1. Ms. Valencia prepares the process standards. Which of the following is NOT a process
- A. Initial assessment shall be done to all patients within twenty four hours upon admission.
- B. Informed consent shall be secured prior to any invasive procedure
- C. Patients’ reports 95% satisfaction rate prior to discharge from the hospital.
- D. Patient education about their illness and treatment shall be provided for all patients and their
Correct answer: D
Rationale: In this question, Ms. Valencia is tasked with preparing process standards, which are systematic procedures or steps followed to ensure quality care. Options A, B, and C all refer to specific processes that are essential in healthcare: timely assessment, obtaining informed consent, and assessing patient satisfaction. However, option D about providing patient education is more focused on an outcome (patient education) rather than a specific process standard. While patient education is important, the question is asking for a process standard, making option D the correct answer as it does not directly relate to a specific process standard.
2. What is the primary difference between ionic and metallic bonding?
- A. Ionic bonds involve electron sharing, while metallic bonds involve electron transfer.
- B. Ionic bonds are weak and directional, while metallic bonds are strong and non-directional.
- C. Ionic bonds exist between metals and non-metals, while metallic bonds exist only between metals.
- D. Ionic bonds form discrete molecules, while metallic bonds form extended structures.
Correct answer: B
Rationale: Ionic bonds form discrete molecules, while metallic bonds form extended structures. Ionic bonds involve complete electron transfer between specific atoms, resulting in discrete molecules. Metallic bonds involve a "sea" of delocalized electrons shared across all metal atoms, leading to strong, non-directional bonding throughout the entire material.
3. Which hormone, produced by the thyroid gland, plays a crucial role in regulating the body's metabolism, growth, and development?
- A. Calcitonin
- B. Parathyroid hormone (PTH)
- C. Thyroxine
- D. Insulin
Correct answer: c
Rationale: The correct answer is C: Thyroxine. Thyroxine, also known as T4, is a hormone produced by the thyroid gland that plays a crucial role in regulating the body's metabolism, growth, and development. It controls how the body uses energy, affects heart rate, and influences other vital functions. Calcitonin (A) is involved in calcium regulation, not metabolism. Parathyroid hormone (PTH) (B) is produced by the parathyroid glands and regulates calcium and phosphorus levels in the body. Insulin (D) is a hormone produced by the pancreas that regulates blood sugar levels, not metabolism or growth.
4. A ball is thrown upwards. At the peak of its trajectory, which of the following forces is acting on the ball?
- A. Gravity only
- B. Gravity and air resistance only
- C. Neither gravity nor air resistance
- D. All of the above
Correct answer: C
Rationale: At the peak of its trajectory, the ball has momentarily stopped moving upwards and has not yet started to fall back down. Therefore, there is no longer a net force acting on the ball at that instant. Gravity is acting downwards, but since the ball is not moving, the force of gravity is balanced by an equal and opposite force, resulting in a net force of zero. Similarly, air resistance only affects the ball when it is in motion, so at the peak where the ball momentarily stops, there is no air resistance force. Therefore, at the peak of its trajectory, neither gravity nor air resistance is acting on the ball, making option C the correct answer.
5. Which of the following is NOT a type of vaccine?
- A. Live attenuated vaccine
- B. Toxoid vaccine
- C. Conjugate vaccine
- D. Antibiotic
Correct answer: D
Rationale: Rationale: A) Live attenuated vaccine: This type of vaccine contains a weakened form of the virus or bacteria that causes the disease. When administered, it stimulates an immune response without causing the disease itself. B) Toxoid vaccine: Toxoid vaccines are made from toxins produced by bacteria that have been inactivated. They stimulate the immune system to produce antibodies against the toxin, providing immunity against the disease. C) Conjugate vaccine: Conjugate vaccines are made by combining a weak antigen with a strong antigen to enhance the immune response. They are commonly used to protect against bacterial infections. D) Antibiotic: Antibiotics are medications used to treat bacterial infections by killing or inhibiting the growth of bacteria. They are not a type of vaccine but rather a class of antimicrobial drugs. Therefore, the correct answer is D) Antibiotic, as it is not a type of vaccine.
6. The involuntary reflex arc that withdraws your hand from a hot object involves the:
- A. Central nervous system only
- B. Peripheral nervous system only
- C. Both CNS and PNS
- D. Sensory neurons only
Correct answer: C
Rationale: The correct answer is C: 'Both CNS and PNS'. This is because the reflex arc involves both the central nervous system (CNS) and the peripheral nervous system (PNS). The sensory neurons in the PNS detect the stimulus (hot object), then send signals to the spinal cord in the CNS. The spinal cord processes the information and immediately sends a motor response signal back out through the PNS to move the hand away from the hot object. This rapid and involuntary response demonstrates the coordination between the CNS and PNS in executing the reflex arc.
