Correct Answer: D

Rationale: Scabies is caused by an infestation of the microscopic mite Sarcoptes scabiei. This parasitic mite burrows into the upper layer of the skin, where it lays eggs and causes intense itching and skin irritation. The transmission of scabies usually occurs through close and prolonged skin-to-skin contact with an infested person. Unlike viruses, bacteria, and fungi, which are microorganisms that can also cause skin infections, scabies specifically refers to an infestation by a parasitic mite.

Correct Answer: A

Rationale: Natural killer (NK) cells play a vital role in the innate immune response by identifying and eliminating virus-infected cells, as well as tumor cells, without the need for prior exposure or activation. NK cells are able to detect abnormal cells by recognizing changes in the cell surface molecules, such as downregulation of MHC class I molecules. Once activated, NK cells release cytotoxic granules containing perforin and granzyme, leading to the destruction of the target cell. This direct killing mechanism is crucial for controlling viral infections and preventing the development of tumors. NK cells do not produce antibodies (option
B), present antigens to T cells (option
C), or release cytokines to recruit other immune cells (option
D) as their primary function in the immune response.

Correct Answer: A

Rationale: X-ray is the most appropriate imaging modality for evaluating wrist involvement in rheumatoid arthritis. It can show joint space narrowing, erosions, soft tissue swelling, and periarticular osteopenia. X-rays are readily available, cost-effective, and provide valuable information about joint damage and disease progression in rheumatoid arthritis. In this case, X-ray would be able to confirm the presence of erosions, joint deformities, and assess the severity of the disease in the wrist joint. While MRI and ultrasound can also be helpful in evaluating rheumatoid arthritis, X-ray remains the initial imaging modality of choice due to its convenience and ability to assess bony changes. Dual-energy X-ray absorptiometry (DEX
A) scan is not indicated for evaluating wrist involvement in rheumatoid arthritis.

Correct Answer: D

Rationale: Nurse Merle has to renew her license on or before January 6, 2022, as that date falls at the end of the standard two-year license renewal cycle for nurses in many jurisdictions. Renewing on or before this date will ensure that Nurse Merle maintains her active licensure status and can continue practicing legally without any interruptions. It is important for healthcare professionals like nurses to stay current with their licensure to uphold professional standards and provide quality care to patients.

Correct Answer: D

Rationale: The BEST rationale for the conduct of the program is to deliver safe and quality nursing care to patients on intravenous therapy (IV). This directly ties the purpose of the program to the real-world outcome it seeks to achieve - providing optimal care for patients requiring intravenous therapy. Ensuring safe practice in the hospital (Option
A) is important but it is not specific to the focus of the IV therapy program. Improving nursing practice in general (Option
B) is a noble goal but the program should have a specific and targeted objective. Providing knowledge and skills to all nursing staff in IV Therapy (Option
C) is essential, but the primary aim should be centered on improving patient care outcomes.
Therefore, delivering safe and quality nursing care to patients on IV therapy aligns most closely with the core purpose of the program and should be the primary rationale.
