In assessing a 2-year-old boy with croup, the practical nurse (PN) finds that he has become increasingly irritable and has developed tachypnea and resting stridor. Which intervention is best for the PN to implement?

The correct answer is choice A: Never scratch under the cast.

Choice A rationale:

It is important not to scratch under the cast because inserting objects can lead to skin injury and infection. If itching occurs, blowing cool air from a hair dryer into the cast is recommended.

Choice B rationale:

While mild swelling and some discomfort are common after a cast is applied, patients should not expect an increase in pain. Persistent or severe pain could indicate complications such as increased swelling, decreased blood flow, or pressure on nerves and should be evaluated by a healthcare provider.

Choice C rationale:

Applying a cold pack to “hot spots” on the cast is not recommended as it can lead to moisture accumulation and skin problems. Instead, to manage swelling and discomfort, ice can be applied over the cast, covered with a thin towel, for 20 minutes every two hours while awake during the first 48 hours.

Choice D rationale:

Keeping the injured leg in a dependent position is not advised because it can increase swelling and pain. The affected limb should be elevated above the level of the heart to reduce swelling and promote healing.

The correct answer is Choice D

Choice A: Excruciating pain

• Rationale: While partial thickness burns can be painful, especially in the first few days, excruciating pain is less likely for a stable patient 3 days post-burn. Pain management is a crucial aspect of burn care, but excruciating pain might indicate deeper burns or complications like infection.

Choice B: Elevated blood pressure

• Rationale: Elevated blood pressure is not a typical complication of a partial thickness burn. In fact, burn patients are more at risk for hypotension (low blood pressure) due to fluid loss.

Choice C: Compartment syndrome

• Rationale: Compartment syndrome is a serious complication that typically occurs with deep burns or traumatic injuries. It's caused by increased pressure within a muscle compartment, restricting blood flow and potentially leading to tissue death. While a possibility, it's less likely for a partial thickness burn 3 days after the injury.

Choice D: Curling's Ulcer

• Rationale: Curling's ulcer is a peptic ulcer (stomach ulcer) that can develop as a complication of major burns. This is because burns trigger a massive inflammatory response, releasing stress hormones that increase stomach acid production, making the stomach lining more susceptible to ulcers. Given the extensive burn area (30% TBSA) and the timeframe (3 days post-burn), Curling's ulcer becomes a significant concern.

Therefore, the correct answer is: Choice D: Curling's Ulcer

Explanation:

• A 30% TBSA partial thickness burn is a significant injury that triggers a systemic inflammatory response.
• Three days post-burn falls within the timeframe when Curling's ulcer can develop due to the increased stress hormones and gastric acid production.
• While pain management and monitoring for compartment syndrome are important, Curling's ulcer poses a more significant threat in this scenario.
