A nurse on the postpartum unit is caring for a client who delivered vaginally 3 hr ago. Which of the following manifestations is a possible indication of postpartum hemorrhage?
Apical pulse 66/min.
Temperature 38.3 C (101° F).
Blood pressure 156/80 mm Hg.
Respiratory rate 32/min.
The Correct Answer is D
Choice A rationale
An apical pulse of 66/min is within the normal range and not indicative of postpartum hemorrhage, which would typically cause an elevated heart rate due to blood loss.
Choice B rationale
A temperature of 38.3°C (101°F) could indicate infection or inflammation but is not a direct sign of postpartum hemorrhage, which primarily involves significant blood loss.
Choice C rationale
Blood pressure of 156/80 mm Hg is elevated but not directly indicative of postpartum hemorrhage, which would typically result in a drop in blood pressure due to loss of blood volume.
Choice D rationale
A respiratory rate of 32/min is significantly elevated and can be a compensatory response to hypovolemia from postpartum hemorrhage. This response occurs as the body tries to increase oxygen delivery due to blood loss.

Correct Answer is ["C","E"]
Explanation
Choice A rationale
Douching is generally not recommended, especially during pregnancy, because it can disrupt the natural balance of bacteria in the vagina, potentially leading to infections or other complications.
Choice B rationale
Avoiding urination at bedtime is not advisable, as holding in urine can increase the risk of urinary tract infections (UTIs). Frequent urination is a good practice to help prevent and manage UTIs.
Choice C rationale
Wearing cotton-crotch underwear is recommended because cotton is breathable and helps to keep the genital area dry, reducing the risk of infections and irritation.
Choice D rationale
Eliminating yogurt products from the diet is not necessary; in fact, yogurt contains probiotics that can be beneficial for maintaining a healthy balance of bacteria in the gut and vaginal area.
Choice E rationale
Refraining from taking bubble baths is advised, as the chemicals in bubble bath products can irritate the urethra and increase the risk of UTIs.
Correct Answer is D
Explanation
Choice A rationale
Lecithin/sphingomyelin (L/S) ratio does not indicate genetic disorders; it's used to assess fetal lung maturity.
Choice B rationale
The test does not determine placental function. It specifically evaluates fetal lung maturity through the ratio of lecithin to sphingomyelin in amniotic fluid.
Choice C rationale
The test is not used to assess the risk of Rh incompatibility. The L/S ratio focuses on lung development rather than blood compatibility issues.
Choice D rationale
The L/S ratio assesses the baby's lung maturity, indicating if the lungs produce enough surfactant for proper function after birth.
