Which factor is most important in predisposing toddlers to frequent infections such as otitis media, tonsillitis, and upper respiratory tract infections?

Brian playing with his truck next to Kristina playing with her truck. This is because parallel play is when children play side by side with similar toys but do not interact with each other. Parallel play is typical for toddlers and preschoolers.

Choice A is wrong because Kimberly and Amanda sharing clay to each make things is an example of cooperative play, which involves sharing, taking turns, and following

rules. Cooperative play is typical for school-age children.

Choice C is wrong because Adam playing a board game with Kyle, Steven, and Erich is also an example of cooperative play, as they are playing by the same rules and interacting with each other.

Choice D is wrong because Danielle playing with a music box on her mother’s lap is an example of solitary play, which is when a child plays alone and does not seek contact with others. Solitary play is typical for infants.

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.
