A nurse in a provider's office is collecting data from a client.
Which of the following findings should the nurse identify as a risk factor for depression? (Select all that apply.)

Rationales for Each Condition

Opioid Intoxication

1. Sedation: Opioids cause central nervous system depression, leading to drowsiness, confusion, and reduced level of consciousness.
2. Pinpoint Pupils: A hallmark sign of opioid intoxication is miosis (pinpoint pupils) due to parasympathetic nervous system activation.

Stimulant Intoxication (e.g., Methamphetamine)

1. Seizures: Stimulants can lower the seizure threshold, increasing the risk of convulsions.
2. Tachycardia: Stimulants induce sympathetic activation, leading to increased heart rate.
3. Dilated Pupils: Sympathetic nervous system stimulation causes pupil dilation (mydriasis).
4. Paranoia: Stimulant intoxication often results in psychosis, including paranoia and hallucinations.
5. Hypertension: Elevated catecholamines increase blood pressure, seen in stimulant intoxication.

Hallucinogen Intoxication

1. Seizures: Some hallucinogens (e.g., LSD) can induce seizures due to excitatory effects.
2. Tachycardia: Hallucinogens stimulate the autonomic nervous system, increasing heart rate.
3. Dilated Pupils: Similar to stimulants, hallucinogens can cause mydriasis.
4. Paranoia: Hallucinogen intoxication can result in psychosis, including paranoia.
5. Hypertension: Increased autonomic activity leads to elevated blood pressure.

Choice A rationale: Pupils

Dilated pupils are a common sign of stimulant intoxication, particularly with substances like methamphetamine. Given that the client recently injected an unknown substance, pupil dilation could indicate acute intoxication and require urgent evaluation to prevent potential overdose or complications.

Choice B rationale: Heart rate

A heart rate of 121–124/min is significantly elevated, suggesting tachycardia, which can be related to stimulant use (such as methamphetamine) or withdrawal effects. High heart rates, especially in the context of withdrawal, can increase the risk of arrhythmias or cardiac complications, requiring close monitoring and intervention.

Choice C rationale: Orientation

The client was oriented only to person upon admission, which suggests altered mental status. Substance intoxication or withdrawal can impair cognitive function, decision-making, and awareness, increasing the risk for agitation, confusion, or more severe withdrawal symptoms such as hallucinations or seizures.

Choice D rationale: Respiratory rate

A respiratory rate of 20/min falls within the normal range (typically 12–20 breaths per minute) and does not indicate immediate distress requiring escalation of care.

Choice E rationale: Medical history

While knowing the client’s medical history is important for long-term care planning, it does not require immediate reporting unless the client has a history of conditions that could complicate withdrawal.

Choice F rationale: Oxygen saturation

An oxygen saturation of 98% on room air is within normal limits, meaning oxygenation is adequate. There is no immediate concern requiring intervention based on this finding.
