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 of developing pressure injuries due to prolonged pressure on their skin. Repositioning every three hours helps redistribute pressure and prevent skin breakdown. Choice A is incorrect as residents may require assistance with positioning. Choice B is incorrect as constant pressure can lead to pressure injuries. Choice C is incorrect as checking skin every time a resident is repositioned may not be necessary unless there are specific concerns.

Correct Answer: D

Rationale: The correct answer is D: Systolic. Systolic blood pressure is the top number in a blood pressure reading, representing the pressure in the arteries when the heart beats. Diastolic blood pressure, the bottom number, reflects the pressure in the arteries when the heart is at rest between beats. Radial (A) and Apical (C) are types of pulse points, not blood pressure readings. Therefore, the correct answer is D.

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.
