The healthcare provider prescribed amoxicillin 20 mg/kg by mouth (PO) every 8 hours for a toddler with otitis media who weighs 33 pounds (15 kg). The medication is labeled, "125 mg/5mL." How many mL should the nurse administer?

(Enter the numerical value only. If rounding required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["12"]

To calculate the amount of amoxicillin in mL to administer to a toddler weighing 15 kg, you can use the following calculation:

Dose (in mg) = Weight (in kg) x Dose (in mg/kg)

Dose (in mg) = 15 kg x 20 mg/kg = 300 mg

Now, you want to convert the dose to mL using the provided concentration:

Concentration = 125 mg/5 mL

Now, calculate the mL needed:

Volume (in mL) = Dose (in mg) / Concentration (in mg/mL)

Volume (in mL) = 300 mg / 125 mg/5 mL = 12 mL

So, the nurse should administer 12 mL of amoxicillin.

Correct Answer is ["B","C"]

Explanation

B. Check pedal pulses every 4 hours: This order should be questioned because after a ventricular septal defect closure, it is essential to assess and monitor peripheral pulses frequently, especially in the immediate post-catheterization period. Checking pedal pulses every 4 hours may not provide adequate monitoring and could potentially lead to delayed detection of complications.

C. Give lactated Ringers intravenously at 66 ml/hr while NPO: This order should be questioned because it specifies a continuous intravenous infusion of lactated Ringer's solution, but the patient is listed as "Nothing by mouth" (E). In cases where a patient is NPO, it's important to clarify the rationale for the intravenous fluid rate and consider whether it's appropriate, especially after a cardiac catheterization procedure.

The other orders are appropriate or necessary for the post-catheterization care of a child with a closed ventricular septal defect:

A. Point of care blood glucose: Monitoring blood glucose levels is relevant in post-catheterization care.

D. Vital signs every 4 hours: Monitoring vital signs is standard post-catheterization care.

F. Admit to the pediatric floor for observation: This order is appropriate for post-catheterization observation.

G. Check dressing every 15 minutes for 1 hour and then every hour: Frequent dressing checks are important for assessing and preventing bleeding or other complications at the catheterization site.

H. Place the child on a continuous cardiopulmonary monitor: Continuous monitoring is important for early detection of any cardiopulmonary issues in the post-catheterization period.

In summary, monitoring peripheral pulses and the appropriateness of intravenous fluids in relation to NPO status should be questioned in this context.

A. Electrocardiogram: Tall T wave and widened QRS complex B. Blood pressure: 126/76 mm Hg C. Basilar crackles D. Urine output: 20 mL in the last hour E. Respirations: 26 breaths/minute F. Heart rate: 72 beats/minute G. Oxygen saturation 98% on room air H. A normal body temperature (98.9°F or 37.1°C orally).

Correct Answer is ["B","F","G","H"]

Explanation

A. An electrocardiogram with a tall T wave and widened QRS complex may indicate electrolyte imbalances or cardiac issues, which are not indicative of stabilization.

C. Basilar crackles can be a sign of pulmonary or cardiac issues and are not indicative of stabilization.

D. A urine output of 20 mL in the last hour may suggest reduced kidney function or hydration status and is not indicative of stabilization.

E. A respiratory rate of 26 breaths/minute may indicate respiratory distress and is not indicative of stabilization.

The assessment findings that suggest stabilization include:

A blood pressure within the normal range (126/76 mm Hg).

A heart rate within the normal range (72 beats/minute).

Oxygen saturation of 98% on room air, indicating adequate oxygenation.

A normal body temperature (98.9°F or 37.1°C orally).

These vital signs and clinical parameters are within normal ranges, suggesting that the client's condition is stable at this time.
