dissolve many ionic
compounds?
A. High heat capacity
B. Polar nature
C. Nonpolar nature
D. Low density as ice
- CORRECT ANSWER - : B
Rationale: Water’s polarity enables it to interact with and
dissolve ions, unlike nonpolar substances. High heat capacity
and density are separate physical properties.
4. What is the pH of a neutral solution at 25°C?
A. 0
B. 7
C. 14
D. 1
