A nurse is collecting data from a client before administering a hepatitis B immunization. The nurse should withhold the immunization if the client is allergic to which of the following substances?

Baker's yeast

Nuts

Wheat

Egg yolk

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is ["1"]

Explanation

Convert pounds to kilograms:

Conversion factor: 1 kg = 2.2 lb

=145 lb / 2.2 lb/kg

= 65.9 kg

Calculate the total daily dose:

Total daily dose (mg) = Weight (kg) × Dosage (mg/kg/day)

= 65.9 kg 3 mg/kg/day

= 197.7 mg/day

Calculate the dose per administration (divided into two doses):

Dose per administration (mg) = Total daily dose (mg) / Number of doses

=197.7 mg/day / 2 doses

= 98.85 mg/dose

Calculate the number of tablets per dose:

Number of tablets = Desired dose (mg) / Available dose (mg/tablet)

=98.85 mg/dose / 100 mg/tablet

= 0.9885 tablets

Round to the nearest whole number:

0.9885 tablets is 1 tablet

A. Rash B. Diarrhea C. Nausea D. Metallic taste in mouth

Correct Answer is A

Explanation

A. Rash. A rash while taking allopurinol can indicate a serious hypersensitivity reaction, including Stevens-Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN). These life-threatening conditions involve widespread skin blistering, mucosal involvement, and systemic symptoms. Immediate discontinuation of allopurinol and medical intervention are required to prevent severe complications.

B. Diarrhea. Mild gastrointestinal disturbances, including diarrhea, are common with allopurinol use. While bothersome, diarrhea is not life-threatening and can often be managed by adjusting the dose or taking the medication with food. It does not require immediate discontinuation unless severe or persistent.

C. Nausea. Nausea is a common, mild side effect of allopurinol that usually resolves with time or by taking the medication after meals. It is not an emergency and does not require urgent intervention unless accompanied by other concerning symptoms such as vomiting or severe abdominal pain.

D. Metallic taste in mouth. A metallic taste can occur with allopurinol use but is not harmful. It is a minor side effect that does not indicate toxicity or severe adverse reactions. Clients can be reassured that this effect is temporary and not a reason to stop the medication.
