A nurse is preparing to administer azithromycin oral suspension 10 mg/kg/day to a 15-month- old infant who has otitis media. The infant weighs 22 Ib. The amount available is azithromycin oral suspension 200 mg/5 mL. How many mL should the nurse plan to administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2.5"]
- Convert the infant's weight from pounds to kilograms: 22 Ib / 2.2 = 10 kg
- Calculate the daily dose of azithromycin: 10 mg/kg/day x 10 kg = 100 mg/day
- Calculate the volume of azithromycin oral suspension needed: 100 mg/day / (200 mg/5 mL) = 2.5 mL/day
- Round the answer to the nearest tenth: 2.5 mL/day
- The nurse should plan to administer 2.5 mL of azithromycin oral suspension to the infant.

Correct Answer is D
Explanation
A: Introducing fruit juice at 4 months old is not recommended because infants' digestive systems are not yet ready for such foods, and it can increase the risk of tooth decay and obesity.
B: Introducing eggs at 6 months could be appropriate; however, it is not the best choice as it does not reflect the gradual introduction of new foods one at a time, which is essential to monitor for any allergic reactions or food intolerances.
C: Offering cereal with a percent of milk is not advisable for a 4-month-old infant as cow's milk should not be introduced until the child is at least 12 months old due to the risk of iron deficiency and potential allergies.
D: Offering a new food every 7 days is the correct approach as it allows parents to introduce new foods gradually and monitor the infant for any adverse reactions or allergies, which aligns with the guidelines provided by health authorities.
Correct Answer is D
Explanation
Choice A reason:
A temperature of 37.7° C (99.9° F) is slightly elevated but not a cause for immediate concern after immunization. It can be a normal response.
Choice B reason:
Redness at the injection site is a common and expected reaction after immunization. It does not require immediate intervention.
Choice C reason:
Prolonged crying can occur after immunization, but it is not a priority over a potential allergic reaction indicated by hives.
Choice D reason:
Hives on the child's neck indicate a potential allergic reaction to the immunization. This is a priority finding and requires immediate attention from the nurse.
