A nurse is preparing a laboring person for a cesarean birth. What is the most important action before the procedure?
- A. administer preoperative medication
- B. administer preoperative antibiotics
- C. assist with perineal care
- D. apply pressure to the abdomen
Correct Answer: A
Rationale: The correct answer is A: administer preoperative medication. Before a cesarean birth, it is crucial to administer preoperative medication to ensure the person's comfort and safety during the procedure. This medication can include pain relief and sedatives to manage anxiety. Administering antibiotics (choice B) is important to prevent infection, but it typically occurs after preoperative medication. Assisting with perineal care (choice C) and applying pressure to the abdomen (choice D) are not necessary steps before a cesarean birth.
