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.

Answer to Question 2

C
Feedback:

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.
