A client has a past medical history of coronary artery disease and emphysema.
The nurse knows which agent is safest to give?
Oxygen at 6 liters per minute via nasal cannula.
Ipratropium via metered dose inhaler.
Propranolol by oral administration.
An organic herbal supplement.
The Correct Answer is B
Choice A rationale
Administering oxygen at 6 liters per minute via nasal cannula risks hypercapnia in a client with emphysema due to impaired CO2 elimination. Oxygen should be titrated to maintain safe saturation levels, usually 88–92%.
Choice B rationale
Ipratropium is a bronchodilator that safely alleviates airway constriction in emphysema without systemic cardiovascular effects, making it suitable for a client with coronary artery disease and chronic obstructive pulmonary conditions.
Choice C rationale
Propranolol is contraindicated in emphysema due to its beta-blocking effects, which may exacerbate bronchoconstriction and reduce respiratory function, posing a significant risk to the client’s health.
Choice D rationale
Organic herbal supplements lack evidence-based safety and efficacy, especially in complex medical conditions like coronary artery disease and emphysema. They can also interact adversely with prescribed medications.
