1. The peripheral nervous system can be further divided into which two main parts?

A. Sensory and motor
B. Sympathetic and parasympathetic
C. Myelinated and unmyelinated
D. Central and peripheral

Correct answer: A

Rationale: The correct answer is A: 'Sensory and motor.' The peripheral nervous system is divided into two main parts based on their functions. The sensory division (afferent) transmits sensory information from receptors to the central nervous system, while the motor division (efferent) transmits signals from the central nervous system to muscles and glands to produce a response. Options B, C, and D are incorrect as they do not accurately describe the main divisions of the peripheral nervous system. Understanding this division is crucial in comprehending how information is processed and responses are generated in the body.

2. What is the periodic law?

A. The statement that the properties of the elements are a periodic function of their atomic numbers.
B. The statement that the elements can be arranged in a table in which elements with similar properties are grouped together
C. The statement that the elements can be arranged in a table in which the atomic number of an element is equal to the number of protons in its nucleus
D. The statement that the elements can be arranged in a table in which the atomic mass of an element is equal to the number of neutrons in its nucleus.

Correct answer: A

Rationale: The periodic law states that the properties of elements are a periodic function of their atomic numbers. This means that when elements are arranged in order of increasing atomic number, there is a periodic repetition of their properties. This forms the basis for the modern periodic table. Option B describes the periodic table itself, while options C and D do not accurately describe the periodic law.

3. He discusses the goal of the department. Which of the following statements is a goal?

A. Increase the patient satisfaction rate
B. Eliminate the incidence of delayed administration of medications
C. Establish rapport with patients.
D. Reduce response time to two minutes.

Correct answer: A

Rationale: Option A, 'Increase the patient satisfaction rate,' is a goal because it represents an objective that the department aims to achieve. Patient satisfaction is a key indicator of quality care and reflects the department's commitment to providing excellent service. In contrast, options B, C, and D are more focused on specific actions or strategies rather than overarching goals. Eliminating delayed medication administration, establishing rapport with patients, and reducing response time are important tasks that may contribute to achieving the goal of increasing patient satisfaction, but they are not goals in themselves. Therefore, option A is the most appropriate choice as it directly addresses the department's ultimate objective of enhancing patient satisfaction.

4. Which state of matter has both definite volume and definite shape?

A. Solid
B. Liquid
C. Gas
D. Plasma

Correct answer: a

Rationale: Solids have both definite volume and definite shape. The particles in solids are closely packed, maintaining their positions, resulting in a fixed shape and volume.

5. The T wave on an ECG corresponds to:

A. Atrial depolarization
B. Ventricular depolarization
C. Atrial repolarization
D. Ventricular repolarization

Correct answer: D

Rationale: The T wave on an ECG corresponds to ventricular repolarization. During this phase, the ventricles are resetting electrically after contraction, preparing for the next heartbeat. Atrial depolarization is represented by the P wave, ventricular depolarization by the QRS complex, and atrial repolarization is typically hidden within the QRS complex. Therefore, option D, 'Ventricular repolarization,' is the correct choice when identifying the electrical activity represented by the T wave on an ECG.

6. What is the waste product of protein digestion?

A. Glucose
B. Amino acids
C. Fatty acids
D. Ammonia

Correct answer: D

Rationale: Rationale: Protein digestion involves breaking down proteins into their constituent amino acids. During this process, the waste product produced is ammonia. Ammonia is a toxic compound that needs to be converted into urea in the liver and then excreted by the kidneys in the form of urine. Glucose is a product of carbohydrate digestion, amino acids are the building blocks of proteins, and fatty acids are the end products of fat digestion.
