A client with a history of ECT describes difficulty managing stressful scenarios. What technique should the nurse recommend for long-term stress management?

Choice A reason: Caffeine consumption is a stimulant that increases central nervous system activity. For a client already experiencing agitation and anxiety related to a psychotic disorder, caffeine can exacerbate symptoms, increase heart rate, and potentially worsen paranoia or restlessness, making it counterproductive for stress management in this population.

Choice B reason: High-intensity exercise can sometimes increase physiological arousal and cortisol levels in the short term. While regular exercise is beneficial, an agitated client may find the intensity overwhelming or overstimulating, which could inadvertently increase their level of distress rather than providing the desired calming effect.

Choice C reason: Competitive sports involve high levels of social pressure, physiological arousal, and potential frustration. For a client struggling with psychosis and agitation, the competitive nature and complex social dynamics of sports may trigger further anxiety or disorganized thinking, rather than promoting emotional stability and relaxation.

Choice D reason: Yoga and meditation focus on controlled breathing, mindfulness, and gentle movement. These techniques activate the parasympathetic nervous system, helping to lower heart rate and reduce the "fight or flight" response. This provides a grounding, low-stimulation environment that is highly effective for reducing agitation in psychiatric patients.

To calculate the volume of medication to be administered, the nurse should use the standard dosage formula: (Desired Dose / Have Dose) x Volume = Amount to Administer. In this clinical scenario, the prescribed amount (Desired) is 7.5 mg, and the concentration on hand (Have) is 5 mg per 1 mL.

Calculation:

Formula: (7.5 mg / 5 mg) x 1 mL = X

Step 1: 7.5 divided by 5 equals 1.5.

Step 2: 1.5 multiplied by 1 mL equals 1.5 mL.

The nurse must accurately draw up 1.5 mL of the diazepam solution into the syringe to provide the exact 7.5 mg dose ordered by the physician.

Choice A reason: This is the mathematically correct volume derived from dividing the prescribed 7.5 mg by the concentration of 5 mg/mL. Accurate calculation is vital in intravenous administration to ensure therapeutic efficacy while avoiding the respiratory depression associated with benzodiazepine toxicity.

Choice B reason: A volume of 0.5 mL would only provide 2.5 mg of diazepam (0.5 mL x 5 mg/mL). This is an under-dose of the prescribed 7.5 mg, which would likely fail to produce the necessary pharmacological effect for the patient's condition.

Choice C reason: A volume of 1.0 mL would provide exactly 5 mg of diazepam. This does not meet the provider's order of 7.5 mg, resulting in a sub-therapeutic dose that could compromise the management of acute anxiety or seizure activity.

Choice D reason: A volume of 2.5 mL would provide 12.5 mg of diazepam (2.5 mL x 5 mg/mL). This constitutes a significant medication error and overdose, increasing the risk of severe central nervous system depression, hypotension, and potential respiratory arrest.
