RPN Maternal and Newborn Care 4

Question 1

A nurse is preparing to administer vitamin K to a newborn. Which statement best explains the rationale for this injection?

Accepted Answer

Newborns lack intestinal bacteria needed to synthesize vitamin K, increasing bleeding risk

Answer

Newborns are born without intestinal flora that synthesize vitamin K, making them susceptible to hemorrhagic disease of the newborn.

Question 2

A postpartum client on day 2 reports calf pain, warmth, and redness in her left leg. Which nursing action takes priority?

Accepted Answer

Notify the provider and avoid massaging the leg

Answer

These signs suggest deep vein thrombosis; the nurse must notify the provider and avoid massaging the leg to prevent embolization.

Question 3

Which assessment best confirms that a newborn has passed the initial gastrointestinal transition successfully?

Accepted Answer

Passage of meconium within 24–48 hours

Answer

Passage of meconium within the first 24–48 hours confirms patency of the gastrointestinal tract.

Question 4

A nurse is caring for a client in transition phase of labor who is 8 cm dilated. She begins hyperventilating. What is the most effective initial intervention?

Accepted Answer

Have the client breathe slowly and deeply with coaching

Answer

Coaching slow, paced breathing corrects the respiratory alkalosis caused by hyperventilation and is the safest immediate intervention.

Question 5

A nurse notes that a newborn's umbilical cord has one artery and one vein instead of the normal two arteries and one vein. What is the most important follow-up action?

Accepted Answer

Notify the provider, as this may indicate renal or cardiac anomalies

Answer

A single umbilical artery (two-vessel cord) is associated with renal, cardiac, and chromosomal anomalies and must be reported to the provider.
