1. As a nursing student triaging a patient, which of the following is an example of quantitative data you can gather?

• A. The patient says he feels pain.
• B. The patient says he has stabbing pain.
• C. The patient's temperature is 101.7°F.
• D. The patient reports that he had a fever yesterday.

Correct answer: C

Rationale: The corrected choice C, 'The patient's temperature is 101.7°F,' is an example of quantitative data because it provides a specific numerical value that can be measured. Quantitative data involves measurable and numerical information, making it crucial for assessing a patient's condition objectively. Choices A and B are subjective statements based on the patient's perception of pain and its description, which are qualitative data and may vary between individuals. Choice D provides historical information about a fever, which is not a current measurable value and does not constitute quantitative data for immediate assessment.

2. Adipose tissue, also known as fat, serves multiple functions. Which of these is NOT a function of adipose tissue?

• A. Insulation
• B. Energy storage
• C. Hormone production
• D. Muscle movement

Correct answer: D

Rationale: Adipose tissue serves multiple functions in the body, including insulation to regulate body temperature, energy storage in the form of triglycerides, and hormone production such as leptin and adiponectin. Adipose tissue does not directly participate in muscle movement. Muscle movement is primarily carried out by skeletal muscle tissue, which is responsible for voluntary movements and locomotion. Therefore, the correct answer is D, as adipose tissue is not involved in muscle movement.

3. Which dome-shaped muscular structure separates the chest cavity from the abdominal cavity?

• A. Diaphragm
• B. Sternum
• C. Pericardium
• D. Trachea

Correct answer: A

Rationale: The diaphragm is the correct answer. It is a dome-shaped muscular structure that separates the chest cavity from the abdominal cavity. The diaphragm plays a crucial role in breathing by contracting and relaxing to change thoracic volume during inhalation and exhalation. The sternum is a flat bone in the center of the chest and is not the structure that separates the chest and abdominal cavities. The pericardium is a membrane that surrounds the heart, not involved in separating cavities. The trachea is the windpipe that connects the larynx to the bronchi and is not the structure that separates the chest and abdominal cavities.

4. What is the primary function of hematopoietic tissue?

• A. Building and repairing bone
• B. Supporting and connecting tissues
• C. Production of blood cells
• D. Contracting for movement

Correct answer: C

Rationale: The primary function of hematopoietic tissue is the production of blood cells. Hematopoietic tissue, primarily found in the bone marrow, is responsible for generating red blood cells, white blood cells, and platelets. These blood cells are vital for oxygen transport, immune response, and blood clotting. Choices A, B, and D are incorrect as they do not reflect the main function of hematopoietic tissue. Building and repairing bone is primarily carried out by osteoblasts and osteoclasts, supporting and connecting tissues is a role of connective tissues like tendons and ligaments, and contracting for movement is a function of muscle tissue.

5. What is the main function of the nervous system?

• A. To fight infection
• B. To control body movement and coordination
• C. To regulate metabolism
• D. To transport oxygen

Correct answer: B

Rationale: The main function of the nervous system is to control body movement and coordination by transmitting signals between different parts of the body. Choice A is incorrect because the immune system, not the nervous system, is primarily responsible for fighting infections. Choice C is incorrect as regulating metabolism is primarily handled by the endocrine system. Choice D is incorrect because the transportation of oxygen is mainly the function of the circulatory system, specifically the blood.
