A nurse is teaching a group of newly licensed nurses about caring for a client who has a Clostridium difficile infection. Which of the following Instructions should the nurse include in the teaching?

Rationale for correct choices:

• Opioid intoxication: The client exhibits classic signs of opioid overdose, including shallow respirations, bradypnea, bradycardia, hypotension, hypothermia, slurred speech, and constricted pupils. These findings, combined with a history of oxycodone use, indicate opioid intoxication requiring immediate intervention.
• Obtain a prescription for naloxone: Naloxone is an opioid antagonist that reverses the respiratory depression, sedation, and other life-threatening effects of opioid overdose. Timely administration can prevent respiratory failure and death.
• Prepare to initiate mechanical ventilation: The client’s respiratory rate is critically low (10/min) with oxygen saturation at 90%, indicating inadequate ventilation. Mechanical ventilation may be required to maintain oxygenation and prevent hypoxia while naloxone takes effect.
• Pupillary reaction: Monitoring pupillary constriction or dilation helps assess the client’s response to opioid reversal therapy and can indicate ongoing central nervous system depression or improvement.
• Respiratory rate: Continuous monitoring of respiratory rate is essential because hypoventilation is the most immediate life-threatening effect of opioid intoxication. Changes indicate whether interventions like naloxone or ventilation are effective.

Rationale for incorrect choices:

• Alcohol intoxication: Although the client has a history of alcohol use disorder, the current symptoms of miosis, hypoventilation, and hypotension are more consistent with opioid toxicity rather than acute alcohol intoxication.
• Opioid withdrawal: Withdrawal presents with agitation, tachypnea, hypertension, dilated pupils, diaphoresis, and GI upset. This client’s bradycardia, hypotension, and hypoventilation indicate intoxication, not withdrawal.
• Stimulant intoxication: Stimulant overdose typically presents with hypertension, tachycardia, hyperthermia, and agitation. The client’s hypotension, bradycardia, and CNS depression are inconsistent with stimulant use.
• Anticipate administering clonidine: Clonidine is used for opioid withdrawal management, not acute intoxication. Administering it in this scenario would not address the life-threatening hypoventilation or CNS depression.
• Collect a blood sample for ethanol level: While it may be helpful for history, ethanol testing does not address the immediate life-threatening opioid overdose and is not a priority intervention.
• Obtain prescription for restraints: There is no indication for restraints. The client’s symptoms are due to CNS depression, and restraints would not improve their condition and could worsen injury risk.
• Hyperreflexia: This is a sign of opioid withdrawal or CNS stimulant activity, not opioid intoxication. The client’s deep tendon reflexes are decreased, consistent with CNS depression.
• Cardiac arrhythmias: While arrhythmias can occur, there is no evidence in this assessment of dysrhythmias. Monitoring vital signs and oxygenation is more immediately critical.

A. Atrial fibrillation: This dysrhythmia is characterized by an irregularly irregular rhythm with absent or unidentifiable P waves, not a prolonged constant P-R interval.

B. Premature atrial complexes: PACs involve early P waves that may have a normal or slightly different P-R interval, but they do not cause a consistently prolonged P-R interval across all beats.

C. First-degree atrioventricular block: A constant P-R interval greater than 0.20 seconds indicates a first-degree AV block. The atrial impulses are delayed at the AV node, but all impulses are conducted to the ventricles, producing a regular rhythm with prolonged P-R intervals.

D. Complete heart block: In complete heart block (third-degree AV block), there is no relationship between P waves and QRS complexes. The P-R interval is variable, unlike the constant prolongation seen in first-degree AV block.
