A nurse is preparing to administer buspirone 7.5 mg PO every 12 hr to a client. The amount available is buspirone 15 mg/tablet. How many tablets should the nurse administer per dose?

(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Tardive dyskinesia (TD) is a potential adverse effect associated with long-term use of antipsychotic medications like haloperidol. It manifests as involuntary, repetitive movements, primarily involving the face, mouth, and tongue. The nurse should suspect tardive dyskinesia when observing the following manifestations:

A. Involuntary pelvic rocking and hip thrusting movements: These movements are characteristic of tardive dyskinesia and indicate abnormal involuntary motor activity.

B. Urinary retention and constipation: These are not typical manifestations of tardive dyskinesia. Urinary retention and constipation can be side effects of anticholinergic medications but are not associated with tardive dyskinesia.

C. Fine hand tremors and pill rolling: These manifestations are more characteristic of parkinsonism, which can be a side effect of antipsychotic medications but is distinct from tardive dyskinesia.

D. Tongue thrusting and lip smacking: These are classic manifestations of tardive dyskinesia and indicate abnormal involuntary movements of the tongue and lips.

E. Facial grimacing and eye blinking: These are also common manifestations of tardive dyskinesia, involving involuntary movements of the face, including grimacing and blinking of the eyes.

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.
