How often must mouth care be provided for residents?

Correct Answer: B

Rationale: The correct answer is B: At least twice a day. Proper mouth care is crucial for maintaining oral health and preventing complications in residents. Providing mouth care at least twice a day helps in removing bacteria, preventing oral infections, and maintaining overall oral hygiene. It also helps in preventing issues such as plaque buildup, tooth decay, and bad breath. Providing mouth care only once a day may not be sufficient to remove all bacteria and food debris, leading to potential oral health problems. Waiting for the resident to request it (choice C) may result in neglecting necessary oral care. Providing mouth care every other day (choice D) is not frequent enough to maintain optimal oral health for residents in a care facility.

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: Ova and parasites. Stool samples for ova and parasites testing need to be delivered to the lab immediately because these organisms can deteriorate quickly outside the body, affecting the accuracy of the results. Ova and parasites are living organisms that can multiply or die off rapidly, so a timely delivery is crucial. Blood, constipation, and mucus do not require immediate delivery to the lab as they are more stable and do not degrade as quickly as ova and parasites.

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.
