1. Which hormone, produced by the pancreas, is released in response to low blood sugar levels and stimulates the release of glucose into the bloodstream?
- A. Insulin
- B. Glucagon
- C. Cortisol
- D. Thyroxine
Correct answer: b
Rationale: The correct answer is B: Glucagon. Glucagon is a hormone produced by the pancreas that is released in response to low blood sugar levels, also known as hypoglycemia. When blood sugar levels drop, glucagon acts to stimulate the liver to release stored glucose into the bloodstream, helping to raise blood sugar levels back to a normal range. Insulin, on the other hand, is released in response to high blood sugar levels and helps to lower blood sugar by promoting the uptake of glucose by cells. Cortisol is a stress hormone produced by the adrenal glands, and thyroxine is a hormone produced by the thyroid gland that regulates metabolism. Therefore, glucagon is the hormone specifically responsible for stimulating the release of glucose into the bloodstream in response to low blood sugar levels.
2. What is the significance of the nuclear envelope breaking down during mitosis?
- A. It allows the chromosomes to condense and become visible.
- B. It allows the spindle apparatus to form and attach to the chromosomes.
- C. It allows the sister chromatids to separate.
- D. It allows the nuclear material to be evenly distributed to the daughter cells.
Correct answer: B
Rationale: Rationale: A) The breakdown of the nuclear envelope does not directly cause the chromosomes to condense and become visible. Chromosome condensation is a separate process that occurs before mitosis begins. B) The breakdown of the nuclear envelope is crucial for the formation of the spindle apparatus, a structure made of microtubules that helps separate the chromosomes during cell division. The spindle apparatus attaches to the chromosomes and helps move them to opposite poles of the cell. C) The separation of sister chromatids occurs during anaphase, which is facilitated by the spindle apparatus. The breakdown of the nuclear envelope is not directly involved in this process. D) The even distribution of nuclear material to daughter cells is achieved through the movement of chromosomes by the spindle apparatus, which is made possible by the breakdown of the nuclear envelope.
3. The fundamental units of structure and function in all living organisms, including humans, are termed:
- A. Muscles
- B. Organs
- C. Tissues
- D. Cells
Correct answer: D
Rationale: The correct answer is D: Cells. Cells are the fundamental units of structure and function in all living organisms, including humans. They are the building blocks of life, performing various functions necessary for an organism to survive and thrive. Muscles (A) are composed of muscle tissue, which is made up of muscle cells. Organs (B) are structures made up of different types of tissues working together. Tissues (C) are groups of cells that work together to perform specific functions within an organism. However, cells are the smallest unit of life and are responsible for carrying out all the essential processes needed for an organism to function.
4. Which type of orbital can hold a maximum of 10 electrons?
- A. s orbital
- B. p orbital
- C. d orbital
- D. f orbital
Correct answer: D
Rationale: Each f orbital can hold up to 2 electrons, and there are 5 f orbitals, totaling a maximum of 10 electrons.
5. Urine, the liquid waste product of the body, travels from the kidneys to the bladder through tubes called:
- A. Ureters
- B. Urethra
- C. Nephrons
- D. Renal pelvis
Correct answer: A
Rationale: The correct answer is A: Ureters. Ureters are the tubes that connect the kidneys to the bladder, allowing urine to flow from the kidneys to the bladder for storage before elimination. The urethra, option B, is the tube through which urine is expelled from the bladder out of the body. Nephrons, option C, are the functional units of the kidneys responsible for filtering blood and producing urine. The renal pelvis, option D, is a part of the kidney where urine collects before entering the ureters. Therefore, the correct answer is A, as the ureters specifically carry urine from the kidneys to the bladder.
6. When Harry uses team nursing as a care delivery system, he and his team need to assess the
- A. Each patient as listed on the worksheet
- B. Patients who needs least care
- C. Medications and treatments required for all patients
- D. Patients who need the most care
Correct answer: C
Rationale: When Harry uses team nursing as a care delivery system, he and his team need to assess the medications and treatments required for all patients. In team nursing, different team members are responsible for specific aspects of patient care, such as medications and treatments. Assessing the medications and treatments required for all patients ensures that each patient receives appropriate and timely care. This approach helps in coordinating care effectively among team members and prevents errors or omissions in patient treatment. Therefore, option C is the correct answer as it aligns with the principles of team nursing and patient-centered care.
