A nurse is admitting an infant who has severe dehydration from acute gastroenteritis. Which of the following findings should the nurse expect?

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.

Severe anemia is a condition characterized by a significant decrease in the number of red blood cells or hemoglobin in the blood, leading to reduced oxygen-carrying capacity. This can result in fatigue, weakness, and shortness of breath in the affected individual.

A red blood cell transfusion is given to a child with severe anemia to increase the number of red blood cells and, consequently, the hemoglobin level in the blood. This helps improve oxygen delivery to tissues and organs, which can lead to increased energy levels and reduced fatigue.

Option A is incorrect because red blood cell transfusion is not given to help the body stop bleeding by forming a clot. Platelets are responsible for clot formation, not red blood cells.

Option B is incorrect because a red blood cell transfusion is not used to fight infections. White blood cells and the immune system are responsible for fighting infections.

Option D is incorrect because a red blood cell transfusion is not given to allow her parents to come to visit her. Transfusions are medical treatments to address specific medical conditions and are not related to visitation rights.
