The client should be instructed to report signs of colchicine toxicity, such as
nausea, diarrhea, vomiting, and/or abdominal pain, to the health care provider.
Food inhibits the absorption of colchicine when ingested concurrently. Limited
fluid intake decreases the excretion of the uric acid crystals, which contributes to
painful attacks. Typically, a client should remain on a daily dose of colchicine to
decrease the number and severity of acute attacks, so stopping the medication
after the pain resolves is not indicated.

pressure. This client's ingestion of penicillin and presenting clinical picture
indicate the client is having an acute reaction with respiratory difficulty. Options
B, C, and D are other physiologic responses to medications, but immediate action
is required for a potential loss of airway, breathing, and circulation.

elements required for DNA and RNA synthesis and inhibits enzymes necessary for
cellular function and replication?
A. Alkylating agents
B. Antimetabolites
C. Antitumor antibiotics
