Maternal Newborn Nursing Test Newborn Pharmacology and Procedures 2

Question 1

Which finding would indicate a complication following a heel stick blood collection on a newborn?

Accepted Answer

Calcified nodule or scar formation at the puncture site from repeated sticks

Answer

Repeated heel sticks in the same area can cause calcified nodules (calcinosis cutis) or scarring; sites should be rotated and the lateral aspects of the heel used to prevent this complication.

Question 2

A nurse is preparing to perform a circumcision care assessment. Which finding at the circumcision site requires provider notification?

Accepted Answer

Purulent yellow discharge, peri-wound erythema spreading beyond the glans, and fever

Answer

A thin yellow pseudomembrane forming over the glans is normal healing; spreading erythema, purulent discharge, and fever indicate infection requiring provider evaluation.

Question 3

Which pain management intervention is evidence-based for use during painful newborn procedures such as heel sticks?

Accepted Answer

Oral sucrose solution given 2 minutes before the procedure

Answer

Oral sucrose (24% solution, 0.5–2 mL) administered 2 minutes before painful procedures activates endogenous opioid pathways and reduces behavioral pain responses in newborns.

Question 4

A nurse is caring for a premature newborn at 30 weeks gestation who requires surfactant therapy. Which condition is this treatment intended to address?

Accepted Answer

Respiratory distress syndrome (RDS) caused by insufficient surfactant production

Answer

Preterm infants lack sufficient surfactant, leading to alveolar collapse and RDS; exogenous surfactant therapy reduces surface tension, improves lung compliance, and decreases mortality.

Question 5

A newborn is ordered to receive ampicillin and gentamicin for suspected sepsis. Which nursing assessment is essential before administering gentamicin?

Accepted Answer

Serum creatinine and BUN to assess renal function, and urine output

Answer

Gentamicin is nephrotoxic and ototoxic; renal function (creatinine, BUN, urine output) must be assessed before each dose, and peak/trough levels monitored to prevent toxicity.
