Final answer :
Cardiac surgery patients do not need antibiotics prior to cataract surgery. Procedures such as endoscopy, colonoscopy, and dental cleaning may require antibiotics for these patients. The correct answer is options 4
Step-by-step explanation:
The question at hand is whether cardiac surgery patients require antibiotics prior to certain non-cardiac procedures. Prophylactic antibiotics are important for reducing the risk of hospital-acquired infections (HAI), which includes infections that can occur post-surgery. Taking antibiotics before surgery has been shown to reduce the risk of HAI significantly.
Cardiac surgery patients do not need antibiotics prior to cataract surgery. However, they may require antibiotics before endoscopy, colonoscopy, and dental cleaning. These procedures are considered non-cardiac and do not pose a significant risk of infection to cardiac surgery patients. So, The correct answer is options 4
