Which of the following is one of the functions that the circulatory system performs?

Correct Answer: D

Rationale: The correct answer is D: Transports oxygen and hormones to cells. The circulatory system includes the heart, blood vessels, and blood. The main function is to transport oxygen and nutrients to cells and remove waste products. Oxygen is carried by red blood cells, while hormones are transported in the bloodstream. A: Senses and interprets information from the environment - This function is carried out by the nervous system, particularly the sensory organs like eyes and ears. B: Cushions the brain and spinal cord - This function is performed by the cerebrospinal fluid and protective structures like the skull and vertebrae. C: Allows humans to reproduce - Reproduction is controlled by the reproductive system, not the circulatory system. In summary, the circulatory system's primary function is to transport oxygen and hormones to cells, making option D the correct choice.

Correct Answer: A

Rationale: The correct answer is A because using the face of an imaginary clock to explain object positions is a helpful technique for individuals with visual impairments to understand spatial relationships. This method is clear and easy to visualize, making it effective in communication. It promotes independence and enhances the person's understanding of their surroundings. Explanation of why other choices are incorrect: B: Keeping the room dark can further hinder the individual's ability to see and navigate their environment. C: Walking behind the resident and touching their back can startle or make them uncomfortable. It's important to offer support from the side to maintain their sense of safety. D: Touching the resident before identifying yourself can be alarming and invade their personal space. It's crucial to introduce yourself first to establish trust and ensure clear communication.

Correct Answer: B

Rationale: The correct answer is B: Problems with circulation. Diabetes can lead to complications such as peripheral artery disease and neuropathy, which can impair blood flow and sensation in the extremities. This can result in poor wound healing, infections, and even amputations. Chronic cough (A), lack of appetite (C), and improved ability to perform strenuous exercise (D) are not directly associated with diabetes-related complications.

Correct Answer: A

Rationale: The correct answer is A because orthotic devices are designed to keep joints in the correct position and improve function. This helps in supporting and stabilizing the body part, aiding in movement and reducing pain. Choice B is incorrect as orthotic devices are not specifically used to assist with activities of daily living (ADLs). Choice C is incorrect as maintaining proper body alignment is not the primary goal of orthotic devices. Choice D is also incorrect as preventing rubbing and pressure injuries is more related to proper fitting and usage of orthotic devices rather than their main purpose.

Correct Answer: A

Rationale: The correct answer is A: One page. A one-page resume is concise, easy to read, and keeps the hiring manager's attention. It forces the candidate to prioritize information, focusing on the most relevant and impactful details. Longer resumes may lose the reader's interest and dilute the key qualifications. Option B (Two pages) may contain unnecessary details, making it less effective. Option C (Three pages) is excessive and could be seen as unprofessional. Option D (As many pages as needed) lacks specificity and may result in a bloated resume. Ultimately, a one-page resume is succinct, impactful, and tailored to highlight the candidate's qualifications effectively.
