1. Tissues are groups of cells with similar:

• A. Appearance only
• B. Function and structure
• C. Location only
• D. Age only

Correct answer: B

Rationale: Tissues are groups of cells that work together to perform a specific function. They have similar structures that enable them to carry out their specialized functions effectively. Therefore, tissues are defined by both their function and structure, making option B the correct choice. Choices A, C, and D are incorrect because tissues are not solely defined by their appearance, location, or age, but rather by the shared function and structure of the cells within them.

2. What is the bottom number in a blood pressure reading?

• A. Diastolic pressure
• B. Systolic pressure
• C. Pulse rate
• D. Mean arterial pressure

Correct answer: A

Rationale: The correct answer is A: Diastolic pressure. The bottom number in a blood pressure reading represents the diastolic pressure, which indicates the lowest pressure in the arteries when the heart is resting between beats. This value is important in understanding the overall health of the cardiovascular system. Choice B, Systolic pressure, is the top number in a blood pressure reading and represents the pressure in the arteries when the heart is contracting. Choice C, Pulse rate, refers to the number of times the heart beats in a minute. Choice D, Mean arterial pressure, is a calculated value using both systolic and diastolic pressures to provide an average pressure in the arteries during a cardiac cycle, but it is not the bottom number in a blood pressure reading.

3. What is the term for a group of organisms with the same genetic makeup?

• A. Population
• B. Clone
• C. Genotype
• D. Species

Correct answer: B

Rationale: In this context, a clone (option B) is a group of organisms that are genetically identical because they are derived from a single ancestor. A population (option A) refers to a group of individuals of the same species living in the same area. Genotype (option C) refers to the genetic makeup of an individual organism. Species (option D) refers to a group of organisms that can interbreed and produce fertile offspring. Therefore, the most appropriate choice for the question is 'Clone,' as it specifically refers to organisms with the same genetic makeup.

4. Identify the correct sequence of the 3 primary body planes as numbered 1, 2, and 3 in the above image.

• A. Plane 1 is coronal, plane 2 is sagittal, and plane 3 is transverse.
• B. Plane 1 is sagittal, plane 2 is coronal, and plane 3 is medial.
• C. Plane 1 is coronal, plane 2 is sagittal, and plane 3 is medial.
• D. Plane 1 is sagittal, plane 2 is coronal, and plane 3 is transverse.

Correct answer: A

Rationale: In the standard anatomical position, plane 1 (coronal/frontal plane) divides the body into anterior and posterior portions, plane 2 (sagittal plane) divides the body into left and right portions, and plane 3 (transverse/horizontal plane) divides the body into superior and inferior portions. Therefore, the correct sequence is Plane 1 as coronal, Plane 2 as sagittal, and Plane 3 as transverse, which corresponds to Choice A. Choice B is incorrect as it misidentifies the planes. Plane 2 cannot be coronal as it specifically divides the body into left and right portions. Choice C is incorrect as it misidentifies Plane 2 as sagittal when it should be coronal. Choice D is incorrect as it incorrectly designates Plane 2 as coronal when it should be sagittal, leading to an inaccurate sequence of the primary body planes.

5. Which term refers to the act of inhaling foreign objects into the airway?

• A. Expiration
• B. Respiration
• C. Aspiration
• D. Inhalation

Correct answer: C

Rationale: Among the options provided, aspiration is the term that specifically refers to the act of inhaling foreign objects into the airway. Expiration refers to breathing out, respiration is the overall process of gas exchange in the body, and inhalation is the act of breathing in air or other substances into the lungs. Therefore, the correct answer is C, aspiration. It is crucial to understand these terms in the context of airway management and respiratory care to ensure proper identification and treatment of related conditions.
