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.)

Answer and Explanation

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 C

Explanation

A. Bleeding:

Explanation: Bleeding is not a common adverse effect of haloperidol, which is an antipsychotic medication used to treat conditions like schizophrenia. Haloperidol primarily works on the central nervous system and is not known to directly cause bleeding issues.

B. Cataracts:

Explanation: Cataracts are not a common adverse effect of haloperidol either. While long-term use of some antipsychotic medications can lead to metabolic and endocrine disturbances, which might indirectly impact eye health, cataracts are not a direct and immediate concern with haloperidol use.

C. Dysrhythmias:

Explanation: Correct Answer. Haloperidol has the potential to cause cardiac-related adverse effects, including dysrhythmias (irregular heart rhythms). This is a particular concern in individuals who are predisposed to heart conditions or have other risk factors. The medication can prolong the QT interval, which is a measure of the time it takes for the heart's electrical system to recharge between beats. Prolonged QT interval can lead to serious and potentially life-threatening arrhythmias.

D. Pancreatitis:

Explanation: Pancreatitis is not a common adverse effect of haloperidol. Pancreatitis typically involves inflammation of the pancreas and can be caused by various factors such as gallstones, alcohol consumption, and certain medications. Haloperidol is not known to directly cause inflammation of the pancreas.

A. He will monitor your lithium levels closely while you are taking this medication." B. This medication is addictive, so you will need to discontinue it in six months." C. "Weight gain should be reported to your provider as an indication of lithium toxicity." D. "Your provider may prescribe a diuretic if you have trouble urinating while taking lithium."

Correct Answer is A

Explanation

Lithium is a commonly used medication for treating bipolar disorder, and therapeutic drug monitoring is crucial to ensure its effectiveness and prevent potential toxicity. Monitoring the client's lithium levels in the blood is important because lithium has a narrow therapeutic range, meaning that levels that are too low might not provide the desired therapeutic effect, while levels that are too high can lead to toxicity.

B) "This medication is addictive, so you will need to discontinue it in six months."

Lithium is not considered addictive. It's important to provide accurate information about the nature of the medication to avoid unnecessary concerns.

C) "Weight gain should be reported to your provider as an indication of lithium toxicity."

While weight gain can be a side effect of some medications, it's not a specific indicator of lithium toxicity. Lithium toxicity is characterized by a range of symptoms including tremors, confusion, nausea, vomiting, and excessive thirst, among others.

D) "Your provider may prescribe a diuretic if you have trouble urinating while taking lithium."

Diuretics are generally not recommended with lithium because they can increase the risk of lithium toxicity. Lithium can affect kidney function, and using diuretics may exacerbate this effect. The client should be advised not to use diuretics without consulting their healthcare provider.
