1. What is the process of removing waste products from the cell called?

• A. Exocytosis
• B. Endocytosis
• C. Phagocytosis
• D. Pinocytosis

Correct answer: A

Rationale: Rationale: A) Exocytosis is the process by which cells expel waste products or other substances by fusing a vesicle containing the waste with the cell membrane, releasing its contents outside the cell. This process is essential for maintaining cellular homeostasis by removing waste products from the cell. B) Endocytosis is the process by which cells take in substances by engulfing them in a vesicle formed from the cell membrane. This process is the opposite of exocytosis and is used to bring substances into the cell. C) Phagocytosis is a type of endocytosis where cells engulf solid particles or other cells to form a vesicle called a phagosome. This process is used by immune cells to engulf and destroy pathogens. D) Pinocytosis is a type of endocytosis where cells engulf fluids and dissolved solutes. This process allows cells to take in nutrients and

2. Katherine is a young Unit Manager of the Pediatric Ward. Most of her staff nurses are senior

• A. Identify the source of the conflict and understand the points of friction
• B. Disregard what she feels and continue to work independently
• C. Seek help from the Director of Nursing
• D. Quit her job and look for another employment.

Correct answer: C

Rationale: The correct answer is C: Seek help from the Director of Nursing. As a young Unit Manager managing a team of senior staff nurses, Katherine may face challenges in leading and gaining the respect of her team due to the age and experience gap. Seeking help from the Director of Nursing can provide her with guidance, mentorship, and support in navigating these challenges. It is important for Katherine to communicate openly about any conflicts or issues she may be facing in order to address them effectively and maintain a positive work environment. Quitting her job (option D) should be considered as a last resort after exhausting all other possible solutions.

3. Which of the following situations represents work being done on an object?

• A. Pushing against a wall without moving it
• B. Carrying a heavy object without lifting it
• C. Lifting a box to place it on a shelf
• D. Holding a book stationary in your hand

Correct answer: c

Rationale: Work is done when a force is applied to move an object over a distance.

4. How can the periodic table be used to predict the charge of an ion formed by an element?

• A. Look for elements with similar atomic weights.
• B. Identify the group number, which corresponds to the typical ionic charge.
• C. Calculate the difference between protons and electrons.
• D. Analyze the element's position within the period.

Correct answer: B

Rationale: Identify the group number, which corresponds to the typical ionic charge. Elements tend to gain or lose electrons to achieve a stable electron configuration like the noble gas group. Their group number often indicates the number of electrons gained/lost and the resulting ionic charge.

5. Urine travels from the kidneys to the bladder through tubes called:

• A. Urethra
• B. Ureters
• C. Renal arteries
• D. Renal veins

Correct answer: B

Rationale: The correct answer is B: Ureters. The ureters are the tubes that carry urine from the kidneys to the bladder. The renal arteries and renal veins are blood vessels that supply and drain blood from the kidneys, respectively. The urethra is the tube that carries urine from the bladder out of the body. Understanding the anatomy of the urinary system is important for grasping how waste is processed and eliminated by the body.

6. In a single displacement reaction, one element takes the place of another element in a compound. Which of the following is an example?

• A. 2H2 + O2 -> 2H2O
• B. Zn + 2HCl -> ZnCl2 + H2
• C. CaCO3 -> CaO + CO2
• D. CH4 + 2O2 -> CO2 + 2H2O

Correct answer: B

Rationale: In a single displacement reaction, one element replaces another element in a compound. Option B, 'Zn + 2HCl -> ZnCl2 + H2,' is an example of a single displacement reaction where zinc (Zn) replaces hydrogen (H) in hydrochloric acid (HCl) to form zinc chloride (ZnCl2) and hydrogen gas (H2). The other options do not involve one element displacing another in a compound. Option A is a synthesis reaction, option C is a decomposition reaction, and option D is a combustion reaction. Therefore, option B is the correct answer as it demonstrates the concept of single displacement reactions.
