A client with Parkinson's disease is receiving benztropine (Cogentin) 3.5 mg PO twice daily. The medication is available in 0.5 mg tablets. How many tablets should the nurse administer for each dose? (Enter numeric value only.)
The Correct Answer is ["7"]
To calculate the number of tablets needed, we'll set up a proportion:
x tablets / 3.5 mg = 1 tablet / 0.5 mg
Cross-multiplying:
0.5x = 3.5
Solving for x:
x = 3.5 / 0.5
x = 7
Therefore, the nurse should administer 7 tablets of benztropine for each dose.

Correct Answer is ["1"]
Explanation
To calculate the number of capsules needed, we'll first convert grams to milligrams:
0.1 grams x 1000 mg/gram = 100 mg
Then, we can set up a proportion:
x capsules / 100 mg = 1 capsule / 100 mg
Cross-multiplying:
100x = 100
Solving for x:
x = 100 / 100
x = 1
Therefore, the nurse should administer 1 capsule of Dantrolene.
Correct Answer is ["4.9"]
Explanation
Step 1: Calculate the concentration of dopamine in the IV solution:
400 mg / 250 mL = 1.6 mg/mL
Step 2: Calculate the infusion rate in mL/minute:
12 mL/hour x (1 hour / 60 minutes) = 0.2 mL/minute
Step 3: Calculate the dopamine infusion rate in mg/minute:
0.2 mL/minute x 1.6 mg/mL = 0.32 mg/minute
Step 4: Convert milligrams to micro-grams:
0.32 mg x (1000 mcg / 1 mg) = 320 mcg/minute
Step 5: Calculate the dopamine infusion rate in mcg/kg/minute:
320 mcg/minute / 65 kg ≈ 4.9 mcg/kg/minute
Therefore, the client is receiving approximately 4.9 mcg/kg/minute of dopamine.
