Question 16

Varivax should be administered within a maximum of 30 minutes following reconstitution.

After reconstitution, Varivax must be used promptly, specifically within 30 minutes, to ensure its effectiveness and safety for the patient.

A) 30 minutes

This option is correct as Varivax is specifically indicated to be administered within 30 minutes after reconstitution. Delaying administration beyond this timeframe can compromise the vaccine's efficacy.

B) 48 hours

This option is incorrect. Administering Varivax 48 hours after reconstitution is not recommended, as the vaccine's effectiveness may be significantly reduced beyond the specified timeframe of 30 minutes.

C) 7 days

This option is also incorrect. Varivax should not be administered 7 days after reconstitution, as it is imperative to use the vaccine within 30 minutes to maintain its intended efficacy.

D) 2 weeks

This option is incorrect as well. The 2-week timeframe exceeds the maximum allowable period for administering Varivax after reconstitution, which is strictly limited to 30 minutes.

Conclusion

The requirement to administer Varivax within 30 minutes after reconstitution is crucial to ensure the vaccine's potency and safety. All other options provide timeframes that exceed this limit, thus failing to meet the necessary guidelines for effective vaccination. Therefore, Option A is definitively the correct answer.
