A nurse is reinforcing teaching with a client who is about to undergo a thoracentesis. Which of the

following statements by the client indicates an understanding of the information?

Answer: C

Rationale:

A) Apply a topical corticosteroid ointment to the scalp: Corticosteroids are not indicated for the treatment of Pediculosis capitis (head lice). The treatment focuses on eliminating the lice and nits, typically through pediculicide medications like permethrin or ivermectin. Corticosteroids are used to reduce inflammation and itching, but they do not kill the lice or their eggs.

B) Soak hair brushes and combs in soapy water: Soaking hair brushes and combs in soapy water alone is not sufficient to kill lice. Items such as hair brushes should be soaked in hot water (130°F or higher) for at least 5-10 minutes to ensure any lice or nits present are killed. This is a critical step to prevent reinfestation.

C) Wash the bed linens in hot water: Washing bed linens in hot water (130°F or higher) is essential to eliminate lice and nits that may have transferred onto bedding. This prevents the spread and recurrence of lice. Items that cannot be washed should be sealed in a plastic bag for 2 weeks to kill the lice.

D) Clean the child's toys with a 1:10 bleach solution: Lice are spread through direct contact and cannot live on inanimate objects for long periods. Cleaning toys with bleach is unnecessary for lice removal and can be harmful to the toys or the child if not properly rinsed.

The correct answer is Choice C.

Choice A rationale:

• While maintaining a distance of 3 feet can reduce the risk of direct contact transmission, it is not the most effective measure for contact isolation precautions.
• Contact isolation aims to prevent the spread of pathogens that can be transmitted through direct or indirect contact with the infected person or contaminated objects.
• A distance of 3 feet may not be sufficient to prevent transmission via droplets or fomites (inanimate objects that can harbor infectious agents).

Choice B rationale:

• Sterile gloves are not routinely required for contact isolation precautions.
• They are primarily used for sterile procedures or when there is a risk of exposure to blood or body fluids.
• For contact isolation, standard clean gloves are usually sufficient to protect against transmission via direct contact.

Choice C rationale:

• Leaving equipment that is used routinely in the client's room is a crucial part of contact isolation precautions.
• This practice prevents the spread of infection by minimizing the movement of potentially contaminated items outside of the isolation room.
• Equipment like stethoscopes, blood pressure cuffs, and thermometers should be dedicated to the client's use and not shared with other patients.

Choice D rationale:

• Negative-pressure airflow rooms are used for airborne isolation precautions, which are designed to prevent the spread of pathogens that can be transmitted through the air.
• Contact isolation does not specifically require a negative-pressure room, as the primary mode of transmission is through direct or indirect contact, not airborne particles.
