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

Explanation

A. Evaluating the infant for failure to thrive (FTT) is not the most appropriate initial intervention in this case. FTT is a long-term growth issue, and the immediate concern is the infant's current symptoms and cardiac status.

B. Auscultate heart and lungs while the infant is held.

Tetralogy of Fallot (TOF) is a congenital heart defect that includes four specific cardiac abnormalities, and it often requires surgical correction in infancy. When an infant with a history of TOF surgery presents with symptoms such as rapid breathing, feeding difficulties, and fatigue, it may raise concerns about potential cardiac issues or complications.

The most appropriate initial intervention is to auscultate the infant's heart and lungs while the infant is held to assess for any abnormal heart sounds or signs of respiratory distress. Auscultation can provide important information about the infant's cardiac and respiratory status. This assessment will help determine if there are any immediate concerns related to the infant's cardiac condition.

C. Stimulating the infant to cry to produce cyanosis is not a recommended or appropriate intervention. Cyanosis is a sign of inadequate oxygenation and should not be induced in a child.

D. Obtaining a 12-lead electrocardiogram may be indicated if there are significant concerns about the infant's cardiac status, but auscultation should be performed first to assess the immediate condition. An electrocardiogram is a diagnostic tool and would be ordered as a follow-up assessment if needed.

A. Jaundice. B. Chest pain. C. Swelling in the hands or feet. D. Ulcers on the legs

Correct Answer is B

Explanation

A. Jaundice is a common finding in individuals with sickle cell disease due to the breakdown of sickled red blood cells. While jaundice should be monitored and reported, it is not as immediately concerning as chest pain in the context of a sickle cell crisis.

B Chest pain.

Sickle cell disease is characterized by the presence of abnormal hemoglobin that can lead to the formation of sickled red blood cells. During a sickle cell crisis, these abnormal cells can block blood vessels, leading to tissue damage and severe pain. Chest pain in a child with sickle cell disease can be indicative of a potentially life-threatening complication called acute chest syndrome, which is a serious condition that requires immediate medical attention. Acute chest syndrome can lead to impaired oxygen exchange and respiratory distress, making it a medical emergency.

C. Swelling in the hands or feet can be associated with vaso-occlusive episodes in sickle cell disease, but it may not be as immediately concerning as chest pain.

D. Ulcers on the legs can be a complication of sickle cell disease, but they are not typically as acutely life-threatening as chest pain due to acute chest syndrome.

Chest pain should be treated as a medical emergency in a child with sickle cell disease during a sickle cell crisis, and the healthcare provider should be informed immediately to initiate appropriate intervention.
