What assessment is necessary for a client after a splenectomy who presents with fever?

The correct assessment to conduct for a client who has undergone a splenectomy and presents with fever is to evaluate for signs of infection. Following the removal of the spleen, the body's ability to filter bacteria and respond to infections is impaired due to the loss of its immunological functions. The spleen plays a crucial role in the immune system, particularly in fighting encapsulated organisms. Patients who have had a splenectomy are at a higher risk for developing infections, especially those caused by bacteria such as Streptococcus pneumoniae and Haemophilus influenzae.

Even a mild fever in a post-splenectomy patient warrants a careful examination for any signs or symptoms of infection, as the risk of sepsis is significantly increased. This involves checking for localized signs of infection (like redness, swelling, or discharge) as well as systemic signs such as increased heart rate, low blood pressure, or altered mental status.

While monitoring for respiratory distress, assessing for allergic reactions, and checking for gastrointestinal bleeding are all important assessments in various clinical contexts, they are not specific to the concerns raised by a fever in a patient post-splenectomy. The priority in this situation should be on identifying potential infections due to the decreased immunological protection.
