A nurse is providing teaching to a guardian of a child who has ADHD.
Which of the following strategies should the nurse suggest to improve the child's ability to concentrate?

Choice A rationale

A dosimeter is used to measure the amount of radiation exposure for the healthcare professional, not the client. It is a personal radiation-monitoring device that provides a record of an individual's accumulated dose of ionizing radiation. Attaching a dosimeter to the client's gown is an inappropriate intervention as the client is the source of the radiation, and the dosimeter is designed to protect the healthcare worker by monitoring their exposure.

Choice B rationale

Brachytherapy involves placing a radioactive source close to the tumor. To minimize the radiation exposure of others, a safe distance is maintained. A distance of at least 1 meter (3.3 feet) from the source of radiation is a standard safety measure for visitors and healthcare staff. This inverse square law principle of radiation safety dictates that intensity decreases with the square of the distance from the source, so increasing distance significantly reduces exposure.

Choice C rationale

When a client is undergoing brachytherapy, it is essential to limit the amount of time visitors spend in close proximity. The typical time limit for visitors is 30 minutes per day, not 2 hours. This is a crucial radiation safety measure that adheres to the principle of "Time, Distance, and Shielding.”. Limiting the time of exposure directly reduces the total radiation dose received by the visitor, thereby minimizing potential harm from the radiation source.

Choice D rationale

For a client undergoing brachytherapy, there is a risk that the radioactive implant could be dislodged and expelled from the body. Therefore, straining the client's urine is a critical intervention. This allows the nurse to inspect for and retrieve the implant if it has been inadvertently expelled, ensuring it is not lost and that appropriate safety protocols for handling radioactive materials are followed. This also prevents potential radiation exposure to others. *.

Choice A rationale

The first step in inserting an indwelling urinary catheter, after gathering supplies and preparing the client, is to lubricate the tip. The application of a generous amount of water-soluble gel to the catheter tip reduces friction as it passes through the urethra. This is crucial for minimizing trauma to the urethral mucosa and decreasing client discomfort during insertion.

Choice B rationale

Positioning the sterile drape is a later step in the procedure, after the catheter has been prepared for insertion. The drape is used to create a sterile field and isolate the perineum. This helps prevent contamination of the sterile catheter and gloves from surrounding non-sterile areas, which is essential for maintaining sterility and preventing infection.

Choice C rationale

Cleansing the meatus with an antiseptic solution is a critical step, but it is performed after the catheter is lubricated and the sterile field is established. This action mechanically and chemically removes microorganisms from the perineal area, reducing the risk of introducing bacteria into the urinary tract during catheter insertion.

Choice D rationale

Attaching a prefilled syringe to the inflation hub is done after the catheter is fully inserted into the bladder and urine flow is established. This step is necessary to inflate the balloon, which secures the catheter in place and prevents it from being expelled. Doing this prematurely could cause urethral damage. *.
