A client is noted to have type I hypersensitivity reaction with a systemic response. Which clinical manifestations should the nurse anticipate? (Select all that apply).

A. Complete Heart Block: Complete heart block (third-degree AV block) occurs when there is no communication between the atria and ventricles. The atria and ventricles beat independently, resulting in a very slow ventricular rate. This rhythm is characterized by regular P waves that have no relation to the QRS complexes.

B. Sinus Tachycardia: Sinus tachycardia is a rhythm originating from the sinoatrial node with a heart rate typically between 100-150 beats per minute. The rhythm is regular, and the P waves precede each QRS complex consistently.

C. Ventricular Tachycardia: Ventricular tachycardia is a fast heart rhythm that originates from the ventricles. It is characterized by wide and abnormal QRS complexes with a rate usually between 150-250 beats per minute. There may be no visible P waves, and if present, they are not associated with the QRS complexes.

D. Idioventricular Rhythm: Idioventricular rhythm is a slow rhythm originating from the ventricles with a heart rate usually between 20-40 beats per minute. It has wide and abnormal QRS complexes and no visible P waves.

A. Dyspnea: Worsening dyspnea may indicate complications such as heart failure or embolization of infectious material to the lungs, which can occur in infective endocarditis as a result of vegetation formation on heart valves. Dyspnea can suggest decreased cardiac output or pulmonary involvement, indicating a worsening condition.

B. Malaise: Malaise is a nonspecific symptom that is common in infective endocarditis due to systemic infection and inflammation. While it can be present in both mild and severe cases, it may not specifically indicate worsening of the condition without other signs of deterioration.

C. Fever: Fever is a hallmark symptom of infective endocarditis and may persist or worsen with progressive infection. However, fever alone may not necessarily indicate worsening if the client is already febrile due to the underlying infection.

D. Anorexia: Anorexia or loss of appetite can occur in infective endocarditis due to systemic illness but may not specifically indicate worsening without other signs of deterioration. It is important to assess for other signs of worsening condition, such as hemodynamic instability or embolic events, in conjunction with anorexia.
