The nurse is instructing a client about the medication sildenafil (Viagra). Which client statement indicates teaching has been effective?
A) "Viagra should be taken with food."
B) "I can take Viagra anywhere from 1 to 6 hours before sex."
C) "I can take only one pill in a 24-hour period."
D) "Grapefruit juice will decrease the effects of Viagra."
Answer: C
Taking only one pill in a 24-hour period is the recommended dosing for sildenafil (Viagra). Grapefruit juice can lead to increased, not decreased, levels of sildenafil. Sildenafil should be taken on an empty stomach, not with food. The optimum time for administration is 1 hour before sex, but it can be taken up to 4 hours before sex.
