A nurse is caring for a child who has Kawasaki disease. Which of the following systems should the nurse monitor in response to this diagnosis?

Rheumatic fever (RF) is a complication that can occur after an untreated or inadequately treated streptococcal throat infection (strep throat). It can affect the heart, joints, skin, and brain. One important aspect of managing RF is to prevent further episodes of strep throat, as it can trigger recurrent RF. Therefore, the child with a history of RF will require prophylactic antibiotics (usually penicillin or a related antibiotic) before certain invasive procedures, dental work, or surgeries to prevent strep throat and subsequent recurrence of RF.

Option A is not specific to rheumatic fever, and while electrolyte imbalances may be monitored and managed in certain cases of severe illness, it is not a core aspect of managing RF.
Option B is not accurate. While many children with RF do recover fully with appropriate treatment, they may be at risk of developing rheumatic heart disease, which can lead to long-term complications if not managed properly.
Option D is not a direct implication of RF. Rheumatic fever is not a genetically inherited condition, but a complication of strep throat caused by a bacterial infection. There is no evidence to suggest that having RF would directly affect the genetic implications for future offspring.

The nurse should clarify the prescription to administer sodium biphosphate/sodium phosphate because it is a laxative and is contraindicated in a child with suspected appendicitis. The use of laxatives or enemas can potentially worsen the condition by increasing the risk of perforation or rupture of the inflamed appendix.
A. Monitoring oral temperature every 4 hours is important to assess for signs of infection or worsening condition.
C. Maintaining NPO status is essential to avoid stimulating the digestive system and to prepare for possible surgery.
D. Medicating the client for pain every 4 hours as needed is appropriate to manage pain and provide comfort while the child awaits further evaluation or treatment.
Remember, it's crucial to avoid the use of laxatives, enemas, or any other interventions that can potentially aggravate the inflamed appendix in a child with suspected appendicitis.
