An infant is diagnosed with bronchiolitis. The nurse is teaching the parent how to use a bulb suction to clear the infant's airway. What is the best way for the nurse to evaluate the effectiveness of the teaching?

Choice A reason: Guiding the parent step by step is an effective teaching method, especially during the initial instruction phase. However, it evaluates the nurse’s ability to teach rather than the parent’s ability to perform the skill independently. It does not assess retention or execution without prompting. Choice B reason: Having the parent verbalize each step demonstrates cognitive understanding but does not confirm psychomotor skill. While it shows that the parent knows what to do, it does not ensure they can perform the task correctly or safely. Choice C reason: Providing written instructions supports learning and reinforces teaching, but it is a passive method. It does not allow the nurse to assess whether the parent can apply the information in practice. It is a supplement, not an evaluation tool. Choice D reason: Observing the parent perform the suctioning procedure is the most effective way to evaluate teaching. It allows the nurse to assess both understanding and skill execution, identify errors, and provide immediate feedback. This method ensures the parent can safely and correctly perform the task at home, which is critical for managing bronchiolitis.
