Correct Answer is A
Explanation
A. The lecithin/sphingomyelin (L/S) ratio assesses fetal lung maturity. A higher ratio indicates that the baby's lungs are mature enough to handle breathing air outside the womb, which is the primary purpose of this test.
B. The L/S ratio test does not assess placental function. Placental function is evaluated through other tests, such as Doppler studies or biophysical profiles.
C. The L/S ratio test is not related to Rh incompatibility. Rh incompatibility issues are managed through different assessments, such as the Coombs test and Rh factor screening.
D. The L/S ratio test does not indicate genetic disorders. Genetic disorders are assessed through tests like amniocentesis or chorionic villus sampling, not the L/S ratio.
Correct Answer is C
Explanation
A. Blood pressure 156/80 mm Hg is incorrect. While this blood pressure reading is elevated, hypertension is not a typical immediate sign of postpartum hemorrhage. Hemorrhage is more commonly associated with hypotension (low blood pressure) due to fluid loss.
B. Temperature 38.3° C (101° F) is incorrect. A mild fever may be common in the first 24 hours postpartum due to normal inflammatory responses. It is not specifically indicative of postpartum hemorrhage, though a persistent fever could indicate an infection.
C. Respiratory rate 32/min is correct. An increased respiratory rate can be a sign of hypovolemia (due to significant blood loss), which may occur with postpartum hemorrhage. The body compensates for decreased blood volume by increasing the respiratory rate.
D. Apical pulse 66/min is incorrect. A heart rate of 66/min is within normal limits and would not be indicative of postpartum hemorrhage. In fact, a tachycardic (elevated) heart rate is more concerning in the case of hemorrhage as the body tries to compensate for blood loss.
