Answer to Question 1

A
Feedback:
Dantrolene is contraindicated in the presence of any known allergy to the drug. It is also contraindicated in the following conditions: spasticity that contributes to locomotion, upright position, or increased function, which would be lost if that spasticity was blocked; active hepatic disease, which might interfere with metabolism of the drug and because of known liver toxicity; and lactation because the drug may cross into breast milk and cause adverse effects in the infant. The other options would not contraindicate the medication.

Filling in the information from the problem: 50 mg/1 mL = 30 mg/X mL. Cross-multiply yielding 0.6 mL required to administer a 30-mg dosage.
