Final answer:
A nurse needs to consult the MAR and medication reference for the lowest recommended daily dosage of penicillin G for a child. Dosages depend on various patient factors, and without direct reference information, the exact dosage cannot be provided.
Step-by-step explanation:
The question relates to the administration of penicillin G intravenously to a child. A nurse is required to verify the lowest recommended units per day of penicillin G for safe and effective patient care. Exact dosages can vary based on individual patient factors including age, weight, and the severity of the infection, and thus require a consultation of the MAR (Medication Administration Record) and medication reference materials. In general practice for dosage calculations, converting from one unit of measurement to another is vital, akin to converting 50 mg aspirin tablets to the amount needed for a 0.2 g dose.
However, without specific reference information provided regarding the lowest recommended daily dosage of penicillin G for children, it is not possible to provide a direct answer to this question. It's critical for healthcare providers to reference pharmacological guidelines and consider patient-specific information when determining dosages for medications.
