The nurse is preparing to administer regular insulin by continuous IV infusion to a client with diabetic ketoacidosis. The nurse should:
- A. Mix the insulin with Dextrose 5% in water.
- B. Flush the IV tubing with the insulin solution and discard the first 50 mL.
- C. Give the insulin without diluting.
- D. Add the insulin to a solution of normal saline.
Correct Answer: D
Rationale: Regular insulin for IV infusion should be diluted in normal saline to ensure compatibility and prevent adsorption to IV tubing. Dextrose is inappropriate during DKA, and flushing with insulin wastes medication.

MgSO4 is ordered IV following the established protocol for a client with severe PIH. The anticipated effects of this therapy are anticonvulsant and:
- A. Vasoconstrictive
- B. Vasodilative
- C. Hypertensive
- D. Antiemetic
Correct Answer: B
Rationale: An anticonvulsant effect is the goal of drug therapy for PIH. However, we would not want to increase the vasoconstriction that is already present. This would make the symptoms more severe. An anticonvulsant effect and vasodilation are the desired outcomes when administering this drug. An anticonvulsant effect is the goal of drug therapy for PIH; however, hypertensive drugs would increase the blood pressure even more. An anticonvulsant effect is the goal of drug therapy for PIH. MgSO4 is not classified as an antiemetic. Antiemetics are not indicated for PIH treatment.
The client returns to the unit from surgery with a blood pressure of 90/50, pulse 132, respirations 30. Which action by the nurse should receive priority?
- A. Continue to monitor the vital signs
- B. Contact the physician
- C. Ask the client how he feels
- D. Ask the LPN to continue the post-op care
Correct Answer: B
Rationale: Hypotension (BP 90/50), tachycardia (pulse 132), and tachypnea (respirations 30) indicate potential shock or hemorrhage post-surgery, requiring immediate physician notification. Monitoring is secondary, and delegating or asking about feelings delays intervention.
