Final answer:
The nurse should first attend to the postpartum patient with bright red bloody discharge as it indicates a potentially life-threatening postpartum hemorrhage.
Step-by-step explanation:
The nurse should see the patient with 5 days postpartum, bright red bloody discharge first. This could be a sign of postpartum hemorrhage, a potentially life-threatening condition that requires immediate attention. The lack of fetal heart tones at 6 weeks gestation using a Doppler is concerning, but not necessarily an emergency at this stage, as heart tones are often not detected until 10-12 weeks with a Doppler.
22 weeks gestation feeling fetal movement is normal and not an urgent concern. 2 days postpartum, having urinary incontinence is concerning for the patient's comfort and quality of life, but it is not as immediate a threat to life as potential hemorrhage. The LPN not being able to get fetal heart tones at 6 weeks gestation is not an immediate concern since it is still early in the pregnancy and fetal heart tones may not be easily detected yet.
