Question 1 of 5
One important step in catheter care is for the nursing assistant to
Correct Answer: A
Rationale: The correct answer is A because cleaning at least two inches of the catheter near the body helps prevent infection by removing bacteria that can travel up the catheter. Cleaning a larger area reduces the risk of contamination. Choice B is incorrect because rinsing the catheter does not effectively clean it, and focusing on the nearest four inches may not address the area most prone to contamination. Choice C is incorrect because closing and replacing the clamp without cleaning it can introduce bacteria into the catheter system, increasing the risk of infection. Choice D is incorrect because allowing the catheter clamp to touch the graduate can lead to contamination and potential infection.
Question 2 of 5
The lungs are the main organs of respiration and are responsible for the exchange of oxygen and
Correct Answer: C
Rationale: The correct answer is C: Carbon dioxide. The lungs facilitate the exchange of oxygen and carbon dioxide during respiration. Oxygen is taken in, and carbon dioxide is expelled from the body through breathing. Carbon dioxide is a waste product produced by cells during cellular respiration. Choices A, B, and D are incorrect because nitrogen is not directly involved in the respiratory process, hydrogen is not a major component of respiration, and carbon monoxide is a toxic gas that interferes with oxygen transport in the body.
Question 3 of 5
One part of the central nervous system is the
Correct Answer: A
Rationale: The correct answer is A: Brain. The brain is a vital component of the central nervous system that processes information, controls actions, and regulates bodily functions. It receives and interprets signals from nerves, eyes, and ears. Nerves (choice B) are part of the peripheral nervous system, not the central nervous system. Eyes and ears (choice C) are sensory organs that transmit information to the brain but are not part of the central nervous system. The autonomic nervous system (choice D) is a division of the peripheral nervous system responsible for involuntary bodily functions.
Question 4 of 5
Which mineral required for proper thyroid gland function is found in common table salt?
Correct Answer: C
Rationale: Rationale: 1. Iodine is essential for thyroid hormone synthesis. 2. Thyroid hormones regulate metabolism, growth, and development. 3. Common table salt is often iodized to prevent iodine deficiency. 4. Potassium, Magnesium, and Copper do not play a direct role in thyroid function. Summary: - Choice A, Potassium, is important for heart and muscle function. - Choice B, Magnesium, is crucial for nerve and muscle function. - Choice D, Copper, is needed for red blood cell production.
Question 5 of 5
A type of device used to help a disabled person perform activities of daily living is a(n)
Correct Answer: B
Rationale: The correct answer is B: Assistive device. Assistive devices are designed to help disabled individuals perform daily tasks independently. They can range from simple tools to complex technology. Orthotic devices (A) provide support or correct alignment, not necessarily for daily tasks. Restorative devices (C) aim to restore function rather than assist in daily living. Range of motion devices (D) focus on improving mobility, not specifically aiding in daily activities. Therefore, B is the best choice for devices that facilitate activities of daily living for disabled individuals.
