A nurse is assisting with the admission of a 9-year-old child who has acute rheumatic fever. When obtaining the client's history, it is appropriate for the nurse to ask the parent which of the following questions?

A. Drink eight glasses of fluid daily: This is crucial advice for patients with sickle cell anemia, as adequate hydration helps prevent sickling of red blood cells and reduces the risk of vaso-occlusive crises. Therefore, this precaution is appropriate and should be included in discharge teaching.

B. Maintain an updated Haemophilus influenzae type b (Hib) immunization: While vaccination is essential for overall health, maintaining Hib immunization is not directly related to sickle cell anemia or vaso-occlusive crises. However, it's still important for the child's general well-being and should be addressed but may not be the priority in discharge teaching for sickle cell anemia.

C. Avoid playground activities at school: Children with sickle cell anemia are at risk of vaso-occlusive crises triggered by dehydration, fatigue, or extreme physical exertion. While playground activities can be strenuous, completely avoiding them may not be necessary. Instead, the child should be educated on the importance of staying hydrated, taking breaks when needed, and avoiding excessive physical strain.

D. Assume postural drainage positions every 6 hours: Postural drainage is not typically indicated for sickle cell anemia or vaso-occlusive crises unless there are specific respiratory complications. This precaution is not relevant to the management of sickle cell anemia and should not be included in discharge teaching for this condition.

A. Machine-like murmur:

A machine-like murmur typically refers to a continuous murmur, which can be heard throughout systole and diastole. While machine-like murmurs can be associated with certain cardiac conditions, such as patent ductus arteriosus (PDA), they are not typically heard in coarctation of the aorta. In coarctation of the aorta, a systolic ejection murmur may be heard over the upper left sternal border due to turbulent blood flow across the narrowed aortic segment.

B. Severe cyanosis:

Cyanosis refers to a bluish discoloration of the skin and mucous membranes due to decreased oxygenation of the blood. While cyanosis can occur in various congenital heart defects, such as tetralogy of Fallot, it is not a characteristic manifestation of coarctation of the aorta. Coarctation of the aorta typically results in decreased blood flow to the lower extremities rather than mixing of oxygenated and deoxygenated blood.

C. Decreased blood pressure in the legs:

This is the correct choice. Coarctation of the aorta is characterized by narrowing of the aorta, which leads to decreased blood flow to the lower extremities. Consequently, blood pressure measurements in the legs may be lower compared to those in the arms. This finding is often a key indicator of coarctation of the aorta.

D. Pulmonary edema:

Pulmonary edema refers to the accumulation of fluid in the lungs and is typically associated with conditions such as heart failure or fluid overload. While some congenital heart defects may lead to heart failure and subsequent pulmonary edema, coarctation of the aorta does not directly cause pulmonary edema. Instead, it primarily affects blood flow to the lower extremities due to the narrowing of the aorta.
