A nurse in an emergency department is assessing a client who has been taking haloperidol for 3 months. The client has a temperature of 39.5* C (103.4° F), blood pressure of 150/110 mm Hg, and muscle rigidity. Which of the following complications should the nurse suspect?
Akathisia
Neuroleptic malignant syndrome
Tardive dyskinesia
Agranulocytosis
The Correct Answer is B
A. Akathisia: Akathisia is characterized by restlessness and an inability to sit still. While it can be a side effect of antipsychotic medications like haloperidol, it does not present with fever, hypertension, and muscle rigidity, as described in the scenario.
B. Neuroleptic malignant syndrome (NMS): NMS is a potentially life-threatening condition associated with antipsychotic medications like haloperidol. It is characterized by hyperthermia, autonomic dysfunction (e.g., hypertension), altered mental status, and severe muscle rigidity. The client's symptoms of fever, elevated blood pressure, and muscle rigidity are consistent with NMS.
C. Tardive dyskinesia: Tardive dyskinesia is a movement disorder characterized by involuntary, repetitive movements of the face, tongue, and other body parts. It is a long-term side effect of antipsychotic medications and typically develops after prolonged use, unlike the acute onset seen in the scenario.
D. Agranulocytosis: Agranulocytosis is a rare but serious side effect of antipsychotic medications, characterized by a severe reduction in white blood cell count, leading to an increased risk of infection. The symptoms described in the scenario are not consistent with agranulocytosis.

Correct Answer is ["2"]
Explanation
To calculate the volume of chlorpromazine to administer per dose, we'll use the formula:
Volume(mL)=Totaldoseneeded(mg)/Concentrationofthemedication(mg/mL)
Given: Total dose needed per dose = 50 mg
Concentration of chlorpromazine injection = 25 mg/mL
Substituting the given values into the formula:
Volume(mL)=50 mg/25 mg/mL
Volume(mL)=2 mL
Rounded to the nearest whole number, the nurse should administer 2 mL of chlorpromazine per dose.
Correct Answer is ["0.25"]
Explanation
To calculate the volume of haloperidol solution needed, we can use the formula:
Volume(mL)=Dose(mg)/Concentration(mg/mL)
Given: Dose of haloperidol = 5 mg
Concentration of haloperidol solution = 20 mg/mL
Substituting the given values into the formula:
Volume(mL)=5 mg/20 mg/mL
Volume(mL)=5/20
Volume(mL)=0.25 mL
Rounded to the nearest hundredth, the nurse should administer 0.25 mL of haloperidol solution.
