A 4-year-old child who weighs 44 lbs is diagnosed with Streptococcal Pharyngitis and is prescribed Penicillin. 40 mg/kg/day, twice a day for 10 days. The suspension is written as 400 mg/5 ml. Calculate one dose in mg.
400 mg.
800 mg.
1200 mg.
1600 mg.
The Correct Answer is A
Choice A rationale:
The dosage prescribed for the child is 40 mg/kg/day, twice a day for 10 days. The child weighs 44 lbs, which is approximately 20 kg (1 lb = 0.45 kg). Therefore, the total daily dosage would be 40 mg/kg * 20 kg = 800 mg. This is split into two doses, so each dose would be 400 mg, not 400 mg per 5 ml as in the suspension.
Choice B rationale:
As explained above, the total daily dosage is 800 mg, split into two doses of 400 mg each. The suspension is written as 400 mg/5 ml, so one dose would be 400 mg.
Choice C rationale:
This choice is incorrect because it does not accurately calculate the dosage based on the child's weight and the prescribed dosage regimen.
Choice D rationale:
This choice is incorrect because it suggests a higher dose than what is prescribed. The correct dosage, based on the child's weight and prescription, is 800 mg per day, split into two doses of 400 mg each.

Correct Answer is B
Explanation
Choice A rationale:
Inspiratory stridor. Inspiratory stridor, a high-pitched sound heard during inhalation, is a common symptom of acute epiglottitis. It is caused by the swelling and inflammation of the epiglottis, which can partially obstruct the airway and create a stridor sound during breathing.
Choice B rationale:
Complete obstruction. Using a tongue depressor to examine the throat of a child with acute epiglottitis can potentially lead to a complete airway obstruction. The epiglottis, which is already swollen, can block the airway entirely, leading to respiratory distress and potentially a life-threatening situation.
Choice C rationale:
Sore throat. A sore throat is a common symptom of various respiratory tract infections, including acute epiglottitis. However, the use of a tongue depressor can worsen the swelling and potentially lead to complete airway obstruction, which is a more immediate concern.
Choice D rationale:
Respiratory tract infection. Acute epiglottitis itself is a severe respiratory tract infection, specifically involving the epiglottis. Using a tongue depressor might exacerbate the condition, leading to airway obstruction, but it is not the cause of the respiratory tract infection.
Correct Answer is ["C","D","E"]
Explanation
The correct answer ischoices A, C, D, and E.
Choice A rationale:
A respiratory rate of 36 breaths/minute at rest is concerning in a pediatric client, as it may indicate respiratory distress or an underlying respiratory condition.
Choice B rationale:
An increasing appetite is generally a positive sign and not typically concerning unless accompanied by other symptoms.
Choice C rationale:
A temperature above 37.7° C (100° F) is concerning as it indicates fever, which could be a sign of infection or other medical conditions.
Choice D rationale:
New, frequent coughing is concerning as it may indicate respiratory infections, asthma, or other respiratory issues.
Choice E rationale:
Turning blue or bluer than normal (cyanosis) is a serious symptom indicating inadequate oxygenation and requires immediate medical attention.
