A nurse is reviewing the medical history of a client prior to medication administration and notes a history of an anaphylactic reaction to penicillin. The nurse should identify that which of the following medications is contraindicated for this client?

A. Request that an assistive personnel obtain the medication: Controlled substances like morphine must be handled and administered by a licensed nurse. Delegating this task to assistive personnel violates safe medication administration regulations.

B. Verify the dosage of the medication with the provider: The dosage is typically verified against the provider’s order and the medication administration record rather than contacting the provider each time, unless there is a discrepancy or unusual dose.

C. Record the client's temperature before administering the medication: Morphine administration does not require a temperature check. Assessment should focus on pain level, respiratory rate, blood pressure, and level of consciousness to ensure safe administration.

D. Document obtaining the medication from the locked location: Controlled substances must be securely stored, and accurate documentation of removal from the locked medication location is essential for accountability, legal compliance, and prevention of diversion.

A. "Take the medication with an antacid if you have gastric distress.": Antacids can interfere with the absorption of phenytoin, reducing its effectiveness. It is not recommended to take phenytoin simultaneously with antacids.

B. "Dissolve the capsules in water prior to taking the medication.": Extended-release phenytoin capsules should be swallowed whole to maintain the time-release mechanism. Crushing or dissolving the capsules can cause rapid absorption and increase the risk of toxicity.

C. "Discontinue the medication if you experience a seizure.": Phenytoin should not be stopped abruptly, even if seizures occur, as this can precipitate status epilepticus. Any dosage concerns should be discussed with the healthcare provider before making changes.

D. "Use a soft-bristled toothbrush to brush your teeth.": Phenytoin can cause gingival hyperplasia, leading to swollen and bleeding gums. Using a soft-bristled toothbrush and practicing good oral hygiene helps minimize gum irritation and maintain oral health.
