1. The healthcare provider plans to administer 10 mcg/kg of digoxin elixir as a loading dose to a child who weighs 55 pounds. Digoxin is available as an elixir of 50 mcg/ml. How many milliliters of the digoxin elixir should the healthcare provider administer to this child?

• A. 5 ml
• B. 10 ml
• C. 15 ml
• D. 20 ml

Correct answer: A

Rationale: To calculate the dose, first, convert the child's weight to kilograms by dividing 55 pounds by 2.2, which equals approximately 25 kg. Then, multiply the weight by the dose (10 mcg/kg) to get the total dose needed, which is 250 mcg. Next, divide the total dose by the concentration of the elixir (50 mcg/ml) to determine the volume needed, which is 5 ml. Therefore, the correct dose is 5 ml based on the child's weight and the concentration of the elixir.

2. What intervention should the nurse implement first for a male toddler brought to the emergency center approximately three hours after swallowing tablets from his grandmother's bottle of digoxin (Lanoxin)?

• A. Administer activated charcoal
• B. Prepare gastric lavage
• C. Obtain a 12-lead electrocardiogram
• D. Give IV digoxin immune fab (Digibind)

Correct answer: A

Rationale: Administering activated charcoal is the priority intervention as it binds with digoxin, preventing further absorption in the gastrointestinal tract. This helps reduce the amount of digoxin available for systemic circulation and minimizes its toxic effects. Gastric lavage is no longer recommended due to potential complications and lack of evidence of efficacy. Obtaining an electrocardiogram may help assess the effects of digoxin toxicity, but it is not the initial priority. IV digoxin immune fab (Digibind) is used in severe cases of digoxin toxicity but is not the first-line intervention.

3. What is the best response for a two-year-old boy who begins to cry when the mother starts to leave?

• A. Let's wave bye-bye to mommy.
• B. Two-year-olds usually stop crying the minute the parent leaves.
• C. Now be a big boy. Mommy will be back soon.
• D. Let's wave bye-bye to mommy.

Correct answer: D

Rationale: The best response for a two-year-old boy who begins to cry when the mother starts to leave is to wave bye-bye to mommy. This action helps the child understand that the separation is temporary and gives him a sense of closure. Choice A is the correct answer. Choice B is incorrect as it generalizes the behavior of two-year-olds. Choice C may invalidate the child's feelings by telling him to 'be a big boy' instead of acknowledging his emotions and providing comfort.

4. A 3-year-old child is admitted to the hospital with severe dehydration. The healthcare provider prescribes an IV infusion of 0.9% normal saline. The nurse notes that the child’s heart rate is 150 beats per minute, and the blood pressure is 90/50 mm Hg. What should the nurse do first?

• A. Administer the IV fluids as prescribed
• B. Notify the healthcare provider
• C. Check the child’s urine output
• D. Reassess the child’s vital signs in 30 minutes

Correct answer: A

Rationale: In a pediatric patient with severe dehydration and signs of compromised hemodynamics such as tachycardia (heart rate of 150 bpm) and hypotension (blood pressure of 90/50 mm Hg), the priority intervention is to administer IV fluids as prescribed. Immediate fluid resuscitation is essential to restore hydration, improve perfusion, and stabilize the child's vital signs. While it's important to monitor urine output, initiating fluid resuscitation takes precedence in this situation. Notifying the healthcare provider can cause a delay in critical intervention, and waiting to reassess vital signs in 30 minutes can be detrimental in a child with severe dehydration and compromised hemodynamics.

5. The healthcare provider is assessing an infant with diarrhea and lethargy. Which finding should the provider identify that is consistent with early dehydration?

• A. Tachycardia
• B. Bradycardia
• C. Dry mucous membranes
• D. Decreased skin turgor

Correct answer: A

Rationale: Tachycardia is a common early sign of dehydration in infants. It is important for healthcare providers to be vigilant in monitoring infants with these symptoms, as prompt intervention is crucial to prevent further complications.
