RESP 202 EXAM 5

Why does meconium staining generally occur in infants > 36 weeks of age?

• Because these infants can generate strong inspiratory efforts

• Because infants this age have significant cardiac outputs

• Because these infants demonstrate strong peristalsis

• Because newborns have powerful anal sphincter tone

What intervention should be taken when a baby is born with choanal atresia?

• Perform nasotracheal intubation

• Recommend a tracheostomy

• Insert an oropharyngeal airway

• Perform cricothyroidotomy

Why are term or near term infants commonly overlooked as a group of patients at risk for developing IRDS?

• Because these infants tend to be strong and have excellent pulmonary reserve

• Because the mothers appear generally healthy

• Because these infants have large cardiac outputs

• Because these infants can compensate with increased renal function

What is the significance of an infant with IRDS demonstrating a grunt during each exhalation?

• Resolution of RDS

• An effort to maintain FRC

• An attempt to overcome increased airway resistance

• Impending death

Blood samples are taken from both the right radial artery and the umbilical artery. The PaO2 from the right wrist is 20 mmHg higher than that analyzed from the UAC. On the basis of these findings, which condition does the infant likely have?

• RDS

• MAS

• PPHN

• Neonatal pneumonia

What is the role of radiography in the determination of TE fistula and esophageal atresias?

• The esophageal pouch can be observed

• The opening into the airway can be located

• The presence of a left to right shunt can be seen

• The location of the NG tube may confirm obstruction of the proximal esophagus caused by the atresia

What is the most common complaint associated with pectus carinatum?

• No complaints

• Dyspnea at rest

• Cosmetic

• Cardiac palpitations

PPHN can be associated with which underlying pulmonary disorder

• MAS

• RDS

• None (idiopathic)

• AOTA

What is the most important cause of IVH?

• PPV

• Hypoxemia and respiratory failure

• Lack of autoregulation and resulting fluctuations in cerebral blood flow

• Intravascular administration of glucose and other nutrients

• Administration of medications used to close a PDA

When comparing gastroschisis and omphalocele, which of the following is true?

• They are both full thickness defects of the abdominal wall

• They both are commonly associated with other anomalies

• Omphalocele is a midline defect, while a gastroschisis is a lateral wall defect

• An omphalocele is covered by epidermal tissue

• Gastroschisis requires surgical reductions that frequently must be performed in several stages, while omphalocele is completed in a single surgery
