A nurse is preparing to administer levothyroxine 0.175 mg PO once a day. The amount available is levothyroxine 88 mcg/tablet. How many tablets should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero)

A white glow of the pupil, often referred to as "cat's eye reflex" or "leukocoria," is a significant and characteristic sign of retinoblastoma. It occurs when the tumor within the eye reflects light, resulting in a white or yellowish glow in the pupil when light is shined into it. This can be seen in flash photographs or in certain lighting conditions. It's a crucial sign that may indicate the presence of retinoblastoma, a rare eye cancer that primarily affects young children.

The other options, B (ptosis of the eye), C (fixed and dilated pupil), and D (purulent eye discharge), are not typically associated with retinoblastoma. Ptosis is the drooping of the upper eyelid, a fixed and dilated pupil is usually a sign of neurological issues, and purulent eye discharge is often associated with eye infections rather than retinoblastoma.

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.
