The nurse is talking to a parent of an infant with heart failure about feeding the infant. Which statement about feeding the child is correct?

Measles (rubeola) is a communicable disease that is characterized by Koplik’s spots, which are clustered, white lesions on the buccal mucosa opposite the lower molars. They appear two to three days before the measles rash and are pathognomonic for measles.

Choice A is wrong because rubella is a different viral infection that causes a mild rash and fever, but does not have Koplik’s spots.

Choice C is wrong because chickenpox (varicella) is caused by the varicella-zoster virus and produces fluid-filled blisters on the skin, not white spots in the mouth.

Choice D is wrong because exanthema subitum (roseola) is caused by the human herpesvirus 6 or 7 and causes a high fever followed by a pink rash on the trunk and neck, but no oral lesions.

Uterine atony.

This is when the uterus does not contract enough to stop the bleeding from the placental site after delivery. It is the most common cause of postpartum hemorrhage, accounting for up to 80% of cases. Uterine atony can be caused by factors such as prolonged or augmented labor, large baby, multiple pregnancies, infection, or retained placenta.

The woman in question has some risk factors for uterine atony, such as a large baby and augmentation of labor with Pitocin.

The other choices are wrong because:

A . Retained placental fragments: This is when parts of the placenta remain attached to the uterine wall and prevent it from contracting properly. It is the second most common cause of postpartum hemorrhage.

However, there is no indication in the question that the woman had any difficulty with the delivery of the placenta or that it was incomplete

B. Unrepaired vaginal lacerations: This is when there are tears or cuts in the vagina or cervix that cause bleeding. It is a less common cause of postpartum hemorrhage.

However, there is no indication in the question that the woman had any trauma during delivery or that she was examined for lacerations

D. Puerperal infection: This is when there is an infection in the uterus or other parts of the reproductive tract after delivery.

It can cause fever, pain, and bleeding. It is a rare cause of postpartum hemorrhage.

However, there is no indication in the question that the woman had any signs or symptoms of infection, such as fever, chills, or foul-smelling discharge.

Normal ranges for blood loss after delivery are less than 500 mL for vaginal birth and less than 1000 mL for C-section.

Any amount above these thresholds can be considered postpartum hemorrhage and requires prompt evaluation and treatment.
