A nurse is assessing a client who is experiencing acute cocaine toxicity. Which of the following findings should the nurse expect?

Heroin is an opioid drug that depresses the central nervous system, which can lead to respiratory depression. This means that heroin can slow down a person's breathing rate, potentially leading to shallow breathing or even stopping of breathing altogether. This is a life-threatening complication and one of the most significant dangers of heroin use.

The other options listed are associated with other substances or conditions:

A- Nasal septum perforation is commonly associated with the use of cocaine, not heroin.

C- Acute pancreatitis is not a commonly reported complication of heroin use.

D- Permanent short-term memory loss is not a specific complication of heroin use, though chronic substance abuse can lead to cognitive impairments and memory problems in general.

Tremors: This choice is correct. Tremors or muscle twitching can be expected in a client experiencing acute cocaine toxicity. Cocaine is a central nervous system stimulant that can cause overstimulation of muscles, resulting in tremors.

Incorrect:

A- Hypothermia: This choice is incorrect. Acute cocaine toxicity is associated with an increase in body temperature (hyperthermia) rather than a decrease (hypothermia). Cocaine is a stimulant that can cause the body to overheat, leading to hyperthermia, which is a dangerous condition that requires immediate medical attention.

B- Hypotension: This choice is incorrect. Cocaine is a stimulant that increases blood pressure and heart rate, leading to hypertension (high blood pressure), not hypotension (low blood pressure). Hypertension is a common cardiovascular effect of cocaine use.

D- Respiratory depression: This choice is incorrect. Respiratory depression, which is a slowing of the respiratory rate and depth, is more commonly associated with depressant drugs like opioids or benzodiazepines. As a stimulant, cocaine tends to have the opposite effect, leading to increased respiratory rate (tachypnea) and sometimes hyperventilation.
