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

Encouraging the client to ambulate to the bathroom would be inappropriate and potentially harmful. The client is experiencing worsening pain, tingling, and is on a gurney en route to surgery for a fractured radius. Ambulation could exacerbate the injury, increase pain, and risk further complications. Mobility should be restricted until the fracture is stabilized and the client is post-operative.

Choice B rationale

This is the correct action as it assesses for potential complications of compartment syndrome, a critical and urgent condition. The worsening pain and tingling are classic symptoms. Compartment syndrome occurs when pressure builds within the fascial compartments, compromising circulation. A loss of peripheral pulses and delayed capillary refill are late signs of impaired circulation and are key indicators for this limb-threatening emergency.

Choice C rationale

Elevating the arm above the heart would decrease arterial blood flow to the injured extremity, which could worsen tissue perfusion and potentially lead to ischemia. For a client with a suspected circulatory compromise, such as with compartment syndrome, the arm should be kept at the level of the heart to maintain adequate blood flow.

Choice D rationale

Administering a sedative could mask the client's symptoms, particularly the level of pain and changes in mental status, which are crucial indicators of their deteriorating condition. The client's pain is a vital sign that needs to be continuously monitored, and sedation would hinder the nurse's ability to accurately assess for changes in their neurovascular status. .

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. *.
