How often must mouth care be provided for residents?

Correct Answer: B

Rationale: The correct answer is B: At least twice a day. Providing mouth care at least twice a day is essential for maintaining good oral hygiene in residents. Brushing teeth and cleaning the mouth regularly helps prevent dental issues, infections, and bad breath. By doing it twice a day, it ensures that bacteria and plaque are effectively removed, reducing the risk of oral health problems. A: Once a day may not be sufficient to adequately clean the mouth and maintain oral health for residents. C: Only when the resident requests it is not a recommended approach, as residents may not always be aware of their oral care needs. D: Every other day is not frequent enough to prevent oral health issues and maintain good hygiene.

Correct Answer: D

Rationale: The correct answer is D because saying positive things about the food being served helps create a positive dining experience for the residents, leading to improved appetite and enjoyment of the meal. By providing positive feedback, it encourages residents to try new foods and promotes a healthy eating environment. This approach also respects individual preferences and promotes dignity. A: Serving the residents who need the most help with eating first - While important for efficient meal service, it may not be the best approach for promoting a positive dining experience for all residents. B: Doing as much as possible for residents to make mealtimes more efficient - Efficiency is crucial, but it shouldn't compromise the quality of the dining experience or individual preferences. C: Discouraging conversation during meals - Conversation can enhance the dining experience, promote social interaction, and improve overall well-being.

Correct Answer: D

Rationale: The correct answer is D: Ova and parasites. Stool samples for ova and parasites testing must be delivered immediately to prevent the degradation of the specimens, ensuring accurate results. Ova and parasites can deteriorate quickly in the stool, affecting the validity of the test. Blood (A), constipation (B), and mucus (C) do not require immediate delivery to the lab as they are more stable and can be tested accurately even if the sample is not delivered immediately.

Correct Answer: D

Rationale: The correct answer is D: Vaginal walls become drier and thinner. This is a normal age-related change in the female reproductive system due to decreasing levels of estrogen during menopause. Estrogen helps maintain the thickness and moisture of vaginal walls. As estrogen levels decline with age, the vaginal walls can become drier and thinner, leading to symptoms like vaginal dryness and increased risk of infection. A, B, and C are incorrect: A: Lung capability increasing is not a normal age-related change for the female reproductive system. It is more related to factors like physical fitness and environmental exposures. B: Decreased response to vaccines is not a direct age-related change in the female reproductive system. It is influenced by factors like immune function and overall health. C: The amount of calcium in the body increasing is not a normal age-related change for the female reproductive system. It is more related to bone health and hormonal regulation.

Correct Answer: B

Rationale: The correct answer is B: Aorta. The left ventricle pumps oxygen-rich blood into the aorta, which is the main artery that carries blood away from the heart to the rest of the body. This is a crucial step in the systemic circulation of the circulatory system. The aorta then branches out into smaller arteries, leading to the capillaries where gas exchange occurs. Explanation for Incorrect Choices: 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, but blood is not pumped directly from the left ventricle to capillaries. D: Veins - Veins carry blood back to the heart, but they do not receive blood directly from the left ventricle.
