A pregnant adolescent female is diagnosed with iron deficiency anemia and treated with elemental iron. To determine the effectiveness of the supplementation, the nurse practitioner instructs the adolescent to return:
for a CBC 4 weeks after initiating therapy.
for an Hgb/Hct level 4 weeks after initiating therapy.
for an Hgb level 8 weeks after initiating therapy.
for a serum ferritin level 10 weeks after initiating therapy.
The Correct Answer is B
Rationale:
A. A complete blood count (CBC) includes multiple parameters, but for monitoring iron therapy specifically, hemoglobin and hematocrit are the primary indicators.
B. Hemoglobin (Hgb) and hematocrit (Hct) levels should be rechecked approximately 4 weeks after starting elemental iron supplementation to assess for response to therapy and ensure that anemia is improving.
C. Waiting 8 weeks is longer than necessary to detect an initial therapeutic response; early monitoring helps adjust dosing if needed.
D. Serum ferritin reflects iron stores but is less commonly used for short-term monitoring of therapy response in pregnant adolescents. Hgb/Hct provide more immediate indicators of treatment effectiveness.

Correct Answer is A
Explanation
Rationale:
A. Newborns delivered before 37 completed weeks of gestation are considered preterm. Those born at less than 34 weeks are classified as early or very preterm, reflecting increased risk for complications due to organ immaturity.
B. Late preterm refers to infants born between 34 and 36 weeks’ gestation.
C. Term refers to infants born between 37 and 41 weeks of gestation.
D. Postterm refers to infants born at 42 weeks of gestation or later.
Correct Answer is B
Explanation
Rationale:
A. Caput succedaneum is edema of the scalp that crosses suture lines and results from pressure on the presenting part during delivery, not a true hemorrhage.
B. Cephalohematoma is a subperiosteal hemorrhage, meaning blood collects between the periosteum and the skull bone. It is typically firm, well-defined, and does not cross suture lines. It may appear several hours after birth and usually resolves spontaneously over weeks to months.
C. Subdural hemorrhage involves bleeding beneath the dura mater, often associated with trauma or birth complications, but it is deeper than a cephalohematoma and may cause neurological signs.
D. Subarachnoid hemorrhage occurs in the space between the arachnoid and pia mater; it is not limited to the periosteum and is rare in uncomplicated deliveries.
