1. What property of matter refers to the force of gravity acting on an object?

• A. Mass
• B. Weight
• C. Density
• D. Volume

Correct answer: b

Rationale: Weight is the measure of the force of gravity acting on an object. It is calculated as mass multiplied by the acceleration due to gravity.

2. Which of the following is a condition characterized by a loss of bone density and increased risk of fractures?

• A. Osteoarthritis
• B. Rickets
• C. Osteoporosis
• D. Scoliosis

Correct answer: C

Rationale: The correct answer is C: Osteoporosis. Osteoporosis is a condition characterized by a loss of bone density, which leads to weakened bones and an increased risk of fractures. Osteoarthritis (A) is a degenerative joint disease, not a bone density issue. Rickets (B) is a disorder caused by a deficiency of vitamin D, leading to soft and weak bones, mainly seen in children. Scoliosis (D) is a condition characterized by an abnormal curvature of the spine, not directly related to bone density loss. Understanding the differences between these conditions is important for diagnosing and treating patients accurately.

3. What kind of lens focuses parallel light rays to a single point?

• A. Concave lens
• B. Convex lens
• C. Cylindrical lens
• D. Plano lens

Correct answer: B

Rationale: Convex lenses (converging lenses) bend incoming light rays inwards, focusing them to a point called the focal point.

4. The Merkel cells, located in the epidermis, are specialized for:

• A. Melanin production
• B. Temperature sensation
• C. Touch perception
• D. Immune defense

Correct answer: C

Rationale: The correct answer is C: 'Touch perception.' Merkel cells, also known as Merkel discs, are found in the skin's epidermal layer and are responsible for sensing touch. These cells are located near nerve endings and help detect light touch and pressure on the skin. They play a crucial role in the perception of tactile sensations and are not involved in melanin production, temperature sensation, or immune defense. Therefore, the specialized function of Merkel cells is primarily related to touch perception, making option C the correct choice.

5. During sexual intercourse, sperm travels through a tube from the testes to the urethra. What is the name of this tube?

• A. Vas deferens
• B. Epididymis
• C. Seminal vesicle
• D. Urethra

Correct answer: A

Rationale: The correct answer is A: 'Vas deferens.' The vas deferens is a tube that carries sperm from the testes to the urethra during ejaculation. It is a crucial part of the male reproductive system, allowing for the transport of sperm for fertilization. The epididymis is where sperm mature and are stored, not where they travel during intercourse. The seminal vesicle is a gland that produces a significant portion of the seminal fluid. The urethra is the tube that carries both urine and semen out of the body but is not where sperm travels from the testes.

6. 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.
