The nurse is reviewing risk factors for cholelithiasis in a client’s history. Which factor most significantly increases the client’s risk for developing gallstones?

Choice A reason: Teaching mask use, hand washing, and distancing is important for preventing COVID-19 spread but is secondary to immediate isolation. Suspected cases require prompt separation to minimize transmission risk, as symptoms like fever and anosmia suggest high infectivity, making isolation the priority action.

Choice B reason: Counseling family to monitor symptoms is a follow-up measure, not the immediate priority. Isolation prevents active transmission in the emergency department, where the client is currently located. Family monitoring is relevant post-discharge but secondary to containing the virus in the acute setting.

Choice C reason: Isolation is the most critical action for a suspected COVID-19 case, as symptoms like fever, anosmia, and aches indicate potential infectivity. Separating the client from others without proper PPE prevents airborne and droplet transmission, protecting patients and staff in the emergency department, making it the priority.

Choice D reason: Reporting COVID-19 results to health authorities is mandatory but occurs after test confirmation. Immediate isolation prevents transmission in the emergency department while awaiting results. Reporting is a secondary administrative action, as the priority is containing the virus in the acute care setting.

Choice A reason: HIV does not primarily cause a deficiency in antibody production. B-cells produce antibodies, but HIV targets CD4 T-cells, impairing their ability to activate B-cells. This indirectly reduces antibody effectiveness, but the primary mechanism is T-cell destruction, not a direct antibody production deficit, making this incorrect.

Choice B reason: HIV infects and destroys helper T-cells (CD4 cells), critical for coordinating immune responses. By reducing CD4 cell counts, HIV impairs activation of B-cells and cytotoxic T-cells, leading to immune suppression. This is the primary mechanism of AIDS-related immune deficiency, making it the correct explanation for HIV pathology.

Choice C reason: Proliferation of suppressor T-cells (regulatory T-cells) is not a primary HIV mechanism. HIV depletes CD4 cells, not suppressor T-cells, which modulate immune responses. While immune dysregulation occurs, the hallmark is CD4 destruction, not suppressor T-cell proliferation, making this an inaccurate description of HIV’s action.

Choice D reason: HIV does not increase B-lymphocyte numbers. It impairs B-cell function indirectly by destroying CD4 cells, which are needed to activate B-cells for antibody production. B-cell hyperactivity may occur in early HIV, but the primary immune suppression results from CD4 cell loss, not B-cell proliferation.
