The nurse prepares a 25-year-old woman for a cesarean section. The patient says she had major surgery several years ago and asks if she will receive a similar 'shot' before surgery. The nurse's response should be based on an understanding that the preoperative medication given before a cesarean section
- A. contains a lower overall dosage of medication than is given before general surgery.
- B. contains reduced amounts of sedatives and hypnotics than are given before general surgery.
- C. contains reduced amounts of narcotics than are given before general surgery.
- D. contains medications similar in type and dosages to those given before general surgery.
Correct Answer: C
Rationale: Preoperative medications for cesarean sections typically include reduced amounts of narcotics to minimize the risk of respiratory depression in the newborn, as narcotics cross the placental barrier. Sedatives and hypnotics are used in similar doses as in general surgery, and the overall dosage is not necessarily lower.

A client in the ICU is given procainamide HCl (Pronestyl) slowly IV push. The nurse should withhold the next dose if which of the following was observed?
- A. Presence of premature ventricular contractions.
- B. Occurrence of severe hypotension.
- C. Recurring paroxysmal atrial tachycardia.
- D. A sedimentation rate of 10.
Correct Answer: B
Rationale: Procainamide treats ventricular and atrial arrhythmias, but severe hypotension is an adverse reaction requiring the dose to be withheld. PVCs (A) and atrial tachycardia (C) are indications for use, and a normal sedimentation rate (D) is irrelevant.
