Question

you receive a prescription for ocuflox, the instructions read: instill 2 gtts into the right eye q8h for 7 days. calculate how many drops the patient will receive in 7 days? 56 gtts 84 gtts 42 gtts 21 gtts

Explanation:

Step1: Calculate number of administrations per day

The medication is to be instilled every 8 hours (q8h). There are 24 hours in a day. So the number of administrations per day is $\frac{24}{8}=3$.

Step2: Calculate number of drops per day

The patient is to instill 2 drops (gtts) each time. With 3 administrations per day, the number of drops per day is $2\times3 = 6$.

Step3: Calculate number of drops in 7 days

If there are 6 drops per day and the treatment is for 7 days, then the total number of drops in 7 days is $6\times7=42$.

Answer:

42 gtts
