Answer to Question 1

ANS: D
Even a minor allergy to penicillin warrants precautions during administration, because a more severe allergic reaction may occur.
Promethazine is not related to penicillin, therefore no precautions are necessary.
A history of bronchitis and asthma would not be prohibiting factors preventing the use penicillin.
A patient who has a known allergy to sulfa-based drugs does not have a cross-sensitivity to penicillin drugs, therefore no precautions are necessary.

Answer to Question 2

ANS: B
Checking the patient's arm band before administration verifies allergies and is the only option, provided it is done before administration of medications.
A full cup of water is not relevant, because many patients take their meds with a sip of water, and this is not a preadministration assessment.
Monitoring the patient for toxicity would be an evaluation rather than a preassessment.
A physical assessment is not necessary unless the patient's status changes, such as an inability to swallow.
