A nurse is preparing to administer benztropine 2 mg IM every 12 hr to a client who is experiencing an extrapyramidal reaction. Available is benztropine 1 mg/mL for injection. How many ml should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2"]
The nurse is preparing to administer benztropine 2 mg IM every 12 hours. The concentration of the available benztropine is 1 mg/mL.
To calculate the volume (mL) of the medication needed for the prescribed dose, you can use the formula:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
Plugging in the values:
Volume (mL) = 2 mg / 1 mg/mL = 2 mL
So, the nurse should administer 2 mL of benztropine 1 mg/mL for each dose. Since we're looking for a whole number, we round to the nearest whole number, which is 2 mL.

Correct Answer is ["0.75"]
Explanation
To calculate the volume (ml) of haloperidol decanoate needed for a dose of 75 mg, you can use the following formula:
Volume (ml) = Dose (mg) / Concentration (mg/ml)
Given:
Dose = 75 mg
Concentration = 100 mg/ml
Plugging in the values:
Volume (ml) = 75 mg / 100 mg/ml
Volume (ml) = 0.75 ml
Rounding to the nearest hundredth:
Volume (ml) = 0.75 ml
So, the nurse should administer 0.75 ml of haloperidol decanoate for the dose of 75 mg.
Correct Answer is ["B","D","E"]
Explanation
A. Nystagmus: Nystagmus is not a typical manifestation of alcohol withdrawal. It is more commonly associated with intoxication or neurological conditions. Therefore, it is not included in the effects of alcohol withdrawal.
B. Illusions: Illusions (misinterpretations of external stimuli) are common during alcohol withdrawal, especially in severe cases such as withdrawal delirium (delirium tremens). Clients may misinterpret shadows or objects as threatening.
C. Polyphagia: Polyphagia (excessive eating) is not a recognized manifestation of alcohol withdrawal. Clients with withdrawal may experience nausea or a lack of appetite rather than an increased appetite.
D. Tremors: Tremors, often called "the shakes," are one of the most common early signs of alcohol withdrawal. They usually begin within hours after alcohol cessation.
E. Seizures: Seizures, specifically generalized tonic-clonic seizures, are a serious complication of alcohol withdrawal. They can occur within 6–48 hours after the last drink and are part of alcohol withdrawal syndrome.
