1. 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.

2. Which of the following describes a vector quantity?

• A. Speed
• B. Distance
• C. Mass
• D. Velocity

Correct answer: d

Rationale: Velocity is a vector quantity as it includes both magnitude (speed) and direction.

3. Which of the following is NOT a part of the body's innate immune response?

• A. Physical barriers like skin and mucous membranes
• B. Phagocytes that engulf and destroy pathogens
• C. Inflammatory response to isolate and contain infection
• D. Production of antibodies specific to a particular pathogen

Correct answer: D

Rationale: The correct answer is D. The body's innate immune response is the first line of defense against pathogens, and it includes physical barriers like skin and mucous membranes (option A), phagocytes that engulf and destroy pathogens (option B), and the inflammatory response to isolate and contain infections (option C). The production of antibodies specific to a particular pathogen (option D) is part of the adaptive immune response, which develops over time and is not considered part of the innate immune system. Therefore, option D is not a component of the body's innate immune response.

4. A pressure vessel has a cylindrical body (diameter 10cm, height 20cm) with hemispherical ends (same diameter as the cylinder). What is its total surface area?

• A. 785 sq cm
• B. 1130 sq cm
• C. 1570 sq cm
• D. 2055 sq cm

Correct answer: D

Rationale: Calculate the surface area of the cylinder (base + lateral surface) and two hemispheres. Add them all up for the total surface area.

5. The important decision will be made tomorrow. Which word is the comparative form of the adjective "important"?

• A. important
• B. importantly
• C. more important
• D. most important

Correct answer: C

Rationale: The comparative form of an adjective compares two things.

6. Which of the following structures is responsible for preventing the backflow of blood from the left ventricle into the left atrium?

• A. Aortic valve
• B. Pulmonary valve
• C. Tricuspid valve
• D. Mitral valve

Correct answer: D

Rationale: The correct answer is D, the mitral valve. The mitral valve, also known as the bicuspid valve, is located between the left atrium and the left ventricle. Its main function is to prevent the backflow of blood from the left ventricle into the left atrium during ventricular contraction. The aortic valve (A) is responsible for preventing the backflow of blood from the aorta into the left ventricle, the pulmonary valve (B) prevents backflow from the pulmonary artery into the right ventricle, and the tricuspid valve (C) prevents backflow from the right ventricle into the right atrium. Therefore, the mitral valve is specifically responsible for preventing backflow in the left side of the heart, making it the correct answer in this case.
