Correct Answer: A

Rationale: The correct answer is A. Paratopes are actually parts of antibodies that bind to antigens, not the antigens themselves. A is incorrect because antigens do not contain paratopes; rather, they contain epitopes or antigenic determinants that are recognized by antibodies. B, C, and D are true statements about antigens. B is true because antigens react with antibodies. C is true because antigens contain antigenic determinants that antibodies recognize. D is true because antigens can elicit an immune response by stimulating the production of antibodies. Therefore, the correct answer is A because antigens do not contain paratopes.

Correct Answer: C

Rationale: The correct answer is C, IgE. IgE is the least abundant immunoglobulin in the normal adult because it is primarily involved in allergic responses and parasitic infections, leading to its lower baseline levels compared to other classes. IgG is the most abundant and provides long-term immunity. IgA is found in mucosal areas and secretions, crucial for local immunity. IgD functions primarily as a B cell receptor and its levels are relatively low in circulation. Therefore, IgE stands out as the least abundant in the normal adult due to its specialized role in immune responses.

Correct Answer: C

Rationale: The correct answer is C: Median nerve. Carpal tunnel syndrome occurs when the median nerve is compressed within the carpal tunnel in the wrist. This compression leads to symptoms like numbness, tingling, and weakness in the hand and fingers. The other choices are incorrect because the radial artery (A) and the brachial artery (B) are blood vessels, not nerves. The ulnar nerve (D) runs along a different path in the arm and is not involved in carpal tunnel syndrome.

Correct Answer: C

Rationale: The correct answer is C: "Skip this week and pick up the schedule next week." Bisphosphonates like alendronate should be taken as directed, typically once weekly. It is important to maintain consistency in dosing to maximize effectiveness and minimize potential side effects. Taking a double dose or taking it late can increase the risk of side effects like gastrointestinal irritation or esophageal damage. Skipping a dose and resuming the schedule next week helps maintain the proper dosing interval. Options A and D suggest taking extra doses, which can be harmful. Option B of taking two doses 3 days apart is also incorrect as it deviates from the prescribed weekly schedule.
