1. What happens to the wavelength of a wave when its frequency increases while the speed remains constant?

• A. Wavelength increases
• B. Wavelength decreases
• C. Wavelength remains the same
• D. Wavelength becomes zero

Correct answer: b

Rationale: When the frequency of a wave increases while the speed remains constant, the wavelength decreases.

2. Which pattern of nursing care involves the care given by a group of paraprofessional workers

• A. Case method
• B. Modular nursing
• C. Nursing case management
• D. Team nursing

Correct answer: A

Rationale: The correct answer is A: 'Case method.' The case method of nursing care involves the care provided by a group of paraprofessional workers, such as nursing assistants or aides, under the supervision of professional nurses. In this model, the nursing team works together to deliver care to a group of patients based on their specific needs and conditions. This method allows for efficient and coordinated care delivery, with each member of the team playing a crucial role in meeting the patients' healthcare needs. It is important for nurses to effectively delegate tasks and supervise paraprofessional workers in the case method model to ensure high-quality care and patient safety.

3. Percent Increase/Decrease: A medication dosage is increased by 20%. If the original dosage was 100mg, what is the new dosage?

• A. 80mg
• B. 100mg
• C. 120mg
• D. 140mg

Correct answer: C

Rationale: Multiply the original dosage (100mg) by 1 + the percentage increase (20% = 0.2) to get 120mg.

4. A 10 kg box rests on a frictionless surface. A horizontal force of 20 N is applied to the box. What is the box's acceleration?

• A. 0.5 m/s²
• B. 1 m/s²
• C. 2 m/s²
• D. 10 m/s²

Correct answer: C

Rationale: Use Newton's second law, F = ma, where F is the net force, m is the mass, and a is the acceleration. Since there is no friction, the net force equals the applied force (20 N). Therefore, a = F/m = 20 N / 10 kg ≈ 2 m/s².

5. How does the acceleration of an object change if the force acting on it is doubled?

• A. Acceleration is halved
• B. Acceleration doubles
• C. Acceleration remains unchanged
• D. Acceleration quadruples

Correct answer: b

Rationale: According to Newton's second law (F = ma), if force is doubled and mass remains constant, acceleration doubles.

6. Which of the following organs is NOT directly involved in urine production?

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

Correct answer: C

Rationale: The correct answer is C: Lungs. The lungs are not directly involved in urine production. The kidneys are responsible for filtering waste products from the blood to create urine. The urethra is the tube that carries urine from the bladder out of the body. The bladder serves as a temporary storage reservoir for urine. In contrast, the lungs are primarily responsible for the exchange of gases, such as oxygen and carbon dioxide, during respiration and are not directly involved in the process of urine production.
