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 A

Explanation

A. Digoxin:Digoxin is a cardiac glycoside that can cause toxicity if the heart rate is too low. For infants, the apical pulse should typically be greater than 90-110 beats per minute before administration. Since this infant has an apical pulse of 88 beats/minute, the nurse should withhold digoxin and notify the healthcare provider for further evaluation.

B. Enalapril:Enalapril is an ACE inhibitor used to treat heart failure and hypertension. It can generally be administered as prescribed, regardless of the current heart rate, but blood pressure should be monitored.

C. Furosemide:Furosemide is a diuretic commonly used in heart failure management to reduce fluid overload. It can be administered safely at this time, as it does not have the same pulse considerations as digoxin.

D. Hydralazine:Hydralazine is a vasodilator used to manage hypertension and improve cardiac output. It can be administered without concern for the current heart rate, although blood pressure should be monitored.

A. Breastfeed frequently. B. Position prone after feeding. C. Avoid smoke exposure. D. Inspect the infant's ears daily

Correct Answer is C

Explanation

A. Breastfeeding frequently is generally recommended for infant health, but it is not specifically related to preventing otitis media recurrence. It has other health benefits for infants.

B. Positioning the infant prone (face down) after feeding is not recommended, and it does not relate to preventing otitis media recurrence. The recommended sleep position for infants is on their back to reduce the risk of sudden infant death syndrome (SIDS).

C. Avoiding smoke exposure is a crucial instruction for preventing otitis media recurrence. Exposure to secondhand smoke is a known risk factor for ear infections in children. It can lead to increased susceptibility to respiratory infections, which can subsequently increase the risk of otitis media.

D. Inspecting the infant's ears daily is not a primary preventive measure for otitis media recurrence. While it's essential to monitor the child's health, checking the ears daily is not a standard practice for preventing ear infections.
