A client is prescribed Levothyroxine 50 mcg po daily for hypothyroidism. The medication is supplied in 0.1mg tablets. How much should the nurse administer? (Use a leading zero if it applies, round to the tenth place, do not use a trailing zero)

Rationale: Prescribed dose = 50 mcg Available dose = 0.1 mg per tablet Convert 0.1 mg to mcg: 0.1 mg = 100 mcg Set up a proportion: 100 mcg : 1 tablet = 50 mcg : X tablet Cross multiply: 100 × X = 50 × 1 100X = 50 X = 50 ÷ 100 = 0.5 tablet
