To determine whether the prescribed dose of Vibramycin (doxycycline) is safe for a child weighing 30 pounds, we'll perform the following steps:

1. **Convert the Child's Weight from Pounds to Kilograms**
2. **Calculate the Total Daily Prescribed Dose**
3. **Determine the Recommended Daily Dosage Range**
4. **Compare the Prescribed Dose with the Recommended Range**

Let's go through each step in detail.

---

### 1. Convert the Child's Weight from Pounds to Kilograms

**Given:**
- Weight = 30 pounds (lb)

**Conversion Factor:**
- $$ 1 \text{ kg} = 2.2 \text{ lb} $$

**Calculation:**
$$
\text{Weight in kg} = \frac{30 \text{ lb}}{2.2 \text{ lb/kg}} \approx 13.64 \text{ kg}
$$

---

### 2. Calculate the Total Daily Prescribed Dose

**Given:**
- Dose per administration = 50 mg
- Frequency = every 12 hours (q 12 h)

**Number of Doses per Day:**
$$
\text{Doses per day} = \frac{24 \text{ hours}}{12 \text{ hours/dose}} = 2 \text{ doses/day}
$$

**Total Daily Dose:**
$$
\text{Total daily dose} = 50 \text{ mg/dose} \times 2 \text{ doses/day} = 100 \text{ mg/day}
$$

---

### 3. Determine the Recommended Daily Dosage Range

**Given:**
- Recommended dosage range = 2.2 to 4.4 mg/kg/day

**Calculation:**
$$
\text{Minimum recommended dose} = 2.2 \text{ mg/kg/day} \times 13.64 \text{ kg} \approx 30 \text{ mg/day}
$$
$$
\text{Maximum recommended dose} = 4.4 \text{ mg/kg/day} \times 13.64 \text{ kg} \approx 60 \text{ mg/day}
$$

**Recommended Dosage Range:**
$$
30 \text{ mg/day} \leq \text{Recommended dose} \leq 60 \text{ mg/day}
$$

---

### 4. Compare the Prescribed Dose with the Recommended Range

**Prescribed Total Daily Dose:**
$$
100 \text{ mg/day}
$$

**Recommended Daily Dose Range:**
$$
30 \text{ mg/day} \leq \text{Recommended dose} \leq 60 \text{ mg/day}
$$

**Analysis:**
$$
100 \text{ mg/day} > 60 \text{ mg/day (Maximum Recommended Dose)}
$$

---

### **Conclusion**

The prescribed total daily dose of **100 mg/day** exceeds the **maximum recommended dosage of 60 mg/day** for a child weighing 30 pounds (approximately 13.64 kg).

**Therefore, the dose is **not safe** and should be re-evaluated to align with the recommended dosage guidelines.**

---

**Recommendation:** Always consult with a healthcare professional before making any changes to medication dosages.
The prescribed dose of 100 mg/day is higher than the recommended maximum of 60 mg/day for a 30-pound child. Therefore, the dose is not safe and should be reviewed by a healthcare professional.
