A nurse is caring for a client who is at 37 weeks of gestation and reports a slow trickle of vaginal fluid for the past 12 hr. Which of the following diagnostic tests should the nurse anticipate?
Speculum exam to test for fetal fibronectin
Amniocentesis to determine fetal lung maturity
Urinalysis to determine protein content
Vaginal swab for nitrazine testing
The Correct Answer is D
A. Fetal fibronectin testing is used to assess risk for preterm labor, not to confirm rupture of membranes.
B. Amniocentesis for fetal lung maturity is generally not needed at 37 weeks or later.
C. Urinalysis is for urinary tract issues, not for detecting amniotic fluid.
D. Nitrazine testing helps determine if vaginal fluid is amniotic fluid by assessing pH, aiding in diagnosing rupture of membranes.

Correct Answer is ["C","D"]
Explanation
A. Supplement feedings with dextrose water – Dextrose water is not appropriate for newborn feeding. It lacks the necessary calories and nutrients and is not recommended for managing hyperbilirubinemia or hydration.
B. Administer intravenous dextrose – There is no evidence of hypoglycemia or need for IV fluids. This is not indicated based on the current assessment.
C. Obtain a total serum bilirubin – The yellow sclera and cephalohematoma (from vacuum-assisted birth) place the newborn at risk for hyperbilirubinemia. A serum bilirubin level is needed to assess severity.
D. Encourage breastfeeding every 2 hr – This promotes bilirubin excretion through stools and urine, which is essential in managing or preventing jaundice in newborns.
E. Prepare for an exchange transfusion – This is a treatment for severe hyperbilirubinemia or hemolytic disease, and is not indicated at this stage without bilirubin results.
F. Obtain blood cultures – The mother received appropriate intrapartum prophylaxis (2 doses of penicillin G) for GBS. The newborn shows no signs of sepsis (vital signs normal, active, feeding), so cultures are not indicated now.

Explanation
Desired dose = 50 mcg
Available = 200 mcg per tablet
Number of tablets = Desired dose ÷ Available dose
