Correct Answer: D

Rationale: The correct answer is D: Increased calcium level. Parathyroid hormone functions to increase blood calcium levels. When calcium levels are low, the parathyroid gland releases PTH to stimulate the release of calcium from bones and increase calcium absorption from the intestines and kidneys. This helps to maintain normal calcium levels in the blood. Choices A, B, and C are incorrect because decreased phosphate level, functioning thyroid gland, and adequate vitamin D level are not direct requirements for the action of parathyroid hormone.

Correct Answer: B

Rationale: The correct answer is B: IgE. IgE is specific to allergic responses as it binds to mast cells and basophils, triggering the release of histamine and other inflammatory mediators. IgA is more involved in mucosal immunity, IgG is involved in long-term immunity and opsonization, and IgM is the primary antibody in the primary immune response. IgB is not a known immunoglobulin. Therefore, IgE is the specific immunoglobulin associated with allergic responses due to its role in mediating hypersensitivity reactions.

Correct Answer: C

Rationale: The correct answer is C: positive wound cultures. Osteomyelitis is an infection of the bone that is typically diagnosed through wound cultures. This assessment helps to identify the causative organism and guide appropriate treatment. Choices A and D are not typical findings in osteomyelitis. Choice A describes symptoms of poor circulation which are not specific to osteomyelitis. Choice B, decreased white blood cell count, is typically not seen in the presence of an infection like osteomyelitis.

Correct Answer: B

Rationale: The correct answer is B, Middle ear. This is because the middle ear is the most common site for ear infections due to its anatomy, including the Eustachian tube that can easily become blocked, leading to fluid buildup and infection. The outer ear (A) is less susceptible to infections, while the inner ear (C) and semicircular canal (D) are not typically involved in ear infections, as they are more related to balance and hearing functions rather than infection susceptibility.
