A nurse is instilling otic drops into an 18-month-old child's ears. Which of the following methods should the nurse use?

A. "Gently put the tubes back into the child's ears": This is not the correct response. Tympanoplasty tubes are not meant to be reinserted if they fall out. Attempting to reinsert them without proper medical training could cause injury or damage to the child's ears. Therefore, this response should be avoided.

B. "Bring the child to the emergency department immediately": While it's important for the parent to seek medical attention if the tubes fall out, it may not always necessitate a visit to the emergency department, especially if the child is not experiencing any other symptoms. This response might cause unnecessary panic for the parent and may not be the most appropriate course of action.

C. "Notify the provider that the tubes have fallen out": This is the correct response. If the tympanoplasty tubes fall out, the parent should notify the healthcare provider who performed the procedure. The provider can then assess the situation and determine the next steps, which may include scheduling a follow-up appointment to evaluate the child's ears.

D. "The tubes are sutured in place and must be surgically removed": This is incorrect. Tympanoplasty tubes are not sutured in place; they are typically designed to fall out on their own after a certain period of time. Additionally, removal of tympanoplasty tubes usually does not require another surgical procedure.

A. Coarctation of the aorta

Coarctation of the aorta involves a narrowing of the aorta, leading to decreased blood flow to the lower body. It is not associated with increased pulmonary blood flow.

B. Patent ductus arteriosus

Patent ductus arteriosus (PDA) is a congenital heart defect where the ductus arteriosus, a fetal blood vessel that usually closes shortly after birth, remains open. This allows blood to flow from the aorta into the pulmonary artery, increasing pulmonary blood flow. Therefore, option B is correct.

C. Tetralogy of Fallot

Tetralogy of Fallot is a congenital heart defect characterized by four abnormalities, including a ventricular septal defect (VSD), pulmonary stenosis, right ventricular hypertrophy, and an overriding aorta. While it can lead to cyanosis due to right-to-left shunting, it is not primarily associated with increased pulmonary blood flow.

D. Tricuspid atresia

Tricuspid atresia involves the absence of the tricuspid valve, leading to a lack of direct blood flow from the right atrium to the right ventricle. It usually presents with decreased pulmonary blood flow rather than increased pulmonary blood flow.
