A school-aged child with a fracture of the femur near the epiphyseal plate is admitted to the hospital. The parents ask if there will be any after effects when the bone heals. Which physiological characteristic of the femur should the nurse consider when preparing to respond?

Growth of that leg may be affected.

Risk for infection at this location is increased

Long bones contain marrow, which increases the risk for anemia

Fracture repair will necessitate prolonged traction

Answer and Explanation

The Correct Answer is A

A.Growth of that leg may be affected.

When a fracture occurs near the epiphyseal plate of a long bone, such as the femur, there is a risk of damage to the growth plate. The growth plate (epiphyseal plate) is responsible for longitudinal bone growth in children. If the growth plate is injured or damaged during the fracture, it can potentially lead to growth disturbances and affect the growth of that leg.

B. Risk for infection at this location is increased: While any fracture has a risk of infection, the proximity to the epiphyseal plate doesn't necessarily increase the risk of infection.

C. Long bones contain marrow, which increases the risk for anemia: The presence of bone marrow in long bones is unrelated to the potential effects on bone growth after a fracture near the epiphyseal plate.

D. Fracture repair will necessitate prolonged traction: The use of traction for fracture repair can vary depending on the type and location of the fracture. However, the primary concern with a fracture near the epiphyseal plate is its potential impact on bone growth.

Correct Answer is C

Explanation

A. Shunted past the pulmonary circulation, causing pulmonary hypoxia: This option is not the primary reason for dyspnea in PDA. While there is shunting, it doesn't directly cause pulmonary hypoxia.

B. Circulated through the lungs again, causing pulmonary circulatory congestion: This option is partially correct but does not address the primary reason for dyspnea, which is the bypassing of the left side of the heart.

C. Circulated through the ductus from the pulmonary artery to the aorta, bypassing the left side of the heart.

In patent ductus arteriosus (PDA), a fetal blood vessel called the ductus arteriosus fails to close after birth. This allows oxygenated blood from the left atrium to be shunted directly from the aorta to the pulmonary artery, bypassing the normal route through the left side of the heart and into the systemic circulation. The shunting of oxygenated blood back into the pulmonary circulation can lead to increased pulmonary blood flow and circulatory congestion, causing symptoms such as dyspnea.

D. Shunted past cardiac arteries, causing myocardial hypoxia: PDA primarily affects the pulmonary circulation and left side of the heart, not the coronary arteries. Myocardial hypoxia is not the primary mechanism of dyspnea in PDA.

A. Pyloric stenosis B. Enterocolitis C. Encopresis D. Hirschsprung's disease

Correct Answer is D

Explanation

A.Pyloric stenosis is a condition where there's narrowing of the opening between the stomach and the small intestine. It is not related to inadequate motility of the intestine.

B.Enterocolitis refers to inflammation of the small intestine and colon. While this can cause obstruction in some cases, it's not the primary cause of inadequate motility as seen in the question.

C.Encopresis is the voluntary or involuntary passage of feces outside the toilet in children who should be toilet trained. It is not a cause of mechanical intestinal obstruction.

D. Hirschsprung's disease is a congenital disorder where there is inadequate motility in part of the intestine, leading to mechanical obstruction. It usually affects the colon and is due to the absence of ganglion cells in the affected segment of the bowel.

So, Hirschsprung's disease is the specific condition that leads to inadequate motility and mechanical obstruction of part of the intestine in infants.
