At which angle should residents be positioned for eating?

Correct Answer: D

Rationale: The correct angle for residents to be positioned for eating is 90 degrees. This allows for optimal upright posture and aids in swallowing and digestion. Sitting at 90 degrees helps prevent choking and aspiration. Choice A (180 degrees) is lying flat, which increases the risk of choking. Choices B (120 degrees) and C (100 degrees) are not optimal angles for proper swallowing and digestion, leading to potential health issues.

Correct Answer: B

Rationale: The correct answer is B: Genital herpes. Genital herpes is a viral infection caused by the herpes simplex virus (HSV) and cannot be cured with antibiotics. The virus remains in the body for life and can cause repeated outbreaks. Antibiotics are ineffective against viruses. Chlamydia, gonorrhea, and syphilis are bacterial infections that can be treated and cured with antibiotics. Therefore, option B is the correct answer.

Correct Answer: D

Rationale: The correct answer is D, as the circulatory system transports oxygen and hormones to cells. This function is essential for cellular respiration and maintaining homeostasis. Option A is incorrect as sensing and interpreting information is the role of the nervous system. Option B is incorrect as cushioning the brain and spinal cord falls under the protection provided by the skeletal system. Option C is incorrect as reproduction is primarily controlled by the reproductive system, not the circulatory system.

Correct Answer: B

Rationale: The correct answer is B: Atrophy. Atrophy refers to the weakening, wasting away, and decrease in size of a muscle due to disuse or disease. Dystrophy (A) is a genetic disorder affecting muscle development. Contracture (C) is the shortening or tightening of muscles, not wasting away. Dislocation (D) is the displacement of bones at a joint, not related to muscle wasting. In this context, atrophy best describes the specific condition of muscle weakening and decrease in size.

Correct Answer: A

Rationale: The correct answer is A because using the face of an imaginary clock helps individuals with visual impairments understand object positions based on the clock's face. This technique provides a consistent reference point for describing directions and locations. Choice B is incorrect because keeping the room dark can further hinder the individual's vision. Choice C is incorrect as it can startle or make the individual uncomfortable. Choice D is incorrect as touching the resident before identifying yourself can be invasive and disorienting.
