A nurse is preparing to administer haloperidol 5 mg IM to a client. Available is haloperidol 50 mg/mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.1"]
To calculate the amount of haloperidol (in mL) that the nurse should administer, use the following formula:
Volume (mL)= Dose (mg)/Concentration (mg/mL)
In this case:
Volume (mL)=5 mg/50 mg/mL
Volume (mL)= 0.1 mL
Therefore, the nurse should administer 0.1 mL of haloperidol.

Correct Answer is A
Explanation
A. Uncontrolled movements around the mouth.
Tardive dyskinesia is a side effect associated with the long-term use of antipsychotic medications, especially first-generation or typical antipsychotics. It is characterized by involuntary, repetitive movements, often involving the face, such as uncontrolled movements around the mouth (e.g., lip smacking, puckering, chewing).
B. Seizures and tremors are not typical adverse effects of tardive dyskinesia. They are more commonly associated with other side effects or conditions.
C. Nausea and vomiting are not typically associated with tardive dyskinesia. These symptoms may be side effects of antipsychotic medications, but they are not characteristic of tardive dyskinesia itself.
D. Hallucinations and delusions are not associated with tardive dyskinesia. Tardive dyskinesia primarily involves involuntary movements and is not related to changes in thought content or perception.
Correct Answer is D
Explanation
A. "You may experience muscle cramping from the induced seizure." While muscle stiffness is possible, the term "muscle cramping" might not accurately describe the postictal state after ECT.
B. "The most common adverse effects of ECT are related to anesthesia." While anesthesia is used during ECT, the most common adverse effects are related to the ECT procedure itself, such as confusion, memory loss, and headache.
C. "You should expect to have ECT once per week for 6 weeks." The frequency and duration of ECT treatments vary based on the individual's response and treatment plan. This statement provides a specific schedule that may not apply to all patients.
D. "You might feel a bit confused and disoriented when you first wake up." This statement accurately reflects a common and expected postictal effect of ECT. Patients undergoing ECT commonly experience confusion and disorientation upon awakening. This is a temporary and expected side effect of the treatment. It's important for the patient to be aware of this possibility as part of the informed consent process.
