Which patient using an inhaler would benefit most from using a spacer?

Choice A reason: Hearing impairment affects communication, not inhaler technique. Spacers aid coordination, not auditory issues, making them less beneficial for this patient, as proper instruction can address hearing-related challenges. Choice B reason: Dry powder inhalers require strong inhalation, not typically aided by spacers, which are designed for metered-dose inhalers. COPD patients may benefit, but coordination issues are more critical, making this less applicable. Choice C reason: A 25-year-old with limited extremity coordination struggles with synchronizing inhalation and actuation in metered-dose inhalers. Spacers simplify delivery, ensuring effective medication deposition, making this the patient who benefits most. Choice D reason: A repaired cleft palate may affect oral anatomy, but alertness suggests adequate inhalation ability. Spacers are less critical than for coordination issues, making this patient less likely to benefit most.
