The nurse is caring for a client that has a diagnosis of alcohol dependence and has come to the Emergency Department with symptoms of alcohol withdrawal. An order is written for lorazepam 3 mg IV. The pharmacy only has the injectable form of lorazepam in a concentration of 2 mg/mL. Each vial contains 1mL. How many vials does the nurse need to retrieve from the med room to prepare the ordered dose? A calculator is activated within your exam. Enter numeric value only. Do not label.
The Correct Answer is ["2"]
To calculate the number of vials needed to prepare the ordered dose of lorazepam 3 mg IV using the injectable form with a concentration of 2 mg/mL, we can use the formula:
Number of vials = Ordered dose divided by concentration per vial
Given:
Ordered dose of lorazepam: 3 mg IV
Concentration of lorazepam in each vial: 2 mg/mL
Plugging in the values:
Number of vials = 3 mg divided by 2 mg/mL
Number of vials = 1.5 vials
Since each vial contains 1 mL, and the ordered dose is 3 mg IV, the nurse will need to retrieve 1.5 mL of lorazepam. This means the nurse will need 2 vials (rounded up from 1.5 vials).

Choice A: Pseudoparkinsonism
Pseudoparkinsonism is a side effect of antipsychotic medications that can manifest with symptoms similar to Parkinson's disease, such as a stooped posture, shuffling gait, and tremors. It is caused by the blockade of dopamine receptors in the basal ganglia of the brain, leading to a disruption in motor control.
Choice B: Blocking the dopamine receptors
Antipsychotic medications, particularly typical antipsychotics (also known as first-generation antipsychotics), work by blocking dopamine receptors in the brain. This action can lead to various side effects, including pseudoparkinsonism, as seen in the client's presentation.
