A nurse is teaching a client who has alcohol use disorder about disulfiram. Which of the following client statements indicates an understanding of the teaching?

Rationale:

• Difficulty walking: Bone injury limits weight-bearing ability and causes alterations in gait. Localized pain and instability can make ambulation difficult. Clients often compensate with limping to avoid pressure on the injured limb. In DVT, A clot in the deep veins causes swelling and discomfort, making ambulation painful. The heaviness and fullness in the limb interfere with normal gait. Clients may develop a limp due to localized tenderness.

• Pain: A fracture typically produces sharp, localized pain that worsens with movement. Tissue disruption and swelling contribute to discomfort. The pain limits limb use and is often immediate after injury. DVT often causes aching or cramping pain in the affected limb, especially with walking. Venous congestion and inflammation contribute to tenderness. Pain increases when the calf is compressed or when standing.

• Limb heaviness: Venous obstruction causes blood pooling, producing a heavy and tight sensation. This finding reflects impaired venous return, especially when swelling is also present. It is common in unilateral DVT. A fracture typically causes sharp, localized pain rather than diffuse heaviness. Heaviness is more strongly associated with venous congestion.

• Fever: Low-grade fever may occur due to inflammatory response around the thrombus. Cytokine release produces systemic symptoms during clot formation. It can accompany swelling, warmth, and redness. A simple fracture does not generally cause systemic fever unless infection develops. Fever is more indicative of inflammatory or infectious conditions.

• Edema: Venous blockage leads to unilateral swelling due to trapped fluid and elevated venous pressure. The affected limb becomes warm, enlarged, and firm. This is a hallmark finding in deep vein thrombosis. While swelling may occur after a fracture, the client’s presentation shows significant unilateral edema matching venous obstruction.

Rationale for Correct Choices

• opioid intoxication: The client is drowsy, difficult to arouse, and has a respiratory rate of 10/min, all of which are hallmark findings of opioid intoxication. The presence of a needle in the antecubital space and the need for naloxone also strongly support opioid involvement. The prior history also documents opioid misuse and prior treatment with buprenorphine/naloxone, further increasing the likelihood of opioid intoxication in this episode.

• pupil characteristics: Miotic (pinpoint) pupils are a classic indicator of opioid intoxication and help differentiate it from alcohol intoxication, which typically presents with normal or enlarged pupils. The pupil response directly supports the diagnosis when paired with respiratory depression and altered level of consciousness.

Rationale for Incorrect Choices

• Alcohol withdrawal: Alcohol withdrawal presents with agitation, tremors, diaphoresis, tachycardia, hypertension, and occasionally hallucinations. This client is drowsy with decreased respiratory rate and constricted pupils, which are inconsistent with alcohol withdrawal, making this diagnosis unlikely.

• Alcohol intoxication: Alcohol intoxication often presents with slurred speech, ataxia, and altered mental status, but pupils are usually normal in size and not constricted. There is also no evidence of significant alcohol consumption reported, making alcohol intoxication less likely in this scenario.

• Opioid withdrawal: Opioid withdrawal is characterized by mydriasis (dilated pupils), diaphoresis, piloerection, tachycardia, nausea, vomiting, and agitation. The client’s current presentation of drowsiness, miotic pupils, and respiratory depression is opposite of withdrawal symptoms, ruling out opioid withdrawal.

• Amount of alcohol consumed: The client reportedly had only one beer, which is insufficient to cause coma-level depression. Alcohol intoxication severe enough to cause unresponsiveness with respiratory depression would require significantly higher intake.

• Breath sounds: Clear breath sounds do not help distinguish the cause of the altered mental status. Breath sounds are more useful for identifying respiratory complications, not for differentiating intoxication types.

• Current temperature: A normal temperature does not help identify opioid intoxication versus withdrawal. Temperature fluctuations are more common in severe withdrawal states and are not diagnostic enough to determine the underlying cause in this scenario.
