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?

D. A client's blood pressure changes from 112/60 mm Hg to 90/54 mm Hg when standing.
A significant drop in blood pressure when changing positions from lying to standing may indicate orthostatic hypotension, which can be a sign of dehydration, blood loss, or other underlying medical issues. This can be a cause for concern, especially if the client is an adolescent, as it may lead to decreased perfusion of vital organs and may require immediate medical attention.

The other options are as follows:
A. A client who has a burn injury to an estimated 5% of his leg and is crying - While it's essential to assess and address the client's pain and comfort, this finding does not indicate an immediate need for medical attention. Pain management and wound care can be addressed based on the severity of the burn and the client's pain level.
B. A client who has an ankle fracture reports a pain level increase from 3 to 5 after initial ambulation - This finding is concerning, and the nurse should notify the provider to reassess pain management and evaluate for potential complications related to the fracture. However, it may not require immediate medical attention unless there are signs of severe pain or complications.
C. A client who is 1 day postoperative and has a temperature of 37.5° C (99.5° F) - A slight increase in temperature in the immediate postoperative period may not be unusual and can be attributed to the normal inflammatory response after surgery. The nurse should continue monitoring the client's temperature and report any further changes or additional signs of infection or complications to the provider.
Overall, while all findings should be addressed and managed appropriately, the significant drop in blood pressure (option D) should be reported immediately due to the potential implications for the client's overall health and well-being.

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.
