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 C
Explanation
A. "Your child's diet should be high in carbohydrates & proteins with no restriction of fats."
This statement is not entirely accurate. While it's true that children with cystic fibrosis often require a diet that is higher in calories and protein to support growth and weight gain, there is typically a need to restrict fat intake. Pancreatic insufficiency, which is common in cystic fibrosis, can lead to malabsorption of fats and fat-soluble vitamins. Therefore, a dietitian may recommend enzyme replacement therapy and a diet that is moderate in fat but high in calories and protein.
B. "Limit your child's intake of sodium to avoid complications."
This statement is not accurate. Cystic fibrosis can lead to excessive loss of salt in sweat, which can contribute to dehydration and electrolyte imbalances. Therefore, limiting sodium intake can cause electrolyte disturbances.
C. "A pigeon-shaped chest might become evident as the disease progresses."
This statement is accurate. Cystic fibrosis can cause chronic lung infections and inflammation, leading to structural changes in the chest over time. One common manifestation is a barrel-shaped or "pigeon-shaped" chest, which can occur as the disease progresses. This may result from hyperinflation of the lungs due to air trapping and chronic respiratory compromise.
D. "Administer a bronchodilator to the child after chest percussion therapy."
This statement is not necessarily accurate or applicable to all cases. Bronchodilators are medications used to help relax and open the airways in conditions such as asthma or chronic obstructive pulmonary disease (COPD). While bronchodilators may be part of the treatment regimen for some individuals with cystic fibrosis, their use after chest percussion therapy would depend on the individual's specific respiratory symptoms and treatment plan. It's important for the parents to follow the healthcare provider's instructions regarding medication administration.
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.
