A nurse is preparing to administer ampicillin to a school-age child who weighs 55 lb. The provider prescribes 50 mg/kg/day in 4 equal doses. Available is ampicillin oral suspension 125 mg/5 mL. How many mL should the nurse administer with each dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["12.5"]
To calculate the dosage, first convert the child's weight to kilograms (1 kg = 2.2 lbs), so 55 lbs is approximately 25 kg. The total daily dose of ampicillin prescribed is 50 mg/kg/day, which for a 25 kg child is 1250 mg/day (50 mg/kg * 25 kg). This total daily dose should be divided into 4 equal doses, resulting in 312.5 mg per dose (1250 mg/day ÷ 4 doses/day). The concentration of the ampicillin suspension is 125 mg/5 mL, so to find out how many mL per dose, divide the dose in mg by the concentration and multiply by the volume: 312.5 mg per dose ÷ 125 mg/5 mL = 2.5 * 5 mL = 12.5 mL per dose. Therefore, the nurse should administer 12.5 mL per dose.

Correct Answer is ["A","B","C","E","F"]
Explanation
Deep Tendon Reflexes 4+: This indicates hyperreflexia, which can be associated with electrolyte imbalances, particularly magnesium deficiency, or central nervous system issues. In this context, the client has a low magnesium level (0.7 mEq/L), which can cause neuromuscular irritability and potentially dangerous complications.
Generalized Weakness and Mild Leg Cramping: While muscle strength is reported as equal, the generalized weakness and cramping suggest possible electrolyte imbalances or neurological issues. The combination with low magnesium levels raises concern for further complications.
Heart Rate Irregular: An irregular heart rate can indicate potential cardiac issues, especially in the context of electrolyte imbalances such as hypomagnesemia and the use of hydrochlorothiazide, which can contribute to electrolyte disturbances.
Bowel Sounds Hyperactive x 4 Quadrants: Although hyperactive bowel sounds can be associated with various conditions, in this case, they may be linked to the client's history of vomiting and possible electrolyte imbalance, warranting follow-up to ensure appropriate management of gastrointestinal symptoms.
