A nurse is providing discharge teaching to a client following a total gastrectomy.
The nurse should instruct the client about which of the following medications?
Vitamin B12.
Ranitidine.
Vitamin K.
Metoclopramide.
The Correct Answer is A
Choice A rationale:
After a total gastrectomy, the client lacks the intrinsic factor necessary for the absorption of vitamin B12 in the terminal ileum. Therefore, vitamin B12 supplementation is essential to prevent pernicious anemia, a condition caused by vitamin B12 deficiency. The absence of intrinsic factor hinders the absorption of vitamin B12 from dietary sources, making it necessary to provide this vitamin through injections or high-dose oral supplements. Vitamin B12 supplementation is a standard practice following a total gastrectomy.
Choice B rationale:
Ranitidine is a histamine-2 (H2) receptor antagonist used to reduce stomach acid production. It is not directly related to vitamin B12 deficiency and is not typically prescribed following a total gastrectomy. Vitamin B12 supplementation, on the other hand, addresses the specific deficiency caused by the absence of intrinsic factor.
Choice C rationale:
Vitamin K is essential for blood clotting and bone health. However, it is not the primary concern following a total gastrectomy. Vitamin B12 deficiency leading to pernicious anemia is the major focus of post-gastrectomy supplementation. While vitamin K may be important for overall health, it is not the immediate priority in this scenario.
Choice D rationale:
Metoclopramide is a medication used to treat gastrointestinal disorders, including gastroparesis and gastroesophageal reflux disease (GERD). It does not directly address the vitamin B12 deficiency resulting from the absence of intrinsic factor. Vitamin B12 supplementation is specifically indicated to prevent pernicious anemia in this context.

Correct Answer is B
Explanation
The correct answer is Choice B.
Choice A rationale: Maintaining bed elevation at 20 degrees is not recommended. The recommended bed elevation for patients receiving enteral tube feedings is at least 30 to 45 degrees.This is to prevent aspiration of the feeding solution into the lungs.
Choice B rationale: Flushing the tubing with 30 mL of water every 4 hours is a recommended practice.This helps to maintain the patency of the feeding tube and prevent clogging.
Choice C rationale: Checking for gastric residual every 12 hours is not sufficient.For patients receiving continuous tube feedings, gastric residual volume (GRV) should be monitored every 4 hours.This helps to assess tolerance to the feeding and prevent complications such as aspiration.
Choice D rationale: Placing enough formula in the container to last 18 hours is not recommended.For an open system, the formula should be replaced every 4 hours to prevent bacterial growth.
