According to the USDA's MyPlate icon which food groups should make up at least half of a person's plate?

Correct Answer: B

Rationale: The correct answer is B: Vegetables and fruits. According to MyPlate, half of a person's plate should be filled with vegetables and fruits to promote a balanced and healthy diet. Vegetables and fruits are rich in essential nutrients like vitamins, minerals, and fiber, which are important for overall health. Choosing these food groups helps to lower the risk of chronic diseases and maintain a healthy weight. Grains and proteins (choice A) are also important but should not make up half of the plate. Dairy and proteins (choice C) do not align with MyPlate recommendations. Grains and fruits (choice D) do not provide a variety of nutrients compared to vegetables and fruits.

Correct Answer: B

Rationale: The correct answer is B: Standing. This position allows for optimal bladder emptying by using gravity to aid in the process. It also promotes good urinary flow and reduces the risk of incomplete emptying. Sitting (A) may not fully empty the bladder, lying (C) can cause difficulty in aiming, and crouching (D) may not provide the best angle for efficient urination. Standing is the most recommended position for men to urinate based on anatomical and physiological considerations.

Correct Answer: B

Rationale: The correct answer is B because scabies is a skin infestation caused by the Sarcoptes scabiei mite, leading to symptoms such as rash, intense itching, and sores that can get infected. Choice A is incorrect as scabies is caused by mites, not bacteria. Choice C is incorrect because scabies is highly contagious through direct skin-to-skin contact. Choice D is incorrect as scabies can affect individuals of all ages, not just teenagers and young adults.

Correct Answer: A

Rationale: The correct answer is A: Iron-deficiency anemia. Iron deficiency is the leading cause of anemia worldwide due to inadequate intake or absorption of iron. This leads to decreased production of red blood cells. Choice B, hypoxia, is a symptom of anemia but not a specific type. Choice C, pernicious anemia, is caused by a lack of intrinsic factor needed for vitamin B12 absorption, not iron. Choice D, pulmonary anemia, is not a recognized form of anemia.

Correct Answer: C

Rationale: The correct answer is C because a full weight-bearing order for a resident with a total hip replacement means that the resident can bear full weight on both legs. This is important for proper rehabilitation and preventing complications. Choice A is incorrect as it indicates partial weight-bearing. Choice B is incorrect as it indicates no weight-bearing, which is not typically recommended post-hip replacement surgery. Choice D is incorrect as abduction is not specifically related to weight-bearing status after a hip replacement. Therefore, the correct answer is C because it accurately reflects the desired weight-bearing status for a resident with a total hip replacement.
