Metronidazole
Phenytoin
Prednisone
Isosorbide
The Correct Answer is D
Rationale:
A. Metronidazole: Metronidazole is an antibiotic and does not have significant interactions with sildenafil.
B. Phenytoin: Phenytoin is an anticonvulsant medication and does not have significant interactions with sildenafil.
C. Prednisone: Prednisone is a corticosteroid and does not have significant interactions with sildenafil.
D. Isosorbide: Isosorbide is a nitrate medication used to treat angin
A. Combining sildenafil with nitrate medications can lead to severe hypotension and is contraindicated. Sildenafil potentiates the vasodilatory effects of nitrates, which can result in a dangerous drop in blood pressure.

Correct Answer is []
Explanation
Potential condition
Correct Answer: B. Meningocele
Rationale: Based on the provided physical examination details, the newborn is most likely experiencing a meningocele, which is indicated by the presence of a sac in the lumbar area. This condition is a type of neural tube defect where a sac of fluid comes through an opening in the baby's back. However, the absence of other neurological symptoms and the intactreflexes suggest that the condition has not severely affected the newborn's neurological functions.
Actions to Take (2)
Correct Answers: C, E
The two actions the nurse should take to address this condition include: applying a non-adhering sterile saline moist compress to the sac to prevent it from drying and to protect it from trauma, and educating the guardians about the condition, its implications, and the potential need for surgical intervention to repair the defect.
Parameters to monitor
Correct Answer: A, C
Rationale: The two parameters the nurse should monitor to assess the newborn's progress are the head circumference and serial head ultrasounds. Monitoring head circumference is crucial as an increase may indicate hydrocephalus, which can be associated with meningocele. Serial head ultrasounds are necessary to assess for any changes in the brain structure or development of hydrocephalus. These measures will help ensure that any complications are identified and managed promptly.
Correct Answer is D
Explanation
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.
