A nurse is teaching a newly licensed nurse about advance directives. Which of the following statements by the newly licensed nurse indicates an understanding of the teaching?

Choice A reason: Limiting visitors to 2 hours daily is not a standard brachytherapy precaution; time limits depend on radiation exposure, typically 30 minutes per visit. Distance (1 meter) is critical. Incorrect limits risk unnecessary restriction or exposure, compromising safety, essential for managing radiation risks in prostate cancer treatment.

Choice B reason: Dosimeters are worn by staff, not clients, to monitor occupational radiation exposure, not part of client care in brachytherapy. Instructing distance is key. Attaching a dosimeter to the client is irrelevant, risking confusion, and neglecting visitor safety measures, critical for minimizing radiation exposure in treatment settings.

Choice C reason: Instructing visitors to stay 1 meter (3.3 feet) from the client minimizes radiation exposure during low-dose brachytherapy, adhering to ALARA principles. This protects visitors while allowing interaction, critical for safety and psychosocial support, ensuring effective radiation safety management in clients with prostate cancer implants.

Choice D reason: Straining urine is relevant for systemic radiation (e.g., iodine-131), not brachytherapy implants, which are localized. Instructing distance is appropriate. Assuming urine straining is needed risks unnecessary procedures, diverting focus from radiation safety measures, critical for protecting visitors and staff in prostate cancer brachytherapy care.

Choice A reason: Increased urine output is not a therapeutic effect of methylphenidate, a stimulant used for ADHD to improve focus and reduce impulsivity. It does not affect renal function or urine production, making this finding irrelevant to evaluating the medication’s effectiveness in a school-age child.

Choice B reason: Increased appetite is not expected with methylphenidate, which commonly suppresses appetite as a side effect. Effective ADHD treatment improves behavior, not appetite, so this finding does not indicate the medication’s success in managing the child’s ADHD symptoms.

Choice C reason: Decreased abdominal pain is unrelated to methylphenidate’s therapeutic effects, which target ADHD symptoms like impulsivity and inattention. While gastrointestinal side effects may occur, pain reduction is not a primary indicator of efficacy, making this an incorrect measure of effectiveness.

Choice D reason: Decreased impulsiveness is a primary indicator of methylphenidate’s effectiveness, as it stimulates the central nervous system to enhance focus and reduce hyperactive-impulsive behaviors in ADHD. This behavioral improvement aligns with therapeutic goals, making it the correct finding to evaluate progress.
