A nurse is caring for a client who has ulcerative colitis and is receiving sulfasalazine. Which of the following findings requires immediate intervention?

A. Increase fluid intake. Clients taking lithium should increase fluid intake to 2-3 litres per day to prevent dehydration and maintain proper lithium excretion. Lithium is excreted by the kidneys, and dehydration can lead to toxic accumulation in the body. Adequate hydration also helps reduce the risk of side effects such as nephrotoxicity and lithium-induced polyuria.

B. Decrease sodium intake. Clients should not decrease sodium intake while on lithium. A low-sodium diet increases lithium reabsorption in the kidneys, leading to a higher risk of lithium toxicity. Instead, sodium intake should remain consistent, and clients should avoid excessive sodium restriction or sudden dietary changes.

C. Eat foods high in potassium. Potassium levels are not significantly affected by lithium therapy. While potassium is essential for overall health, increasing potassium intake is not a specific recommendation for lithium users. Potassium-rich foods are more relevant for clients taking diuretics (e.g., furosemide) or cardiac medications like digoxin.

D. Take the medication 1 hr before meals. Lithium is typically taken with food or milk to minimize gastrointestinal irritation. Taking it on an empty stomach can increase the likelihood of nausea and gastric discomfort, making it harder for clients to adhere to treatment. Clients should follow their provider’s instructions regarding meal timing.

A. Baker's yeast. The hepatitis B vaccine is contraindicated in individuals with a severe allergy to baker’s yeast. This is because the vaccine is produced using Saccharomyces cerevisiae (baker’s yeast), which can trigger an allergic reaction in susceptible individuals. Symptoms of a yeast allergy may include rash, difficulty breathing, and anaphylaxis, requiring the vaccine to be withheld and an alternative plan considered.

B. Nuts. Nut allergies are not related to the hepatitis B vaccine, as it does not contain nut-derived ingredients. While nut allergies can be severe and cause anaphylaxis, they do not pose a specific risk in the administration of this vaccine. Therefore, the presence of a nut allergy alone does not require withholding the immunization.

C. Wheat. A wheat allergy is not a contraindication for the hepatitis B vaccine. Wheat allergies primarily cause reactions to gluten-containing foods or products but do not have any connection to the components used in the production of the vaccine. The vaccine can be safely administered to individuals with wheat allergies.

D. Egg yolk. While some vaccines, such as the influenza vaccine, may be derived from egg proteins, the hepatitis B vaccine is not produced using egg-based components. An allergy to egg yolk does not pose a risk for adverse reactions to this vaccine, so it should not be withheld in individuals with an egg allergy.
