Osteoporosis is caused by a lack of _______ in the diet.

Correct Answer: B

Rationale: Osteoporosis is primarily caused by a lack of calcium in the diet, as calcium is essential for bone health and strength. Calcium helps in maintaining bone density and preventing bone loss, which are key factors in osteoporosis development. Sodium, iron, and protein do not directly impact bone health in the same way as calcium does. Sodium can actually contribute to bone loss, while iron and protein play different roles in the body unrelated to bone density. Therefore, the correct answer is B (Calcium), as it is the most crucial nutrient for preventing osteoporosis.

Correct Answer: C

Rationale: The correct answer is C: Type 2 diabetes. This is because Type 2 diabetes accounts for the majority of diabetes cases worldwide. It is characterized by insulin resistance and relative insulin deficiency. Prediabetes is a precursor to Type 2 diabetes, not the most common form. Type 1 diabetes is an autoimmune condition where the body attacks insulin-producing cells. Hypoglycemia is a condition characterized by low blood sugar levels, not a form of diabetes. Therefore, Type 2 diabetes is the most common form based on prevalence and disease characteristics.

Correct Answer: D

Rationale: Abduction refers to moving a body part away from the body's midline. The correct answer, D, aligns with this definition. Bending a body part backward (A) is hyperextension, not abduction. Another name for the hip (B) is incorrect as abduction is a movement type, not a body part. Similarly, another name for the leg (C) is irrelevant as it does not define abduction. Therefore, choice D is correct as it accurately describes the movement of abduction.

Correct Answer: D

Rationale: The correct answer is D because performing criminal background checks is a legal requirement to protect residents. This ensures that the aides hired have no criminal history that could pose a risk to the safety and well-being of residents. Choice A is incorrect as it generalizes aides as thieves. Choice B is illogical and not a valid reason for conducting background checks. Choice C is incorrect as it implies a motive unrelated to resident safety. Conducting criminal background checks is essential for compliance with laws and regulations and prioritizes the safety of residents.

Correct Answer: A

Rationale: The correct answer is A because the sandwich generation refers to individuals who are simultaneously caring for their children and aging parents. This is a common scenario where individuals find themselves "sandwiched" between the responsibilities of raising their own children while also providing care for their elderly parents. Option B is incorrect because it pertains to a different role of developing menus for long-term care facilities. Option C is incorrect as it refers to providing care for neighbors and children, which is not specific to the sandwich generation. Option D is incorrect as it involves caring for children and pets, which is not the defining characteristic of the sandwich generation.
