A nurse is preparing to administer meperidine 35 mg IM to a client every 6 hr PRN for pain.
Available is meperidine injection 75 mg/mL. How many mL 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.)
The Correct Answer is ["0.5"]
Given:
Dose required = 35 mg
Concentration of medication = 75 mg/mL Formula:
Volume (mL) = Dose required (mg) / Concentration of medication (mg/mL) Calculation:
Volume (mL) = 35 mg / 75 mg/mL Result:
Volume (mL) = 0.4666667 mL Rounded to the nearest tenth:
Volume (mL) ≈ 0.5 mL

Correct Answer is D
Explanation
A. Minimize the amount of fluid taken while on this drug: Increasing fluid intake is actually recommended to manage potential constipation, another common side effect of anticholinergic medications.
B. Discontinue the medication if adverse effects occur: Discontinuing medication without consulting a healthcare provider is not advisable. Patients should be educated to report any adverse effects to their healthcare provider for appropriate management.
C. Take the medication on an empty stomach to enhance absorption: Benztropine is typically taken with food to minimize gastrointestinal side effects. Taking it on an empty stomach may increase the risk of nausea or stomach upset.
D. Use artificial saliva, sugarless gum, or hard candy to counteract dry mouth: Anticholinergic medications such as benztropine commonly cause dry mouth as a side effect. Stimulating saliva production with these measures can help alleviate dry mouth symptoms.
Correct Answer is D
Explanation
A. Tachycardia is not typically associated with cholinergic drug effects. Cholinergic stimulation tends to slow down the heart rate rather than increase it.
B. Palpitations may occur with certain cardiac arrhythmias or in response to sympathetic stimulation, but they are not typically associated with cholinergic drug effects.
C. Cholinergic drugs are more likely to cause vasodilation rather than vasoconstriction.
Therefore, vasoconstriction is not a common cardiovascular effect of cholinergic drug therapy.
D. Bradycardia is a common cardiovascular effect of cholinergic drug therapy. Cholinergic stimulation slows down the heart rate by increasing parasympathetic activity, particularly at the
sinoatrial (SA) node. Therefore, bradycardia is the cardiovascular effect that nurses should monitor for when administering cholinergic drugs.
