A dehydrated child has intravenous aid therapy ordered. The child weighs 10 kg. Physician ordered Lactated Ringer's solution 40 ml/kg over 4 hours How many miles per hour will this child receive?
300ml/hour
100 mL/hour
50mL/hour
200 ml/hour
The Correct Answer is B
Infusion rate (mL/hour) = Total volume (mL) / Total time (hours)
Given:
Child's weight: 10 kg
Ordered volume: 40 mL/kg
Total time: 4 hours
First, calculate the total volume of Lactated Ringer's solution needed:
Total volume = 40 mL/kg × 10 kg = 400 mL
Then, divide the total volume by the total time to find the infusion rate:
Infusion rate = 400 mL / 4 hours = 100 mL/hour

Correct Answer is A
Explanation
A. Give the child a stuffed animal: Providing a comforting item like a stuffed animal can help the child feel more secure and may offer some comfort during the parent's absence. This option is appropriate as it addresses the child's emotional needs.
B. Inform the child that her parent will be back in 2 hours: While it's helpful to provide reassurance to the child, a 2-year-old may not fully understand the concept of time, and telling them that their parent will return in 2 hours may not effectively alleviate their distress. This option may not be as immediately comforting as providing a tangible source of comfort.
C. Call the parent to return to the child's room: If possible, having the parent return to the child's room can provide the most direct comfort and reassurance to the child during a tantrum. However, it may not always be feasible for the parent to return immediately, especially if they are occupied or attending to other responsibilities.
D. Leave the child alone in the room for 5 minutes: Leaving the child alone during a tantrum can exacerbate feelings of distress and abandonment, potentially escalating the situation further. It's essential to provide support and reassurance to the child during moments of distress rather than leaving them alone.
Correct Answer is B
Explanation
A. Drooling:
Drooling can occur post-tonsillectomy due to throat discomfort or swelling. However, it is not specific to hemorrhage. It may result from pain, swelling, or difficulty swallowing.
B. Continuous swallowing:
Continuous swallowing is indeed a clinical manifestation of hemorrhage after a tonsillectomy. The presence of blood in the throat triggers the swallowing reflex, leading to frequent swallowing by the patient. This symptom is characteristic of hemorrhage and requires immediate medical attention.
C. Poor fluid intake:
Poor fluid intake can occur post-tonsillectomy due to pain, discomfort, or nausea. While it can be a concern for overall recovery, it is not specific to hemorrhage.
D. Increased pain:
Increased pain can be associated with hemorrhage, especially if it is sudden, severe, or worsening. However, it is not as specific as continuous swallowing in indicating hemorrhage post-tonsillectomy. Increased pain can also be due to various other reasons such as inflammation, infection, or trauma.
