A nurse is caring for a client who has lung cancer and has a sealed radiation implant. Which of the following actions should the nurse take? (Select all that apply)
Instruct visitors who are pregnant to remain 3 feet from the client.
Wear a lead apron when providing care.
Place the client in a semi-private room.
Close the door to the client’s room.
Limit visitors to 30 minutes per day.
Correct Answer : B,D,E
Choice A reason: Instructing pregnant visitors to stay 3 feet away is insufficient, as radiation from a sealed implant requires greater distance (typically 6 feet) or complete avoidance. Pregnant individuals should not visit to minimize fetal exposure, making this precaution inadequate and incorrect for safety.
Choice B reason: Wearing a lead apron shields the nurse from radiation exposure during close contact with the sealed implant, adhering to ALARA (As Low As Reasonably Achievable) principles. This protects the nurse while providing care, making it a necessary and correct safety measure.
Choice C reason: Placing the client in a semi-private room is unsafe, as radiation from the implant could expose other patients. A private room is required to minimize radiation risk to others, making this action incorrect and against radiation safety protocols.
Choice D reason: Closing the client’s door reduces radiation exposure to others outside the room, as sealed implants emit continuous radiation. This containment measure, combined with signage, ensures safety for staff and visitors, making it a correct and essential action.
Choice E reason: Limiting visitors to 30 minutes per day minimizes cumulative radiation exposure, protecting visitors from the sealed implant’s emissions. Time restrictions are standard in radiation safety protocols, ensuring minimal risk while allowing controlled visits, making this a correct action.

Correct Answer is D
Explanation
Choice A reason: Penicillin, an antibiotic, has no known interactions with saw palmetto, a herbal supplement used for BPH. Saw palmetto affects prostate function, not antibiotic metabolism, so this combination is safe, making it an incorrect choice for an adverse interaction.
Choice B reason: Ipratropium, used for respiratory conditions, does not interact with saw palmetto, which targets prostate health. Their mechanisms are unrelated, and no significant drug-herb interaction exists, making this medication an incorrect choice for an adverse interaction with saw palmetto.
Choice C reason: Zolpidem, a sedative, has no documented interactions with saw palmetto. Saw palmetto’s effects on prostate tissue do not influence zolpidem’s central nervous system actions, so this combination is safe, making it incorrect for an adverse interaction.
Choice D reason: Finasteride, used for BPH, may interact with saw palmetto, as both reduce prostate size via similar mechanisms (inhibiting 5-alpha-reductase). Combined use can amplify effects or cause additive side effects, making this a potential adverse interaction, thus the correct choice.
Correct Answer is D
Explanation
Choice A reason: Varicella, a viral infection, is not treated with antibiotics, which target bacteria. Returning to school after 24 hours of antibiotics is incorrect, as contagiousness persists until lesions crust, typically 5-7 days, risking transmission if the child returns prematurely.
Choice B reason: A negative titer result indicates immunity or resolved infection but is not a practical criterion for school return. Varicella contagiousness depends on lesion crusting, not serology, which is complex and unnecessary when clinical signs confirm reduced infectivity in affected children.
Choice C reason: Fever subsidence does not ensure non-contagiousness in Varicella. The virus spreads via respiratory droplets and lesions until crusted. Allowing return based on fever ignores transmission risk, as active lesions remain infectious, potentially spreading the virus in school settings.
Choice D reason: Varicella is contagious until lesions crust over, typically 5-7 days post-rash. Crusting indicates the end of viral shedding, ensuring safety for school return. This aligns with infection control guidelines, preventing transmission via contact or respiratory routes in communal settings.
