A nurse is planning to reinforce teaching with a preschooler who is about to undergo an incision and

drainage for cellulitis on the left arm. Which of the following techniques should the nurse use?

Choice A rationale:

Uterine rupture typically presents with intense, constant abdominal pain and signs of shock. However, the absence of visible bleeding in the abdominal cavity makes this choice less likely in this case.

Choice B rationale:

Placental abruption involves the premature separation of the placenta from the uterine wall before delivery. The sudden, severe abdominal pain, moderate vaginal bleeding, persistent uterine contractions, and signs of hypovolemic shock (low blood pressure, rigid abdomen) are indicative of placental abruption. This condition requires immediate medical intervention due to the risk of fetal and maternal compromise.

Choice C rationale:

Placenta previa occurs when the placenta partially or completely covers the cervical opening. It typically presents with painless, bright red vaginal bleeding. The severe abdominal pain described in the scenario is inconsistent with placenta previa.

Choice D rationale:

Amniotic fluid embolus is a rare and life-threatening condition in which amniotic fluid enters the maternal bloodstream, causing an allergic reaction. It can lead to sudden cardiovascular collapse. Although it can cause respiratory distress and hypotension, it does not usually present with severe abdominal pain or uterine contractions.

Choice A rationale:

Repositioning the NG tube is not the appropriate action for hyperosmolar dehydration. This condition occurs due to an excessive concentration of solutes in the body, leading to a decrease in intracellular water. Repositioning the tube would not address the hyperosmolarity issue.

Choice B rationale:

Increasing the rate of formula delivery may exacerbate the problem by introducing more concentrated formula into the client's system, worsening hyperosmolarity. This choice can lead to further dehydration and electrolyte imbalances.

Choice C rationale:

Adding water to the formula is the correct action in this scenario. Hyperosmolar dehydration requires dilution of the concentrated formula to reduce the osmolarity. By adding water to the formula, the nurse can decrease the concentration of solutes, helping to rehydrate the client effectively.

Choice D rationale:

Switching to a lactose-free formula is not the appropriate intervention for hyperosmolar dehydration. The issue lies in the concentration of the formula, not in its lactose content. Adding water is the more suitable and direct approach to address the problem.
