An infant who weighs 22 lb receives a prescription for amoxicillin 20 mg/kg/day PO in divided doses every 8 hours. The bottle is labeled, "Amoxicillin for Oral Suspension, USP 250 mg per 5 mL." How many mL should the nurse administer with each dose? (Enter numerical value only. If rounding is necessary, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["1.3"]

To calculate the dosage of amoxicillin for the infant, first convert the weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The infant weighs 22 pounds, which is equivalent to 10 kilograms (22 lb / 2.2 lb/kg). The prescription is for 20 mg/kg/day, so the total daily dosage is 200 mg (10 kg * 20 mg/kg). This total daily dosage is divided into three doses, as it is to be administered every 8 hours, resulting in

66.7 mg per dose (200 mg / 3). The medication is supplied as 250 mg per 5 mL, so to find out how many mL per dose, set up a proportion: 250 mg is to 5 mL as 66.7 mg is to X mL. Solving for X gives us 1.334 mL (66.7 mg * 5 mL / 250 mg), which rounds to 1.3 mL when rounded to the nearest tenth.

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

Explanation

A. Not a priority compared to monitoring vital signs and ensuring adequate oxygenation.

B: Increased oxygen flow is necessary to manage the client's respiratory distress and history of smoking. Correct Answer: 3 L, not 1 L as initially listed.
C: Acetaminophen 350 mg PO q4h for temperature greater than 101 F (38.3°C): Important for fever management but not the first priority in acute respiratory distress.
D: Helps maintain hydration but is secondary to respiratory support in this scenario.

E: Not applicable as there is no immediate need for surgery or risk of aspiration currently indicated.
F: Important for medication administration and fluid balance but follows after ensuring respiratory function.
G: Useful for diagnosing the cause of respiratory symptoms but not a first-line action.

H: Essential for continuously assessing the client's respiratory and cardiac status due to difficulty breathing.

A. Heart rate 121 beats/minute B. Capillary refill 2 seconds C. Respirations 28 breaths/minute with shallow breathing D. Radial and pedal pulses 2+ E. Severe abdominal pain in right lower quadrant F. Feels anxious G. Temperature 100.8° F (38.2° C) H. Vomiting small amounts of green bile I. Blood pressure 115/76 mm Hg

Correct Answer is ["A","C","E","G","H"]

Explanation

A. Tachycardia indicates the body is responding to pain, infection, or potential sepsis. It's a critical vital sign indicating the body's stress response.
B. Tachypnea can be a response to pain or anxiety but also indicates the need for careful monitoring of respiratory status, especially postoperatively.

C. A capillary refill of 2 seconds is within the normal range and indicates adequate peripheral perfusion.
D. Radial and pedal pulses 2+ are within the normal range and indicates adequate peripheral perfusion.
E. Severe abdominal pain in the right lower quadrant is a primary symptom of appendicitis, which is confirmed by the CT scan showing a dilated appendix and fat stranding. Immediate attention is needed to address potential complications such as rupture.
F. Feeling anxious needs to be managed to promote patient comfort. However, it doesn’t need to be managed immediately since it is not life-threatening.
G. Fever is a sign of infection or inflammation, common in appendicitis. Monitoring and managing fever is crucial in preventing further complications.
H. Bilious vomitus is a common finding in appendicitis and may indicate that the inflammation has progressed to a point where it is causing a blockage in the intestines. This obstruction can lead to increased pressure within the abdominal cavity and compromise blood flow, potentially resulting in a life-threatening situation.
I. A blood pressure of 115/76 mm Hg is within normal limits and indicates stable hemodynamics at this point.
