1. Which part of the brain is responsible for coordinating muscle movements, maintaining balance, and posture?
- A. Cerebrum
- B. Cerebellum
- C. Medulla oblongata
- D. Thalamus
Correct answer: b
Rationale: The correct answer is B: Cerebellum. The cerebellum is responsible for coordinating muscle movements, maintaining balance, and posture. It receives information from the sensory systems, the spinal cord, and other parts of the brain to regulate voluntary movements. The cerebrum, on the other hand, is mainly responsible for higher brain functions such as thinking and problem-solving. The medulla oblongata controls autonomic functions like breathing and heart rate, while the thalamus acts as a relay station for sensory information. Therefore, the cerebellum is the specific part of the brain that plays a crucial role in motor coordination and balance.
2. Which element is used in jewelry due to its malleability and resistance to tarnish?
- A. Iron
- B. Copper
- C. Gold
- D. Silver
Correct answer: C
Rationale: Gold's properties make it ideal for crafting durable and aesthetically pleasing jewelry
3. In the process of cellular respiration, glucose is broken down to produce energy. What is the main waste product released?
- A. Water
- B. Carbon dioxide
- C. Oxygen
- D. Protein
Correct answer: B
Rationale: The correct answer is B: Carbon dioxide. During cellular respiration, glucose is broken down in the presence of oxygen to produce energy in the form of ATP. One of the main waste products released in this process is carbon dioxide. Carbon dioxide is a byproduct of the metabolic reactions occurring in cells and is expelled from the body through exhalation. Water is also produced during cellular respiration, but it is not the main waste product released. Oxygen is required for cellular respiration to occur, and protein is a macromolecule and not a waste product of cellular respiration.
4. Which of the following guidelines should be least considered in formulating objectives for
- A. Written nursing care plan
- B. Holistic approach
- C. Prescribed standards
- D. Staff preferences
Correct answer: D
Rationale: When formulating objectives for a written nursing care plan, staff preferences should be least considered. Objectives should be based on patient needs, evidence-based practice, and professional standards rather than personal preferences of the staff. Prescribed standards ensure quality care and adherence to best practices. A holistic approach considers the whole patient, including physical, emotional, and spiritual aspects. Staff preferences may introduce bias and should not dictate patient care objectives.
5. Classifications of human tissues exclude:
- A. Epithelial tissue
- B. Nervous tissue
- C. Adipose tissue (a specialized form of connective tissue)
- D. Bony tissue
Correct answer: D
Rationale: The correct answer is D: 'Bony tissue.' Classifications of human tissues typically include four main types: epithelial, connective, muscular, and nervous tissue. Bony tissue, also known as osseous tissue, is a specialized form of connective tissue that forms bones in the skeletal system. While bony tissue is an essential component of the human body, it is not typically categorized separately as a distinct tissue type in general tissue classifications. Therefore, it is the exception from the list provided in the question, making it the correct answer.
6. What is the relationship between the speed of a wave, its frequency, and wavelength in a given medium?
- A. Speed = Frequency × Wavelength
- B. Speed = Frequency ÷ Wavelength
- C. Speed = Frequency + Wavelength
- D. Speed = Frequency - Wavelength
Correct answer: a
Rationale: In a given medium, the speed of a wave equals the product of its frequency and wavelength.
