During a routine prenatal health assessment for a client in her third trimester, the client reports that she had fluid leakage on her way to the appointment.Which technique should the nurse implement to evaluate the leakage?

Choice A rationale Palpating the suprapubic area to assess fetal head position is not relevant to identifying the source of fluid leakage. This technique is used to evaluate fetal engagement in the pelvis, particularly near term, but it does not help in determining whether the fluid leakage is amniotic fluid or urine. Choice B rationale Scanning the bladder for urinary retention is unrelated to identifying the nature of fluid leakage. A bladder scan is useful for detecting residual urine volume in the bladder, often post-voiding, and is typically used in cases of urinary retention or post-operative care. Choice C rationale Testing the fluid with a nitrazine strip is a standard method to distinguish amniotic fluid from urine or vaginal secretions. Amniotic fluid has a higher pH (usually between 7.0 and 7.5), causing the nitrazine strip to turn blue, whereas urine and vaginal secretions usually have a lower pH, resulting in a yellow or green color on the strip. Choice D rationale Inserting a straight urinary catheter to drain the bladder is an invasive procedure that does not directly identify the source of fluid leakage. This technique is typically used to relieve urinary retention or to collect a sterile urine specimen, not for diagnosing amniotic fluid leakage.
