A nurse in a provider's clinic is caring for a client who reports erectile dysfunction and requests a prescription for sildenafil. Which of the following medications currently prescribed for the client is a contraindication to taking sildenafil?

Rationale:

A. "Your baby should sleep at least 6 hours between feedings.": Newborns typically wake every 2-3 hours for feeding, so sleeping for 6 hours between feedings is not indicative of adequate breastfeeding.

B. "Your baby should burp after each feeding.": Burping is important for gas relief but does not necessarily indicate sufficient breastfeeding.

C. "Your baby should have a wake cycle of 30 to 60 minutes after each feeding.": The wake cycle after feeding is not a reliable indicator of sufficient breastfeeding.

D. "Your baby should wet 6 to 8 diapers per day.": Monitoring the number of wet diapers is a

reliable indicator of adequate breastfeeding. A newborn who is getting enough breast milk should produce at least 6 to 8 wet diapers per day, indicating sufficient hydration and nutrient intake.

The nurse should anticipate a provider prescription for an antiviral medication, as evidenced by the client's presentation of small pinpoint open vesicles and pustules on the labia majora, which are indicative of a herpes simplex virus infection, a common cause of genital ulcers. The clear drainage and absence of pain are consistent with this diagnosis. Additionally, the thick, mucopurulent discharge could suggest a secondary bacterial infection, for which the provider may prescribe antibiotics.

Antiviral medication is likely prescribed for perineal lesions because these can be indicative of a viral infection, such as herpes. The nurse should recognize the need for antivirals to manage and treat the underlying cause.
