Maternal Newborn Nursing Test Newborn Pharmacology and Procedures 3

Question 1

A nurse is preparing a newborn for phototherapy to treat hyperbilirubinemia. Which nursing intervention is essential?

Accepted Answer

Cover the eyes with opaque eye patches and expose maximum skin surface to the light

Answer

Phototherapy works by converting bilirubin in the skin to a water-soluble form for excretion; eye patches protect against retinal damage, and maximum skin exposure increases effectiveness.

Question 2

Which laboratory test monitors the effectiveness of phototherapy for neonatal jaundice?

Accepted Answer

Serial total serum bilirubin (TSB) levels every 4–6 hours during therapy

Answer

Serial total serum bilirubin levels guide phototherapy management; if TSB continues to rise despite therapy, exchange transfusion may be needed.

Question 3

A nurse administers a neonatal blood transfusion. Which finding during the transfusion requires immediately stopping it?

Accepted Answer

Temperature rise of 1°C, tachycardia, and increasing respiratory rate

Answer

Fever, tachycardia, and increasing respiratory rate during blood transfusion indicate a transfusion reaction; the transfusion must be stopped immediately and the provider notified.

Question 4

Which method is used to verify placement of a nasogastric (NG) tube in a newborn before feeding?

Accepted Answer

Aspirate gastric contents and confirm pH ≤5 along with measuring the external tube length

Answer

NG tube placement is verified by pH testing of aspirated gastric contents (pH ≤5 confirms gastric placement) and confirming the external tube length matches pre-insertion measurement.

Question 5

A preterm newborn at 28 weeks is receiving total parenteral nutrition (TPN). Which complication should the nurse monitor for most closely?

Accepted Answer

Hyperglycemia and catheter-related bloodstream infection (CRBSI)

Answer

Preterm neonates on TPN are at high risk for hyperglycemia (immature glucose regulation) and CRBSI from central line use; blood glucose and infection signs must be monitored closely.
