The nurse explains that the medication Prostaglandin E1 is being given to their child with transposition of the great vessels to:

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.

A.Altered level of consciousness and thready pulse.

In a child after heart surgery to correct Tetralogy of Fallot (TOF), a thready pulse and altered level of consciousness can be indicative of poor cardiac output. This may suggest that the heart is not effectively pumping blood to meet the body's needs.

B. Bounding pulses and mottled skin: Bounding pulses and mottled skin are not typical signs of decreased cardiac output. Bounding pulses are often associated with increased cardiac output.

C. Capillary refill of 2 seconds and blood pressure of 96/47 mmHg: A capillary refill of 2 seconds is within the normal range, and a blood pressure of 96/47 mmHg is reasonable for a child. These findings do not necessarily indicate poor cardiac output.

D. Extremities warm to the touch and pale skin: Warm extremities and pale skin are not typical signs of decreased cardiac output. Cold extremities and cyanosis may be more concerning signs.
