Antibiotics are given preoperatively to orthopedic patients to prevent postoperative infections. Antacids increase the gastric pH and reduce the volume of gastric fluid. Antiemetics enhance gastric emptying. Anticholinergics reduce oral and respiratory secretions to decrease the risk of aspiration and vomiting.
Answer to Question 2
Correct Answer: 1
Older adults are susceptible to renal insufficiency, which puts them at risk for accumulation of metabolic by-products and medications dependent on renal clearance. Medication dosages will need to be adjusted for the older patient with a low glomerular filtration rate. The glomerular filtration rate will not impact the patient's postoperative activity level, amount of intraoperative blooding, or oxygenation status.
