Answer to Question 1

D
Feedback:
To reduce the possibility of clotting, the lock may be flushed with 2 to 3 mL of saline every 8 hours or as ordered. Heparin is no longer used to flush the lock. When converting to the lock, first, the infusion is stopped and the tube clamped with the slide clamp and the roller clamp to prevent air from entering the line and blood from escaping. Then the nurse removes the primary IV tubing from the extension device, unclamps the extension tube and flushes with the prescribed solution, reclamps the extension tube and removes the syringe. Finally, the nurse inserts the lock cap device firmly into the extension tubing and tapes it firmly in place.

Answer to Question 2

D
Feedback:
The nurse should monitor the client for weight loss when caring for a client suspected to have exophthalmia and goiter. The client will be hyperactive rather than inactive and lethargic. The eyes will bulge, instead of becoming shrunken. The pulse rate will be rapid rather than slow.
