A nurse is caring for a client with a new prescription for codeine.
Which of the following is an indication for this medication?
This medication is used for chronic nonproductive cough to decrease the frequency and intensity.
This medication is used to treat allergic rhinitis only.
This medication is used to treat non-allergic rhinitis only.
None of the above.
The Correct Answer is A
Choice A rationale
Codeine is an opioid used for the treatment of chronic nonproductive cough by decreasing the frequency and intensity. It acts on the brain to reduce the urge to cough, providing symptomatic relief for chronic, dry cough.
Choice B rationale
Codeine is not specifically used to treat allergic rhinitis. Medications such as antihistamines and corticosteroids are more commonly used for this condition.
Choice C rationale
Codeine is not used for non-allergic rhinitis. It is primarily an antitussive agent used to manage chronic cough, not for nasal conditions.
Choice D rationale
This choice is incorrect as codeine has specific indications, including the treatment of chronic nonproductive cough, pain relief, and sometimes as an antidiarrheal.

Correct Answer is A
Explanation
Choice A rationale
Metastasis is when cancerous cells spread into or invade nearby tissues and can travel to distant places in the body to form new tumors. This process involves the detachment of cancer cells from the primary tumor, their movement through the bloodstream or lymphatic system, and the establishment of new tumors in other parts of the body.
Choice B rationale
Metastasis specifically involves cancerous cells, not normal cells. Normal cells do not spread and invade other tissues in a way that causes new tumor formation.
Choice C rationale
Metastasis refers to the spread of cancerous cells, not normal cells. Normal cells do not exhibit the same invasive and migratory behaviors as cancerous cells.
Choice D rationale
Metastasis involves the spread of cancerous cells, which can lead to the formation of malignant tumors in distant parts of the body. It does not treat tumors but rather contributes to the progression of cancer.
