A male client who weighs 90 kg is admitted to the emergency department with full thickness burns to 45% of his total body surface area (TBSA). The burns occurred at 1000. At 1200, the nurse uses the prescribed protocol for burns fluid resuscitation to calculate the total fluid volume for the first 24 hours. The infusion pump should be set to deliver how many mL/hour during the first 8 hours? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["1350"]
Rationale:
Fluid resuscitation rate using the Parkland formula:
- Calculate the total fluid volume needed for the first 24 hours.
The Parkland formula: 4 mL × client weight (kg) × % TBSA burned.
Client weight = 90 kg
TBSA burned = 45%
Total fluid volume = 4 mL × 90 kg × 45 = 16,200 mL
- Determine the amount of fluid to be given in the first 8 hours.
According to the Parkland formula, half of the total fluid volume is administered in the first 8 hours from the time of the burn injury.
Fluid for first 8 hours = 16,200 mL / 2
= 8,100 mL
- Calculate the infusion rate for the first 8 hours.
The burn occurred at 1000. The nurse arrives at 1200. This means 2 hours have already passed since the burn occurred within the initial 8-hour period.
Remaining time in the first 8 hours = 8 hours - 2 hours
= 6 hours.
Infusion rate (mL/hour) = Fluid for remaining first 8 hours / Remaining time in first 8 hours
= 8,100 mL / 6 hours
= 1350 mL/hour.

Correct Answer is D
Explanation
A. Tacos: Tacos are often spicy and greasy, both of which can relax the lower esophageal sphincter and aggravate GERD symptoms in children by increasing acid reflux episodes.
B. Chocolate milkshake: Chocolate and high-fat dairy both reduce LES pressure and increase gastric acid secretion, worsening reflux. The milkshake also adds volume, which can trigger symptoms.
C. Pizza: Pizza is acidic (due to tomato sauce), high in fat, and often spicy—an unhealthy combination for a child with GERD. It’s one of the most commonly reported reflux-triggering foods.
D. Sugar cookies: Sugar cookies are bland, low in fat, and non-acidic, making them a safe snack choice for children managing GERD symptoms through dietary adjustments.
Correct Answer is B
Explanation
A. Recommend substituting opioids with other pain medication: Simply switching to another pain medication without addressing underlying misuse behaviors may reinforce dependency. This overlooks the denial and psychological aspects of addiction.
B. Explore other coping strategies aside from using medications: This client-centered approach gently addresses the issue without direct confrontation. It encourages self-reflection, promotes healthy alternatives, and meets the client where they are in terms of readiness for change, which is essential in early recovery.
C. Provide a list of local Narcotics Anonymous meetings: Although this is useful, offering it during the first interaction with a client in denial may lead to resistance. Engagement and trust-building through conversation about alternatives are more effective initially.
D. Explain that opioid abuse poses a great risk to life: Providing factual information about risk can be helpful, but directly labeling it as abuse when the client is in denial may trigger defensiveness. It is more therapeutic to explore behaviors and build insight before confrontation.
