A nurse on a pediatric unit is caring for a toddler who has poor dietary intake. Which of the following actions should the nurse take first?

A) "Wash the site daily with warm water": The nurse should instruct the client to wash the radiation treatment site gently with warm water and mild soap (without scrubbing or using harsh soaps). This helps to cleanse the skin without irritating it. Keeping the skin clean can help prevent infection and minimize irritation during the course of radiation therapy. It's important not to use hot water or harsh chemicals, as the skin in the treated area can be sensitive.

B) "Wash skin markings off after each treatment": Skin markings are placed on the client's skin by the radiation oncologist to ensure the radiation is targeted precisely. These marks should not be washed off, as they are necessary for the planning and delivery of radiation. Washing off the marks could affect the accuracy of the treatment.

C) "Apply lotion to the site after treatment": While it may seem like a good idea to apply lotion to moisturize the skin, clients undergoing radiation therapy should avoid applying any lotions, creams, or ointments to the radiation site unless specifically prescribed by their healthcare provider. Some lotions or creams may contain chemicals that could irritate the skin further or interfere with the radiation treatment. Only approved products should be used.

D) "Cover the site with a transparent dressing": Covering the radiation treatment site with a transparent dressing is typically not recommended unless the client has an open wound or is instructed to do so by the healthcare provider. The treated skin should be left exposed to air to promote healing unless advised otherwise. Covering the site could trap moisture, leading to skin irritation or infection.

A) Time: The time of administration is an important factor to clarify. The prescription specifies erythromycin 500mg four times per day, but it does not specify the exact times the medication should be administered. The nurse should clarify the specific times to ensure the medication is given at proper intervals, especially considering the potential for drug interactions and the timing of meals, which may impact absorption.

B) Dosage: The dosage of 500mg is specified clearly in the prescription. There is no indication that the dosage is incorrect or needs clarification. Erythromycin 500mg four times per day is a standard dose for certain infections, so no issues are apparent with the dosage itself.

C) Route: The route of administration (oral, intravenous, etc.) is not specified in the question but is typically understood unless otherwise stated. However, in the context of erythromycin, the most common route is oral. Unless there’s uncertainty about the route, it does not need clarification.

D) Medication: The medication is clearly identified as erythromycin, which is a known antibiotic. There is no ambiguity in the medication prescribed, so there is no need for clarification in this regard. The focus should be on confirming the time of administration.
