A nurse is preparing to minister amoxicillin 350 mg PO. Available is amoxicillin 250 mg/5 mL. How many mL should the nurse administer? (Round to the nearest whole number.)
The Correct Answer is ["7"]
To calculate the volume (mL) of amoxicillin needed, you can use the following formula:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
Given that the dose is 350 mg and the concentration is 250 mg/5 mL:
Volume (mL) = 350 mg / 250 mg/5 mL
First, calculate the concentration of amoxicillin in mg/mL:
250 mg / 5 mL = 50 mg/mL
Now, use the calculated concentration to find the volume:
Volume (mL) = 350 mg / 50 mg/mL = 7 mL
So, the nurse should administer 7 mL of amoxicillin.

Fine hand tremors and pill rolling are not indicative of tardive dyskinesia. These symptoms are more commonly associated with other neurological or movement disorders.
B. Urinary retention and constipation:
Urinary retention and constipation are not symptoms of tardive dyskinesia. These symptoms are more related to anticholinergic effects of certain medications.
C. Facial grimacing and eye blinking:
Facial grimacing and repetitive, involuntary movements such as eye blinking are characteristic of tardive dyskinesia. These abnormal movements of the face and eyes are commonly seen in individuals who have been on long-term antipsychotic medications, especially older ones like haloperidol.
D. Involuntary pelvic rocking and hip thrusting movements:
Involuntary pelvic rocking and hip thrusting movements are not typical symptoms of tardive dyskinesia. These types of movements are less associated with antipsychotic-induced movement disorders.
E. Tongue thrusting and lip-smacking:
Tongue thrusting and lip-smacking are classic symptoms of tardive dyskinesia. These repetitive, involuntary movements involving the mouth and tongue are often observed in individuals who have been on antipsychotic medications for an extended period of time.
