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 C
Explanation
A. Elevated heart rate is not a typical sign of opioid toxicity. Opioids usually have a depressant effect on the cardiovascular system, leading to bradycardia.
B. Hypertension is not a typical effect of opioid toxicity. Opioids often cause hypotension due to vasodilation.
C. Pupillary constriction (miosis).
Acute fentanyl toxicity is associated with opioid overdose, and opioids typically cause miosis (constriction of the pupils). Other common symptoms of opioid toxicity include respiratory depression, sedation, and potentially unconsciousness.
D. Tachypnea is not a typical sign of opioid toxicity. Opioids tend to depress the respiratory system, leading to respiratory depression and potentially hypoventilation.
