Which of the following statements is true of positioning?

Correct Answer: D

Rationale: The correct answer is D because bedbound residents are at high risk for pressure injuries due to prolonged pressure on their skin. Repositioning every three hours helps redistribute pressure, promoting circulation and preventing skin breakdown. Choice A is incorrect because residents may still need assistance with positioning. Choice B is incorrect as constant pressure can lead to pressure injuries. Choice C is incorrect as checking the skin each time a resident is repositioned may not be necessary for every resident.

Correct Answer: D

Rationale: The correct answer is D: Systolic. Systolic blood pressure is the top number in a blood pressure reading. It represents the pressure in the arteries when the heart beats. Diastolic blood pressure is the bottom number, representing the pressure when the heart is at rest between beats. Choice A (Radial) refers to a pulse point, not a blood pressure component. Choice C (Apical) refers to the location where the heartbeat is best heard, not a blood pressure measurement.

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.
