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.

No explanation
Correct Answer is B
Explanation
Choice A rationale:
Requesting a provider to evaluate the client in person every 36 hours might be necessary in certain situations but is not directly related to the management of a client in seclusion and restraints. It does not ensure the immediate safety and well-being of the client in this scenario.
Choice B rationale:
Documenting the client's behavior every 15 minutes is essential when a client is in seclusion and restraints. Regular and detailed documentation is crucial to monitor the client's response to the intervention, ensuring their safety, and providing necessary information for the healthcare team.
Choice C rationale:
Ensuring that the prescription for restraints be renewed every 6 hours is important to prevent unnecessary or prolonged use of restraints, but it doesn't address the immediate need for monitoring the client in seclusion and restraints.
Choice D rationale:
Monitoring the client every 30 minutes while restrained might not provide timely information, especially if the client's condition deteriorates rapidly. More frequent monitoring, such as every 15 minutes, allows for closer observation and quicker response to any changes in the client's status.
