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 B
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 C
Explanation
Choice A rationale:
Signs of stress can indeed manifest in various ways, including stomach pains and changes in behavior. However, in this scenario, the child's symptoms of stomach pains, aggression, and stubbornness might indicate a physical problem causing emotional stress. It's essential to consider other possibilities before attributing the symptoms solely to stress.
Choice B rationale:
Developmental delay could be a potential cause of behavioral issues in a child, but it doesn't explain the stomach pains. Moreover, a developmental delay would typically have been identified earlier in the child's life through regular screenings and assessments.
Choice C rationale:
A physical problem causing emotional stress, such as an undiagnosed medical condition, can lead to both stomach pains and behavioral changes. Considering this possibility is crucial in this situation. It's essential to conduct a thorough physical examination and medical evaluation to rule out any underlying health issues.
Choice D rationale:
Lack of adjustment to the school environment could contribute to behavioral problems in a child. However, it's essential to first investigate the physical symptoms, like stomach pains, before solely attributing the behavior to school adjustment issues. Physical health should be thoroughly assessed to rule out any medical causes for the symptoms.
Correct Answer is B
Explanation
Choice A rationale:
Performing 100 Kegel exercises each day is not necessary and might lead to muscle fatigue. The number of exercises can vary from person to person. Quality is more important than quantity when performing Kegel exercises.
Choice B rationale:
This statement indicates a correct understanding of Kegel exercises. Holding the contraction for 10 seconds and then resting for 10 seconds between exercises is a common and effective technique. Kegel exercises help strengthen the pelvic floor muscles, which can be beneficial during pregnancy and after childbirth.
Choice C rationale:
There is no requirement to perform Kegel exercises only in the sitting position. These exercises can be done in various positions, such as sitting, standing, or lying down, depending on the individual's comfort.
Choice D rationale:
Performing Kegel exercises throughout pregnancy, starting early and continuing postpartum, can provide optimal benefits. There's no need to wait until the last trimester to start these exercises. Regular practice can help improve pelvic muscle tone and prevent issues such as urinary incontinence.
