1. What is the law of conservation of energy?

• A. Energy cannot be created, only destroyed
• B. Energy can be created but not destroyed
• C. Energy can neither be created nor destroyed, only transformed from one form to another
• D. Energy is always created in any process

Correct answer:

Rationale: According to the law of conservation of energy, the total energy in a closed system remains constant; it can change forms but cannot be created or destroyed.

2. Ms. Valencia develops the standards to be followed. Among the following standards, which is

• A. The patients verbalized satisfaction of the nursing care received
• B. Rotation of duty will be done every four weeks for all patient care personnel.
• C. All patients shall have their weights taken recorded
• D. Patients shall answer the evaluation form before discharge

Correct answer: C

Rationale: The correct answer is C because it is a clear and specific standard that can be easily measured and monitored. Weight recording is a fundamental aspect of patient care and is essential for tracking changes in health status. Verbalized satisfaction (option A) is subjective and may not be consistently measurable. Rotation of duty (option B) is important but may not be a standard developed by a nurse manager. Answering an evaluation form before discharge (option D) is important but may not be a standard created by Ms. Valencia for all patients.

3. Muscle tissue is responsible for movement. Which type of muscle tissue is found in the heart?

• A. Skeletal muscle
• B. Smooth muscle
• C. Cardiac muscle
• D. All of the above

Correct answer: C

Rationale: The correct answer is C: Cardiac muscle. Cardiac muscle is a specialized type of muscle tissue found in the heart. Unlike skeletal muscle, which is under voluntary control, and smooth muscle, which is found in the walls of internal organs and blood vessels, cardiac muscle is involuntary and responsible for the rhythmic contractions of the heart to pump blood throughout the body. Therefore, cardiac muscle is the specific type of muscle tissue found in the heart, making it the correct choice for this question.

4. Which of the following substances is typically a good conductor of electricity when dissolved in water?

• A. Sugar
• B. Sodium chloride
• C. Olive oil
• D. Oxygen gas

Correct answer: b

Rationale: Ionic compounds like sodium chloride dissociate into ions in water, making the solution conductive. The other choices do not typically conduct electricity in water.

5. Cystitis is an inflammation of the:

• A. Kidneys
• B. Bladder
• C. Ureters
• D. Urethra

Correct answer: B

Rationale: The correct answer is B: Bladder. Cystitis is an inflammation of the bladder, typically caused by a bacterial infection. Symptoms include frequent and urgent urination, along with pain or discomfort in the pelvic area. The kidneys (option A) are responsible for filtering blood and producing urine, but they are not the site of inflammation in cystitis. The ureters (option C) are the tubes that connect the kidneys to the bladder and are not typically affected by cystitis. The urethra (option D) is the tube that carries urine from the bladder out of the body, but it is not where the inflammation occurs in cystitis.

6. Which component of the nervous system is responsible for controlling voluntary movements, such as the contraction of skeletal muscles?

• A. Autonomic nervous system
• B. Peripheral nervous system
• C. Somatic nervous system
• D. Sympathetic nervous system

Correct answer: c

Rationale: The correct answer is C, the somatic nervous system. The somatic nervous system is responsible for controlling voluntary movements, such as the contraction of skeletal muscles. This system consists of motor neurons that send signals from the central nervous system to the skeletal muscles, allowing us to consciously control our movements. The autonomic nervous system (A) controls involuntary actions like heart rate and digestion, the peripheral nervous system (B) includes all nerves outside of the brain and spinal cord, and the sympathetic nervous system (D) is a division of the autonomic nervous system responsible for the fight-or-flight response. Therefore, the somatic nervous system is specifically involved in voluntary movements.
