An older adult patient has been diagnosed with COPD. What characteristic of the patient's current health status would preclude the safe and effective use of a metered-dose inhaler (MDI)?
A) The patient has not yet quit smoking.
B) The patient has severe arthritis in her hands.
C) The patient requires both corticosteroids and beta2-agonists.
D) The patient has cataracts.
Ans: B
Feedback:
Safe and effective MDI use requires the patient to be able to manipulate the device independently, which may be difficult if the patient has arthritis. Smoking does not preclude MDI use. A modest loss of vision does not preclude the use of an MDI and a patient can safely use more than one MDI.
