1. The lymphatic system is a network of vessels and organs that plays a vital role in:
- A. Transporting oxygen and nutrients to cells
- B. Carrying waste products away from tissues
- C. Regulating body temperature
- D. Producing red blood cells
Correct answer: B
Rationale: The correct answer is B: Carrying waste products away from tissues. The lymphatic system is responsible for collecting excess fluid and waste products from tissues and returning them to the bloodstream for removal. This helps maintain fluid balance in the body and supports immune function by transporting white blood cells to fight infections. Options A, C, and D do not accurately describe the function of the lymphatic system. Transporting oxygen and nutrients to cells is primarily the role of the circulatory system, while regulating body temperature is controlled by the nervous system and producing red blood cells occurs in the bone marrow.
2. The statement, “The Good Shepherd Medical Center aims to provide patient-centered care in
- A. Vision
- B. Goal
- C. Philosophy
- D. Mission
Correct answer: A
Rationale: The correct answer is A: "Vision." A vision statement describes the desired future state or long-term goal of an organization. It outlines the aspirations and purpose of the organization, such as providing patient-centered care in this case. Vision statements are forward-looking and inspirational, guiding the organization towards achieving its ultimate objectives. In contrast, a goal is a specific, measurable, and achievable target within a set timeframe. A philosophy is a set of beliefs or guiding principles, while a mission statement defines the organization's core purpose and focus. Therefore, the statement about providing patient-centered care aligns with the concept of a vision statement.
3. Which of the following terms refers to a muscle twitch, a single forceful contraction of a muscle fiber?
- A. Tetanus
- B. Trembling
- C. Fasciculation
- D. Rigidity
Correct answer: C
Rationale: The correct answer is C: "Fasciculation." A muscle twitch refers to the involuntary contraction of a small group of muscle fibers. Tetanus (choice A) is a sustained contraction of a muscle caused by rapid stimulation. Trembling (choice B) is the shaking or quivering of muscles. Rigidity (choice D) refers to stiffness or inflexibility in muscles. Fasciculation is the term that specifically describes a muscle twitch, which is a single forceful contraction of a muscle fiber. Therefore, choice C is the most appropriate term for this scenario.
4. Which of the following factors would increase the solubility of a gas in a liquid?
- A. Decreasing temperature
- B. Increasing pressure
- C. Decreasing surface area
- D. Increasing particle size
Correct answer: b
Rationale: Henry's law states that the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid. The other choices would typically decrease solubility.
5. What is the scientific name for the building blocks of proteins?
- A. Residues
- B. Monomers
- C. Macromolecules
- D. Peptides
Correct answer: B
Rationale: Rationale: - Proteins are made up of long chains of amino acids. - Amino acids are the building blocks of proteins and are considered monomers. - Monomers are the individual units that can be linked together to form larger molecules called polymers. - In the context of proteins, amino acids are the monomers that are linked together through peptide bonds to form polypeptide chains, which then fold into functional proteins. - Residues refer to the specific amino acids within a protein after certain modifications or cleavages have occurred, so it is not the correct term for the building blocks of proteins. - Macromolecules are large molecules made up of smaller subunits, such as proteins, nucleic acids, and carbohydrates, but they are not the specific building blocks of proteins. - Peptides are short chains of amino acids linked by peptide bonds, but they are not the fundamental building blocks of proteins.
6. What does the term "solute" refer to in a solution?
- A. The substance present in the largest amount
- B. The substance that dissolves in the solvent
- C. The liquid portion of the solution
- D. The temperature at which the solution freezes
Correct answer: B
Rationale: The solute is the substance that dissolves in the solvent to form a solution. The other choices do not accurately describe the solute.
