A nurse is teaching a client who has a new prescription for tetracycline.
Which of the following information should the nurse include in the teaching?

Choice A rationale: A protective environment is typically indicated for immunocompromised clients, such as those with neutropenia or undergoing chemotherapy, not for uncomplicated anemia. The toddler’s white blood cell count is within the normal range of 5,000 to 10,000/mm³, and no evidence of infection risk or severe immunodeficiency is present. Pallor and low hemoglobin are consistent with iron deficiency anemia, which does not require isolation precautions unless additional hematologic compromise is identified.

Choice B rationale: Blood transfusions are reserved for cases of severe anemia with hemodynamic instability, cardiac compromise, or hemoglobin levels below 7 g/dL. This toddler’s hemoglobin is 8.1 g/dL, which while low, does not meet transfusion threshold in a stable, asymptomatic pediatric patient. Transfusion carries risks like iron overload and alloimmunization, making it inappropriate for mild to moderate anemia. Instead, correction through dietary modification and iron supplementation is preferred for age-related iron-deficiency anemia.

Choice C rationale: Iron supplementation is the standard therapy for iron deficiency anemia, especially in toddlers consuming excessive cow’s milk, which lacks iron and can cause occult intestinal blood loss. Hemoglobin of 8.1 g/dL is below the normal pediatric range of 9.5 to 14 g/dL, confirming anemia. Iron replenishment stimulates erythropoiesis by enabling hemoglobin synthesis. Supplementation corrects deficiency over time and should be paired with dietary education to limit milk to <24 oz/day and include iron-rich foods.

Choice D rationale: Continuing antibiotics is unnecessary unless there is ongoing infection. The toddler has recently completed antibiotic therapy for otitis media, and current symptoms do not suggest infection recurrence. Vital signs are stable and the white blood cell count is within normal limits (5,000–10,000/mm³), indicating no acute bacterial process. Antibiotic overuse may disrupt gut flora, impair iron absorption, and contribute to resistant bacterial strains, which is contraindicated in this clinical scenario.

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. *.
