A nurse is preparing to administer 7 mg of haloperidol IM to a client who is severely agitated. Haloperidol injection of 5 mg/mL is available. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.4"]
Step 1 is to identify the required dose, which is 7 mg of haloperidol.
Step 2 is to identify the concentration of the available haloperidol injection, which is 5 mg/mL.
Step 3 is to calculate the volume to be administered using the formula: Volume = Dose ÷ Concentration.
So, let's calculate:
Volume = 7 mg (Dose) ÷ 5 mg/mL (Concentration)
This gives us:
Volume = 1.4 mL
However, we need to round the answer to the nearest tenth and use a leading zero if it applies. So, the final volume to be administered is 1.4 mL. The nurse should administer 1.4 mL of haloperidol injection.

Correct Answer is B
Explanation
Choice A reason: Avoiding television when hearing voices is not a recognized strategy for relapse prevention in schizophrenia. While reducing stimuli during episodes of auditory hallucinations can be helpful, it is not a substitute for professional treatment and medication adherence, which are key to relapse prevention.
Choice B reason: Informing a counselor about trouble sleeping is important because sleep disturbances can be an early indicator of a potential relapse. Maintaining open communication with healthcare providers about changes in sleep patterns allows for timely interventions and adjustments in treatment to prevent a relapse.
Choice C reason: Listening to the voices is not advisable as it may reinforce the hallucinations. Instead, clients are encouraged to engage in reality-based activities and to discuss their experiences with their healthcare providers to manage symptoms effectively.
Choice D reason: Isolation can exacerbate symptoms of schizophrenia and increase the risk of relapse. It is important for individuals to maintain social contacts and support systems as part of a comprehensive relapse prevention strategy.
