A client has a new prescription for naloxone (Narcan). Which of the following statements indicates the correct therapeutic use of this medication?

This medication is used as a reversal of the effects of opioids.

This medication is used to treat abstinence syndrome.

This medication is used as a pain reliever.

This medication is used to treat hypoglycemia.

Answer and Explanation

The Correct Answer is A

Choice A rationale

Naloxone (Narcan) is an opioid antagonist that works by binding to opioid receptors in the central nervous system, displacing opioids, and reversing their effects such as respiratory depression and sedation.

Choice B rationale

Abstinence syndrome is treated with medications that manage withdrawal symptoms rather than reversing opioid effects, which is not naloxone's primary use.

Choice C rationale

Naloxone does not have analgesic properties, meaning it does not relieve pain; it is specifically used to counteract opioid overdose.

Choice D rationale

Naloxone is not used to treat hypoglycemia, which is a condition of low blood sugar levels, managed by glucose administration.

Choice B rationale

There are specific genes involved in cancer development, as mentioned in the other options.

Choice C rationale

Proto-oncogenes and tumor suppressor genes are both involved, but DNA repair genes also play a significant role.

Choice D rationale

Proto-oncogenes, tumor suppressor genes, and DNA repair genes collectively contribute to cancer development by either promoting or failing to prevent cell proliferation and damage repair.
