Guidelines for serving meal trays include

Correct Answer: D

Rationale: The correct answer is D because saying positive things about the food being served can help promote a pleasant dining experience for residents, improve their appetite, and enhance their overall meal satisfaction. This positive reinforcement can also encourage residents to eat well and maintain good nutrition. In contrast, choices A, B, and C are incorrect because prioritizing residents based on need without considering their preferences may not promote individualized care, focusing solely on efficiency may compromise quality of care, and discouraging conversation during meals can diminish social interaction and enjoyment for residents.

Correct Answer: D

Rationale: The correct answer is D because as women age, the hormonal changes lead to a decrease in estrogen levels, resulting in the vaginal walls becoming drier and thinner. This is a normal age-related change known as vaginal atrophy. Lung capability increasing (A) and the amount of calcium in the body increasing (C) are not directly related to the female reproductive system. The response to vaccines decreasing (B) is more related to the immune system rather than the female reproductive system.

Correct Answer: B

Rationale: The correct answer is B: Aorta. The left ventricle pumps oxygen-rich blood into the aorta, which is the largest artery in the body and carries oxygenated blood to the rest of the body. This is a crucial step in the systemic circulation process. The other choices are incorrect because: A: Right ventricle - The right ventricle pumps deoxygenated blood to the lungs, not oxygen-rich blood. C: Capillaries - Capillaries are tiny blood vessels where gas exchange occurs between blood and tissues, not a site where blood is pumped. D: Veins - Veins carry blood back to the heart, with oxygen-poor blood returning to the right atrium, not the left ventricle.

Correct Answer: B

Rationale: The correct answer is B: Lending support to body structures. Bones provide structural support for the body, protect vital organs, and allow for movement. They also serve as storage for minerals and production of blood cells. Protecting the body from disease (A) is mainly the function of the immune system. Sending messages throughout the human body (C) is the role of the nervous system. Pumping blood throughout the body (D) is the function of the heart and circulatory system.

Correct Answer: B

Rationale: Paraplegia is the loss of function of the lower body and legs. "Para" means alongside or beside, indicating the lower part of the body. The other choices, A: Concussion, C: Quadriplegia, and D: Hemiplegia, do not specifically refer to the loss of function in the lower body and legs. Concussion is a head injury, Quadriplegia affects all four limbs, and Hemiplegia affects one side of the body.
