An infant who weighs 22 pounds receives a prescription for amoxicillin 20 mg/kg/day by mouth 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.)
The Correct Answer is ["1.3"]
1. Convert the infant's weight from pounds to kilograms. We can use the conversion factor 1 kg
= 2.2 lb. So, 22 lb x (1 kg / 2.2 lb) = 10 kg.
2. Calculate the total daily dose of amoxicillin for the infant. We can use the formula D = d x W, where D is the total daily dose, d is the dose per kg per day, and W is the weight in kg. So, D = 20 mg x 10 kg = 200 mg.
3. Calculate the single dose of amoxicillin for the infant. We can divide the total daily dose by the number of doses per day. Since the prescription is for every 8 hours, there are 3 doses per day. So, 200 mg / 3 = 66.67 mg.
4. Calculate the volume of amoxicillin suspension for the single dose. We can use the ratio of the concentration of the suspension, which is 250 mg per 5 mL. So, 66.67 mg x (5 mL / 250 mg) =
1.33 mL.
5. Round the volume to the nearest tenth= 1.3 mL

Correct Answer is D
Explanation
A) Incorrect- Reviewing transcutaneous bilirubin levels is unrelated to the presence of an enlarged clitoris. Bilirubin levels are typically assessed to monitor jaundice in newborns.
B) Incorrect- Observing and palpating breast tissue for enlargement is not relevant to the condition of salt-wasting congenital adrenal hyperplasia. Breast tissue enlargement would not be associated with this hormonal disorder.
C) Incorrect- Assessing for signs of fluid retention and bilateral pedal edema is important for monitoring for other conditions, but it is not relevant to the enlarged clitoris seen in this specific scenario.
D) Correct- Salt-wasting congenital adrenal hyperplasia is a genetic disorder that results in a deficiency of certain enzymes required for cortisol and aldosterone production. This deficiency leads to an overproduction of androgens, which can cause virilization of female external genitalia. The enlarged clitoris is a result of increased androgen levels. Explaining this finding to the mother provides her with accurate information about the condition and its effects on the infant's anatomy.
Correct Answer is D
Explanation
A) Incorrect - Encouraging the use of ice on the areola is not a recommended intervention for addressing inverted nipples and promoting successful breastfeeding.
B) Incorrect - Teaching about the use of a breast pump might be useful for milk expression but may not directly address the issue of latching due to inverted nipples.
C) Incorrect - Offering supplemental formula feedings does not address the underlying issue of inverted nipples and breastfeeding difficulties.
D) Correct-inverted nipples can make breastfeeding challenging as the baby may have difficulty latching directly onto the breast. A breast shield can be recommended to help draw out the nipple and create a more optimal shape for latching. It can also provide a larger surface area for the baby to grasp onto, making breastfeeding more successful for both the mother and the baby.
