Final answer:
The finding that should be reported to the healthcare provider is the absence of fetal movement for 4 hours, as it may indicate fetal distress or other complications requiring immediate attention.
Step-by-step explanation:
The nurse in an antepartum clinic is assessing a client who is at 32 weeks gestation. Of the options provided, the finding that should be reported to the provider is D. Absence of fetal movement for 4 hours. Fetal heart rate of 150 beats/min is within the normal range for this stage of pregnancy. A fundal height of 30 cm is typically consistent with a gestational age of 30 weeks but can be normal as measurements can vary by a few centimeters. A maternal blood pressure of 90/60 mm Hg, while on the lower side, is not necessarily abnormal if there are no other symptoms of concern. However, a lack of fetal movement for 4 hours may indicate potential distress or complications, and it's important for the provider to evaluate this right away for further assessment.
