Question 1 of 5
The client, who had been prescribed sildenafil 2 weeks ago for erectile dysfunction, calls the clinic to report that nothing happens, despite taking sildenafil orally and waiting for his erection to develop. Which fact should the nurse consider before responding to the client?
Correct Answer: C
Rationale: A. In clinical trials, some improvement in erectile hardness and duration was reported by 70% of men taking sildenafil. B. Sildenafil should be taken orally. C. Sildenafil (Viagra) enhances the normal erectile response to sexual stimuli by promoting relaxation of arterial and trabecular smooth muscle. The resultant arterial dilation causes engorgement of sinusoidal spaces in the corpus cavernosum. In the absence of sexual stimuli, however, nothing will happen. D. A fatty meal delays absorption, and, as a result, plasma levels peak in 2 hours instead of an hour; it does not cause sildenafil to be ineffective.
