Final answer:
The answer indicating effective nursing teaching is that Alanna understands the importance of carrying a Medic Alert band, as this reflects awareness of a safety precaution pertinent to her health condition, option b) "I will carry a Medic Alert band at all times."
Step-by-step explanation:
The statement by Alanna that indicates the teaching provided by the nurse has been effective is option b) "I will carry a Medic Alert band at all times." This shows that Alanna has understood the importance of carrying medical identification to alert others of her condition in case of an emergency. This is a critical safety measure for individuals with epilepsy or other medical conditions that might require immediate attention or specific interventions.
Option a) does not reflect a direct understanding of health education, option c) is a personal choice that does not indicate understanding or misunderstanding of the condition, and option d) while important, does not directly relate to the immediate personal actions Alanna should take as part of her health management. Therefore, the correct choice that shows the effectiveness of the nurse's teaching is the commitment to carrying a Medic Alert band.
