A child is ordered levothyroxine 25mcg daily for congenital hypothyroidism. The medication is supplied in 0.5mg/5mL liquid suspension. How many milliliters would be administered? (Round to the hundredth place, Use a leading zero if it applies, do not use a trailing zero,)
The Correct Answer is ["0.25"]
Ordered dose = 25 mcg
Available concentration = 0.5 mg/5 mL = 500 mcg/5 mL = 100 mcg/mL
Volume needed = Desired dose ÷ Concentration = 25 mcg ÷ 100 mcg/mL = 0.25 mL
Final Answer: 0.25 mL

Correct Answer is A
Explanation
A. A series of casts will be made for the infant soon after birth. The Ponseti method, the gold standard for treating clubfoot, involves gentle manipulation of the foot and application of a series of plaster casts that are changed weekly. This treatment usually begins shortly after birth to take advantage of the newborn’s soft tissues and bones, which are more easily repositioned.
B. An orthotic brace at 6 months of age is not the initial treatment. Bracing is used later in the treatment process after the foot has been corrected with casting to maintain alignment and prevent relapse.
C. Surgery performed in utero is not a treatment option for clubfoot. In severe cases unresponsive to casting, surgery may be required after birth, but intrauterine correction is not standard practice.
D. Monitoring and physical therapy alone are not sufficient to correct clubfoot. Without casting or surgical intervention, the deformity will persist and lead to long-term mobility issues.
Correct Answer is C
Explanation
A. Sitting upright may help with drainage and comfort once the child is more awake, but immediately post-op, it is not the safest initial position because the child may still be drowsy from anesthesia and at risk for airway obstruction.
B. Prone position alone does allow secretions to drain forward, but it is not always the most comfortable or safest option for all children.
C. Prone or side-lying position is the priority immediately after a tonsillectomy. These positions facilitate drainage of secretions, reduce the risk of aspiration, and help maintain a patent airway while the child is recovering from anesthesia. Once fully awake and alert, the child may then be positioned upright if tolerated.
D. Lying flat on the back increases the risk of airway obstruction and aspiration from blood or secretions, making it unsafe post-operatively.
