A school nurse is performing scoliosis screenings. The nurse should recognize which of the following clinical manifestations as an indication of scoliosis?

A. Place the blood bag in a biohazard bag before discarding: While proper disposal of blood products is important, the immediate priority after stopping the transfusion is to ensure the patient's safety and document the reaction. The blood bag should be sent for analysis, but this action does not address the immediate next steps for patient care.

B. Administer epinephrine subcutaneously: This is not the first action unless the client is experiencing an anaphylactic reaction, which is not indicated in this scenario. The reaction described is more consistent with a febrile non-hemolytic transfusion reaction.

C. Document the reaction in the medical record: This is the most appropriate action following the cessation of the transfusion. Accurate documentation of the reaction ensures that all healthcare providers are informed of the client’s status and the incident, which is critical for ongoing care and safety.

D. Infuse 500 ml. lactated Ringer's IV: While providing IV fluids may be necessary to maintain venous access or manage symptoms, the immediate action after stopping the transfusion should focus on documenting the reaction and notifying the healthcare provider, as appropriate interventions can then be determined.

A) Educating clients about contraindications to specific immunizations: This task relates more to primary prevention, as it aims to prevent disease by informing clients about vaccine safety and appropriateness.

B) Helping clients understand health screenings covered by their insurance plans: This is also more aligned with primary prevention, as it focuses on the importance of screenings to detect health issues early.

C) Using an electronic messaging system to remind clients when to take medications: This is the correct answer. Tertiary prevention focuses on managing and improving the quality of life for individuals with chronic conditions, such as HIV. Reminding clients to take their medications helps prevent disease progression and complications.

D) Providing clients with information about the benefits of exercise: While exercise is beneficial for health, this task is more associated with promoting general health and wellness, aligning with primary prevention efforts rather than tertiary prevention.
