A nurse is preparing to administer phenobarbital 30 mg PO to a client. Available is phenobarbital 20 mg/5 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["7.5"]
To calculate the correct dosage, use the formula:
Dose to administer = (Desired dose/Available dose) ×Volume available
Given:
Desired dose = 30 mg
Available ,dose = 20 mg
Volume available = 5 mL
(30mg/20mg) × 5ml = 7.5ml
Final Answer:
7.5 mL
