Final answer:
The HCP may prescribe phosphodiesterase type 5 inhibitors like Viagra® or Cialis® for ED, which increase blood flow to the pen_is. If these are unsuitable, vacuum pumps or penile implants could be alternatives.
Step-by-step explanation:
When considering medications for erectile dysfunction (ED), an Emergency Department (ED) Registered Nurse (RN) should anticipate the Health Care Provider (HCP) to prescribe phosphodiesterase type 5 inhibitors, commonly known by brand names such as Viagra® (sildenafil) and Cialis® (tadalafil). These medications are effective for treating ED because they help by increasing blood flow to the pen_is. In situations where prescription drugs might not be suitable or have failed, other treatments such as vacuum pumps, or more invasive procedures like penile implants, might be considered as alternative options.
