A nurse is preparing to administer clonazepam 5 mg PO in 3 equally divided doses every 8 hr for a client who has seizures. The amount available is clonazepam 0.5 mg tablets. How many tablets 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.)

Question 5 of 5
A client is to receive enoxaparin 30 mg subcutaneously. Available is enoxaparin 40 mg/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.)
Correct Answer: 0.8
