Correct Answer: A
Rationale: The correct answer is A because cleaning at least two inches of the catheter near the body helps prevent infection at the insertion site. This step ensures proper hygiene and reduces the risk of catheter-related complications. Rinsing the catheter (choice B) is not as effective as cleaning. Closing the clamp without cleaning (choice C) can lead to bacterial growth. Allowing the clamp to touch the graduate (choice D) can introduce contaminants. Cleaning the catheter near the body is the most essential step in catheter care.
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 exchange oxygen from the air we breathe with carbon dioxide produced by our cells. Oxygen is taken up by red blood cells in the lungs and transported to the body tissues, while carbon dioxide is released from the tissues into the bloodstream and then exhaled through the lungs. Nitrogen (choice A) is not involved in the gas exchange process. Hydrogen (choice B) is not a primary gas exchanged during respiration. Carbon monoxide (choice D) is a toxic gas that can interfere with oxygen transport but is not a normal part of the respiratory exchange process.
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 crucial component of the central nervous system, responsible for processing information, controlling bodily functions, and regulating emotions. It is the main organ that coordinates all activities in the body. 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 that controls involuntary bodily functions, such as heart rate and digestion, and is not part of the central nervous system.
Question 4 of 5
Which mineral required for proper thyroid gland function is found in common table salt?
Correct Answer: C
Rationale: The correct answer is C: Iodine. Iodine is essential for thyroid hormone production, which regulates metabolism. Common table salt is often iodized to prevent iodine deficiency. Potassium (A) is important for heart and muscle function, but not specifically for thyroid function. Magnesium (B) plays various roles in the body but is not directly related to thyroid function. Copper (D) is involved in enzyme function but is not a primary mineral for thyroid gland function.
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 activities. They can include wheelchairs, hearing aids, and adaptive tools. Orthotic devices (A) are used for support or alignment, not specifically for daily activities. Restorative devices (C) aim to improve function, not solely assist in daily living. Range of motion devices (D) focus on movement limitations, not daily tasks. Therefore, B is the best choice for devices aiding in daily living activities.
