The nurse evaluates the effects of warfarin by monitoring what lab test?

Choice A rationale

Schedule I drugs have no medical use and high abuse potential, unlike morphine.

Choice B rationale

Schedule III drugs have less abuse potential than Schedule II, making this incorrect for morphine.

Choice C rationale

Schedule IV drugs have even lower abuse potential, incorrect for morphine.

Choice D rationale

Schedule II drugs have high abuse potential with medical use, fitting morphine's classification.

Choice A rationale

Administering amoxicillin when a patient has a known allergy to penicillin can result in a serious allergic reaction. It is important to avoid using any beta-lactam antibiotic in patients with a history of penicillin allergy.

Choice B rationale

Contacting the provider to discuss using a different antibiotic is the safest course of action. The provider can prescribe an alternative antibiotic that does not belong to the beta-lactam class, reducing the risk of an allergic reaction.

Choice C rationale

Asking the provider to order an antihistamine does not address the underlying risk of administering a beta-lactam antibiotic to a patient with a penicillin allergy. Antihistamines are used to manage allergic reactions, not to prevent them.

Choice D rationale

Requesting an order for a beta-lactamase resistant drug does not eliminate the risk of an allergic reaction, as these drugs still belong to the beta-lactam class and can trigger the same allergic responses in sensitive individuals.
