Final answer:
Without the specific dosage recommendation for the infant's weight, it is not possible to determine the amount of suspension to administer safely. Units are essential in medical dosing to avoid harmful consequences.
Step-by-step explanation:
The student has asked how many milliliters of a suspension should be given to an infant weighing 14 pounds. To answer this question accurately, additional information is needed such as the dosage recommendation per unit of body weight for the infant. Without this critical dosage information, which is usually specified by a healthcare provider, we cannot safely determine the amount of suspension to administer.
It is necessary to know the dosage per pound or kilogram in order to calculate the total milliliters required for a child of a specific weight. Units are essential in medical dosing to ensure safety and efficacy, as exemplified by the difference in consequences between administering 100 mg versus 100 g of phenobarbital.
