A nurse is preparing to administer the first dose of cefazolin via intermittent IV infusion to a client.
Which of the following actions should the nurse take first?

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.

Choice A rationale:

Taking antibiotics when having a virus is not a correct understanding of infection prevention. Antibiotics are ineffective against viruses and should only be used for bacterial infections under the guidance of a healthcare provider. This statement indicates a misunderstanding of infection prevention.

Choice B rationale:

Washing hands for at least 20 seconds with soap and water is the recommended practice for infection prevention. Washing hands for 10 seconds may not be sufficient to remove all germs effectively. This statement does not demonstrate a proper understanding of hand hygiene.

Choice C rationale:

Cleaning a cat's litter box during pregnancy is not recommended due to the risk of contracting toxoplasmosis, a parasitic infection that can harm the fetus. Pregnant individuals should avoid handling cat litter to prevent exposure to this infection. This statement indicates a lack of awareness regarding infection prevention during pregnancy.

Choice D rationale:

Waiting 5 days after the chickenpox sores have crusted before visiting a person with chickenpox demonstrates an understanding of infection prevention. Chickenpox is highly contagious, and individuals should avoid close contact until the sores have fully healed and crusted over. This statement reflects appropriate knowledge about preventing the spread of contagious diseases during pregnancy.
