The branch of medicine that deals with the prevention and treatment of obesity is

Correct Answer: B

Rationale: The correct answer is B: Bariatrics. Bariatrics is the branch of medicine that specifically focuses on the prevention and treatment of obesity. This field involves medical and surgical approaches to help individuals manage their weight and improve their overall health. Obstetrics (A) deals with pregnancy and childbirth, not obesity. Pediatrics (C) focuses on the medical care of children. Dietetics (D) is the science of nutrition and the regulation of diet, but it does not specifically address the prevention and treatment of obesity like bariatrics does.

Correct Answer: A

Rationale: Correct Answer: A Rationale: Counting respiration rate directly after pulse helps ensure accuracy as the person's breathing pattern may change quickly. It is convenient to count both while fingers are already placed on the wrist, reducing the need to find the pulse again. This method saves time and effort for the nursing assistant, streamlining the process of vital signs assessment efficiently. Summary of Other Choices: B: This choice assumes that people may consciously alter their breathing rate when observed, which may not necessarily be true in a clinical setting. C: The chest may rise and fall even if the rate is not counted immediately; delaying the count would not affect the chest movements. D: While breathing rates can vary, waiting to take the rate does not guarantee a different result. It is more about ensuring accuracy and efficiency in measurement.

Correct Answer: B

Rationale: The correct answer is B: Serving favorite foods. This is an effective way to prevent unintended weight loss because it increases the likelihood that the resident will enjoy and consume their meals. By serving favorite foods, the resident is more likely to have an appetite and eat enough to maintain their weight. This approach respects the resident's preferences and promotes a positive dining experience. A: Promoting independence by insisting residents feed themselves without help may not be effective if the resident has difficulty feeding themselves, leading to inadequate food intake. C: Telling the resident when a meal looks unappetizing may discourage the resident from eating, resulting in unintended weight loss. D: Insisting that residents eat everything on their trays no matter what can be counterproductive as it may lead to stress or resistance during mealtimes, potentially causing decreased food intake.

Correct Answer: B

Rationale: The correct answer is B: Squatting and leaning forward. This position helps align the rectum for easier elimination by straightening the colon. It mimics a natural squatting position, which relaxes the puborectalis muscle and allows for smoother bowel movements. Lying flat on the bed (A) does not promote proper alignment, lying on the stomach (C) can cause strain, and sitting straight (D) does not facilitate the natural alignment needed for optimal bowel elimination.

Correct Answer: A

Rationale: The correct answer is A because the female reproductive system is responsible for manufacturing ova (eggs), estrogen, and progesterone. Ova are necessary for reproduction, while estrogen and progesterone regulate the menstrual cycle and support pregnancy. Choice B is incorrect because testosterone is a male sex hormone produced by the testes. Choice C is incorrect because sperm is produced by the male reproductive system. Choice D is incorrect because insulin is produced by the pancreas and is involved in regulating blood sugar levels, not a function of the female reproductive system.
