A nurse on a pediatric unit is caring for a toddler who has poor dietary intake. Which of the following actions should the nurse take first?

A. Ensure that the client gave informed consent. Confirming that the client has provided informed consent is a critical step before any invasive procedure, including an esophagogastroduodenoscopy (EGD). The nurse should ensure that the client understands the procedure, its risks, benefits, and any alternatives before the procedure begins.
B. Administer an oral contrast solution. Oral contrast is typically not used for an EGD, as the procedure involves direct visualization of the esophagus, stomach, and duodenum. Instead, the client may need to follow specific dietary restrictions prior to the procedure, such as fasting.
C. Ensure that the client's bladder is full. A full bladder is not required for an EGD. In fact, it is more important for the client to be in a comfortable position and relaxed during the procedure. An empty stomach is preferred to reduce the risk of aspiration.
D. Inform the client the procedure will take 60 min. While informing the client about the duration of the procedure is important, the exact time can vary. Providing a range or informing the client that the procedure may take some time is more appropriate, as it helps manage expectations without causing unnecessary anxiety.

A. Clear rhinorrhea. Mild respiratory illnesses, such as a common cold with clear nasal discharge, do not contraindicate varicella vaccination. The immunization can still be administered unless the child has a moderate to severe illness with fever.
B. Medications for a cardiac anomaly. Having a congenital heart defect or taking cardiac medications does not typically contraindicate varicella vaccination. However, children on high-dose immunosuppressive therapy for heart conditions may need further evaluation before receiving live vaccines.
C. Chemotherapy treatments. Chemotherapy suppresses the immune system, increasing the risk of severe complications from live vaccines like varicella. Children undergoing chemotherapy should not receive live-virus vaccines until immune function has sufficiently recovered, as determined by a healthcare provider.
D. Two diarrhea stools in the last day. Mild, self-limiting diarrhea does not contraindicate vaccination. Only children with severe acute gastrointestinal illness should have vaccinations postponed until they recover.
