1. The most common cause of hospital-acquired infections (HAIs) are:
- A. Viruses
- B. Bacteria
- C. Fungi
- D. Parasites
Correct answer: B
Rationale: Rationale: Hospital-acquired infections (HAIs), also known as nosocomial infections, are infections that patients acquire during the course of receiving treatment in a healthcare facility. Among the options provided, bacteria are the most common cause of HAIs. Bacteria such as Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa are known to cause a wide range of infections in healthcare settings. While viruses, fungi, and parasites can also cause HAIs, bacteria are the most prevalent and significant pathogens responsible for these infections. Proper infection control measures, including hand hygiene, environmental cleaning, and antimicrobial stewardship, are essential in preventing and controlling HAIs caused by bacteria.
2. What literary device is used in the line "The sea whispered secrets to the shore"?
- A. Alliteration
- B. Personification
- C. Onomatopoeia
- D. Hyperbole
Correct answer: B
Rationale: The sentence gives human qualities to the sea, like whispering, creating personification.
3. Which of the following is NOT a part of a plant cell?
- A. Cell wall
- B. Plasma membrane
- C. Vacuole
- D. Mitochondria
Correct answer: D
Rationale: Rationale: A) Cell wall: This is a structure found in plant cells that provides support and protection. B) Plasma membrane: Also known as the cell membrane, it surrounds the cell and regulates the passage of substances in and out of the cell. C) Vacuole: This is a storage organelle found in plant cells that stores water, nutrients, and waste products. D) Mitochondria: Mitochondria are membrane-bound organelles found in both plant and animal cells. They are responsible for producing energy in the form of ATP through cellular respiration. Therefore, the correct answer is D) Mitochondria, as it is a part of a plant cell.
4. Which of the following units is equivalent to a joule?
- A. Newton-meter (N·m)
- B. Watt (W)
- C. Kilogram (kg)
- D. Ampere (A)
Correct answer: a
Rationale: A joule, as a unit of energy, is equivalent to a newton-meter in terms of work or energy.
5. What are the building blocks of proteins?
- A. Sugars
- B. Fatty acids
- C. Amino acids
- D. Nucleotides
Correct answer: C
Rationale: Rationale: Proteins are macromolecules made up of long chains of amino acids. Amino acids are the building blocks of proteins and are linked together through peptide bonds to form polypeptide chains, which then fold into specific three-dimensional structures to carry out various functions in the body. Sugars (A) are the building blocks of carbohydrates, fatty acids (B) are the building blocks of lipids, and nucleotides (D) are the building blocks of nucleic acids like DNA and RNA.
6. Which blood vessels carry deoxygenated blood from the body back to the right atrium of the heart?
- A. Arteries
- B. Veins
- C. Capillaries
- D. Venules
Correct answer: B
Rationale: The correct answer is B: Veins. Veins are the blood vessels that carry deoxygenated blood from the body back to the heart. Arteries carry oxygenated blood away from the heart, while capillaries are tiny blood vessels where exchange of gases and nutrients occurs. Venules are small blood vessels that collect blood from capillaries and carry it to veins. Understanding the role of veins in carrying deoxygenated blood is crucial for comprehending the circulatory system and how blood is circulated throughout the body.
