A nurse is assessing a client who has started taking theophylline. Which of the following client findings should indicate to the nurse that the medication is effective?

A. Monitor the client for hypotension is not specifically required for epoetin alfa administration. Hypotension is not a common adverse effect of this medication.
B. Inject at a 15-degree angle is incorrect. Subcutaneous injections are typically administered at a 45 to 90-degree angle, not 15 degrees.
C. Check the client’s hemoglobin level is essential before administering epoetin alfa. Epoetin alfa stimulates red blood cell production, and monitoring hemoglobin levels helps assess the effectiveness and safety of the treatment.
D. Administer the medication in the deltoid is not the preferred site for subcutaneous injections. Epoetin alfa is usually administered in the abdomen or thigh.

A. Aspirin is not typically used in the treatment of acute cocaine toxicity. Aspirin is an antiplatelet agent used primarily for its effects on blood clotting and is not indicated for managing the symptoms of cocaine toxicity, which include severe agitation, seizures, and cardiovascular complications.
B. Sodium bicarbonate is used in the treatment of certain types of metabolic acidosis and specific drug overdoses, such as tricyclic antidepressants. However, it is not the first-line treatment for acute cocaine toxicity. The primary concerns in cocaine toxicity are neurological and cardiovascular symptoms, which are better managed with other medications.
C. Diazepam is a benzodiazepine that is commonly used to manage the symptoms of acute cocaine toxicity. It helps to control agitation, seizures, and muscle spasms, which are common manifestations of cocaine overdose. Diazepam’s sedative and anticonvulsant properties make it an effective choice in this scenario.
D. Naloxone is an opioid antagonist used to reverse the effects of opioid overdose. Since cocaine is a stimulant and not an opioid, naloxone would not be effective in treating cocaine toxicity. The symptoms and treatment protocols for opioid overdose differ significantly from those for stimulant toxicity.
